We found no significant differences between different types of drains .
Drains increase the harms to the patient without providing any additional benefit for patients undergoing open cholecystectomy and should be avoided in open cholecystectomy
BACKGROUND Cholecystectomy is the removal of gallbladder and is performed mainly for symptomatic gallstones .
Although laparoscopic cholecystectomy is currently preferred over open cholecystectomy for elective cholecystectomy , reports of r and omised clinical trials comparing the choice of cholecystectomy ( open or laparoscopic ) in acute cholecystitis are still being conducted .
Drainage in open cholecystectomy is a matter of considerable debate .
Surgeons use drains primarily to prevent subhepatic abscess or bile peritonitis from an undrained bile leak .
Critics of drain condemn drain use as it increases wound and chest infection .
OBJECTIVES To assess the benefits and harms of routine abdominal drainage in uncomplicated open cholecystectomy .
A controlled trial of drainage after cholecystectomy
A prospect i ve controlled trial of drainage  after cholecystectomy has been carried out . In a consecutive series of 143 patients undergoing cholecystectomy , 50 patients were r and omly allocated to a drainage group and a further 50 patients to a non‐drainage group . The remaining 43 patients were drained electively because the common bile duct was explored or because of infection or incomplete haemostasis
