摘要

Background/Aims: Gastric outlet obstruction (GOO) is frequently caused by tumor. Recently, endoscopic implantation of self-expanding metallic stents (SEMS) has been introduced as an improved palliative treatment for GOO. This study aims to study the effect of SEMS placement on nutrient intake in patients with GOO and correlate different SEMS positions with postoperative clinical outcomes. Methodology: Fifty six non-operable patients with GOO were enrolled. Obstruction of the duodenum (n=23) or gastric outlet (n=33) were commonly found. Either Wallstent Enteral Stents, WallFlex Enteral Duodenal or partially covered Ultraflex esophageal stents were placed under endoscopic and fluoro-scopic guidance. The Gastric Outlet Obstruction Score (GOOSS) was used as the main outcome measurement. Results: The procedure was technically feasible in 100% of patients and gave satisfactory clinical results in 98.2% (55/56). The patients had a median survival time of 97.5 days (range 9-380). Median stent patency was 72 days with a range of 8 to 267 days. The average GOOSS, measuring oral intake, was significantly improved, regardless of obstruction site (p<0.05). We also found that the site of SEMS placement did not affect the clinical outcome. Conclusions: Palliation with SEMS is a safe and effective method for restoring gastric intake in patients with malignant GOO.
