The Use of EndoFlip as a Clinical Tool for the Prediction of Postoperative GERD After Sleeve Gastrectomy

The Use of EndoFlip as a Clinical Tool for the Prediction of Postoperative GERD After Sleeve Gastrectomy

This study aims to determine if preoperative EndoFlip measurement can effectively predict postoperative GERD-related quality of life and lower esophageal acid exposure.

Enrolled patients will be subjected to a pre-operative gastroscopy, 48-Hour Bravo pH study and EndoFlip. In addition, each patient will complete a GERD-related quality of life questionnaire (GERD-HRQL scale). One year after surgery, patients will undergo a follow up a gastroscopy, pH study, EndoFlip and the same quality of life questionnaire to predict the incidence of postoperative GERD and determine the effect of sleeve gastrectomy.

Inclusion Criteria:

• Age between 18 and 65 years old

Exclusion Criteria:

• Hiatal hernia > 2 cm at preoperative gastroscopy
• Erosive esophagitis at preoperative gastroscopy
• Barrett's metaplasia/dysplasia at preoperative gastroscopy
• Revision surgery before the end of the study
• Pregnancy during the study period
• Actively bleeding esophageal varices
