Construction of Detenial Sigmoid Neobladder after Laparoscopic Radical Cystectomy:Report of 71 Cases / 中国微创外科杂志

ABSTRACT

Objective To report our experience on construction of detenial sigmoid neobladder after laparoscopic radical cystectomy in 71 cases.Methods From August 2002 to May 2006,a total of 71 patients with invasive bladder carcinoma underwent construction of detenial sigmoid neobladder after laparoscopic radical cystectomy in our hospital.After the bladder was excised by laparoscopy,a 5-to 7-cm incision was made on the abdomen to remove the resected tissues,and then a 15-to 20-cm sigmoid colon was resected,the two colic bands opposite to the mesentery and the circular muscle and seromuscular layers between them were removed to construct a detenial sigmoid neobladder.Afterwards,the neobladder was anastomosed with the posterior urethra.Laparoscopic anastomosis was performed in 26 of the cases.Results The operation time was 240-390 min totally in the 71 cases.Laparoscopic radical cystectomy was finished in 80-270 min(mean,180 min),and the open surgery was completed in 160-240 min(mean 140 min).Oral intake was started at day 4-8 postoperation,ureteral stents were removed at week 3-4,and urethral catheter was removed at week 4.Three months after the operation,the mean intra-bladder pressure was 22.0 cm H2O(17-38 cm H2O),average bladder reservoir was 340 ml(200-410 ml),volume of residual urine was less than 25 ml in all the cases(
