Brief summary

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.

Detailed description

Consecutive morbidly obese patients selected for LSG are included in a prospective clinical study. Gastroesophageal function is evaluated using a clinical validated questionnaire, upper endoscopy, esophageal manometry and 24-h pH monitoring before and 24 months after LSG.

Design outcomes

Primary

MeasureTime frameDescription
Change from baseline in DeMeester's scorebaseline, 24 months after LSGUse of the composite score that evaluates GER at 24-h pH monitoring before and 24 months after LSG. It includes numbers of reflux episodes, upright time in reflux, recumbent time in reflux, total time in reflux, reflux episodes over 5 minutes, longest reflux episodes

Secondary

MeasureTime frameDescription
Change from baseline in lower esophageal sphincter pressurebaseline, 24 months after LSGEsophageal manometry measures several parameters including lower esophageal sphincter pressure
Change from baseline in amplitude of esophageal peristaltic wavesbaseline, 24 months after LSGEsophageal manometry evaluates quality and amplitude of esophageal peristalsis
Change from baseline in grade of esophagitisbaseline, 24 months after LSGUpper endoscopy is performed to assess preoperative and postoperative presence and severity of esophagitis
Change from baseline in Gastroesophageal reflux disease Symptom Assessment Scale scoreBaseline, 24 months after LSGStandard and validated questionnaire is used to assess gastroesophageal symptoms and quality of life
