NCT ID: NCT03547765 Completed - Bariatric Surgery Clinical Trials

Sexual Health of Obese Men Before and After Bariatric Surgery.

BARIASSO
Start date: July 2, 2018
Phase:
Study type: Observational

Compare Male Health Sexual Questionnaire (MHSQ) before and after bariatric surgery to assess the sexual health of the obese men with a recommended and exhaustive tool. There are few data that evaluate the sexual health of this population.

NCT ID: NCT03522259 Completed - Bariatric Surgery Clinical Trials

Rivaroxaban as Thrombosis Prophylaxis in Bariatric Surgery

BARIVA
Start date: July 19, 2018
Phase: Phase 2
Study type: Interventional

The aim of this study is to investigate the efficacy and safety of rivaroxaban in obese patients undergoing bariatric surgery. The objectives are to assess the safety and feasibility of venous thromboembolism (VTE) prophylaxis and lung embolism with Rivaroxaban 10mg as an oral anticoagulant. After bariatric surgery patients receive the study medication Xarelto 10mg QD for 7, resp. 28 days. All clinically thromboembolic events will be assessed by ultrasound or CT, respectively, as soon as apparent. In addition, patients are screened for VTE at day 28 by ultrasound to detect clinically inapparent thromboses. In a subgroup of study patients (patients from the University Hospital Inselspital, Bern) PK/PD parameters are assessed following the last intake of rivaroxaban at day 28.

NCT ID: NCT03517345 Completed - Bariatric Surgery Clinical Trials

The Metabolic Effects of Prebiotic Supplementation After Roux-en-Y Gastric Bypass Surgery

Start date: April 22, 2013
Phase: N/A
Study type: Interventional

In this study, it is aimed to evaluate whether the addition of prebiotics to patients' post-operative diets increases Roux-en-Y Gastric Bypass surgery effects. Half of the participants were randomized prebiotic with conventional yogurt, while the other half were randomized only conventional yogurt as a snack

NCT ID: NCT03482895 Completed - Bariatric Surgery Clinical Trials

MINI Bypass Versus Roux-en-Y Bypass: Differences in HOrmonal Secretions at 2 Years of Surgery

MINIBHO
Start date: April 4, 2018
Phase:
Study type: Observational

Gastric bypass with omega loop technic (OLGB) seems to be as effective as gastric bypass roux-en-Y (RYGB the reference) for the management of obesity and type 2 diabetes, but with less early surgical complications and more undernutrition in long terms. This study aims to explore the profile of secretion of entero-insular hormone after a meal test in OLGB patient vs RYGB to understand the mechanisms of the improvement of type 2 diabetes after OLGB. Secondary objectives are to better understand the absorptive function of the gut after a gastric bypass, to understand why is there more undernutrition in long term after OLGB than after RYGB.

NCT ID: NCT03480464 Completed - Obesity Clinical Trials

App-technology to Improve the Level of Physical Activity After Bariatric Surgery

Start date: November 16, 2017
Phase: N/A
Study type: Interventional

The aim of this study is to investigate the effect of using new app-based technology to increase the level of physical activity, compared to conventional postoperative information given to patients undergoing bariatric surgery. The hypothesis is that the intervention, i.e. using the new technology, will have a greater positive effect on levels of physical activity and outcomes of weight loss than conventional postoperative information.

NCT ID: NCT03469635 Completed - Bariatric Surgery Clinical Trials

Nutritional Status During Pregnancy After Bariatric Surgery

PREGNUTRIBAR
Start date: January 2006
Phase:
Study type: Observational

Background: There is a lack of evidence on whether maternal nutritional deficiencies after Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) affect fetal development. The investigators hypothesis is that SG could induce nutritional deficiencies during pregnancy, as RYGB does, because of food restriction. These nutritional deficiencies may alter fetal growth. Methods: Women with singleton pregnancies who had at least one nutritional evaluation during pregnancy in our institution between 2006 and 2017 were included. The investigators evaluated nutritional deficiencies according to standard and pregnancy-specific norms. They have planned to study the relationships between these parameters and fetal growth. Objectives: To compare maternal nutritional parameters and neonatal outcomes after RYGB and SG and to assess the impact of nutritional alterations on fetal growth.

NCT ID: NCT03440138 Completed - Bariatric Surgery Clinical Trials

Defining Benchmarks in Bariatric Surgery

BBenchmarks
Start date: October 17, 2017
Phase:
Study type: Observational

Aim: To define benchmark outcomes in minimally-invasive primary bariatric surgery. Design: Multicenter retrospective cohort study. Assessed outcomes: Morbidity as defined by the Clavien-Dindo classification for surgical complications, the Comprehensive Complication Index® (CCI®) at discharge, at 3 months and at latest follow-up. Evolution of body mass index (BMI) will be also analyzed. Hospital eligibility: High volume centers (> 200 bariatric operations per year) from at least three continents, maintaining a prospective database, as well as having published previously critically on their outcome. Study population: Adult patients who underwent primary minimally invasive (laparoscopic / robotic) Roux-en-Y gastric bypass or sleeve gastrectomy from 1st of June 2012 to 31st of May 2017. Patient Exclusion criteria: detailed later. Data collection Deadline: 1st September 2017 - 30 April 2018

NCT ID: NCT03331536 Completed - Osteoporosis Clinical Trials

Skeletal Health in Bariatric Surgery Patients

Start date: March 22, 2018
Phase:
Study type: Observational

The investigators propose a prospective cohort trial that will help to understand the impact of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) in pre- and post-menopausal female bariatric patients.

NCT ID: NCT03200782 Completed - Bariatric Surgery Clinical Trials

Postprandial Hypoglycemia in Patients After Bariatric Surgery With Empagliflozin and Anakinra - The Hypo-BEAR-Study

Hypo-BEAR
Start date: May 30, 2017
Phase: N/A
Study type: Interventional

The purpose of the study is to investigate whether hypoglycaemia observed after food intake in bariatric patients can be either influenced by an SGLT2 inhibitor, empagliflozin, or via inhibition of inflammation with an human interleukin-1 receptor antagonist (IL1-RA, anakinra).

NCT ID: NCT03195504 Completed - Bariatric Surgery Clinical Trials

High-flow Nasal Oxygenation in Obese Patients During Apnea

Start date: August 10, 2017
Phase: N/A
Study type: Interventional

Before going off to sleep patients are given oxygen to saturate blood with oxygen to extend time before a decrease in the level of oxygen in the blood occurs. During this period, obese patients have a faster decrease in the level of oxygen in their blood. This study uses a device called "high-flow nasal cannula" (HFNC), which delivers humidified high-flow oxygen through 2 small plastic tubes placed just inside nostrils. In the intensive care unit settings this device has been used extensively and has become a standard practice. Purpose of this study is to determine whether these high-flow nasal cannula increase the time safely when going to sleep during elective surgery.
