RESUMEN
ABSTRACT Introduction: Video endoscopic inguinal lymphadenectomy - VEIL - has emerged as an alternative to reduce post-surgical complications (PSC) in patients with penile cancer submitted to inguinal lymphadenectomy (IL). In some series, these PSC are observed in more than 50% of patients. The objectives of the present study are to describe the initial experience of VEIL in a Hospital in Teresina, PI, Brazil, and to analyze PSC incidence. Material and Methods: Retrospective descriptive study of patients submitted to VEIL from March 2014 to November 2015. Data were collected regarding surgical time, bleeding, complications, lymph node number, conversion, global complications, drainage time, cellulitis, lymphocele, cutaneous necrosis, miocutaneous necrosis and hospitalization time. Results: 20 lower limbs of 11 patients were operated. Mean age was 51.4 (24-72) years. Mean surgical time was 85 (60-120) minutes. No patient showed intrasurgical complications, bleeding > 50 mL or conversion. Three surgeries evolved with lower limb edema, 2 with lymphoceles and one patient had cutaneous necrosis and another bulging of surgical wound. Mean time of hospitalization was 4 (2-11) days. A mean of 5.8 (1-12) lymph nodes were dissected in each surgery. Conclusion: VEIL is a safe and easy technique with lower incidence of PSC that can be reproduced in small centers.

ABSTRACT Introduction Penile cancer (PC) occurs less frequently in Europe and in the United States than in South America and parts of Africa. Lymph node (LN) involvement is the most important prognostic factor, and inguinal LN (ILN) dissection can be curative; however, ILN dissection has high morbidity. A nomogram was previously developed based on clinicopathological features of PC to predict ILN metastases. Our objective was to conduct an external validation of the previously developed nomogram based on our population. Materials and methods We included men with cN0 ILNs who underwent ILN dissection for penile carcinoma between 2000 and 2014. We performed external validation of the nomogram considering three different external validation methods: k-fold, leave-one-out, and bootstrap. We also analyzed prognostic variables. Performance was quantified in terms of calibration and discrimination (receiver operator characteristic curve). A logistic regression model for positive ILNs was developed based on clinicopathological features of PC. Results We analyzed 65 men who underwent ILN dissection (cN0). The mean age was 56.8 years. Of 65 men, 24 (36.9%) presented with positive LNs. A median 21 ILNs were removed. Considering the three different methods used, we concluded that the previously developed nomogram was not suitable for our sample. Conclusions In our study, the previously developed nomogram that was applied to our population had low accuracy and low precision for correctly identifying patients with PC who have positive ILNs.

ABSTRACT Purpose: Vesicorectal fistula is one of the most devastating postoperative complications after radical prostatectomy. Definitive treatment is difficult due to morbidity and recurrence. Despite many options, there is not an unanimous accepted approach. This article aimed to report a new minimally invasive approach as an option to reconstructive surgery. Materials and Methods: We report on Transanal Minimally Invasive Surgery (TAMIS) with miniLap devices for instrumentation in a 65 year old patient presenting with vesicorectal fistula after radical prostatectomy. We used Alexis® device for transanal access and 3, 5 and 11 mm triangulated ports for the procedure. The surgical steps were as follows: cystoscopy and implant of guide wire through fistula; patient at jack-knife position; transanal access; Identification of the fistula; dissection; vesical wall closure; injection of fibrin glue in defect; rectal wall closure. Results: The operative time was 240 minutes, with 120 minutes for reconstruction. No perioperative complications or conversion were observed. Hospital stay was two days and catheters were removed at four weeks. No recurrence was observed. Conclusions: This approach has low morbidity and is feasible. The main difficulties consisted in maintaining luminal dilation, instrumental manipulation and suturing.

Introduction Vesicovaginal fistula is a rare disease with great impact for the patients. Laparoscopic repair can be an interesting option in selected cases with goods results but few experience is reported.Objectives Detailed demonstration of our laparoscopic vesicovaginal fistula repair technique. Initial results for ten patients are provided Methods: We treated all cases by the same technique. The surgical steps were: Patient positioning in Lloyd-Davis; Cystoscopy and implant of guide wire on fistula and ureteral catheters (that was removed after procedure); Transperitoneal access and 4 or 5 ports in V or W shape; Opening the bladder wall; Dissection between bladder and vagina for tension free repair; Fistula resection; Vagina repair with Vicryl 3-0; Bladder repair with Vicryl 3-0; Peritoneum/omentum interposition; Positioning 20 Fr urethral catheter.Results Mean age was 50 years. Mean number of fistulas was 1,2. The most common etiology was gynecologic surgery (7). Mean operative time was 2,5 (1,8-3,2) hours. Mean blood loss was 150 (100-200)mL. Complication rate was 10% (one case of urinary infection treated conservatively). Mean hospital stay was 1,2 (1-2) days. Mean return to normal and activities was 20 (15-30) days. For nine patients mean sexual intercourse time was 3 (1-6) months. Success rate after 1 year was 90% (one case of recurrence in patient with previous radiotherapy). Mean follow-up was 36 (12-60) months.Conclusions Laparoscopic repair is feasible, reproducible and present all advantages of minimally invasive surgical procedure. Long term results are similar to conventional open approaches.

O objetivo do presente estudo é uma análise descritiva dos pacientes com câncer de pênis tratados em nossa instituição. Pacientes e métodos: Estudo transversal descritivo de 99 pacientes com câncer de pênis atendidos no Hospital São Marcos no período de 1998 a 2002. Analisaram-se as variáveis relacionadas à epidemiologia e ao tratamento do câncer de pênis. Resultados: A idade variou de 28 a 89 anos com média de 59,2 anos. Os estadiamentos mais freqüentes foram II, III e IV, respectivamente. O tratamento cirúrgico empregado foi a penectomia parcial em 45 casos e a penectomia total em 21 casos. Com um seguimento médio de 17,6 meses, 20,2 por cento dos pacientes estão vivos sem doença, 71 por cento estão vivos com doença e 68,7 por cento não retornaram para seguimento. Conclusão: O estadiamento mais freqüente foi do tipo II e o tratamento cirúrgico mais realizado foi a nectomia parcial
