ABSTRACT

Bile leakage and postoperative bile duct strictures or anastomotic stenosis after bilioenteric anastomosis are complex surgical complications, which are associated with increased morbidity and mortality. Detailed diagnostics and sophisticated decision-making is always requiered. Complex liver surgery (redo procedures, nonanatomic resections, etc.) and surgery involving the liver hilum or exposure of the intraparenchymal Glissonean sheath are risk factors for postoperative bile leakage. Bile leakage is defined as a bilirubin concentration at least three times greater than the serum bilirubin measured in an abdominal drainage on or after the third postoperative day or as the need for radiologic intervention because of biliary collection or relaparotomy for bile peritonitis. Therapeutic strategies for bile leakage comprise conservative watch and wait, interventional procedures (endoscopic or percutaneous biliary drainage) and relaparotomy and are selected based on the postoperative onset, output volume and anatomic localization of the bile leak. Conservative treatment and interventional procedures show a high success rate and should therefore be considered as the treatment of choice in most cases. In contrast to bile leakage, bile duct strictures and anastomotic stenosis are rarely observed after surgery and can usually be treated by interventional procedures. This review article discusses situation-dependent specific treatment of postoperative bile leakage as well as bile duct strictures and anastomotic stenosis in detail.

ABSTRACT

Cholangiocarcinoma (CCC) is the second most common primary malignancy of the liver and is typically diagnosed at advanced disease stages. Among curative treatment options for CCC, radical surgical resection with extrahepatic bile duct resection, hepatectomy, and en-bloc lymphadenectomy are considered the mainstay of curative therapy. The assessment of the functional liver reserve by dynamic liver function tests and the estimation of the remaining future liver volume (future liver remnant, FLR) are of paramount importance. The introduction of novel interventional and surgical techniques, such as portal vein embolization, associating liver partition, and portal vein ligation for staged hepatectomy (ALPPS), have enabled clinicians to achieve resectability even in patients previously deemed unresectable. Radiofrequency ablation (RFA) shows acceptable results in small intrahepatic cholangiocarcinoma (IHCC) in liver cirrhosis and should be evaluated if cirrhosis precludes surgical treatment. Transarterial chemoembolization (TACE) or transarterial radioembolization (TARE) alone or in combination with systemic therapy may be applied in cases of surgical irresectability. According to recent results of the British BILCAP trial, adjuvant therapy may be considered after surgical resection in curative intent.
