Laparoscopic Sleeve Gastrectomy and Gastroesophageal Acid Reflux
Physiopathologic Evaluation of Esophageal Function After Laparoscopic Sleeve Gastrectomy
Symptomatic Gastroesophageal Reflux (GER) is considered by many a contraindication to laparoscopic sleeve gastrectomy (LSG). However, of the few studies that have investigated the relationship between LSG and GER the majority reported only changes in symptoms and manometric data, while assessment of GER using 24-hour pH monitoring is lacking.
The aim of this study is to evaluate the effect of LSG on GER in morbidly obese patients.
