AIM: Self-expandable metallic stents (SEMS) have been used for palliation in patients with malignant gastroduodenal obstructions. We evaluated clinical outcomes after SEMS placement and identified prognostic factors of SEMS patency, including chemotherapy. METHODS: A review of records of 85 patients with unresectable gastric or pancreatic cancer who underwent endoscopic SEMS insertion for gastroduodenal obstructions at Seoul National University Bundang Hospital. RESULTS: From August 2003 to October 2009, 85 patients with gastroduodenal obstruction were managed with endoscopic SEMS placement. Technical success was achieved in 82 patients (96%) and clinical success in 68 patients (80%). Of 49 patients who had clinical success, 19 underwent chemotherapy (chemoTx group), and 30 patients did not (non-chemoTx group). Cumulative SEMS patency in the 49 patients who achieved clinical success were 84, 54 and 41% at 2, 3 and 6 months, respectively. By univariate and multivariate analysis, there was no statistical difference in the SEMS patency between the two groups (cumulative SEMS patency rate: 95 vs 73% at 2 months, 15 vs 63% at 3 months, 40 vs 42% at 6 months, respectively, P < 0.793). CONCLUSION: Chemotherapy does not improve SEMS patency in patients with malignant gastroduodenal obstruction caused by unresectable gastric or pancreatic cancer.
