NCT ID: NCT06298162 Completed - Clinical trials for Bariatric Surgery Candidate

Assessment of Pouch Emptying With MRI After Roux-en-Y Gastric Bypass

MRI pouch
Start date: July 25, 2019
Phase:
Study type: Observational

A cross-sectional observational study in which pouch emptying rate is measured with MRI in good (TWL>35%) and bad responders (TWL<25%) two years after Laparoscopic Roux-en-Y Gastric Bypass (LRYGB).

NCT ID: NCT05715892 Not yet recruiting - Gastric Bypass Clinical Trials

Examining Patterns in the Involvement of Gastric Bypass Patients in Clinical Studies

Start date: February 2024
Phase:
Study type: Observational

Clinical trial participation has historically been heavily biased toward specific demographics. Several people will be invited to enroll in this study so that it may collect a variety of data about gastric bypass clinical trial experiences and identify barriers to participation as well as the causes of participants' failure or withdrawal. The information collected from this study can be used to improve patient experience and outcomes for future patients and an opportunity to contribute to the advancement of medical knowledge and treatments for gastric bypass.

NCT ID: NCT05640947 Recruiting - Hypoglycemia Clinical Trials

Endoscopic Ultrasound-guided Large Diameter Lumen-apposing Metal Stent Gastro-gastrostomy for Bypass Reversal in Patients With Roux-en-y Gastric Bypass

LABOR
Start date: January 30, 2023
Phase: N/A
Study type: Interventional

The primary objective of this open-label pilot study is to investigate whether an endoscopically placed lumen apposing metal stent is an effective alternative to surgery in patients that have a clear indication for reversal of their gastric bypass.

NCT ID: NCT05357443 Active, not recruiting - Gastric Bypass Clinical Trials

SH Dr. Chen Gastric Bypass Study

Start date: August 31, 2022
Phase: N/A
Study type: Interventional

Evaluation of serum gastrin levels and their effect on marginal ulcer formation.

NCT ID: NCT04884230 Completed - Obesity Clinical Trials

Oversewing Staple Line of The Gastric Remnant

Start date: February 5, 2017
Phase:
Study type: Observational [Patient Registry]

Background: Roux-en-Y gastric bypass (RYGB) is a surgery with low rate complications. However, it is not exempt from them, and 1-6% suffer complications such as postoperative bleeding. Many intraoperative techniques have been evaluated to reduce postoperative bleeding, like the oversewing or reinforcement of the staple line. This study aims to evaluate the rate of postoperative bleeding in the oversewing of the staple line of the gastric remnant group versus the stapling only group. Methods: This is a 2-center, case-control study. The investigators randomly selected two groups who underwent RYGB or OAGB: group A (n=225) with oversewing from 2019-2020 and group B (n=225) with stapling only between the period of 2017-2018; both groups with similar demographic characteristics.

NCT ID: NCT04832282 Recruiting - Gastric Bypass Clinical Trials

Napoleon Measurement of Gastrojejunal Anastomosis

Start date: June 14, 2021
Phase: Early Phase 1
Study type: Interventional

This is a clinical trial assessing the feasibility of the Napoleon device for measuring the gastrojejunal anastomosis (GJA). The study population is Roux-en-Y gastric bypass (RYGB) patients with weight regain undergoing an endoscopy at Bellevue Hospital Center or Brigham and Women's Hospital. investigators aim for a sample size of up to 100 cases. For each case, endoscopists will first visually estimate the diameter of the GJA by comparing its size to the upper endoscope. Then, they will measure the GJA with Napoleon. Investigators will compare the GJA measurements performed using visual estimation and Napoleon. A survey will be given to all endoscopists to assess the level of ease using Napoleon.

NCT ID: NCT04332289 Completed - Hypoglycemia Clinical Trials

Assessing Insulin Turnover Using an In-vivo Deuterated Water Experiment.

DEEP1A
Start date: July 9, 2020
Phase:
Study type: Observational

The primary objective of this study is to observe the kinetics of pre-stored and de-novo synthesized insulin that is secreted into the circulation using an in-vivo heavy water (D2O) labelling experiment in patients with postprandial hyperinsulinaemic hypoglycaemia (PHH) and non-surgical non-PHH controls.

NCT ID: NCT04082923 Completed - Obesity Clinical Trials

Effect of Meal Texture on Glucose-metabolism and Gut Hormone Response After Bariatric Surgery

Obesity
Start date: October 3, 2019
Phase: N/A
Study type: Interventional

The investigators want to evaluate the difference in glucose metabolism and intestinal hormonal response after a liquid meal versus a solid meal in patients after bariatric surgery.

NCT ID: NCT03673969 Withdrawn - Gastric Bypass Clinical Trials

Mini Gastric Bypass vs Roux enY Gastric Bypass

MGB vs RYGB
Start date: February 1, 2019
Phase: N/A
Study type: Interventional

The primary aim of this research project is to assess the safety and efficacy of the MGB operation in the UK

NCT ID: NCT03585413 Completed - Obesity Clinical Trials

Impact of a Specific Micronutrient-probiotic-supplement on Fatty Liver of Patients After Mini-Gastric Bypass Surgery

FMG-01
Start date: August 31, 2018
Phase: Phase 3
Study type: Interventional

Aim of this prospective randomized intervention study is to evaluate the effect of a dietary intervention with a specific micronutrient-probiotic-combination for 12 weeks on fatty liver and cardiometabolic status in obese, nonalcoholic fatty liver disease (NAFLD) patients after Mini-Gastric Bypass (MGB) surgery.
