    BackgroundDuodenal obstruction is uncommon in patients with pancreatic cancer. However, the obstruction rate is increasing as a result of advancements in chemotherapy and target therapy. This study aimed to investigate the effect of self-expandable metal stent placement on outcomes of patients with duodenal obstruction secondary to pancreatic carcinoma.MethodsTwenty-nine consecutive inoperable patients with pancreatic cancer and gastric outlet obstruction who received metallic stent placement in our hospital between September 2009 and October 2017 were enrolled for analysis.ResultsFifteen male patients and 14 female patients receiving stent placement with a median age of 68 years (range, 50-85 years) were included. The technical and clinical success rates of the procedure were 100% and 89.7%, respectively. The Gastric Outlet Obstruction Scoring System scores were significantly improved at day 1 (1.14 ± 0.51) and days 7 (2.21 ± 0.9) after the implantation compared to those prior to the procedure (0.38 ± 0.49) (p < 0.001). Aspiration pneumonia and bleeding developed in 1 patient (3.4%) after the procedure. Stent dysfunction developed in 6 of 29 patients (20.6%). The median stent patency time was 109 days (range, 10-314 days). The median survival time was 114 days (range, 15-323 days). Post-stent chemotherapy predicted better survival (hazard ratio: 0.2, 95% confidence interval: 0.08-0.51, p = 0.001).ConclusionMetallic stent placement is an effective treatment for patients with inoperable pancreatic cancer leading to gastric outlet obstruction. Chemotherapy may be considered following stent placement.Copyright © 2019. Published by Elsevier B.V.
