Abstract

|
|
Background : The use of self-expandable metal stents (SEMS) is a safe and efficacious method for palliating malignant gastric outlet obstruction. However, few reports have assessed clinical outcome after the insertion of SEMS for malignant gastric outlet obstruction caused by stomach cancer. The aim of this study was to assess the usefulness of uncovered SEMS in patients with malignant gastric outlet obstruction caused by stomach cancer.
Methods : We evaluated 62 patients with gastric outlet obstruction caused by stomach cancer treated by the implantation of uncovered SEMS. A total of 62 patients (43 males, 19 females) were treated between August 2000 and March 2007. A scoring system was used to grade the ability to eat.
Results : Stent implantation was successful in 61 (98.4%) patients. Relief of obstructive symptoms was achieved in 49 (80.3%) patients. The mean survival duration was 143 days. The mean stent patency time was 103.5 days. An improvement in the ability to eat using the scoring system was statistically significant (p＜0.05).
Conclusion : Endoscopic placement of uncovered SEMS is a safe and effective treatment for the palliation of patients with inoperable malignant gastric outlet obstruction caused by stomach cancer. (Korean J Gastrointest Endosc 2008;36:57-63)
