Gastrojejunostomy versus duodenal stent placement for gastric outlet obstruction in patients with unresectable pancreatic cancer

Background/Objective: Whether gastrojejunostomy (GJJ) or duodenal stent (DS) placement is preferable for treatment of gastric outlet obstruction (GOO) in patients with unresectable pancreatic cancer is unclear. We compared the usefulness of GJJ with that of DS placement in these patients. Methods: We retrospectively reviewed 66 consecutive patients with unresectable pancreatic cancer who underwent GJJ or DS placement for symptomatic GOO. Results: We analyzed 30 patients who underwent GJJ and 23 who underwent DS placement. Peritoneal metastasis was more common in the DS group. Median survival after the first intervention was similar in both groups. Although clinical success (maintaining a GOO Scoring System score >2 for more than 7 days) rate was significantly higher in the GJJ group (100% vs. 81%), clinical benefit (maintaining a score >2 for more than half of their survival after the first intervention) rate was similar between the GJJ and DS groups (66.7% vs. 69.7%), even among patients who survived for >= 90 days (73.3% vs. 75.0%). Further, the proportion of patients who could receive planned chemotherapy after the first intervention was higher and the time to administration of chemotherapy was significantly shorter in the DS group (9 vs. 32 days). Major complication rate was similar in both groups. Conclusions: These findings suggest that DS placement is as effective as GJJ for the treatment of GOO in patients with unresectable pancreatic cancer, even in those with a long life expectancy. DS placement might be more beneficial than GJJ in patients for whom chemotherapy is planned. (C) 2017 IAP and EPC. Published by Elsevier B.V. All rights reserved.
