NCT ID: NCT06350955 Not yet recruiting - Clinical trials for Roux-en-Y Gastric Bypass

IV Iron-induced Hypophosphatemia After RYGB

IVORY
Start date: May 2024
Phase: Phase 4
Study type: Interventional

The primary objective of the study is to compare the incidence of hypophosphatemia in RYGB patients treated with intravenous (IV) single dose of iron isomaltoside (Monofer®) or ferric carboxymaltose (Ferinject®).

NCT ID: NCT05560789 Completed - Physical Activity Clinical Trials

The Effect of Physical Activity in Individuals With Post-bariatric Hypoglycemia

Start date: January 3, 2023
Phase: N/A
Study type: Interventional

The goal of this pilot study is to evaluate the magnitude of changes in glucose and hormone levels in response to structured exercise in the fasting state in individuals with post-bariatric hypoglycemia (PBH). This pilot study will assess the adequacy of a protocol to test the following hypotheses: (1) hypoglycemia will develop in individuals with PBH in response to exercise; (2) counterregulatory hormonal responses to hypoglycemia during exercise are impaired in individuals with PBH.

NCT ID: NCT05250271 Completed - Clinical trials for Roux-en-Y Gastric Bypass

Forecasting and Preventing Post-Bariatric Hypoglycaemia WP 2

PBH Forecast
Start date: January 18, 2022
Phase: N/A
Study type: Interventional

The overall aim of this study is to develop a sustainable hypoglycemia correction strategy.

NCT ID: NCT05216926 Recruiting - Clinical trials for Roux-en-Y Gastric Bypass

Forecasting and Preventing Post-Bariatric Hypoglycaemia WP 3

PBH Forecast
Start date: January 18, 2022
Phase: N/A
Study type: Interventional

The overall aim of this study is to prevent hypoglycemic events in patients with hypoglycemia after a meal and to develop a sustainable hypoglycemia correction strategy.

NCT ID: NCT05212207 Completed - Clinical trials for Roux-en-Y Gastric Bypass

Forecasting and Preventing Post-Bariatric Hypoglycaemia WP 1

PBH Forecast
Start date: January 18, 2022
Phase:
Study type: Observational

The overall aim of this study is to prevent hypoglycemic events in patients with hypoglycemia after a meal and to develop a sustainable hypoglycemia correction strategy.

NCT ID: NCT04972357 Completed - Bariatric Surgery Clinical Trials

Bariatric Procedures and Changes Gastric Passage

BIP
Start date: October 1, 2018
Phase:
Study type: Observational

Gastric emptying measured with scintigraphy in patients after standard Roux-en-Y Gastric Bypass (S-RYGB), Banded-RYGB (B-RYGB) or Extended pouch-RYGB (E-RYGB).

NCT ID: NCT04933305 Completed - Obesity Clinical Trials

Microstructure of Ingestive Behavior and Body Weight Loss After Roux-en-Y Gastric Bypass

Drinkometer
Start date: April 1, 2019
Phase:
Study type: Observational

Studies of appetitive behavior in humans after RYGB have produced ambiguous results. It therefore remains unclear whether there are fundamental shifts in the palatability of high-fat and sugary foods after RYGB or simply a decrease in the appetitive drive to ingest them. Moreover, learning processes may play a role as changes in diet selection progress with time in rats after RYGB. However, direct measures of an altered food selection in humans after RYGB are rare and both the durability of the phenomenon as well as the role of experience for changes in food selection remain elusive.

NCT ID: NCT04808206 Recruiting - Obesity Clinical Trials

A Registry of Laparoscopic Bariatric Surgery Using Stapling Devices: Observation of Safety and Clinical Efficacy

STAP-JOLI
Start date: June 1, 2022
Phase:
Study type: Observational

The purpose of this observational registry is to evaluate the safety and the clinical efficacy of laparoscopic bariatric surgery using stapling devices (easyEndoTM Universal Linear Cutting Stapler and reloads from Ezisurg Medical). The goal of the study will be achieved by reporting peri- and postoperative complications and the clinical outcome after surgery in a prospectively maintained database.

NCT ID: NCT04609449 Completed - Bariatric Surgery Clinical Trials

A Comparison Between Short vs. Long Biliopancreatic Limb Gastric Bypass

Start date: January 2016
Phase: N/A
Study type: Interventional

Prospective study including patients submitted to RYGB (n=94) and L-RYGB (n=94) at a single institution. The aim was to compare the effect on comorbidities and weight loss of a long biliopancreatic limb Roux-en-Y gastric bypass (L-RYGB), compared with a standard RYGB. Procedure selection was randomly assigned (1:1), and surgeries were performed, during 24 months (2016-2017). Weight loss, comorbidities control and nutritional status were assessed at baseline and 12 months.

NCT ID: NCT04600596 Completed - Obesity, Morbid Clinical Trials

Photographic Food Recognition and Meal Size Estimation Before and After Roux-en-Y Gastric Bypass

Start date: June 1, 2019
Phase:
Study type: Observational

Direct measurements of changes in food selection in humans after RYGB have been limited by the unreliability of patients, which poses significant methodological and conceptual challenges to researchers and study design. Self-monitoring requires time and effort, and many find tracking of dietary intake tedious, which contributes to attrition. Direct measurements, however, represent an essential component in the attempt to understand how RYGB alters eating and food preferences, but laboratory settings preclude a real-life environment. The aim of this study is to investigate changes in food preferences, total energy intake of the three primary macronutrients and meal patterns between obese women (BMI ≥ 35) before and after Roux-en-Y gastric bypass and lean (BMI ≤ 25) and obese (BMI ≥ 35) controls by means of photographic food recognition with a mobile application.
