Biliary leakage, an uncommon complication following liver resection, can cause septic complications. When leaks occur, closed suction drains left at the time of abdominal closure or drains placed percutaneously usually allow spontaneous resolution within days or weeks. Major biliary fistulas, though rare, may require further intervention that includes endoscopic retrograde cholangiopancreatography and stent placement. Thus, any technique that reduces this complication is of interest to surgeons performing liver resection.
