BP Limb Length as a Factor for T2DM Remission

Abstract

Background: There has been increased interest in identifying the associated factors to Type 2 Diabetes Mellitus (T2DM) remission after bariatric surgery. One of these factors is the BP limb length. The objective of our study was to evaluate the T2DM remission rate in patients subjected to Roux -en- Y gastric bypass (RYGB) who had different Biliopancreatic (BP) limbs length. Methods: 48 patients with obesity grade II, and T2DM diagnosis, were subjected to RYGB and completed a one year of surgical follow up. All patients were grouped according to the BP limb length: In group A (n= 24) patients with BP limbs of 100 cm or less; in group B (n= 24) patients with BP limb from 150 to 170 cm in length. Results: Both groups presented an elevated remission rate of T2DM (83% full remission in the population studied). In group A 18 patients (75%) presented a full remission, while 2 patients (8.3%) showed a partial remission and only 4 patients (16.7%) were considered without remission at the one year follow up. In group B all patients had some remission: 22 patients (91.7%) presented a full remission (91.7%) and the rest of the patients showed a partial remission (8.3%), no significant difference was found between the two groups. Conclusions: Bariatric surgery remains as the best long term treatment for obesity and its comorbidities, despite some differences in the RYGB technique, BP limb length from 50 to 170 cm did not affect post RYGB glycemic control.
