[Elimination of the Kehr's drainage]

Two proven procedures are suggested for the substitution of T-drainage. 1. Modified coledochoduodenostomy, i.e. an internal shunt. By this precedure the operative mortality of aged jaundiced patients at risk could considerably be reduced. The key to success in this case is a broad anastomosis. 2. Patients of normal strength are subjected to sphincterectomy through transduodenal exposure and spincter replacement is performed after cleaning of the biliary ducts. The operated area is bridged by trans-cystically placed thin polyethylene tubing. Both procedures have rendered unnecessary the use of T-drainage.
