title: [The clinical outcomes of endoscopic stent placement for patients with malignant gastric outlet obstruction - a comparison with gastrojejunostomy].
abstract: Owing to its less invasiveness, endoscopic stent placement is a potential treatment option for gastric cancer patients with gastric outlet obstruction( GOO). We compared the clinical outcomes of stent placement with gastrojejunostomy( GJ) bypass in terms of postoperative oral intake status, duration of oral intake, and overall survival. Thirty-eight patients who had unresectable gastric cancer with GOO were enrolled in this study. The stent placement group was divided into 2 subgroups: group P comprising 9 patients who received palliative treatment; and group A comprising 12 patients who received aggressive chemotherapy. Stent placement was performed for almost all the patients who had massive peritoneal metastasis and poor performance status. Improvement in oral intake was achieved in 19( 90.5%) of 21 patients after stent placement. Moreover, oral intake improved significantly in patients who underwent chemotherapy after stent placement. The median duration of oral intake and median overall survival was shorter in group P (1.8 and 2.8 months, respectively) and group A (3.2 and 4.8 months, respectively) than in group GJ( 11.8 and 12.7 months, respectively). In conclusion, endoscopic stent placement is effective in improving the oral intake status; however, it may be insufficient to improve the duration of oral intake. Thus, further studies are needed to clarify the clinical benefit of stent placement.
