[Biliary leaks after liver resection. Prevention and treatment]. / Gallenleckage nach Leberresektion. Vermeidung und Behandlung.

ABSTRACT

The surgical treatment of primary and secondary liver pathologies is nowadays standard practice. Since the first major resections performed by Langenbruch in 1888 there have been significant developments in the surgical technique. In addition to the surgical technique, the diagnostics and patient selection, perioperative care and anesthetic management as well as knowledge of liver anatomy and physiology have also shown significant developments. The proportion of complex operations, even within the framework of multimodal concepts has also increased. Despite this increasing complexity, the morbidity (< 45 %) and mortality (< 5 %) of liver surgery could be clearly reduced; however, the incidence of postoperative biliary leaks in large published series currently lies between 0 % and 30 % and has only shown a minimal reduction in recent years. The management of bile leakage requires an interdisciplinary management involving endoscopic and radiological, interventional or operative therapy. Most leakages (69-94 %) persist under conservative treatment (drainage and if necessary antibiotic therapy). For high volume fistulas and persistent biliary leakage endoscopic retrograde cholangiography (ERC) with stent placement represents the therapy of choice. Infections with biliary peritonitis and failure of interventional strategies often require revision surgery, possibly consisting of suturing if a leakage is identifiable, replacement of drainages or application of a bile duct drainage (e.g. T-drain or transhepatic external biliary drainage).
