Abstract The authors aim to study Religiosity/Spirituality (R/S) and Quality of Life (QoL) in patients with Crohn's disease and their correlation with the disease phenotypes. Methods Prospective cross-sectional cohort study with 151 consecutive patients enrolled from March 2021 to October 2021 at the Colorectal IBD Outpatient of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP). Sociodemographic, Religiosity/Spirituality (Duke University Religion Index - Durel) questionnaires and QoL (Inflammatory Bowel Disease Questionnaire - Short IBDQ-S) were applied. When necessary, qualitative variables were evaluated using the chi-square or Fisher's exact test. The Mann-Whitney and Kruskall-Wallis tests were used to analyze quantitative variables and compare more than two groups, both non-parametric statistical techniques. Results The most frequent location was Ileocolonic followed by Ileal and colonic (41.1 %, 27.2 %, and 25.2 %); only 6.6 % of subjects had a perianal presentation. Inflammatory, stenosing, and penetrating behaviors showed 36.4 %, 19.1 %, and 44.4 % respectively. The majority of the population is Catholic, Evangelical, or Spiritualist (92.4 %). QoL score showed no significant difference in the phenotypes. The scores for DUREL domains were 61.4 % for organizational religiosity, 75 % for non-organizational religiosity, 98.6 %, 93.6 % and 89.3 % for intrinsic spirituality, with high results in all disease phenotypes. Conclusions The studied population presented homogeneous sociodemographic results and high religious and spiritual activity. R/S in a positive context were not associated with better QoL or phenotype. R/S is present in the patients’ lives and could be seen as an important tool for adherence to treatment and the professional relationship between doctor and patient. The homogeneity of the sample difficult for an appropriate evaluation, which leads us to suggest new studies with more heterogeneous groups.

Abstract Prognostic factors for local recurrence in patients with rectal cancer submitted to neoadjuvant chemoradiotherapy and total mesorectal excision. Background: The standard curative treatment for locally advanced rectal cancer of the middle and lower thirds is long-course chemoradiotherapy followed by total mesorectal excision. Purpose: To evaluate the prognostic factors associated with local recurrence in patients with rectal cancer submitted to neoadjuvant chemoradiotherapy and total mesorectal excision. Methods: Retrospective study including patients with rectal cancer T3–4N0M0 or T (any)N + M0 located within 10 cm from the anal border, or patients with T2N0M0 located within 5 cm, treated by long course chemoradio-therapy followed by total mesorectal excision with curative intent. Clinical, demographic, radiologic, surgical, and anatomopathological data were collected. Local recurrence was estimated using the Kaplan-Meier function, and risk was estimated according to each characteristic using univariate and multivariate analyses. Results: 270 patients were included, 57.8% male and mean age 61.7 (30‒88) years. At initial staging, 6.7% of patients were stage I, 21.5% stage II, and 71.8% stage III. Open surgery was performed in 65.2%, with sphincter preservation in 78.1%. Mortality within 30 postoperative days was 0.7%. After 49.4 (0.5‒86.1) months of median follow-up, overall and local recurrences were 26.3% and 5.9%. On multivariate analyses, local recurrence was associated with involvement of the mesorectal fascia on restaging MRI (HR = 9.11, p = 0.001) and with pathologic involvement of radial surgical margin (HR = 8.19, p < 0.001). Conclusion: Local recurrence of rectal cancer treated with long-course chemoradiation and total mesorectal excision is low and is associated with pathologic involvement of the radial surgical margin and can be predicted on restaging MRI.

Resumo Objetivo: Avaliar os valores máximo e médio de captação padronizada, o valor metabólico do tumor e a glicólise total da lesão do local do tumor primário, medidos no estudo de 18F-FDG-PET/CT realizado antes e depois da quimiorradioterapia neoadjuvante (nQRT) em pacientes com câncer de esôfago, como preditores de doença residual (DR). Materiais e Métodos: Os valores máximo e médio de captação padronizada e os parâmetros volumétricos (valor metabólico do tumor e glicólise total da lesão) da 18F-FDG-PET/CT realizada em 39 pacientes antes e após a nQRT para carcinoma de esôfago foram avaliados para RD. Usamos curvas receiver operating characteristic (ROC) para analisar o desempenho diagnóstico dos parâmetros 18F-FDG-PET/CT na definição de RD. O estudo anatomopatológico foi utilizado como padrão ouro. Resultados: Dezoito pacientes (46%) apresentaram DR após a nQRT. Áreas estatisticamente significativas sob a curva ROC para predizer DR foram obtidas para as quatro variáveis nos estudos realizados após a nQRT, com áreas sob a curva ROC semelhantes em torno de 0,72. Considerando a presença de captação visualmente detectável (captação maior que o background) no local da lesão primária após a nQRT como resultado positivo, teríamos uma sensibilidade de 94% e uma especificidade de 48% para detecção de DR. Conclusão: A 18F-FDG-PET/CT pode ser útil para detectar a presença de doença neoplásica residual no câncer de esôfago após a nQRT.

Abstract Objective: To evaluate the maximum and mean standardized uptake values, together with the metabolic tumor value and the total lesion glycolysis, at the primary tumor site, as determined by 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (18F-FDG-PET/CT), performed before and after neoadjuvant chemoradiotherapy (nCRT), as predictors of residual disease (RD) in patients with esophageal cancer. Materials and Methods: The standardized uptake values and the volumetric parameters (metabolic tumor value and total lesion glycolysis) were determined by 18F-FDG-PET/CT to identify RD in 39 patients before and after nCRT for esophageal carcinoma. We used receiver operating characteristic curves to analyze the diagnostic performance of 18F-FDG-PET/CT parameters in the definition of RD. The standard of reference was histopathological analysis of the surgical specimen. Results: Eighteen patients (46%) presented RD after nCRT. Statistically significant areas under the curve (approximately 0.72) for predicting RD were obtained for all four of the variables evaluated after nCRT. Considering the presence of visually detectable uptake (higher than the background level) at the primary tumor site after nCRT as a positive result, we achieved a sensitivity of 94% and a specificity of 48% for the detection of RD. Conclusion: The use of 18F-FDG-PET/CT can facilitate the detection of RD after nCRT in patients with esophageal cancer.

ABSTRACT BACKGROUND: Complete surgical resection is the main determining factor in the survival of advanced gastric cancer patients, but is not indicated in metastatic disease. The peritoneum is a common site of metastasis and preoperative imaging techniques still fail to detect it. AIM: The aim of this study was to evaluate the role of staging laparoscopy in the staging of advanced gastric cancer patients in a Western tertiary cancer center. METHODS: A total of 130 patients with gastric adenocarcinoma who underwent staging laparoscopy from 2009 to 2020 were evaluated from a prospective database. Clinicopathological characteristics were analyzed to identify factors associated with the presence of peritoneal metastasis and were also evaluated the accuracy and strength of agreement between computed tomography and staging laparoscopy in detecting peritoneal metastasis and the change in treatment strategy after the procedure. RESULTS: The peritoneal metastasis was identified in 66 (50.76%) patients. The sensitivity, specificity, and accuracy of computed tomography in detecting peritoneal metastasis were 51.5, 87.5, and 69.2%, respectively. According to the Kappa coefficient, the concordance between staging laparoscopy and computed tomography was 38.8%. In multivariate analysis, ascites (p=0.001) and suspected peritoneal metastasis on computed tomography (p=0.007) were statistically correlated with peritoneal metastasis. In 40 (30.8%) patients, staging and treatment plans changed after staging laparoscopy (32 patients avoided unnecessary laparotomy, and 8 patients, who were previously considered stage IVb by computed tomography, were referred to surgical treatment). CONCLUSION: The staging laparoscopy demonstrated an important role in the diagnosis of peritoneal metastasis, even with current advances in imaging techniques.

RESUMO RACIONAL: A ressecção cirúrgica é o principal fator determinante na sobrevida de pacientes com câncer gástrico, mas não é indicada na presença de doença metastática. O peritônio é local comum de metástase, porém os métodos de imagem ainda falham na sua detecção. OBJETIVO: Avaliar o papel da Laparoscopia Diagnóstica no estadiamento de pacientes com câncer gástrico avançado em um centro oncológico ocidental terciário. MÉTODOS: Foram avaliados 130 pacientes com adenocarcinoma gástrico submetidos a Laparoscopia Diagnóstica de 2009 a 2020, a partir de um banco de dados prospectivo. As características clínico-patológicas foram analisadas para identificar fatores associados à presença de metástase peritoneal. Foram também avaliadas a acurácia e concordância entre a tomografia computadorizada e a Laparoscopia Diagnóstica na detecção de metástase peritoneal e na mudança de conduta após a Laparoscopia Diagnóstica. RESULTADOS: As metástases peritoneais foram identificadas em 66 pacientes (50,76%). A sensibilidade, especificidade e acurácia da tomografia computadorizada na sua detecção foram de 51,5%, 87,5% e 69,2%, respectivamente. De acordo com o coeficiente Kappa, a concordância entre a Laparoscopia Diagnóstica e a tomografia computadorizada foi de 38,8%. Na análise multivariada, ascite (p=0,001) e suspeita de metástase peritoneal na tomografia computadorizada (p=0,007) foram estatisticamente correlacionadas com metástase peritoneal. Em 40 pacientes (30,8%), o estadiamento e as estratégias de tratamento mudaram após a Laparoscopia Diagóstica (32 pacientes evitaram laparotomia e 8 pacientes, anteriormente considerados estágio IVb, foram tratados cirurgicamente). CONCLUSÕES: A Laparoscopia Diagnóstica demonstrou um papel importante no diagnóstico de metástases peritoneais, mesmo com métodos de imagem avançados.

Abstract Objectives: To evaluate results of patients undergoing liver resection in a single center over the past two decades with a particular look at Colorectal Liver Metastasis (CRLM) and Hepatocellular Carcinoma (HCC). Method: Patients were divided into two eras, from 2000 to 2010 (Era 1) and 2011 to 2020 (Era 2). The most frequent diagnosis was CRLM and HCC, with 738 (52.4%) and 227 (16.1%) cases respectively. An evaluation of all liver resection cases and a subgroup analysis of both CRLM and HCC were performed. Preoperative and per operative variables and long-term outcomes were evaluated. Results: 1409 liver resections were performed. In Era 2 the authors observed higher BMI, more: minimally invasive surgeries, Pringle maneuvers, and minor liver resections; and less transfusion, less ICU necessity, and shorter length of hospital stay. Severe complications were observed in 14.7% of patients, and 90-day mortality was 4.2%. Morbidity and mortality between eras were not different. From 738 CRLM resections, in Era 2 there were significantly more patients submitted to neoadjuvant chemotherapy, bilateral metastases, and smaller sizes with significantly less transfusion, the necessity of ICU, and shorter length of hospital stay. More pedicle clamping, minimally invasive surgeries, and minor resections were also observed. From 227 HCC resections, in Era 2 significantly more minimally invasive surgeries, fewer transfusions, less necessity of ICU, and shorter length of hospital stay were observed. OS was not different between eras for CRLM and HCC. Conclusions: Surgical resection in a multidisciplinary environment remains the cornerstone for the curative treatment of primary and metastatic liver tumors.

ABSTRACT BACKGROUND: Solid pseudopapillary neoplasm of the pancreas is an uncommon pancreatic tumor, which is more frequent in young adult women. Familial adenomatous polyposis is a genetic condition associated with colorectal cancer that also increases the risk of developing other tumors as well. AIM: The aim of this study was to discuss the association of familial adenomatous polyposis with solid pseudopapillary neoplasm of the pancreas, which is very rare. METHODS: We report two cases of patients with familial adenomatous polyposis who developed solid pseudopapillary neoplasm of the pancreas of the pancreas and were submitted to laparoscopic pancreatic resections with splenic preservation (one male and one female). RESULTS: ß-catenin and Wnt signaling pathways have been found to play an important role in the tumorigenesis of solid pseudopapillary neoplasm of the pancreas, and their constitutive activation due to adenomatous polyposis coli gene inactivation in familial adenomatous polyposis may explain the relationship between familial adenomatous polyposis and solid pseudopapillary neoplasm of the pancreas. CONCLUSION: Colonic resection must be prioritized, and a minimally invasive approach is preferred to minimize the risk of developing desmoid tumor. Pancreatic resection usually does not require extensive lymphadenectomy for solid pseudopapillary neoplasm of the pancreas, and splenic preservation is feasible.

RESUMO RACIONAL: A neoplasia sólida pseudopapilífera do pâncreas é um tumor pancreático incomum, mais frequente em mulheres jovens. A polipose adenomatosa familiar, por sua vez, é uma condição genética associada a câncer colorretal e que também aumenta o risco de desenvolvimento de outros tumores. OBJETIVOS: Discutir a associação entre polipose adenomatosa familiar e neoplasia sólida pseudopapilífera, que é bastante rara. MÉTODOS: Reportamos dois casos de pacientes com polipose adenomatosa familiar, um homem e uma mulher, que desenvolveram neoplasia sólida pseudopapilífera do pâncreas e foram submetidos a ressecção laparoscópica com preservação esplênica. RESULTADOS: As vias de sinalização da ß-catenina e Wnt tem um papel importante na tumorigênese da neoplasia sólida pseudopapilífera, e sua ativação constitutiva devido a inativação do gene adenomatous polyposis coli na polipose adenomatosa familiar pode explicar a relação entre polipose adenomatosa familiar e neoplasia sólida pseudopapilífera. CONCLUSÕES: A ressecção do cólon deve ser priorizada, com preferência pela abordagem minimamente invasiva para minimizar o risco de desenvolvimento de tumor desmoide. A ressecção pancreática geralmente não requer linfadenectomia extensa para neoplasia sólida pseudopapilífera, portanto, a preservação esplênica é factível.

RESUMO - RACIONAL: Pelo menos 12 linfonodos (LNs) devem ser examinados após a ressecção cirúrgica do câncer de cólon. Como é difícil encontrar LNs pequenos, fixadores de clareadores de gordura foram propostos, mas não há consenso sobre a melhor opção. OBJETIVO: Verificar se a solução de Carnoy (SC) aumenta o número de LNs obtidos em espécimes de câncer de cólon esquerdo. MÉTODOS: Ensaio prospectivo randomizado (clinictrials.gov: NCT02629315) com 60 pacientes com adenocarcinoma de cólon esquerdo submetidos à retossigmoidectomia. As amostras foram randomizadas para fixação com SC ou formalina tamponada neutra a 10% (NBF). Após a dissecção, a gordura pericólica do grupo NBF foi imersa em SC e redissecada (Revisão). O endpoint primário foi o número total de LNs recuperados. RESULTADOS: O número médio de LNs foi de 36,6 e 26,8 para os grupos CS e NBF, respectivamente (p=0,004). O número de casos com <12 LNs foi 0 (CS) e 3 (NBF, p=0,237). A duração da dissecção foi semelhante. LNs foram recuperados em todos os casos durante a revisão (média de 19, intervalo: 4-37), representando quase 40% dos LNs deste braço do estudo. Após a revisão, nenhum caso no braço NBF permaneceu com <12 LNs. Dois pacientes tiveram LNs metastáticos encontrados durante a revisão (não ocorreu upstaging). CONCLUSÃO: Em comparação com NBF, a SC aumenta a contagem de LNs em espécimes de câncer de cólon. Após a análise patológica convencional, a fixação da gordura pericólica com SC e a realização de uma segunda dissecção aumentaram o número de LNs.

ABSTRACT - BACKGROUND: At least 12 lymph nodes (LNs) should be examined following surgical resection of colon cancer. As it is difficult to find small LNs, fat clearing fixatives have been proposed, but there is no consensus about the best option. AIM: The objective of this study was to verify if Carnoy’s solution (CS) increases the LN count in left colon cancer specimens. METHODS: A prospective randomized trial (clinicaltrials.gov registration: NCT02629315) with 60 patients with left colon adenocarcinoma who underwent rectosigmoidectomy. Specimens were randomized for fixation with CS or 10% neutral buffered formalin (NBF). After dissection, the pericolic fat from the NBF group was immersed in CS and re-dissected (Revision). The primary endpoint was the total number of LNs retrieved. RESULTS: Mean LN count was 36.6 and 26.8 for CS and NBF groups, respectively (p=0.004). The number of cases with <12 LNs was 0 (CS) and 3 (NBF, p=0.237). The duration of dissection was similar. LNs were retrieved in all cases during the revision (mean: 19, range: 4-37), accounting for nearly 40% of the LNs of this arm of the study. After the revision, no case was found in the NBF arm with <12 LNs. Two patients had metastatic LNs during the revision (no upstaging occurred). CONCLUSION: Compared to NBF, CS increases LN count in colon cancer specimens. After conventional pathologic analysis, fixing the pericolic fat with CS and performing a second dissection substantially increased the number of LNs.

RESUMO CONTEXTO: As doenças inflamatórias intestinais (DII), que englobam a doença de Crohn e a colite ulcerativa, são doenças inflamatórias crônicas do trato gastrointestinal que frequentemente se manifestam em adolescentes e adultos jovens (AAJ). As DII são caracterizadas por episódios de doença ativa intercalados com períodos de remissão, e sua atividade se correlaciona inversamente com a qualidade de vida relacionada à saúde (QVRS). OBJETIVO: Este estudo teve como objetivo determinar se AAJ em remissão ou com baixa atividade de DII exibiria QVRS semelhante à de indivíduos saudáveis pareados por idade, e se fatores demográficos da doença poderiam afetar a QVRS usando um instrumento de medidas de desfecho relatadas pelo paciente. MÉTODOS: Este estudo envolveu apenas AAJ com DII, com baixa atividade. Esta pesquisa incluiu cinco clínicas multidisciplinares de dois Hospitais Universitários: Divisões de Gastroenterologia Pediátrica, Gastroenterologia, Coloproctologia, Reumatologia Pediátrica e Adolescentes, São Paulo, Brasil. Um total de 59 AAJ com DII (13-25 anos de idade) e 60 AAJ controle saudáveis (13-25 anos de idade) responderam os questionários Pediatric Quality of Life Inventory 4.0 e 36-Item Short-Form Health Survey e as escalas visuais de dor. Dados demográficos, manifestações extra intestinais, tratamentos e desfechos da doença de Crohn e a colite ulcerativa foram avaliados. RESULTADOS: AAJ com DII e os controles saudáveis foram grupos semelhantes com relação à média de idade (18,63 [13,14-25,80] vs 20,5 [13,68-25,84] anos, P=0,598), quanto à proporção de pacientes do sexo feminino (42% vs 38%, P=0,654), e quanto à porcentagem da classe socioeconômica brasileira média elevada/ média (94% vs 97%, P=0,596). Os escores escola/trabalho foram significativamente mais baixos nos AAJ com DII do que nos controles saudáveis (70 [10-100] vs 75 [5-100], P=0,037). O escore ‘percepção geral de saúde’ foi significativamente mais baixo nos AAJ com DII do que no agrupamento controle saudável (50 [10-80] vs 0 [25-90], P=0,0002). As escalas de avaliação visual de dor foram semelhantes entre os dois grupos (2 [0-10] vs 3 [0-9], P=0,214). Nenhuma associação entre QVRS e parâmetros clínicos e demográficos foi identificada entre os pacientes com DII. CONCLUSÃO: AAJ com baixa atividade das DII relataram baixa QVRS nos domínios da escola/trabalho e percepção geral da saúde, o que destaca um critério de incapacidade nesta vulnerável população.

ABSTRACT BACKGROUND: Inflammatory bowel diseases (IBD), comprising Crohn’s disease and ulcerative colitis, are chronic inflammatory diseases of the gastrointestinal tract that often have their onset among adolescents and young adults (AYA). IBD are characterized by episodes of active disease interspersed with periods of remission, and its activity is inversely correlated with health-related quality of life (HRQL). OBJECTIVE: This study aimed to determine whether AYA in remission or with low IBD activity would exhibit HRQL similar to that of age-matched healthy individuals, and whether demographic and disease factors could affect HRQL using a ‘patient-reported outcome’ instrument. METHODS: This study enrolled only AYA with IBD, with low activity. This research included five multidisciplinary clinics of two academic hospitals: Paediatric Gastroenterology, Gastroenterology, Coloproctology, Paediatric Rheumatology and Adolescent divisions, São Paulo, Brazil. A total of 59 AYA with IBD (age, 13-25 years) and 60 healthy AYA (age, 13-25 years) completed the Pediatric Quality of Life Inventory 4.0 and 36-Item Short-Form Health Survey questionnaires and the visual analogue scale (VAS) for pain. Demographic data, extra-intestinal manifestations, treatment, and outcomes regarding CD and UC were evaluated. RESULTS: AYA with IBD and healthy controls were similar with respect to median ages (18.63 [13.14-25.80] years vs 20.5 [13.68-25.84] years, P=0.598), proportion of female sex (42% vs 38%, P=0.654), and percentage of upper middle/middle Brazilian socioeconomic classes (94% vs 97%, P=0.596). The school/work score was significantly lower in AYA with IBD than in healthy controls (70 [10-100] vs 75 [5-100], P=0.037). The ‘general health-perception’ score was significantly lower in AYA with IBD than in healthy controls (50 [10-80] vs 0 [25-90], P=0.0002). The median VAS, FACES pain rating scale, and total VAS scores were similar between the two groups (2 [0-10] vs 3 [0-9], P=0.214). No association between HRQL and clinical and demographic parameters was identified among IBD patients. CONCLUSION: AYA with low IBD activity reported poor HRQL in school/work and general health perception domains, which highlights a disability criterion in this vulnerable population.

RESUMO Racional: O tratamento da doença hemorroidária pela técnica de THD (Transanal Hemorrhoidal Dearterialization) é minimamente invasivo e tem se mostrado seguro e eficiente. No entanto, dados sobre a recorrência e complicações (dor e tenesmo) no pós-operatório são muito variáveis. Objetivo: Avaliar se a desarterialização e mucopexia seletiva, sem o uso de Doppler, é suficiente para o controle de sintomas e se a morbidade pós-operatória é menor com esta técnica. Métodos: Vinte pacientes foram tratados com essa técnica e avaliados sobre controle de sintomas, morbidade pós-operatória e recorrência. Resultados: Controle do prolapso e sangramento foi observado em todos pacientes (n=20). Complicações pós-operatórias foram: tenesmo (n=2), trombose hemorroidária externa (n=2), retenção urinária (n=2). Após um seguimento médio de 13 meses, nenhuma recorrência foi detectada. Conclusões: O procedimento de desarterialização e mucopexias seletivas é seguro e eficiente em termos de controle do prolapso e sangramento. Esta técnica resulta em menor morbidade cirúrgica, uma vez que diminui o número de suturas no canal anal, resultando em menos dor e tenesmo pós-operatório. Para este procedimento o uso de ultrassom Doppler é desnecessário, o que diminui custos e o torna mais atrativo do ponto de vista econômico.

ABSTRACT Background: Transanal hemorrhoidal dearterialization (THD) is safe and effective minimally invasive treatment for hemorrhoidal disease, but reports regarding recurrence and postoperative complications (pain and tenesmus) vary significantly. Aim: To evaluate if selective dearterialization and mucopexy at the symptomatic hemorrhoid only, without Doppler guidance, achieves adequate control of the prolapse and bleeding and if postoperative morbidity is reduced with this technique. Methods: Twenty consecutive patients with grade II and III hemorrhoids were treated with this new approach and were evaluated for postoperative complications and recurrence. Results: Control of prolapse and bleeding was achieved in all patients (n=20). Postoperative complications were tenesmus (n=2), external hemorrhoidal thrombosis (n=2) and urinary retention (n=2). After a mean follow-up of 13 months no recurrences were diagnosed. Conclusion: Selective dearterialization and mucopexy is safe and achieves adequate control of prolapse and bleeding and, by minimizing sutures in the anal canal, postoperative morbidity is diminished. Doppler probe is unnecessary for this procedure, which makes it also more interesting from an economic perspective.

RESUMO Racional: Devido à falta de padrões normais de manometria anorretal no Brasil, os dados utilizados estão sujeitos a padrões de normalidade descritos em diferentes nacionalidades . Objetivo: Determinar os valores e a faixa da manometria anorretal de pessoas em idade produtiva, sem distúrbios do assoalho pélvico, comparando os parâmetros obtidos entre homens e mulheres. Métodos: Análise prospectiva de dados clínicos, como gênero, idade, raça, índice de massa corporal (IMC) e manometria anorretal, de voluntários de uma referência universitária brasileira em distúrbios do assoalho pélvico. Resultados: Quarenta pessoas foram incluídas, com idade média de 45,5 anos nos homens e 37,2 nas mulheres (p=0,43). De acordo com homens e mulheres, respectivamente em mmHg, as pressões de repouso foram semelhantes (78,28 vs. 63,51, p=0,40); pressões de contração (153,89 vs. 79,78, p=0,007) e pressão total de compressão (231,27 vs. 145,63, p=0,002). Os homens apresentaram valores significativamente maiores de contração esfincteriana, assim como o comprimento médio do canal anal funcional (2,85 cm nos homens vs. 2,45 cm nas mulheres, p=0,003). Conclusões: Os níveis normais de pressão esfincteriana no Brasil diferem dos utilizados até o momento como padrão normal da literatura. O gênero masculino apresenta maior tônus do esfíncter anal externo em relação ao feminino, além de maior extensão do canal anal funcional

ABSTRACT Background: Due to the lack of normal standards of anorectal manometry in Brazil, data used are subject to normality patterns described at different nationalities. Aim: To determine the values and range of the parameters evaluated at anorectal manometry in people, at productive age, without pelvic floor disorders comparing the parameters obtained between male and female. Methods: Prospective analysis of clinical data, such as gender, age, race, body mass index (BMI) and anorectal manometry, of volunteers from a Brazilian university reference in pelvic floor disorders. Results: Forty patients were included, with a mean age of 45.5 years in males and 37.2 females (p=0.43). According to male and female, respectively in mmHg, resting pressures were similar (78.28 vs. 63.51, p=0.40); squeeze pressures (153.89 vs. 79.78, p=0.007) and total squeeze pressures (231.27 vs. 145.63, p=0.002). Men presented significantly higher values of anorectal squeeze pressures, as well as the average length of the functional anal canal (2.85 cm in male vs. 2.45 cm in female, p=0.003). Conclusions: Normal sphincter pressure levels in Brazilians differ from those used until now as normal literature standards. Male gender has higher external anal sphincter tonus as compared to female, in addition a greater extension of the functional anal canal

OBJECTIVES: Since the outbreak of the novel coronavirus disease 2019 (COVID-19), all health services worldwide underwent profound changes, leading to the suspension of many elective surgeries. This study aimed to evaluate the safety of elective colorectal surgery during the pandemic. METHODS: This was a retrospective, cross-sectional, single-center study. Patients who underwent elective colorectal surgery during the COVID-19 pandemic between March 10 and September 9, 2020, were included. Patient data on sex, age, diagnosis, types of procedures, hospital stay, mortality, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) preoperative screening tests were recorded. RESULTS: A total of 103 colorectal surgical procedures were planned, and 99 were performed. Four surgeries were postponed due to positive preoperative screening for SARS-CoV-2. Surgical procedures were performed for colorectal cancer (n=90) and inflammatory bowel disease (n=9). Laparoscopy was the approach of choice for 43 patients (43.4%), 53 (53.5%) procedures were open, and 3 (3%) procedures were robotic. Five patients developed COVID-19 in the postoperative period, and three of them died in the intensive care unit (n=3/5, 60% mortality). Two other patients died due to surgical complications unrelated to COVID-19 (n=2/94, 2.1% mortality) (p<0.01). Hospital stay was longer in patients with SARS-CoV-2 infection than in those without (38.4 versushttps://doi.org/10.3 days, respectively, p<0.01). Of the 99 patients who received surgical care during the pandemic, 94 were safely discharged (95%). CONCLUSION: Our study demonstrated that elective colorectal surgical procedures may be safely performed during the pandemic; however, preoperative testing should be performed to reduce in-hospital infection rates, since the mortality rate due to SARS-CoV-2 in this setting is particularly high.

OBJECTIVE: The Coronavirus Disease 2019 (COVID-19) pandemic has been recognized as one of the most serious public health crises. This study aimed to evaluate the short-term impact of the pandemic on the surgical treatment of patients with gastric cancer (GC) in addition to their clinicopathological characteristics. We also verified adherence to the COVID-19 screening protocol adopted in the institution. METHODS: All patients with GC who underwent surgical treatment between 2015 and 2021 were retrospectively evaluated and divided into two groups according to the time period: control group (2015-2019) and COVID group (2020-2021). The institutional protocol recommends that patients referred for surgery undergo RT-PCR for severe acute respiratory syndrome coronavirus 2 infection. RESULTS: A total of 83 patients were classified into the COVID group and 535 into the control group. The number of surgical procedures performed in the control group was 107 (SD±23.8) per year. Diagnostic procedures (p=0.005), preoperative chemotherapy (p<0.001), and adenocarcinomas without Lauren's subtype (p=0.009) were more frequent in the COVID group than in the control group. No significant difference was observed in the pathological characteristics and surgical outcomes of curative GC between the two groups. Evaluation of protocol compliance showed that of 83 patients with GC in the COVID group, 19 (22.9%) were not tested for COVID-19 before surgery. Two patients tested positive for COVID-19 (one preoperative and one postoperative). CONCLUSION: A decrease in the average number of surgeries and a higher frequency of diagnostic procedures occurred during the pandemic than in the previous time period. Tumor/node/metastasis classification, morbidity rates, and mortality rates in patients with GC during the pandemic did not differ from those in the previous time period. Accordingly, GC surgical treatment with acceptable screening protocol compliance could be safely performed during the COVID-19 pandemic.
