[Postoperative cholangiography using the T-drain canal]

Postoperative cholangiography using the T-drain canal (PCST) with flexible fibre endoscopes was done in five patients. Cases were palliative papillary drainage in malignant occlusion, passage of the intact papilla, expulsion of concrement through the cut papilla, bougienage of inflammatory bile duct stenosis with lavage removal of stone, and an endoscopic selective peripheral bile duct drainage. In one female bile duct stone wedging after endoscopic sphincterotomy of the papilla during chemical litholysis had occurred previously. For removal of residual concrements PCST competes with catheter extraction, chemolitholysis, dilatation of the papilla and endoscopic sphincterotomy. Thus far, complications are not serious. In cases of good cooperation between surgeon and endoscopist PCST could develop into a routine method.
