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 .
Abdominal drainage following cholecystectomy: high, low, or no suction?
A prospect i ve trial to assess the effect of  suction in an abdominal drain  following cholecystectomy was carried out . Three types of closed drainage system were compared : a simple tube drain , a low negative pressure drain , and a high negative pressure drain :  120 consecutive patients undergoing cholecystectomy were r and omly allocated to one of the three drainage groups . There was no significant difference in postoperative pyrexia , wound infection , chest infection , or hospital stay . This study failed to demonstrate any clinical ly useful difference between high negative pressure , low negative pressure , and static drainage system were compared : a simple tube drain , a low negative used , suction is not necessary and a simple tube drain ( greater than 6 mm internal diameter ) is the most effective form of drainage
