Bile in the drain after cholecystectomy
A 46-year-old woman is on day 2 after an elective laparoscopic cholecystectomy for symptomatic gallstones. Overnight the subhepatic drain has produced 300 mL of bile-stained fluid. She is comfortable at rest but has mild right upper quadrant pain, a pulse of 96 and a temperature of 37.8 °C.
Questions & answers
Q1 How would you investigate her?
Bloods including FBC, CRP, LFTs and coagulation. Ultrasound first to look for a collection and duct dilatation. MRCP defines the biliary anatomy and the level of the leak without instrumentation; HIDA scanning confirms an active leak if MRCP is equivocal. CT is useful if sepsis is suspected and an undrained collection needs to be located.
Q2 What is the differential diagnosis for bile in the drain?
Leak from the cystic duct stump (the commonest source, usually a slipped or badly placed clip), leak from a subvesical duct of Luschka in the gallbladder bed, a partial or complete injury to the common bile duct or an aberrant right sectoral duct, and rarely a duodenal or hepatic injury. Retained stones in the common bile duct raise ductal pressure and keep a small leak open.
Q3 Outline the management of a controlled cystic duct stump leak.
Keep the drain in and resuscitate; antibiotics only if there is evidence of infection. The principle is to lower the pressure gradient between the bile duct and the duodenum: ERCP with sphincterotomy and/or a plastic stent closes the great majority of low-grade leaks within days. Any undrained collection is drained percutaneously. Surgery is reserved for failure of endoscopic control or a major duct injury.
Q4 How is a major bile duct injury classified and managed?
The Strasberg classification is standard: types A–D are minor leaks and lateral injuries, type E (Bismuth 1–5) is circumferential injury of the main duct. Type E injuries need referral to a hepatobiliary unit for a tension-free Roux-en-Y hepaticojejunostomy, ideally after sepsis is controlled and the anatomy is fully defined. Early specialist referral is the single strongest predictor of a good long-term outcome.
Q5 Which technical steps reduce the risk of this complication?
Achieving the critical view of safety before dividing any structure, staying on the gallbladder wall, avoiding thermal energy near the hilum, and converting or performing a subtotal cholecystectomy when inflammation obscures the anatomy.
