Severe Obesity Clinical Trial
Official title:
Evaluation of L-Cell Activity in the Small Intestine as Biliopancreatic Loop Extension in Obese Patients With DM2 Submitted to Roux-en-Y Gastric Bypass
Prevalence of Obesity and its association with Diabetes Mellitus 2 (DM2) affect a significant percentage of the world's population with great socioeconomic impact, especially for developing countries. Several procedures and interventions are used in its treatment, and the most efficient and with a positive impact on the life of patients with severe obesity and DM2 is Bariatric Surgery. The objective of is analyze the activity of L cells according to the extension of the bilio-pancreatic loop in T2DM patients undergoing GDYR. This study 20 adults of both sexes, above 18 years,before and 6 moths after surgery baritric metabolic, randomized the bilio-pancreatic loop in a proportion of 1:1. Keywords: Roux-en-Y gastroplasty, Immunohistochemistry, L cell, GLP-1, type 2 diabetes.
