The Comparison between Laparoscopic Wedge Resection and Open Wedge Resection for Gastric Gastrointestinal Stromal Tumors / 대한내시경복강경외과학회지

ABSTRACT

PURPOSE: A laparoscopic wedge resection is increasingly being used for gastrointestinal stromal tumors of the stomach. The aim of this study is to evaluate the safety and the feasibility of laparoscopic wedge resection compared to conventional open wedge resection. METHODS: Fifty-six patients who underwent laparoscopic wedge resection (LW group, n=32) or open wedge resection (OW group, n=24) for gastric submucosal tumor, between January 2005 and December 2007, were enrolled in this retrospective study. RESULTS: here were no significant differences in the patients' clinicopathological datas between the two groups. Although there were no significant difference in the operation time and the postoperative morbidity, the time to the first oral intake (1.2+/-1.5 vs. 1.5+/-0.6 days, p=0.015), the duration of hospital stay (3.4+/-0.7 vs. 5.5+/-0.8 days, p<0.001), and the number of analgesic use (2.2+/-0.9 vs. 4.0+/-1.2 times, p<0.001) were shorter or lower in the LW group than in the OW group. Among the LW group, three patients with endophytic growth pattern underwent intraoperative gastroduodenoscopy to identify the precise location of the tumor. CONCLUSION: Laparoscopic wedge resection is a safe and feasible treatment option for gastrointestinal stromal tumors. In addition, appropriate approach should be utilized according to the size, the location, and the growth pattern of the tumor.
