Abstract BACKGROUND/GOAL: Self-expandable metallic stents can be used to reestablish luminal continuity in patients with malignancy of the esophagus, gastric outlet, or colon who are at high risk for surgical intervention. Data regarding their complication profiles remain incomplete. Our aim was to evaluate the feasibility and complications of endoscopic stenting in esophageal, gastroduodenal, and colonic malignancies. STUDY: Between January 2003 and December 2005, 153 patients underwent 182 endoscopic procedures for insertion of 199 metallic stents in a single referral center. Complications were assessed retrospectively. RESULTS: The mean follow-up was 170 days. The mortality was 73.9\% (113 patients), 105 cases between 1 and 60 weeks after the procedure (median survival, 17 wk), but none directly related to the stent placement. One single stent was required in 115 (75\%) patients, and 37 (24.2\%) cases required an overlapping stent. The procedure was unsuccessful in only 1 case of colonic obstruction. Thirty-eight (26.6\%) patients developed 52 complications, of which 16 (9.4\%) procedure-related complications (perforation, 5; migration, 5; obstruction, 3; misplacement, 2; and hemorrhage, 1) and 36 (21.3\%) late complications (obstruction, 20; migration, 9; fistula, 6; and perforation, 1). Eight (5.6\%) patients experienced more than 1 complication. Five (3.5\%) cases required surgery (colon: 2 perforations, 1 fistula, and 1 obstruction; esophagus: 1 perforation). No significant difference on the complication rates was found for any site in which a metallic stent was inserted. CONCLUSIONS: Endoscopic stenting for palliation of digestive cancer, despite a reasonable complication rate, is feasible in most patients. Most dysfunctions are not life-threatening and can be managed endoscopically. This article was published in J Clin Gastroenterol and referenced in Journal of Gastrointestinal & Digestive System
