Abstract. – Gastric outlet obstruction is either a late event in the natural history of bilio-pancreatic tumors or the result of recurrent gastric or pancreatic tumors. Self-expansible metal stents, inserted under endoscopic and fluoroscopic control, can be used for palliative treatment. The present study was aimed at evaluating both the feasibility and the results of stenting in patients with malignant gastric outlet obstruction; in addition, some technical suggestions are presented.
A total of 33 patients, who had a metal stent positioned, were retrospectively evaluated; 20 of them were women and 13 were men, aged from 45 to 94 years, with a mean age of 75 years. Twentyseven patients had a pancreatic adenocarcinoma, 4 had a stricture of a gastrojejunal anastomosis due to recurrent pancreatic tumor, 2 had a stricture of a gastrojejunal anastomosis secondary to gastric cancer surgery. No postoperatory complications were observed. Improvement in the quality of life was obtained in all patients. Following the stenting procedure, the median duration of hospitalization was 8 days (range: 6-20 days), and the mean survival rate was 12 weeks (range: 2-66 weeks).
Endoscopic stenting for the palliation of malignant gastric outlet obstruction is feasible and is well tolerated by most patients. In some cases a period of enteral nutrition had to be necessarily carried out; nonetheless, the insertion of the stent improved the quality of life.
