PURPOSE: Sphincter-preserving operations performed with bladder-preserving surgery and a cystourethral anastomosis (CUA) do not require a urinary stoma, but leakage from the CUA may develop. The aim of this study was to evaluate the efficacy of performing an additional flap operation.
METHODS: The subjects were 39 patients who underwent bladder-preserving surgery for advanced rectal cancer involving the prostate, between 2001 and 2015.32 of whom had a CUA and one of whom had a neobladder. Five of these 32 patients underwent an ileal flap operation, 2 underwent an omental flap operation, and 3 underwent an operation using both flaps.
RESULTS: Leakage developed in 3 (30%) of the 10 patients who underwent additional flap operations, but in 14 (60.9%) of the 23 patients who did not undergo a flap operation. The mean periods of catheterization for the patients who suffered leakage were 31 weeks (8-108 weeks) in those without a flap and 16 weeks (8-20 weeks) in those with a flap. Four (33.3%) of the 12 patients with leakage after surgery without a flap had a period of urinary catheterization >30 weeks, and 2 (16.7%) had leakage of CTCAE grade 3. There were no cases of leakage after flap surgery.
CONCLUSION: An additional flap operation may decrease the risk of leakage from a CUA.
