[An ileal neobladder-enteric fistula 10 years after a radical cystectomy with ileal neobladder construction].

: A 67-year-old male underwent a radical cystectomy and ileal neobladder construction in September 2002. He developed adhesive ileus postoperatively and underwent an intestine-ascending colon bypass operation with a side-to-side anastomosis in December of 2002. Subsequently, the patient developed ileus frequently, which improved with conservative management. In February 2013, he had fecaluria and was diagnosed with an ileal neobladder-enteric fistula based on computed tomography 2 hours after contrast medium injection. He underwent closure of the intestinal anal side of the anastomosis between the intestine and ascending colon. The fecaluria disappeared and he is making steady progress. An ileal neobladderenteric fistula as a long-term postoperative complication of ileal neobladder construction is extremely rare, with no other reports to our knowledge. Here, we discuss its cause, diagnosis and treatment, with reference to previous reports.
