Systematic review: Laparoscopic fundoplication for gastroesophageal reflux disease in partial responders to proton pump inhibitors

Figure 3 Effects of laparoscopic fundoplication on esophageal acid exposure (assessed by ambulatory 24-h H measurement) and resting lower esophageal sphincter pressure (assessed by esophageal manometry). Data are shown for before and after laparoscopic fundoplication (LF) (follow-up period: 0.25-1 year). A: Esophageal acid exposure [baseline taken during proton pump inhibitors (PPIs) treatment]; B: Lower esophageal sphincter pressure (LESP) (baseline taken during PPI abstinence).
