Comparison Between Pyloric Preserving and Non-Pyloric Preserving Bariatric Surgery With Glucose Challenge
Comparison Between Pyloric Preserving and Non-Pyloric Preserving Bariatric Surgery With Glucose Challenge

This study will compare glucose and simple carbohydrate sensitivity. The hypothesis is that rapid emptying of high-glycemic index foods after Roux-En-Y gastric bypass (RYGB) causes reactive hypoglycemia. It is believed that the controlled release offered by an intact pylorus will be advantageous for long term results in bariatric surgery. This study can provide a scientific rationale, in a short duration of time, for why pylorus sparing surgery, such as the sleeve gastrectomy or duodenal switch, may offer therapeutic advantages, as compared to non-pyloric sparing surgery, namely the gastric bypass.

Clinical Trial Objective:

The objective of this clinical trial is to determine whether an intact pylorus prevents reactive hypoglycemia following challenge with liquid glucose preparation and/or solid load made of refined flour product that is a simple carbohydrate.

Clinical Trial Design:

This is a prospective, non-randomized, clinical trial.
