Active clinical trials for "Obesity, Morbid"

The first-pass metabolism (FPM) is a barrier to the toxicity of ethanol. Changes to the size and function of the stomach may alter FPM. Bariatric surgery, like the gastric bypass procedure, involves significant changes to the size and function of the stomach and leads to more rapid gastric emptying. Consequences will be faster absorption and higher peak concentration of ethanol after surgery than before. There are growing concerns that surgery for obesity in this way may cause alcohol abuse. In this study the investigators compare changes in FPM of ethanol following two different bariatric surgical procedures.

BACKGROUND Unpredicted difficult tracheal intubation (DTI) with Macintosh laryngoscopy occurs frequently in obese patients. We investigated the incidence of DTI using the GlideScope® videolaryngoscope (GVL) with an algorithm based on a pre-operative assessment with the El Ganzouri Risk Index (EGRI). METHODS We prospectively enrolled morbidly obese patients (BMI>40 kg/m2) undergoing abdominal surgery. Patients were scheduled for flexible fibre optic bronchoscopic intubation (FFBI) or GVL intubation if the EGRI score was ≥7 or <7, respectively. The primary outcome was the occurrence of DTI that was defined as Cormack and Lehane (C&L) grades ≥III, Intubation Difficulty Scale (IDS)>5 and modified IDS (mIDS)>5. A numeric rating scale (NRS) was also used. Secondary outcomes included intubation success during the first attempt, the time to Cormack (TTC), the time to intubation (TTI), failure to intubate, oxygen desaturation and difficult ventilation.

The main aim of this study is to analyze and report traditional, patient-centered, and composite intermediate-term outcomes after laparoscopic revision Roux-en-Y gastric bypass surgery for weight recidivism.

Glycemic control is rapidly restored in patients with insulin resistance after bariatric surgery, in particular after the mal-absorptive one (i.e. Bilio-pancreatic diversion, BPD). To evaluate the mechanisms allowing restoration of insulin sensitivity after BPD the investigators aimed at identifying by using a proteomic approach plasma proteins or peptides that may be involved in the remarkably fast and explicit restoration of insulin sensitivity. In addition to the unbiased proteomics approach, a selection of recognized markers for metabolic control will be measured. These efforts all aim at an increased understanding of how insulin sensitivity is regulated and may provide novel ideas of how to treat insulin resistance and type 2-diabetes.

The purpose of this study is to determine whether the participants have improved their scores on health related quality of life (HRQL) 1 year after completing a learning and mastery course and whether sociodemographic variables are associated with HRQL.

The purpose of this study is to evaluate the results patients are obtaining with the Realize™ Adjustable Gastric Band-C during the first 24 months after surgery.

Impact of resected gastric volume on postoperative weight loss after laparoscopic sleeve gastrectomy for morbid obesity. Observational study with a mathematical method to approximate the calculation of the resected gastric volume after a sleeve gastrectomy and see the outcome on weight loss.

Between January and December 2012, a total of 40 patients underwent GLP. The study will assess subject excess weight loss (%EWL) following the study procedure at 3, 6, 12, 36 and 60 months.

From the beginning of March 2020, lockdown regimens prevented patients with obesity from receiving bariatric surgery. Surgical emergencies and oncological procedures were the only operations allowed in public hospitals. Consequently, patients with morbid obesity were put in a stand-by situation. With the aim at exploring physical and psychological conditions of the investigators future bariatric surgery patients, the investigators built a Questionnaire concerning obesity and COVID-19.

A study to explore the relationship between early weight loss in the 4 weeks following laparoscopic sleeve gastrectomy and outcomes, in terms of weight loss and comorbidity improvement, 7 years following the surgery.
