Palliation of malignant gastroduodenal obstruction with open surgical bypass or endoscopic stenting: clinical outcome and health economic evaluation.

摘要

Gastroduodenal outlet obstruction is a complication of advanced gastrointestinal malignant disease. In the past it was usually treated by an open surgical bypass procedure. During the last decade, endoscopic self-expandable stents (SEMS) have been used. The aim of this study was to compare these two palliative strategies concerning clinical outcome and health economy. A series of 36 patients with incurable malignant disease and gastroduodenal outlet obstruction syndrome were treated in a prospective study. According to the attending hospital and endoscopist on duty, 21 of the 36 patients were endoscopically treated with SEMS and 15 underwent an open surgical gastroenteroanastomosis. Health economic evaluation was based on the monetary charges for each patient associated with the procedure, postoperative care, and hospital stay. The hospital stay was 7.3 days for the stented group compared with 14.7 days for the open surgery group ( p > 0.05). The survivals were 76 and 99 days, respectively (NS). In thestented group all 15 patients (100%) alive after 1 month were able to eat or drink, and 11 (73%) of them tolerated solid food. In the surgical bypass group,9 out of 11 (81%) patients alive after 1 month could eat or drink, and 5 of them (45%) could eat solid food. The mean charges (U.S. dollars) during the hospital stay were Dollars 7215 for the stented group and Dollars 10,190 for the open surgery group ( p < 0.05). Palliation of the gastroduodenal obstruction in patients with malignant disease were at least as good, and the charges were lower for the endoscopic stenting procedure than for an open surgical bypass.
