Greater curvature gastroplasty. Follow-up at 34 months.

This retrospective study analyzes the results of 198 consecutive greater curvature gastroplasties performed in 23 male and 175 female patients with morbid obesity. The gastroplasty consisted of the creation of a 30-50 cm3 proximal gastric pouch by a double application of the TA-90 stapler, modified by removing three staples near the pin and trimming the cartridge to prevent crushing of the stomach at the outlet. The outlet was calibrated to a diameter of 1 cm and reinforced with a polypropylene seromuscular suture. No deaths occurred; postoperative complications included 32 superficial wound infections (16.2%), 24 incisional hernias (12.0%), 15 staple-line disruptions (7.6%), seven gastric outlet obstructions (3.5%), five subphrenic abscesses (2.5%), three perforations (1.5%), one splenic infarction, and one enterocutaneous fistula. One hundred sixty-one (81%) patients have been followed for a mean of 34 months (range 24 to 56 months); their mean weight loss is 36.4 per cent +/- 32.9 per cent of excess body weight. Only 45.5 per cent of these patients can be considered to have had satisfactory weight loss. Because this is not as effective as other forms of surgical therapy, the authors do not recommend greater curvature gastroplasty for the treatment of morbid obesity.
