ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

ABSTRACT Purpose Hartmann’s procedure is the resection of the rectosigmoid colon with an end colostomy formation and closure of the anorectal stump (1). Its reversal has a morbidity rate up to 58% (2, 3) with an incidence of fistulae formation of 4.08% (1). Herein, we present a robotic-assisted repair of a complex fistula that occurred as complication of Hartmann’s reversal when the stapler was introduced inadvertently through the vaginal canal. Patient and methods Eighty-three-year-old female with past medical history of hysterectomy and ischemic colitis that required colectomy and colostomy placement in December 2020. In March 2022, the patient underwent a colostomy takedown, after which she reported fecaluria, urine leakage per vagina, and recurrent urinary tract infections. Cystoscopy and vaginoscopy revealed a large colovesical fistula, a staple in the bladder trigone, and several staples in the anterior vaginal wall. Robotically, extensive adhesiolysis was performed, the sigmoid was separated from the bladder, and the intact rectal stump was dissected free. The staple from the bladder trigone was removed. Bladder was closed in two layers with 3-0 V-Loc. Colorectal anastomosis was not feasible due to the short length of both ends. Therefore, a permanent colostomy was placed. Results Operative time was 454min., and estimated blood loss was 100cc. Discharged on postoperative day 4 with a JP drain and a 20Fr Foley catheter. Drain, and Foley were removed on postoperative days 9 and 23, respectively. No postoperative complications were reported. Conclusion Robotic-assisted repair represents an effective approach for the management of colovesical fistulae after Hartmann’s reversal.

Objective To describe a novel technique of repairing the VVF using the transperitoneal-transvaginal approach. Materials and Methods From June 2011 to October 2013, four patients with symptoms of urine leakage in the vagina underwent robotic repair of VVF with the transperitoneal-transvaginal approach. Cystoscopy revealed the fistula opening on the bladder. A ureteral stent was placed through the fistulous tract. After trocar placement, the omental flap was prepared and mobilized robotically. The vagina was identified and incised. The fistulous tract was excised. Cystorrhaphy was performed in two layers in an interrupted fashion. The vaginal opening was closed with running stitches. The omentum was interposed and anchored between the bladder and vagina. Finally, the ureteral catheters were removed in case they have been placed, and an 18 Fr urethral catheter was removed on the 14th postoperative day. Results The mean age was 46 years (range: 41 to 52 years). The mean fistula diameter was 1.5 cm (range 0.3 to 2 cm). The mean operative time was 117.5 min (range: 100 to 150 min). The estimated blood loss was 100 mL (range: 50 to 150 mL). The mean hospital stay was 1.75 days (range: 1 to 3 days). The mean Foley catheter duration was 15.75 days (range: 10 to 25 days). There was no evidence of recurrence in any of the cases. Conclusions The robot-assisted laparoscopic transperitoneal transvaginal approach for VVF is a feasible procedure when the fistula tract is identified by first intentionally opening the vagina, thereby minimizing the bladder incision and with low morbidity.

Laparoendoscopic single site surgery (LESS) and natural orifice transluminal endoscopic surgery (NOTES) represent novel approaches in urological surgery. To perform a review of the literature in order describe the current status of LESS and NOTES in Urology. References for this manuscript were obtained by performing a review of the available literature in PubMed from 01-01-02 to 15-05-09. Search terms included single port, single site, NOTES, LESS and single incision. A total of 412 manuscripts were initially identified. Out of these, 64 manuscripts were selected based in their urological content. The manuscript features subheadings for experimental and clinical studies, as NOTES-LESS is a new surgical technique and its future evolution will probably rely in initial verified feasibility. A subheading for reviews presents information regarding common language and consensus for the techniques. The issue of complications published in clinical series and the future needs of NOTES-LESS, are also presented.

Objective: To create a simple, inexpensive, and reproducible model that would provide a new training option for performing urethrovesical anastomosis during laparoscopic radical prostatectomy. Material and methods: Design and experimentation were carried out in 2008. Materials employed included a laparoscopic training box, video camera, monitor, needle holder, sutures, and non-eviscerated chickens weighing more than 2 kilograms. The model was prepared with a new vision of a structure similar to the human pelvis. To create the anastomosis, we used the gizzard (bladder neck) and the rectum (urethra). Once the model was placed in the box, the anastomosis was performed in very similar anatomical conditions to those in real procedures. The anastomosis quality was assessed by means of an impermeability test and transanal endoscopy. Results: The operating field is very similar to the human pelvis. Tissues with a quality, texture, and diameter resembling those of the urethra (rectum) and the bladder neck (gizzard) offer the possibility of practicing anastomosis and anterior racket. Conclusions: The model for urethrovesical anastomosis using the chicken gizzard and rectum is simple, easy, available, inexpensive and reproducible. The anatomy of the chicken and the characteristics of its tissues allow for training under conditions very similar to those present in human cases.

Objetivo: Crear un modelo animal simple, económico y reproducible que presente una nueva opción de entrenamiento para la realización de la anastomosis vesicouretral durante la prostatectomía radical laparoscópica. Material y métodos: La creación y la experimentación se llevaron a cabo durante 2008. Se utilizaron diferentes materiales: caja de entrenamiento laparoscópico, cámara de vídeo, monitor, portaagujas, suturas y pollos no eviscerados de más de 2 kg de peso. El modelo fue elaborado con una nueva percepción de una estructura similar a la pelvis humana. Para la anastomosis se utilizó la molleja (cuello vesical) y el recto (uretra). Con el modelo en la caja, en condiciones anatómicas muy similares a los procedimientos reales, se realizó la experimentacion con la anastomosis. La calidad de la anastomosis se evaluó mediante una prueba de impermeabilidad y endoscopia transanal. Resultados: El área de trabajo fue muy similar a la de la pelvis humana. Tejidos de calidad, textura y diámetro similares a los de la uretra (recto) y el cuello vesical (molleja) ofrecen la posibilidad de practicar la anastomosis y la "raqueta anterior". Conclusiones: El modelo es simple, fácil, asequible, económico y reproducible. La anatomía del pollo, así como las características de sus tejidos, permite el entrenamiento en condiciones muy similares a las realizadas en casos humanos.

There is a very low rate of early prostate cancer detection in Latin America, since patients usually are diagnosed when the disease is in advanced stages. Sporadic prostate cancer screening campaigns do exist which allow us to diagnose this disease in earlier stages. Incidence and mortality rates differ widely from country to country, and they are probably underreported in our region since registers may be city-based instead of country-based.

La detección temprana del cáncer de próstata en Latinoamérica es muy baja, ya que los pacientes por lo general llegan con enfermedad avanzada; esporádicamente se realizan campañas de cribado del cáncer de próstata que nos permiten detectar esta enfermedad en estadios tempranos. Las tasas de incidencia y mortalidad varían de país en país; probablemente hay un subregistro en nuestra región, al no contar con registros que muestren la incidencia general por país, sino por ciudades.

Introduction: Acquired urachal anomalies are a rare pathology. Gold-standard treatment for this clinical situation remains the resection of the urachus in its entire tract with or without partial resection of the bladder. Our aim is to up-date authors´s experience in the minimally invasive surgical treatment of acquired urachal disease. Methods: From 2001 to 2007, 14 patients were operated for acquired urachal disease at our institution. A three portal technique previously described by the authors was employed. The diagnosis of acquired uracal disease was confirmed in all cases and the resection of the urachus in its entire tract performed in cephalocaudal direction onto the bladder. Operative and demographic data was prospectively collected and analysis retrospectively performed. Results: Mean operative time was 63 minutes (45,110), minimal blood loss, and no conversions to open surgery or perioperative complications were verified. The majority of the patients were discharged in the first 24 hours. At a follow-up of 22 months no recurrences of urachal pathology recurrences have been verified. Conclusions: Laparoscopy plays a significant role in the management of symptomatic urachus anomalies. It allows objective confirmation of clinical diagnosis and adequate resection of the urachus in a safe and efficient fashion, while providing the well-known advantages of minimally acces surgery. Preoperative evaluation work-up has minimal impact of therapeutical decision.

Introducción: Las anomalías uracales son una patología poco frecuente, el tratamiento aceptado consiste en la resección del uraco en todo su trayecto con o sin resección parcial de la vejiga. Nuestro objetivo es actualizar nuestra experiencia en el tratamiento de anomalías sintomáticas del uraco mediante cirugía de mínimo acceso. Pacientes y Métodos: Entre los años 2001 y 2007 se operaron 14 pacientes con anomalías adquiridas sintomáticas del uraco en nuestra institución. Se utilizó una técnica de tres portales previamente descrita por los autores, mediante la cual se realiza abordaje de la cavidad abdominal, confirmación del diagnóstico clínico inicial y resección del uraco en todo su trayecto en sentido cráneo caudal hasta la vejiga. Los datos demográficos y operatorios fueron recolectados de manera prospectiva y el análisis se realizó retrospectivamente. Resultados: El tiempo quirúrgico promedio fue de 63 minutos (45, 110) con sangrado mínimo, sin casos de conversión y sin complicaciones asociadas a la técnica. La gran mayoría de los pacientes egresó durante las primeras 24 horas. En un tiempo promedio de seguimiento de 22 meses no se han reportado recurrencias de la patología uracal. Conclusión: La laparoscopia juega un importante papel en el manejo de las anomalías sintomáticas del uraco, ya que permite confirmar el diagnóstico clínico y realizar la resección del uraco de manera segura y eficaz, aportando las ya conocidas ventajas de la cirugía de mínimo acceso. Los estudios de evaluación preoperatoria son de poca utilidad en la confirmación de esta patología.

Objetive: We present our initial experience in laparo-endoscopic single site (LESS) surgery, through multichannel port, articulated instruments and standard instruments adapted others adapted for the procedures. Materials and methods: Between February and October 2008, 28 LESS surgical procedures with multi-port were performed (Transumbilical simple prostatectomy (PSTU) and transvesical (PSTV), simple nephrectomy (NS), Enterocystoplasty augmentation (ECA) and simple hysterectomy (HS)). The clinical data were collected prospectively and analyzed retrospectively. Was used access device Multichannel (R-Port). The procedures were performed for a single surgeon (RS). The surgical technique was the same route used by conventional laparoscopic. Results: Twenty-eight surgeries were performed: PSTU (01), PSTV (20), NS (01), ECA (01), HS (05). The incision was performed umbilical or infraumbilical. Only one case (nephrectomy) needed it placement of an additional trocar. The average age by procedure was PSTU and PSTV, 67 and 68 year-old (57-89 y) respectively; NS 12 year-old; RCT 20 year-old; HS 46.4 year-old (41 - 54 y). The operative time was: PSTU 120 minutes, PSTV 91 minutes (45-210 min); NS 120 minutes; RCT 300 minutes; HS 112 minutes(90-160 min). The operative bleeding was PSTU and PSTV 200 cc. and 337 cc (50-1500 cc) respectively; NS 100cc; EAC 100 cc; HS 118 cc (100-160 cc). The complication was haematury in two cases of PSTV, both patients required exploration postoperative endoscopic with satisfactory evolution. Conclusions: LESS is a feasible and reproducible surgical option in uro-gynecologic surgical treatment. Further studies, experience and follow-up will provide an objective assessment of the technique.

Objetivo: Presentar nuestra experiencia inicial en LESS Surgery (Laparo-Endoscopic Single Site Surgery/Cirugía laparo-endoscópica por acceso único), mediante uso de dispositivo multicanal, instrumentos estándar, articulables y otros adaptados para la consecución de los procedimientos. Materiales y métodos: Entre febrero y septiembre del 2008 se realizaron 28 procedimientos quirúrgicos LESS con puerto multicanal: prostatectomía simple transumbilical (PSTU) y transvesical (PSTV), nefrectomía simple (NS), enterocistoplastia de aumento (ECA) e histerectomía simple (HS). Los datos clínicos fueron recopilados de manera prospectiva y analizados retrospectivamente. Se utilizó dispositivo de acceso multicanal (R-Port). Los procedimientos fueron realizados en un centro por un solo cirujano (RS). La técnica quirúrgica empleada correspondió a la misma utilizada por vía laparoscópica convencional. Resultados: Se realizaron 28 intervenciones quirúrgicas: PSTU(01), PSTV(20), NS(01), ECA(01), HS(05). La incisión de acceso fue realizada a nivel umbilical o infraumbilical. Solo un caso (nefrectomía) ameritó uso de trocar adicional de 2 mm. La edad media en años por procedimiento fue: PSTU, 67; PSTV, 68 (57-89); NS, 12; ECA, 20; HS, 46.4 (41-54). El tiempo quirúrgico medio en minutos fue: PSTU, 120; PSTV, 91 (45-210); NS, 120; ECA, 300; HS, 112 (90-160). El sangrado operatorio fue: PSTU, 200cc; PSTV, 337 cc (50-1500); NS, 100cc; EAC, 100cc; HS, 118cc. (100-160). La complicación observada fue hematuria profusa en dos casos de PSTV, ambos pacientes requirieron exploración postoperatoria con evolución satisfactoria. Conclusiones: LESS es una alternativa factible y reproducible en patología uroginecológica de resolución quirúrgica. Mayores estudios, experiencias y seguimiento permitirán la evaluación objetiva de esta técnica.
