Abstract

Roux-en-Y gastric bypass is a surgical technique widely used in the treatment of obesity. It is unclear, however, if the length of the biliopancreatic and alimentary limb interferes with the magnitude of weight loss. To evaluate if the length of these limbs is related to the percentage of weight loss, we performed this research. One hundred and twenty obese people were inserted into four groups: A) biliopancreatic limb with 50 cm length and alimentary limb with 100 cm length; B) biliopancreatic limb with 50 cm length and alimentary limb with 150 cm length; C) biliopancreatic limb with 100 cm length and alimentary limb with 100 cm length; D) biliopancreatic limb with 100 cm length and alimentary limb with 150 cm length. The weight loss was compared between groups. Data were collected preoperatively and one year after surgery. The follow-up occurred in 78.3% of the sample. The composition of the groups was similar, with no statistical significance. The average age was 43 years in groups A, C and D and 42 years in group B. The female gender predominated in all groups. The mean body mass index was 46 kg/m2 for groups A, C and D and 42 kg/m2 in group B. The percentage of total weight loss was 33% for group A and 34% for groups B, C and D. There was no significant difference among groups. So we concluded that different lengths of biliopancreatic and alimentary limbs do not affect the percentage of total weight loss.
