Impact of Laparoscopic Gastric Bypass Surgery and Weight Reduction on Lower Esophageal Sphincter (LES)

NCT01672034 · Status: WITHDRAWN · Type: OBSERVATIONAL

Last updated 2014-11-05

No results posted yet for this study

Summary

The purpose with this study is to investigate whether gastric bypass surgery and the following weight reduction impact the tone in esophageal sphincters and the esophageal function.

In a previous study our group used high resolution solid-state manometry to investigate the pressure in the esophagus and esophageal sphincters in obese patients going through laparoscopic bariatric surgery. These studies showed that the barrier pressure between the stomach and esophagus is significantly lower in obese compared to lean patients. In this study the investigators will examine these patients once more, now after weight reduction to see whether the barrier pressure is back to normal compared to lean patients.
