Abstract Introduction: The limited availability of data in Chile on the use of diagnostic images (DI) poses a challenge in the efficient management of resources. Objective: To quantify and characterize the use of DI in hospitalized subjects in Chile for 1 year. Method: Descriptive population based study on the use of DI in Chile during 2019 in hospitalized subjects using an official national database recorded with the diagnosis-related groups (DRG) system. Demographic variables related to hospitalization and derived from the DRG were analyzed. Results: 55.5% of hospital events involved at least one DI (n = 466,306). The most used imaging technique was radiography/X-ray (36.4%), followed by computed tomography (35%). The Magallanes and Aysén regions exhibited the highest DI rates. Hospitalized patients who required some DI had an average of days of hospitalization and mortality rate that were 3.4 and 5.5 times greater than those who did not require DI (p < 0.01). Conclusions: There are important geographical differences in the use of DI in Chile. Our description will facilitate future studies that delve deeper and explore access or socioeconomic differences.

Resumen Introducción: La escasa disponibilidad de datos en Chile sobre el uso de imágenes diagnósticas (ID) plantea un desafío en la gestión eficiente de recursos. Objetivo: Cuantificar y caracterizar el uso de ID en sujetos hospitalizados en Chile durante 1 año. Método: Estudio poblacional descriptivo sobre el uso de ID en Chile durante el año 2019 en sujetos hospitalizados utilizando una base de datos nacional oficial consignada con la herramienta de grupos relacionados a diagnósticos (GRD). Se analizaron variables demográficas, relativas a la hospitalización y derivadas de los GRD. Resultados: El 55,5% de los eventos hospitalarios involucró al menos una ID (n = 466.306). La modalidad de imagen más utilizada fue la radiografía (36,4%), seguida por la tomografía computada (35%). Las regiones de Magallanes y Aysén exhibieron las tasas de ID más altas. Los pacientes hospitalizados que requirieron alguna ID obtuvieron unos promedios de días de hospitalización y letalidad 3,4 y 5,5 veces mayores que los que no requirieron ID (p < 0,01). Conclusiones: Existen importantes diferencias geográficas en la utilización de ID en Chile. Nuestra descripción facilitará la realización de futuros estudios que profundicen y exploren las diferencias en el acceso o socioeconómicas.

Abstract The transnational collective action in defense of voluntary abortion, known as the “green tide” since the end of 2017, is here to stay and has attracted the attention of the media, academics, and governments. The emergence of this phenomenon, current and in movement, has been studied and analyzed from various perspectives that have enriched our understanding of it. However, it has not been explored much from the analytical perspective of regional governance, as a framework to consider the influence of this phenomenon on rule negotiation processes. This article seeks to contribute to the analysis of the situation of abortion rights in Latin America and the Caribbean within this framework and through a qualitative methodology. The article examines the contributions of transnational articulations of abortion activists and official documents of international organizations, within a novel perspective that combines studies of global governance and critical feminist approaches to international relations. With the aim of underscoring some pending challenges, in addition to highlighting important achievements, it is concluded that the place occupied in multilateral negotiation processes by transnational feminist movements and articulations that fight for expanded rights is significant.

Resumen La acción colectiva transnacional en defensa del aborto voluntario, conocida como la “marea verde” desde finales de 2017, llegó para quedarse y ha llamado la atención de los medios de comunicación, de los estudios académicos y de los Gobiernos. El surgimiento de este fenómeno, vigente y en movimiento, es estudiado y analizado desde diversos enfoques que han enriquecido su comprensión. Sin embargo, poco se ha explorado desde la perspectiva analítica de la gobernanza regional como marco para conocer la injerencia de dicho fenómeno en los procesos de negociación de reglas. El presente artículo busca contribuir al análisis de la situación del derecho al aborto en América Latina y el Caribe a partir de dicho marco y sobre la base de una metodología cualitativa. Se examinan los aportes de las articulaciones transnacionales de activistas en defensa del aborto y los documentos oficiales de organismos internacionales, con una perspectiva novedosa que combina los estudios de la gobernanza global y los enfoques feministas críticos de las relaciones internacionales. Con el objetivo de señalar algunas pistas respecto a los desafíos pendientes, además de destacar los importantes avances logrados, se concluye que es significativo el lugar que ocupan en los procesos de negociación multilateral los movimientos y articulaciones feministas transnacionales que luchan por ampliar derechos.

ABSTRACT Introduction: The ureteral access sheath (UAS) is a medical device that enables repeated entrance into the ureter and collecting system during retrograde intrarenal surgery (RIRS). Its impact on stone-free rates, ureteral injuries, operative time, and postoperative complications remains controversial. Therefore, we performed a systematic review and meta-analysis comparing RIRS with versus without UAS for urolithiasis management. Purpose: To compare outcomes from retrograde intrarenal surgery (RIRS) for stone extraction with or without ureteral access sheath (UAS); evaluating stone-free rate (SFR), ureteral injuries, operative time, and postoperative complications. Materials and Methods: We systematically searched PubMed, Embase, and Cochrane Library in June 2024 for randomized controlled trials (RCTs) evaluating the efficacy and safety outcomes of UAS use in RIRS for urolithiasis treatment. Articles published between 2014 and 2024 were included. Pooled risk ratios (RRs) and mean differences (MDs) were calculated for binary and continuous outcomes, respectively. Results: Five RCTs comprising 466 procedures were included. Of these, 246 (52.7%) utilized UAS. The follow-up ranged from 1 week to 1 month. UAS reduced the incidence of postoperative fever (RR 0.49; 95% confidence interval [CI] 0.29–0.84; p=0.009), and postoperative infection (RR 0.50; 95% CI 0.30–0.83; p=0.008). There were no significant differences between groups in terms of SFR (RR 1.05; 95% CI 0.99–1.11; p=0.10), ureteral injuries (RR 1.29; 95% CI 0.95–1.75; p=0.11), operative time (MD 3.56 minutes; 95% CI −4.15 to 11.27 minutes; p=0.36), or length of stay (MD 0.32 days; 95% CI −0.42 to 1.07 days; p=0.40). Conclusion: UAS leads to a lower rate of post-operative fever and infection. However, UAS did not significantly reduce or increase the SFR or the rate of ureteral injuries during RIRS for patients with urolithiasis. The use of UAS should be considered to decrease the risk of infectious complications, particularly in those who may be at higher risk for such complications.

Resumo: Introdução : A anemia é um distúrbio altamente prevalente. A anemia pré-operatória está associada a maior mortalidade, mais complicações, tempo prolongado de internação e maiores custos de saúde. A transfusão de glóbulos vermelhos (TGV) não melhora esses resultados. A Organização Mundial da Saúde recomenda a implementação de medidas de Gerenciamento de Sangue do Paciente (GSP), pois permitem melhorar esses resultados clínicos, reduzir TGV desnecessárias e economizar custos. Apesar da evidência contundente, a implementação dessas medidas ainda está aquém de ser efetivada. O objetivo deste trabalho é realizar uma análise da situação para conscientizar sobre o problema e incentivar a implementação dessas medidas. Metodologia: Foi realizado um estudo observacional, longitudinal, retrospectivo de coorte histórica, unicêntrico. Foram incluídos todos os pacientes submetidos a cirurgias de coordenação de 01/01/2022 a 01/04/2022 no Hospital de Clínicas. Critérios de exclusão: ausência de hemograma nos três meses anteriores à cirurgia e recusa em participar do estudo. Resultados: Foram analisadas um total de 329 cirurgias. 52 a cada 100 procedimentos foram realizados em pacientes com anemia. Foi encontrada uma associação estatisticamente significativa entre a anemia pré-operatória e a recepção de TGR durante a internação. OR 11,746 (4,518 - 30,540). A anemia e as TGR prolongaram significativamente a internação hospitalar. Dias de internação em função da condição do paciente: Sem anemia: 10,1 ± 1,1 dias, com anemia: 27,2 ± 2,3 dias. Valor p < 0,001. Não transfundidos: 14,5 ± 1,3 dias, transfundidos: 41,8 ± 4,4 dias. Valor p < 0,001. Apenas 49 (28,6%) dos 171 pacientes com anemia tinham metabolismo do ferro antes da cirurgia. Dos 140 pacientes com Hb < 12 mg/dL submetidos a cirurgias com sangramento não insignificante, 4 receberam tratamento específico para otimizar a Hb. Foram administradas um total de 185 unidades de glóbulos vermelhos (UGV) durante a internação. 49 em pacientes instáveis (intraoperatório ou hemorragia aguda) e 136 em pacientes estáveis. Da análise desses últimos, 42,5% dos pacientes receberam 3 ou mais UGV. A hemoglobina pré-transfusional média foi de 7,0 ± 0,1. Foi encontrada uma associação estatisticamente significativa entre receber UGV e falecer durante a internação. OR 17,182 (3,360 - 87,872). Conclusões: Foi realizado uma análise da situação na qual foi observada uma elevada prevalência de anemia pré-operatória, um estudo e tratamento escasso da anemia antes das cirurgias e uma quantidade excessiva de UGV recebidas por alguns pacientes. Este trabalho estabelece a necessidade de implementar programas de Gerenciamento de Sangue do Paciente para reduzir a prevalência de anemia pré-operatória e melhorar nossas práticas transfusionais. Além disso, estabelece um quadro comparativo para avaliar o progresso dessas medidas e aponta possíveis indicadores para avaliar os benefícios de sua implementação.

Abstract: Introduction: Anemia is a highly prevalent disorder. Preoperative anemia is associated with higher mortality, more complications, longer hospital stays, and higher healthcare costs. Red blood cell transfusion (RBC) does not improve these outcomes. The World Health Organization recommends implementing Patient Blood Management (PBM) programmes, as they can improve these clinical outcomes, reduce unnecessary RBC transfusions, and save costs. Despite compelling evidence, the implementation of these measures has yet to be effectively achieved. The objective of this study is to conduct a situational analysis to raise awareness about this issue and encourage the implementation of these measures. Methodology: An observational, longitudinal, retrospective cohort study was conducted at a single center. All patients undergoing elective surgery from 01/01/2022 to 01/04/2022 at the Hospital de Clínicas were included. Exclusion criteria: absence of a complete blood count in the three months prior to surgery and refusal to participate in the study. Results: A total of 329 surgeries were analyzed. 52 out of 100 procedures were performed on patients with anemia. A statistically significant association was found between preoperative anemia and receiving RBC transfusion during hospitalization. OR 11.746 (4.518 - 30.540). Anemia and RBC transfusions significantly prolonged hospital stay. Length of hospitalization based on patient condition: No anemia: 10.1 ± 1.1 days, with anemia: 27.2 ± 2.3 days. Value of p < 0.001. Non-transfused: 14.5 ± 1.3 days, transfused: 41.8 ± 4.4 days. Value of p < 0.001. Only 49 (28.6%) of the 171 patients with anemia had iron metabolism assessed before surgery. Among the 140 patients with Hb < 12 g/dL undergoing surgeries with non-insignificant bleeding, only 4 received specific treatment to optimize Hb. A total of 185 units of red blood cells (RBC) were administered during hospitalization. 49 to unstable patients (intraoperative or acute hemorrhage) and 136 to stable patients. From the analysis of the latter group, 42.5% of the patients received 3 or more RBC units. The average pre-transfusion hemoglobin was 7.0 ± 0.1. A statistically significant association was found between receiving RBC units and dying during hospitalization. OR 17.182 (3.360 - 87.872). Conclusiones: A situational analysis was conducted, revealing a high prevalence of preoperative anemia, scarce study and treatment of anemia before surgeries, and an excessive amount of blood transfusions received by some patients. This work establishes the need to implement Patient Blood Management programs to reduce the prevalence of preoperative anemia and improve our transfusion practices. It also sets a comparative framework to evaluate the progress of these measures and indicates possible indicators to assess the benefits of their implementation.

SUMMARY: Simple hepatic cysts of the liver (SHCL) are incidentally detected in the liver, and may be solitary or multiple. There is sufficient evidence supporting the role of laparoscopic surgery in the treatment of these lesions. The aim of this study was to report the outcomes of laparoscopic treatment in patients with BSHCs in terms of postoperative complications (POC). Case series.All patients who underwent laparoscopic surgery for BSLC at RedSalud Mayor Clinic between January 2013 and December 2023 were included. Preoperative assessment consisted of general examinations, determination of ELISA-IgE and IgG for hydatidosis, abdominal ultrasound or computed tomography. The outcome variable was the development of postoperative complications (POCs). Descriptive statistics were used. During the study period, 22 patients with BSLC were operated, resecting them a total of 34 cysts. The median age of the series was 59 years, and 81.8 % of patients were female. The median sonographic diameter of the lesions was 9 cm. Subtotal pericystectomy was performed in all of them, without using drainage. In 45.4 % of cases simultaneously cholecystectomy for coexistent cholelithiasis was performed. The median operative time was 52 minutes. No patients needed to be converted. The series does not register POC or mortality. The median hospital stay was 1 day. The histopathological study confirmed "biliary type cyst" in all cases. With a minimum follow-up of 6 months, no late postoperative complications or recurrence of the resected lesions have been observed. The treatment applied to this series of cases was associated with a short hospital stay and good short- and medium-term outcomes.

RESUMEN: Los quistes hepáticos benignos simples del hígado (QHBSH) se detectan de forma incidental, pudiendo ser únicos o múltiples. Existe suficiente evidencia que avala el rol de la cirugía laparoscópica en el tratamiento de estas lesiones. El objetivo de este estudio fue informar los resultados del tratamiento laparoscópico en pacientes con QHBSH en términos de complicaciones postoperatorias (CPO). Serie de casos. Se incluyeron todos los pacientes intervenidos quirúrgicamente vía laparoscópica por QHBSH en la Clínica RedSalud Mayor entre enero de 2013 y diciembre de 2023. El estudio preoperatorio consistió en exámenes generales, determinación de ELISA-IgE e IgG para hidatidosis, ecotomografía abdominal o tomografía computarizada. La variable resultado fue desarrollo de CPO. Se utilizó estadística descriptiva. En el período estudiado, se intervinieron 22 pacientes con QHBSH, resecándose en ellos, un total de 34 quistes. El 81,8 % de los casos eran de sexo femenino; y la mediana de edad de la serie fue de 59 años. La mediana del diámetro ecográfico de las lesiones fue de 9 cm. Se realizó periquistectomía subtotal en todos ellos, sin utilización de drenaje. En el 45,4 % de los casos se ejecutó de forma simultánea una colecistectomía por colelitiasis coexistente. La mediana del tiempo quirúrgico fue de 52 minutos. No fue necesario convertir a ningún paciente. La serie no registra CPO ni mortalidad. La mediana de estancia hospitalaria fue de 1 día. El estudio histopatológico confirmó “quiste de tipo biliar” en la totalidad de los casos. Con un seguimiento mínimo de 6 meses, no se ha evidenciado CPO tardía ni reaparición de las lesiones resecadas. El tratamiento aplicado a esta serie de casos se asoció a escasa estancia hospitalaria y buena evolución a corto y mediano plazo.

Resumen El presente es un estudio retrospectivo, observacional, cuantitativo y descriptivo. Se evaluó la utilidad de la proteína C reactiva (PCR), la procalcitonina (PCT) y la relación PCR/PCT como marcadores de riesgo de sepsis, sumados al aclaramiento a las 72 h, como pronóstico de mortalidad y permanencia en unidades de cuidados intensivos (UCI). Se incluyeron 23 pacientes. Se clasificaron según qSOFA y se elaboraron curvas ROC. Se obtuvo un área bajo la curva de 0,79 para PCT. El valor umbral de PCT>0,88 ng/mL predice riesgo de sepsis con 77,78% de sensibilidad y 83,33% de especificidad. Utilizando PCR<31,23 mg/dL se obtuvo como parámetros destacados un 88,89% de sensibilidad y 83,33% de valor predictivo negativo, sin diferencias significativas (Mann-Whitney p<0,05) entre los grupos de sobrevivientes y óbitos y estadía prolongada vs. no prolongada. Se postula PCR como screening y PCT como marcador de riesgo de sepsis.

Resumo Este é um estudo retrospectivo, observacional, quantitativo e descritivo. Foi avaliada a utilidade da proteína C reativa (PCR), da procalcitonina (PCT) e da relação PCR/PCT como marcadores de risco de sepse junto com o clareamento em 72 horas, como preditores de mortalidade e permanência em unidades de terapia intensiva (UTI). Vinte e três pacientes foram incluídos. Eles foram classificados de acordo com o qSOFA e foram elaboradas curvas ROC, destacando uma área sob a curva de 0,79 para PCT. O valor limite de PCT>0,88 ng/mL prediz o risco de sepse com sensibilidade de 77,78% e especificidade de 83,33%. Utilizando PCR>31,23 mg/dL, obtiveram-se como parâmetros em destaque 88,89% de sensibilidade e 83,33% de valor preditivo negativo. Não houve diferenças significativas (Mann-Whitney p<0,05) entre os grupos de sobreviventes e óbitos e permanência prolongada vs. não prolongada. A PCR é postulada como triagem e a PCT como marcador de risco de sepse.

Abstract This is a retrospective, observational, quantitative and descriptive study. The utility of C reactive protein (CRP), procalcitonin (PCT) and the CRP/PCT ratio as sepsis risk markers was evaluated and these, added to clearance at 72 hours, as predictors of mortality and permanence in intensive care units (ICU). Twenty-three patients were included. They were classified according to qSOFA, and ROC curves were prepared, highlighting an area under the curve of 0.79 for PCT. The threshold value of PCT>0.88 ng/mL predicts the of sepsis with 77.78% sensitivity and 83.33% specificity. Using CRP>31.23 mg/dL, 88.89% sensitivity and 83.33% negative predictive value were obtained as outstanding parameters. No significant differences (Mann-Whitney p<0.05) were found between survivors and dead and prolonged vs. non-prolonged stay groups. CRP is postulated for screening and PCT as a sepsis risk marker.

Abstract Introduction Despite the evidence against drain placement after thyroidectomy, there is a lack of consensus on drain use in patients with substernal goiter. Objective To assess the factors that increase the likelihood of drain placement and its impact on postoperative hematoma and other 30-day complications among adult patients undergoing thyroidectomy for substernal goiter. Methods A retrospective cohort study that used data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Adult patients (aged ≥ 18 years) who underwent elective thyroidectomy for substernal goiter from 2016 to 2020 were included. Cases with closed suction neck drains placed upon completion of surgery were included in the drain group, and the remaining cases formed the nondrain group. Results A total of 1,229 patients were included (46.5% with drain placement). The factors that increased the likelihood of drain placement included body mass index (BMI) ≥ 30 kg/m2, score between 3 and 5 on the American Society of Anesthesiologists (ASA) physical status classification, sternal split/transthoracic surgical approach, operative time ≥ 90 minutes, and surgery conducted by otolaryngologists. Patients with clean-contaminated or contaminated wound classifications were less likely to be submitted to drain placement. In addition, drain use had no impact on postoperative hematoma formation but was found to independently increase the risk of prolonged length of hospital stay. Conclusion Thyroidectomy without drain placement might be safe for substernal goiter. However, this decision should be individualized for each patient. Level Of Evidence: 3 30day day ACSNSQIP.

Abstract Introduction. Gastric cancer in Colombia is the second most common neoplasm in men and the fourth in women. In recent years, the benefits of the laparoscopic approach in gastric cancer against bleeding, postoperative recovery com and complications have been widely described, without affecting oncological results. Methods. Retrospective observational study of patients undergoing laparoscopic gastrectomy at the Clínica Universitaria Colombia over a period of ten years, between 2013 and 2023. Perioperative results were described in terms of hospital stay, operative bleeding, duration of the procedure, complications, causes of reintervention, and mortality in the first 30 days. Results. 418 patients were included, 58.9% men, with an average age of 60.88 years. An average surgical time of 228.7 minutes was documented, with a blood loss of 150 ml. The mean number of lymph nodes resected was 26.1 ± 11.4. The average hospital stay was 4 ± 4 days, and complications were recorded in 104 subjects, with an average rate of 24%, of which 29 (27.4%) obtained a Clavien-Dindo IIIB classification. Conclusions. Laparoscopic gastrectomy in a high-volume center and with experienced surgeons in Colombia has perioperative results similar to those reported in the world literature. Studies with greater strength of association are still required to establish recommendations on the routine use of this approach in advanced malignant pathology.

Resumen Introducción. El cáncer gástrico en Colombia es la segunda neoplasia más común en hombres y la cuarta en mujeres.

Métodos. Estudio observacional retrospectivo de pacientes llevados a gastrectomía laparoscópica en la Clínica Universitaria Colombia durante un período de diez años, entre 2013 y 2023. Se describieron los resultados perioperatorios en cuanto a estancia hospitalaria, sangrado operatorio, duración del procedimiento, complicaciones, causas de reintervención y mortalidad en los primeros 30 días. Resultados. Se incluyeron 418 pacientes, 58,9 % hombres, con una edad promedio de 60,8 años. Se documentó un tiempo quirúrgico promedio de 228,7 minutos, con un sangrado de 150 ml. La media de ganglios linfáticos resecados fue de 26,1 ± 11,4. La estancia hospitalaria en promedio fue de 4 ± 4 días, y se registraron complicaciones en 104 sujetos, con una tasa promedio de 24 %, de las cuales 29 (27,4 %) obtuvieron una clasificación Clavien-Dindo IIIB. Conclusiones. La gastrectomía por laparoscopia en un centro de alto volumen y con cirujanos experimentados en Colombia, tiene resultados perioperatorios similares a lo reportado en la literatura mundial. Aún se requiere de estudios de mayor fuerza de asociación para establecer recomendaciones sobre el uso rutinario de este abordaje en patología maligna avanzada.

Abstract Introduction. The objective of this study was to compare the short-term outcomes of laparoscopic gastrectomy in adults vs. older patients with locally advanced gastric cancer from a Western country cohort. Methods. Prospective cohort study in patients undergoing laparoscopic gastrectomy for locally advanced gastric cancer at the Hospital Universitario Erasmo Meoz, de Cúcuta, Colombia, between November 2014 and December 2018. Descriptive, group comparison and bivariate analysis was performed. Results. Of a total of 116 patients, 51 patients (44%) were 65 years or older and 63 patients (54%) were men. No statistically significant difference was found when comparing patients under 65 years of age with those 65 years of age or older. The median operating time was 240 minutes in both groups (p>0.05), the median macroscopic resection margins were 6 cm vs. 5 cm (p>0.05), the median number of lymph nodes dissected was 25 vs. 19 (p>0.05), the median number of positive lymph nodes was 4 vs. 3 (p>0.05), the median stay was 7 days in both groups (p>0.05). The overall rate of postoperative complications did not differ significantly between adults (7%) and older adults (11%) (p>0.05) and no significant differences were observed in the rates of minor (Clavien-Dindo grade II; 3-5% vs. 6-12%; p>0.05) and severe complications (Clavien-Dindo ≥ IIIa; 3-5% vs. 4-8%; p>0.05). Conclusions. No statistically differences were found in short-term outcomes between adult and older patients with locally advanced gastric cancer treated with laparoscopic gastrectomy. This technique is safe in the elderly.

RESUMEN Introducción. Los datos sobre la prevalencia de coinfecciones o sobreinfecciones fúngicas en pacientes con COVID-19 son limitados. Objetivo. Describir la prevalencia de coinfecciones o sobreinfecciones fúngicas en pacientes con COVID-19, así como los factores de riesgo y las características demográficas, clínicas y microbiológicas. Material y métodos. Se incluyeron pacientes con diagnóstico confirmado de COVID-19, hospitalizados en la unidad de cuidados intensivos y con infección fúngica confirmada entre marzo del 2020 y diciembre del 2021. Del expediente clínico se obtuvieron datos sobre edad, sexo, comorbilidades, días de estancia hospitalaria, resultados de laboratorio (ferritina) y microbiológicos, tratamiento contra COVID-19, terapia antifúngica y desenlace. Resultados. Once de 740 pacientes cumplieron con los criterios de inclusión. La tasa de coinfección fue del 0,3 % y la de sobreinfección fue del 1,2 %. La población más afectada fue la de hombres adultos. Las coinfecciones o sobreinfecciones diagnosticadas fueron candiduria y candidemia, causadas por Candida albicans, C. tropicalis, C. glabrata, C. lusitaniae y Kluyveromyces marxianus (C. kefyr). Además, se encontró una traqueobronquitis por Aspergillus fumigatus. Los antifúngicos más administrados fueron fluconazol y caspofungina. La letalidad en pacientes con coinfecciones fue del 50 % y con sobreinfecciones fúngicas, del 22 %. El tiempo de estancia intrahospitalaria fue de 11 a 65 días. Ocho de los pacientes requirieron asistencia respiratoria mecánica y seis recibieron corticoides. La principal comorbilidad fue diabetes mellitus (81,8 %). Conclusiones. La tasa de coinfecciones o sobreinfecciones por hongos en pacientes con COVID-19 fue baja, pero la letalidad de estas requiere, con urgencia, la realización de pruebas de rutina para detectar hongos en pacientes con COVID-19 grave para diagnosticar oportunamente infecciones fúngicas que puedan comprometer aún más la vida del paciente.

ABSTRACT Introduction. Data on the prevalence of fungal coinfections/superinfections in patients with COVID-19 are limited. Objective. To describe the prevalence of fungal coinfections/superinfections in patients with COVID-19, as well as risk factors and demographic, clinical, and microbiological characteristics. Material and methods. We included patients with a confirmed COVID-19 diagnosis and a confirmed fungal infection hospitalized in the ICU from March 2020 to December 2021. We collected data on age, sex, comorbidities, hospital length of stay (days), laboratory (ferritin) and microbiological results, treatment for COVID-19, antifungal therapy, and outcomes obtained from the clinical records. Results. Only 11 out of 740 patients met the inclusion criteria. The coinfection rate was 0.3% and the superinfection was 1.2%. The most affected population was male adults. The coinfections/superinfections diagnosed were candiduria and candidemia, caused by Candida albicans, C. tropicalis, C. glabrata, C. lusitaniae, and Kluyveromyces marxianus (C. kefyr). In addition, tracheobronchitis due to Aspergillus fumigatus was found. The most used antifungals were fluconazole and caspofungin. The lethality in patients with fungal coinfections was 50% and superinfections, 22%. The length of hospital stay was 11-65 days. Eight patients required mechanical ventilation and six received corticosteroids. The main comorbidity was diabetes mellitus (81.8%). Conclusions. The rate of fungal coinfections/superinfections in COVID-19 patients was low, but the lethality found urges for routine fungal screening in patients with severe COVID-19 to timely detect fungal infections that may further compromise the patient's life.

RESUMEN Introducción: la mayoría de las fistulas enterocutáneas se producen como complicación de una o varias cirugías previas. La mortalidad sigue siendo muy elevada. Su tratamiento supone un reto para el cirujano y gran uso de recursos humanos, económicos y prolongada estancia hospitalaria. Objetivo: determinar la experiencia del manejo de las fístulas enterocutáneas postoperatorias en el servicio de cirugía general del Hospital Nacional de Itauguá durante el periodo 2017-2022. Metodología: estudio observacional descriptivo retrospectivo de corte transversal, con muestreo no probabilístico. Solo hubo 30 casos con fichas completas, las cuales sometimos a procesamiento y análisis de las variables de interés. Resultados: de la muestra final 70 % fueron hombres, el promedio de edad fue de 49,6 años y de días de internación 28,6. Solo 5 pacientes consultaron por secreción fecaloide, los demás refirieron secreción seropurulenta por herida o cicatriz operatoria. Del total, 9 fueron de alto débito. El 100 % recibió antibioticoterapia; obitaron 4 de los 14 pacientes intervenidos quirúrgicamente con fin terapéutico. La técnica quirúrgica mayormente utilizada fue: laparotomía + liberación de adherencias e identificación de la fístula + resección intestinal + anastomosis. De los antecedentes la mayoría fueron postoperados de oclusión intestinal mecánica alta o peritonitis aguda de origen apendicular. Conclusión: debido a su alto impacto en la capacidad laboral y social las fístulas enterocutáneas representan patologías quirúrgicas muy complejas y relevantes con bajas tasas de curación definitiva. La mayoría se presentan como complicación de cirugías de urgencia; requiere intervención multidisciplinaria adaptada para cada caso en particular.

ABSTRACT Introduction: the occur enterocutaneous fistula as a complication of one or several previous surgeries. Mortality is still very high. Its treatment represents a challenge for the surgeon and great use of human and economic resources and a long hospital stay. Objective: to determine the experience in the management of postoperative enterocutaneous fistulae in the general surgery service of the Itauguá National Hospital during the period 2017-2022. Methodology: retrospective, cross-sectional, descriptive, observational study with non-probabilistic sampling. There were only 30 cases with complete records, which we subjected to processing and analysis of the variables of interest. Results: of the final sample, 70 % were men, the average age was 49,6 years and 28,6 days of hospitalization. Only 5 patients consulted due to fecaloid discharge, the rest reported seropurulent discharge from wound or surgical scar. Of the total, 9 were high debit. 100 % received antibiotic therapy, 4 of the 14 patients who underwent surgery as therapeutics, died. The most commonly used surgical technique was: laparotomy + release of adhesions and identification of the fistula + intestinal resection + anastomosis. Most of the antecedents were post-operated for high mechanical intestinal occlusion or acute peritonitis of appendiceal origin. Conclusion: due to their high impact on work and social capacity, enterocutaneous fistulas represent very complex and relevant surgical pathologies with low definitive cure rates. Most present as a complication in emergency surgeries; requires multidisciplinary intervention adapted to each particular case.

RESUMEN Antecedentes: En las últimas décadas ha habido un cambio considerable hacia un enfoque más conservador en el tratamiento del traumatismocerrado de abdomen, con énfasis en la preservación de la función de órganos; actualmente, el tratamiento no operatorio (TNO) se ha convertido en la técnica de manejo estándar en pacientes hemodinámicamente estables con lesiones de órgano sólido. Objetivo: Describir las variables clínicas asociadas a la tasa de éxito en una serie de pacientes con TNO de trauma abdominal cerrado con lesión de órganos sólidos. Material y métodos: Estudio retrospectivo, observacional, longitudinal, analítico entre enero de 2017 y diciembre de 2022, sobre pacientes admitidos con diagnóstico de traumatismo abdominal cerrado. Las variables evaluadas fueron: edad, sexo, estadía hospitalaria, complicaciones, requerimiento de transfusiones, tasa de éxito y mortalidad. Resultados: De 2590 pacientes ingresados por Guardia de Cirugía General, 24 pacientes se internaron con diagnóstico de traumatismo cerrado de abdomen. Fueron excluidos 15 pacientes por no cumplir con los criterios de inclusión. Los 9 pacientes seleccionados tuvieron un promedio de edad de 39 años (15-80) y 9 fueron varones. En el 36% presentaron lesiones esplénicas grados I-II, 27% presentó lesión renal grado II y el 18% restante con lesión hepática grado II. La tasa de éxito del tratamiento fue del 100% en nuestra serie sin evidenciar fallos en la terapéutica instaurada. Conclusión: Con los criterios empleados en TNO del traumatismo abdominal cerrado con lesión de órganos sólidos fue factible y permitió alcanzar una alta tasa de éxito, sin mortalidad.

ABSTRACT Background: In recent decades, there has been a significant shift toward a more conservative approach to the management of blunt abdominal trauma with an emphasis on preserving organ function; currently, non-operative management (NOM) has become the standard of care for hemodynamically stable patients with solid organ injury. Objective: The aim of this study was to determine the different clinical variables associated with the success rate of NOM of blunt abdominal trauma with involving solid organs. Material and methods: We conducted a retrospective, observational, longitudinal, and analytical study of patients admitted for blunt abdominal trauma between January 1, 2017, and December 1, 2022. The variables evaluated were age, sex, length of hospital stay, complications, transfusion requirements, success rate and mortality. Results: Between January 2017 and December 2022, of 2590 patients seen in the emergency department, 24 were admitted with a diagnosis of blunt abdominal trauma. Fifteen patients did not meet the inclusion criteria. The mean age of the 9 patients included was 39 years (15-80 years) and 6 were men. Thirty-six percent had grade I and II splenic lesions, 27% had grade II renal lesions, and 18% had grade II hepatic lesions. The success rate of our series was 100% and there were no failures. Conclusion: The variables analyzed allowed us to affirm that NOM of blunt abdominal trauma with solid organ injury was feasible and allowed us to achieve a high success rate, without deaths.

RESUMEN Antecedentes: La medición de la calidad en cirugía, a través de las intervenciones de mejora, favorece mejores resultados para los pacientes y menos costos institucionales. Los resultados de libro quirúrgico (RLq) y los de libro oncológico (RLo) son una forma organizada de medir la calidad de la actividad quirúrgica. Objetivo: Estimar el cumplimiento de los parámetros de los RLq y RLo en una serie de pacientes con cáncer de recto bajo operados con amputación abdominoperineal por un mismo equipo. Material y métodos: Se realizó un estudio observacional descriptivo a partir de la revisión retrospectiva de los parámetros de los RLq y RLo en pacientes sometidos a una amputación abdominoperineal por cáncer de recto, entre agosto de 2015 y marzo de 2023, y se estimaron los porcentajes de cumplimiento en ambos libros. Resultados: Se incluyeron 26 pacientes cuyo promedio de edad fue de 52,07 años, y de ellos 18 (69,2%) fueron varones. En 25 casos (96 %) se realizó neoadyuvancia. Los RLq se cumplieron en 20 pacientes (76,9%), mientras que los RLo en 14 (53,8%), y ambos juntos en 13 (50%). Los ítems que más se presentaron para no llegar al 100% de cualquiera de los resultados fueron las complicaciones y el número de ganglios resecados igual a 12 o mayor, y, en menor medida, la resección R0, los días de estadía y la readmisión. Conclusión: Se lograron RLq y RLo adecuados en el 50% de los pacientes con amputaciones abdominoperineales. El análisis permite conocer dónde debemos actuar para mejorar la calidad de nuestros resultados.

ABSTRACT Background: Measuring quality in surgery through improvement interventions favors better patient outcomes and lower institutional costs. Textbook surgical outcome (TSO) and textbook oncologic outcome (TOO) are an organized way to measure the quality of surgical activity. Objective: The aim of the present study was to evaluate the proportion of patients with low rectal cancer who underwent abdominoperineal amputation by the same surgical team and achieved the TSO and TOO. Material and methods: We conducted a descriptive observational study based on the retrospective review of TSO and TOO parameters in patients undergoing abdominoperineal amputation for rectal cancer, between August 2015 and March 2023. The percentage of patients who achieved the TSO and TOO was estimated. Results: A total of 26 patients were included; mean age was 52.07 years and 18 (69.2%) were men and 25 patients (96%) received neoadjuvant therapy. The TSO was achieved in 20 patients (76.9%); 14 patients (53.8%) achieved the TOO and 13 patients (59%) achieved both textbook outcomes. The presence of complications and < 12 lymph nodes resected were the most common reasons for not achieving 100% of both textbook outcomes; other items were R0 resection, length of hospital stay and readmission. Conclusion: Fifty percent of patients with abdominoperineal amputations achieved an adequate TSO and TOO. The analysis allows us to understand where we must take action in order to improve the quality of our results.
