title: Overcoming Wallstent malposition in the treatment of rectosigmoid obstruction.
abstract: 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.
