Transanal Minimally Invasive Surgery (TAMIS) to Treat Vesicorectal Fistula: A New Approach

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.

Laparoendoscopic single-site nephroureterectomy for morbid obese patients

Since the first laparoendoscopic single-site (LESS) surgery report in urology in 2007 (1) (Rane A e Cadeddu JA), the few reports of LESS extraperitoneal access in the literature were mainly described for less complex cases. The aim of this video is to demonstrate the feasibility of LESS extraperitoneal access in a morbid obese patient presenting a malignant tumor in the renal pelvis. The patient is positioned in 90-degree lateral decubitus. An incision is made below the abdominal skin crease on the left side of the patient and the anterior rectus fascia is vertically incised with manual dissection of the extra/retroperitoneal space. We use an Alexis® retractor to retract the skin maximizing the incision orifice. Three trocars (12, 10 and 5 mm) are inserted through a sigle-port. The pedicle was controlled “en bloc” with a vascular stapler and the bladder cuff treated by the conventional open approach through the same incision. Operative time was 126 minutes with minimal blood loss. The pathology reported high grade papillary urothelial carcinoma in the pelvis (pT3N0M0) and in the ureter (pTa). LESS extraperitoneal nephroureterectomy is feasible and safe, even in more complex cases. It is a good alternative for morbid obese patients and for patients with synchronous distal ureteral tumors for whom an open approach to the bladder cuff is proposed to avoid incisions in two compartments of the abdominal wall.

Expanded criteria for Video Endoscopic Inguinal Lymphadenectomy (VEIL) in penile cancer: palpable lymph nodes

Introduction Open inguinal lymphadenectomy is the gold standard for the treatment of inguinal metastasis in patients with penile cancer (PC). Recently the Video Endoscopic Inguinal Lymphadenectomy (VEIL) was proposed as an option to reduce the morbidity of the procedure in patients without palpable inguinal lymph nodes (PILN), however the oncological equivalency in patients with PILN remains poorly studied. The aims of this video are the demonstration of VEIL in patients with PILN and present the preliminary experience comparing patients with and without PILN. Materials and Methods The video illustrates the procedure performed in two cases that were previously underwent partial penectomy for PC with PILN. Data from the series of 15 patients (22 limbs operated) with PILN underwent VEIL were compared with our series of VEIL in 25 clinically N0 patients (35 limbs operated). Results The comparison between the groups with and without PILN found, respectively, these outcomes: age 52,45 × 53,2 years, operative time 126,8 × 95,5 minutes, hospital stay 5. × 3.1 days, drainage time 6.7 × 5.7 days, 9 resected lymph nodes on average in both groups, global complications 32% × 26%, cellulitis 4.5% × 0%, lymphocele 23% in both groups, skin necrosis 0% × 3%, myocutaneous necrosis 4.5% × 0%, pN+ 33% × 32%, cancer specific mortality 7% × 5% and mean follow-up 17.3 × 35.3 months. None of the variables presented p < 0.05. Conclusions VEIL is a safe complementary procedure for treatment of PC, even in patients with PILN. Oncological results in patients with PILN seem to be appropriate but are still very premature. Prospective multicenter studies with larger samples and long-term follow-up should be conducted to determine the oncological equivalence of VEIL compared with open surgery in patients with PILN. .

Associação entre o consumo de tabaco e a progressão do câncer superficial da bexiga / Amount of tobacco consumption is associated with superficial bladder cancer progression

Objective: To evaluate the association between smoking habits and outcome of patients with superficial bladder cancer. Methods: A retrospective study was performed evaluating 99 patients (67.0 ± 13.2 years, ranging from 31.4-93.4 years, 72.7% males and 27.3% females) treated at our institution with non muscle-invasive bladder cancer, between 1994 and 2000, with a mean follow-up of 49.3 months (range 4.0-177.9 months). Patients were divided according to smoking status, and the main measured outcome was progression to invasive disease. Additional cohort analysis was performed dividing patients according to previous tobacco exposure: smokers and non-smokers. Smokers were stratified into former smokers, early-quitters, late quitters and continued smokers. Results: Smoking habit was significantly more common in males (p = 0.03). Cancer also occurred at an earlier age among smokers (70.8 versus 64.8 years, p = 0.030). Tobacco consumption was present in 62.7% of the patients with bladder cancer. There was a significant higher progression rate to muscle-invasive disease in patients that had more than 60 pack-years of exposure (52.9 versus 26.2%, p = 0.037). These patients had a mean progression time of 59.3 months, whereas patients who had smoked less than 60 pack-years progressed after a mean time of 131.8 months. Conclusions: A direct association between the amount of tobacco consumed and disease progression is observed in patients with bladder cancer, as suggested by the present study. Tobacco consumption has a direct association with progression of superficial bladder cancer to invasive disease and also shortens the period of time for muscle invasion. Larger and prospective studies are still necessary to bring further definitive conclusions about reproducibility of our data and to better understand how smoking cessation affects progression of superficial bladder cancer.

Objetivo: Avaliar a relação entre os hábitos tabágicos e a evolução de pacientes com carcinoma urotelial de bexiga superficial. Métodos: Foi realizado um estudo retrospectivo com 99 pacientes (67,0 ± 13,2 anos, variando de 31,4-93,4 anos, 72,7% homens e 27,3% mulheres) tratados de carcinoma urotelial de bexiga não-invasivo entre 1994 e 2000, com seguimento médio de 49,3 meses (4,0-177,9 meses). Os pacientes foram divididos em tabagistas e não-tabagistas, e os tabagistas foram subestratificados entre ex-tabagistas, interruptores precoces, interruptores tardios e tabagistas persistentes. O principal desfecho avaliado foi a progressão para doença invasiva. Resultados: O tabagismo foi mais comum entre os homens (p = 0,03), sendo que 62,6% do total de pacientes avaliados eram tabagistas. O diagnóstico do câncer ocorreu em uma idade mais precoce entre os tabagistas (70,8 versus 64,8 anos, p = 0,03). Observou-se uma progressão significativamente maior para doença invasiva entre os pacientes com carga tabágica acima de 60 maços/ano (52,9 versus 26,2%, p = 0,037). Estes pacientes tiveram um tempo de progressão de 59,3 versus 131,8 meses para aqueles com menor carga tabágica. Conclusões: Há associação direta entre a carga tabágica e progressão do carcinoma urotelial de bexiga para doença músculo-invasiva em um curto intervalo de tempo. Estudos prospectivos e com maior número de pacientes são necessários para entender como a interrupção do tabagismo afeta a progressão do carcinoma superficial de bexiga.

Cálculo de vesícula seminal tratado por cirurgia videolaparoscópica: relato do primeiro caso brasileiro / Seminal vesicle stone treated by laparoscopic surgery: report ofthe first Brazilian case

A ocorrência de cálculo de vesícula seminal é uma entidade rara, compoucos relatos na literatura mundial, sendo ainda mais escassos artigossobre o tratamento videolaparoscópico. A importância do diagnósticoestá relacionada ao fato de o cálculo de vesícula seminal ser um fatorna gênese da prostatite e ter relação com dor perineal e na ejaculação,simulando quadro de prostatite sem infecção demonstrável. Relatamoso caso de um paciente de 36 anos com quadro de dor perineal epolaciúria persistente, apesar de tratamento clínico adequado. Atomografia e a ecografia transretal diagnosticaram cálculo de istmode vesícula seminal bilateral. A vesiculectomia seminal bilateral porlaparoscopia resultou em remissão da sintomatologia e controle dainfecção em seguimento de seis anos.
