Value of EGD in patients referred for cholecystectomy: a systematic review and meta-analysis

摘要

Background: As many as 33% of patients with symptomatic cholelithiasis report persisting abdominal pain after cholecystectomy, suggesting alternative causes of these symptoms. EGD may serve as a tool to identify additional symptomatic abdominal disorders beforehand to avoid unnecessary gallbladder surgery. There is controversy as to whether routine EGD before cholecystectomy is appropriate.
