Background. The mechanisms of weight loss after Roux-en-Y gastric bypass include stomach-restriction and malabsorbtion. Although satiety is achieved with a small stomach-porch, satisfactory weight-loss achieved not in every patient. Aim of the study was to compare weight loss and satiety after standard and new method of gastric bypass.
Methods and materials. 34 patients (10 males and 24 females) were operated in our clinic for morbid obesity. In 21 patients (1st group) standard laparoscopic gastric bypass was performed. Modified gastric bypass was performed in 13 patients (2nd group). New method includes resection of fundus of the stomach and resection and removing of 80-100 cm of ileum. Mean age of patients in the 1st group was 40 years (29-64). In the 2nd group – 38 (30-56) years. Mean BMI in the 1st group was 46,5 kg/m² and in the 2nd – 58,6 kg/m² . 7 patients from the 1st group and 8 patients from the 2nd had diabetes mellitus type 2 (T2DM).
Results. There was no mortality and serious complications in both groups of patients. After 1-2 years the mean excess weight loss was 62,8% in the 1st group and 89,3 % in the 2nd group (p < 0,01). Mean BMI was 36,2 kg/m² in the 1st group and 29,8 kg/m² in the 2nd group. Full resolution of T2DM was in 4 of 7 patients of the 1st group and 8 patients of the 2nd group.
Conclusion. Our preliminary results show that modified method of gastric bypass is more effective for weight loss and resolution of T2DM.
