Comparative analysis of results in laparoscopic radical cystectomy with extracorporeal and intracorporeal neobladder formation

The aim of the study is to compare the results and complications of muscle- invasive bladder cancer treatment using endovideo - surgical radical cycstectomy with orthotopic reservoir formation.Between 2013 and 2016 years, 49 patients with muscle -invasive bladder cancer underwent endovideo-surgical treatment with orthotopic reservoir formation. 38 patients underwent laparoscopic radical cystectomy with extracorporeal ileal conduit urinary diversioon [ men - 28 (74%), women - 10 (26%)], intracorporeal reservoir were perfomed in 11 cases [men - 8 (73%) and women - 3 (27%)]. The Modified Studer Ileal Neobladder (1st group) was performed in 32 ( 84%) cases, The Hautmann neobladder in 6 (16%) cases. During intracorporeal neobladder formation (2nd group) in all 11 cases Ileal Neobladder was created according to the methods of Karolinska Institutet, ( Sweden).In the first group 7 (18%) patients had early postoperative complications: in 1 case - Anastomosis failure, 3 patients - Defect of ureteroileal anastomosis and in other 3 cases - Adhesive intestinal obstruction. There was an incidence of late postoperative complications in 6 (15%) cases: 1 patient had exacerbation of chronic pyelonephritis, other 5 patients had stenosis of uretero-ileal anastomosis. Stenosis treatment methods were: in 3 cases - Laser endoureterotomy, and 2 patients underwent Intestinal plastic surgery of the ureter. In the second group 5 (45%) patients had early postoperative complications: in 2 cases - Defect of ureteroileal anastomosis, 2 patients had acute postoperative intestinal obstruction and in 1 case neobladder defect (multiple defects). In this group 4 (36%) patients had late postoperative complications: in 2 cases Stenosis of uretero-ileal anastomosis and other 2 - Active phase of chronic pyelonephritis.Due to medical technologies development and endovideo-surgical equipment improving, it became possible to perform high-technological operations, such as a laparoscopic radical cystectomy with neobladder formation using different parts of intestine. To imptove the results technical difficulties, postoperative complications and durations of operations were appraised, and we reccomend to perform laparoscopic radical cystectomy with extracorporeal neobladder formation.
