[Two-step removal of Kehr's drain from the common bile duct]

The removal of Kehr's drain from the common bile duct is not an indifferent procedure. In about 5% of cases complications develop, as described. Two-step removal of T drain prevents accumulation of bile around the defect in the common bile duct and development of such complications as massive escape of bile, septic complications, biliary peritonitis. In a group of 167 patients with T drain in whom the drain was removed in one step, three cases of serious complications developed, and in the group of 120 patients with two-step removal of T drain no complications were noted.
