Spontaneous Bile Duct Perforation Mechanisms and Clinical Management

Spontaneous bile duct perforation is an uncommon but serious condition in which a breach occurs in the biliary tree without preceding trauma or iatrogenic injury. Although reported more often in infants and young children, adult cases have been increasingly recognised, frequently in association with gallstones, pancreaticobiliary maljunction or intrinsic wall weakness. Mechanistically, perforation arises when raised intraductal pressure overwhelms the structural integrity of the bile duct wall, or when congenital or acquired weaknesses predispose to rupture. Clinical presentation is often non-specific, with abdominal pain, distension, fever, jaundice and signs of peritonitis. Early diagnosis relies on a combination of ultrasonography, computed tomography and diagnostic paracentesis to detect bile-stained ascites. Management strategies range from conservative drainage and endoscopic stenting through to surgical repair with biliary drainage devices, cholecystectomy or biliary reconstruction such as hepaticojejunostomy. Prompt recognition and tailored intervention are critical to mitigate morbidity and mortality. Recent advances in imaging and minimally invasive endoscopic techniques have improved diagnostic accuracy and reduced the need for extensive laparotomy. Multidisciplinary care pathways and standardised algorithms are emerging to guide timely decision-making and optimise patient outcomes globally.

Spontaneous Bile Duct Perforation Mechanisms and Clinical Management publication trend

The graph below shows the total number of articles in spontaneous bile duct perforation mechanisms and clinical management across all publications each year (not limited to Nature Index journals).

Technical terms

Bile duct perforation: A full-thickness tear in the biliary tree leading to leakage of bile into the peritoneal or retroperitoneal space.

Bile peritonitis: Inflammation of the peritoneum caused by spillage of bile, typically presenting with severe abdominal pain and signs of systemic inflammation.

Pancreaticobiliary maljunction: A congenital anomaly in which the pancreatic and biliary ducts join outside the duodenal wall, predisposing to reflux and ductal injury.

Intraductal pressure: Hydrostatic force within the bile ducts, which when elevated may cause distension and eventual rupture of the duct wall.

Biloma: A localized collection of bile outside the biliary tract, most commonly occurring within the peritoneal or retroperitoneal spaces.
