Influence of Insulin Resistance Status on the Development of Gallstones Following Roux-En-Y Gastric Bypass: a Prospective Cohort Study.

Background: The occurrence of gallstones following Roux-en-Y gastric bypass (RYGB) has been extensively reported. As RYGB promotes improvement in insulin resistance (IR), which is one of the factors enrolled in the pathophysiology of gallstones, this study aims to determine the influence of IR and its post-RYGB course on the development of gallstones.

Methods: This is a prospective cohort study that enrolled 108 morbidly obese subjects free of gallstones which underwent RYGB and were followed up for 24 months, through clinical, laboratory, and ultrasound examinations.

Control of hypertension after roux-en-y gastric bypass among obese diabetic patients.

Context: Hypertension is a common disorder in general practice and has a widely known association with type 2 diabetes mellitus. Low adhesion to clinical treatment may lead to poor results. Obesity surgery can bring early and relevant resolution rates of both morbidities.

Impact of Roux-en-Y gastric bypass on metabolic syndrome and insulin resistance parameters.

Background: Metabolic syndrome (MetS) is a complex association of clustering metabolic factors that increase risk of type 2 diabetes mellitus (T2DM) and cardiovascular disease. Surgical treatment has become an important tool to achieve its control. The aim of this study was to evaluate the impact of Roux-en-Y gastric bypass (RYGB) on MetS and its individual components, clinical characteristics, and biochemical features.

Hepatic inflammatory pseudotumor: A case series.

Introduction: Inflammatory pseudotumor (IPT) is a rare lesion consisted of inflammatory and myofibroblastic cells. These lesions may be found in different organs. There are less than 300 described cases.
