Acute abdomen with jaundice: A clue to extrahepatic biliary tract perforation

INTRODUCTION: Among a plethora of causes of acute abdomen, spontaneous common bile duct perforation (SCBDP) resulting in biliary peritonitis is almost never envisaged. Since the term SCBDP is often misconstrued as absence of an identifiable cause of perforation, ‘nontraumatic perforation of CBD’ is also in parlance to exclude relatively common causes such as trauma and iatrogenic injuries. In adults, choledochal cyst, cholangitis, infection, pancreatitis, pancreatobiliary maljunction have been identified as causes of perforation, however, choledocholithiasis remains the most common cause associated with spontaneous perforation of extra hepatic bile duct. CASE PRESENTATION: Here we present three cases of a spontaneous common bile duct perforation that presented as acute abdomen with peritonitis. Clinical presentation, biochemical abnormalities, imaging details, treatment options, and outcome were studied. This study has been reported in line with the SCARE 2020 Guideline [1]. DISCUSSION AND CONCLUSION: Spontaneous perforation of the extrahepatic bile duct is a rare but important presentation of gallstones in adults and needs a high index of suspicion during day-to-day practice. Surgeons should seek out this uncommon diagnosis in the patient for early surgical intervention and appropriate drainage to ensure survival.
