Abstract
The patient was a 47-year-old man who underwent reconstruction of the urinarybladder following low anterior resection and subtotal cystectomy for rectosigmoid cancer in May, 1990. The tumor was firmly adhering to the ileum nd the bladder. It could be resected en bloc with a part of the ileum and the urinary bladder wall, preserving the bladder neck. The histopathological findings showed that the tumor was well differentiated adenocarcinoma with se, n1, ly1, v0, ow (-), aw (-) and ew (-). Reconstruction of the bladder was performed by ileocecal cystoplasty, accompanied by anastomosis of the cecum to the bladder neck and the ileum to the ureters by the submucosal tunnel procedure, and it led to voluntary urination. The volume of the reconstructed bladder is 260 ml, the residual urine volume is 0 ml and he urinates 4 or 5 times a day at present, 6 years after the operation. Hydronephrosis, urinary tract infection, incontinence in the daytime, and recurrence have not occurred. Cases of total cystectomy preserving voiding function for invasion of colorectal cancer to the bladder have rarely been reported, but we believe this procedure is of great benefit for improving the quality of life of the patients after pelvic exenteration.
