Is the Resected Gastric Volume Effective in the Complication of Laparoscopic Sleeve Gastrectomy?

Background: To determine the relationship between the resected gastric volume (RGV) and the results of laparoscopic sleeve gastrectomy (LSG). Methods: The study included 333 patients with LSG. Patients were divided into 4 groups according to RGV: 600 to 999 cm(3)as Group 1, 1000 to 1499 cm(3)as Group 2, 1500 to 1999 cm(3)as Group 3, and >= 2000 cm(3)consists the Group 4. Prospectively collected data at first month, sixth month, and at first year were retrospectively reviewed. The percentage of the reduction in body mass index and the excess weight loss and remission of comorbid diseases were recorded. Results: Preoperative demographic data were similar within groups. No statistically significant difference was observed between the groups in terms of the changes in excess weight loss. The major complication rates were highest in Group 4 and the difference between the groups was statistically significant (P=0.012). Conclusions: The results of this study showed that different RGV do not affect the results of LSG, furthermore in patients with RGV >= 2000 cm(3), surgeons should be careful for major complications.
