The value of T-tube papillotomy is discussed. T-tube papillotomy is alternative method to the conventional endoscopic papillotomy in cases with T-tube drainage, if papillotome cannot be inserted into the common bile duct through the orifice of the papilla. It is easier to in-troduce papillotome into the common bile duct, the papilla of Vater and the duodenum via T-tube. The correct direction and the length of incision can be controled endoscopically. It is concluded that the described method will be useful when traditional endoscopic papil-lotomy fails.
