Management of Choledocholithiasis with Passed Stone

Immediate Clinical Assessment

The American Gastroenterological Association recommends checking for persistent cholangitis or biliary obstruction by looking for fever, jaundice, right upper quadrant pain, persistently elevated bilirubin, or dilated common bile duct on imaging in patients with choledocholithiasis who have passed a stone 1, 2
Evaluate for concurrent pancreatitis by assessing lipase/amylase levels and clinical symptoms, as gallstone pancreatitis commonly accompanies passed stones 1, 2

High-risk indicators requiring immediate ERCP include visible CBD stone on ultrasound, total bilirubin >4 mg/dL, CBD diameter >6 mm with gallbladder in situ, or persistent cholangitis, according to the American College of Gastroenterology 3, 4
Moderate-risk patients with bilirubin 1.8-4 mg/dL or abnormal liver biochemistries should undergo confirmatory imaging with MRCP or EUS before proceeding, as recommended by the American Gastroenterological Association 3, 4

Perform urgent ERCP within 24 hours if there is concomitant cholangitis with severe sepsis or clinical deterioration despite antibiotics, as advised by the American College of Gastroenterology 1, 2, 5
Perform early ERCP within 72 hours if there is high suspicion of persistent CBD stone or gallstone pancreatitis with evidence of persistent obstruction, according to the American Gastroenterological Association 1, 2, 5

The American College of Surgeons recommends performing cholecystectomy during the same hospital admission if possible to prevent recurrent biliary events 1, 2
If same-admission surgery is not feasible, schedule cholecystectomy within 2-4 weeks after discharge, as delaying beyond this timeframe significantly increases risk of recurrent biliary complications, according to the American Gastroenterological Association 1, 2

Be cautious in elderly patients, as complication rates from ERCP with sphincterotomy nearly double in this population, with mortality reaching 7.9%, as reported by the American Geriatrics Society 3, 5
Recognize that delaying cholecystectomy indefinitely increases recurrence rates, and the gallbladder remains the source of future stones without definitive surgical management, as stated by the American College of Gastroenterology 1, 2
