title: [Laparoscopic repair of enterovesical fistula in patient affected by left megaureter].
abstract: BACKGROUND
  Enterovesical fistula (EVF) is an abnormal communication between the intestine and the bladder. We present the case of EVF secondary to diverticular disease in a male with congenital megaureter. A laparoscopic repair of the colon vesical fistula was performed with colon resection.
  
  
  METHODS
  With the patient in the Trendelenburg position -30° degrees on the right side, 5 trocars are positioned trans-peritoneally. The exploration of the abdominal cavity shows the sigmoid diverticular disease adhering tenaciously to the posterior wall of the bladder. The intestinal loops are medialized. The inferior mesenteric vein is isolated, clipped and divided. The mesosigma is isolated and the inferior mesenteric artery is closed 2 cm from its emergence from the aorta with EndoGIA™ 45 stapler. The left colon is isolated from its splenic flexure to the mesorectum. The peritoneum between the bladder and sigmoid colon at the site of the tenacious adhesions is incised. The left megaureter is isolated from the diverticular disease and the bladder is opened on the site of the fistula, to permit a wide resection of the fistula. The posterior wall of the bladder is then closed with double running sutures. Section of the rectum with EndoGIA™ 45 stapler. Extraction of 20 cm of sigma comprising diverticular disease by a 5 cm suprapubic laparotomy. The sigma is cut and the proximal head of the circular stapler is inserted and closed with a running suture. The left colon is put back in place into the peritoneal cavity. The laparotomy is closed and the surgery is reconverted into laparoscopy. A colorectal end-to-end anastomosis according to Knight Griffen is performed with ILS 29 circular stapler. The anastomosis is tested for leakage with hydropneumatic test: no evidence of spillage. A laminar drainage is placed close to the anastomosis and the incisions are closed.
  
  
  RESULTS
  The operative time was 240 minutes. There were no intra- or post-operative complications. The bladder catheter was removed on day 7 after cystography. The patient was discharged asymptomatic on the 8th post-operative day.
  
  
  CONCLUSIONS
  Laparoscopic treatment of enterovesical fistulas for benign disease is a safe and standardized procedure. It remains a difficult procedure with a conversion rate higher than laparoscopy for uncomplicated diverticulitis or malignancy. The procedure in a single session with intracorporeal bowel anastomosis is the standard.
