Suction drainage of the gallbladder bed does not prevent complications after cholecystectomy: a random control clinical trial.

Some surgeons drain the gallbladder bed routinely, some selectively and some not at all. We aimed to clarify this confusion by entering 155 consecutive patients undergoing emergency and elective cholecystectomy without exploration of the common bile duct into a random control clinical trial. In 78 patients a 3 mm suction drain was left in the gallbladder bed and in 77 the abdomen was closed without drainage. There were no withdrawals, one death (in the drainage group) from myocardial infarction and one intraperitoneal abscess complicating postoperative pancreatitis (in the no-drainage group). Other events studied were postoperative pyrexia, wound infection, respiratory tract infection and duration of hospital stay. In none of these did the two groups differ either clinically or statistically. We conclude that drainage or non-drainage of the gallbladder bed must remain a matter of individual preference.
