Gastric neobladders: surgical outcomes of 91 cases using different techniques
ABSTRACT Introduction: We report on the surgical results of a series of 91 patients who received gastric neobladders as urinary diversion after radical cystectomies performed for the treatment of muscle-invasive bladder cancers. Materials and Methods: We report on a retrospective case series of 91 patients who received gastric neobladders as urinary diversion after radical cystectomies performed for the treatment of muscle-invasive bladder cancers. Different techniques of gastric neobladders were employed from 1988 to 2013 at a university hospital in the South of Brazil. Results: Initial outcomes utilizing Leong (Antral) and Nguyen-Mitchell (Wedge) technique were unsatisfactory, yielding high pressure, low capacity reservoirs. Further developments of these techniques, with the detubularized gastric neobladder and the “spherical” gastric neobladders resulted in low pressure, high capacity reservoirs, with better surgical and urodynamic outcomes. Complication and perioperative mortality rates of our series of gastric neobladders were significantly higher than historical results of techniques using ileum or colon. Conclusions: Stomach is an exceptional option for the creation of neobladders after radical cystectomies, but due to the increased complication rates it should be reserved for specific situations (e.g., renal insufficiency, previous pelvic/abdominal radiotherapy, short bowel syndromes).
