[Morphological aspect of the development of stenosis and suture insufficiency in the common bile duct after choledochotomy and biliary anastomoses].

The formation of stenosis following choledochotomy, common duct injury and repair can be observed frequently. A severe complication following a common duct repair, which can almost span a defect of about 3 cm, is the insufficient suture. An insufficient blood supply of the suture margins and a seam which is standing under tension are quoted as reasons for insufficient suture. The extra- and intramural distribution of arterial blood supply of the superior part of common bile duct is described. The results are based on preparations of 25 dissections and further 6 dissections following to another special arterial injection method. The "main-streets" of arterial blood supply of the common bile duct are described and hints are given to the surgeon, how to avoid stenosis or ischemic margins following anastomosis of the common duct.
