Weight loss and adherence to postoperative follow-up after vertical gastrectomy for obesity treatment.

Purpose: To analyze the effectiveness of vertical gastrectomy in the treatment of obese patients, adherence to clinical follow-up and the influence of factors such as gender and age.

Methods: This is a retrospective, observational and descriptive study, conducted with patients undergoing vertical gastrectomy, operated at Hospital São Domingos, between January 2016 and July 2018.

Results: Most patients undergoing vertical gastrectomy were female (n = 193, 72.

VERTICAL GASTRECTOMY VS. EXTENDED VERTICAL GASTRECTOMY: WHAT IS THE IMPACT ON GASTROESOPHAGEAL REFLUX DISEASE IN OBESE RATS?

Background: Extended vertical gastrectomy is a variation of the vertical gastrectomy technique requiring studies to elucidate safety in relation to gastroesophageal reflux.

Aim: To analyze comparatively vertical gastrectomy (VG) and extended vertical gastrectomy (EVG) in rats with obesity induced by cafeteria diet in relation to the presence of reflux esophagitis, weight loss and macroscopic changes related to the procedures.

Methods: Thirty Wistar rats were randomized into three groups, and after the obesity induction period by means of a 28-day cafeteria diet, underwent a simulated surgery (CG), VG and VGA.

Comparative analysis between patients undergoing Gastric Bypass and Sleeve Gastroplasty in a private hospital in Sao Luis-MA.

Purpose: To compare the satisfaction levels about the surgery and anesthesia management, and to analyze the postoperative outcomes of patients undergoing Gastric Bypass and Sleeve Gastroplasty surgeries in a private hospital in Sao Luís-MA.

Methods: The sample consisted of patients undergoing Bypass and Sleeve bariatric surgeries from August 2018 to August 2019, who were in the range of 18 and 70 years old and had not used drugs or presented cardiac arrhythmias, dilated cardiomyopathy, and conduction disorder heart. Data were collected from the evaluation forms and recorded in a form with closed questions.

Assessment of the Effect of Perioperative Venous Lidocaine on the Intensity of Pain and IL-6 Concentration After Laparoscopic Gastroplasty.

Background And Objectives: Opioids are associated with sedation and respiratory depression. The primary objective of this study was to assess pain intensity after gastric bypass with lidocaine. The secondary objective was to assess the IL-6 concentration, consumption of morphine, time to morphine request, time to extubation, and side effects.

A Prospective Single-Arm Trial of Modified Long Biliopancreatic and Short Alimentary Limbs Roux-En-Y Gastric Bypass in Type 2 Diabetes Patients with Mild Obesity.

Background: Type-2 diabetes (T2D) patients with body mass index (BMI) below 35 kg/m carry lower remission rates than severely obese T2D individuals submitted to "standard limb lengths" Roux-en-Y gastric bypass (RYGB). Mild-obese patients appear to have more severe forms of T2D, where the mechanisms of glycemic control after a standard-RYGB may be insufficient. The elongation of the biliopancreatic limb may lead to greater stimulation of the distal intestine, alterations in bile acids and intestinal microbiota, among other mechanisms, leading to better metabolic outcomes.

FIXING JEJUNAL MANEUVER TO PREVENT PETERSEN HERNIA IN GASTRIC BYPASS.

Background: Among Roux-en-Y gastric bypass complications is the occurrence of intestinal obstruction by the appearance of internal hernias, which may occur in Petersen space or the opening in mesenteric enteroenteroanastomosis.

Aim: To evaluate the efficiency and safety in performing a fixing jejunal maneuver in the transverse mesocolon to prevent internal hernia formation in Petersen space.

Method: Two surgical points between the jejunum and the transverse mesocolon, being 5 cm and 10 cm from duodenojejunal angle are made.

Technical modification for sleeve gastrectomy.

Introduction: The surgical technique of sleeve gastrectomy has not been fully standardized and, therefore, there are issues to be solved. There is a tendency to increase its application due to proved efficiency in weight loss, low morbidity and good postoperative results. However, gastroesophageal reflux disease, which can result from it, is still not well understood.
