In recent years, the use of transanal stenting of malignant colonic strictures for the palliation of obstructive symptoms has increased. Due to the rectosigmoid angle, stenting sigmoid tumors is more troublesome than rectal lesions, but the difficulty may be overcome by using a two-team approach. The radiologist assists the endoscopist with the use of fluoroscopy to ensure proper positioning of both the colonoscope and the stent. The most common complication is stent migration, but stent obstruction and colonic perforation may also occur. We treated a woman suffering from metastatic gastric cancer with peritoneal metastases by creating a 12-cm stricture in the sigmoid colon. Two adjoining Wallstents were required to bridge the obstruction. Following migration of the proximal stent, a third stent was introduced to bridge the previous two stents with satisfactory outcome.
BACKGROUND AND OBJECTIVES: We present the long-term functional results of a new technique for bladder substitution after cystectomy for bladder cancer in women. METHODS: Between 1991 and 1995, 10 women underwent radical cystectomy for bladder cancer with a new technique. We created a detubularized rectosigmoid neobladder associated with either a terminal colostomy or intrasphincteric perineal colostomy section (Heitz-Boyer-Hovelacque). We evaluated neobladder functioning over almost 5 years by means of urodynamic studies, ultrasound scans, urograms and pouchgrams, and renal function tests. RESULTS: Neobladder function was excellent in all patients, with good diurnal and nocturnal urinary continence, voiding patterns, and preservation of the upper urinary tract. CONCLUSIONS: This new technique, which is a modification of the standard rectal or rectosigmoid neobladder technique, is a valid alternative to the ortothopic neobladder in women, with good functional results.
