OBJECTIVES: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. There is some controversy as to the effectiveness and feasibility of laparoscopic versus open resection of these tumors. We hypothesized that laparoscopic resection of gastric GISTs would offer better perioperative outcomes compared with the traditional open approach. METHODS: A retrospective review was conducted of all GISTs treated at a tertiary care urban teaching hospital between January 1999 and August 2008. The medical records were examined for demographic and clinicopathological features. RESULTS: Forty-six gastric GISTs were identified (17 treated laparoscopically and 29 treated via laparotomy). The median age of patients in these groups were comparable at 62 and 60, respectively. Body mass index of these patients were also similar at 28.2 kg/m for the laparoscopic and 29.9 kg/m for the open group. The average size of tumor was slightly smaller in the laparoscopic group at 4.27 cm versus the open group at 6.39 cm (NS). The estimated blood loss for the laparoscopic group was lower at 94 mL versus 169 mL (P = 0.059). Operative times for the 2 surgical approaches were not significantly different at 135 minutes for laparoscopic and 157.4 minutes for open. Laparoscopic resection yielded a significantly shorter length of stay compared with open at 2.68 versus 6.25 days (P < 0.001). CONCLUSIONS: Laparoscopic resection of gastric GISTs offers a decreased length of stay, a trend to decreased blood loss, and comparable oncologic outcomes indicating that a laparoscopic approach should be considered in all patients with gastric GISTs who do not have a contraindication to this approach.
