Small Intestinal Bacterial Overgrowth Obese (SIBOB)
March 25, 2024 updated by: Lille Catholic University
Modification of Digestive Flora After Gastric Bypass : Pilot Study on Microbial Overgrowth Using Gas Chromatography
The objective of this research is to determine the incidence of microbial overgrowth of the small intestine before and after a gastric bypass.
For this purpose, the study is based on the analysis of the expired hydrogen H2 with gas chromatography before surgery and at 1, 3, 6, 12, 18 and 24 months.
