title: Intraoperative placement of external biliary drains for prevention and treatment of bile leaks after extended liver resection without bilioenteric anastomosis.
abstract: BACKGROUND
  Improved surgical techniques, substantial preoperative diagnostics, and advanced perioperative management permit extensive and complex liver resection. Thus, hepatic malignancies that would have been considered inoperable some years ago may be curatively resected today. Despite all this progress, biliary leakage remains a clinically relevant issue, especially after extended liver resection. Intraoperative decompression of bile ducts by means of distinct biliary drains is controversial. Although drainage is rarely used as a routine procedure, it might be useful in selected patients at high risk for biliary leakage.
  
  
  METHODS
  We describe surgical management of long-segment exposed or injured bile ducts after extended parenchymal resection with concomitant lymphadenectomy. Because blood supply to the bile duct may be impaired, the risk of biliary necrosis and/or leakage is significant. Internal splinting of the bile duct to ensure optimum decompression plus guidance might be helpful. Thus, in selected cases after trisectionectomy we inserted an external-internal or internal-external drain into long-segment exposed bile ducts. For internal-external drains the tube was diverted via the major duodenal papilla into the duodenum and then transfixed after the duodenojejunal flexure through the jejunal wall by means of a Witzel's channel.
  
  
  RESULTS
  Because the entire bile duct is splinted, this technique is superior to bile duct decompression with a T-tube. This is supported by the course of a patient suffering biliary leakage after extended right-sided hepatectomy for colorectal metastasis. Initially, a T-tube was inserted for decompression, but biliary leakage persisted. After inserting transhepatic external-internal drainage, bile leakage stopped immediately. The patient's course was then uneventful. Five other patients (mostly with locally advanced hepatocellular or cholangiocellular carcinoma) treated similarly were discharged without complications. Drain removal 6 weeks postoperatively was uncomplicated in five of the 6 patients. In the sixth patient, external-internal drainage was replaced by a Yamakawa-type prosthesis for a biliary stricture. None of the patients suffered severe complications during long-term follow-up.
  
  
  CONCLUSIONS
  The bile duct drainage technique presented in this study was useful for preventing and treating bile leakage after long-segment exposure of extrahepatic bile ducts during major hepatectomy. Transhepatic or internal-external drains are often used for bilioenteric anastomoses, but similar drainage techniques have not been reported for the native bile duct. T-tubes are generally used in this situation. In particular cases, however, inner splinting of the bile duct and appropriate movement of the bile via a tube can be helpful.
