Management of Gallbladder Neck Stones

Diagnosis and Evaluation

The British Society of Gastroenterology recommends evaluating for signs of common bile duct (CBD) obstruction, including abnormal liver function tests, dilated bile duct on ultrasound, history of jaundice or pancreatitis, and signs of cholangitis, in patients with gallbladder neck stones 1
Patients with gallbladder neck stones without evidence of CBD stones can proceed directly to laparoscopic cholecystectomy, with intraoperative cholangiography (IOC) considered for those with intermediate to high pre-test probability of CBD stones 1

The British Society of Gastroenterology guidelines state that cholecystectomy is the treatment of choice for gallbladder stones, including those at the neck, and ERCP should be reserved for patients with confirmed or highly suspected common bile duct stones 1
Cholecystectomy alone for gallbladder neck stones (without CBD stones) provides excellent outcomes with low morbidity and mortality, and is the definitive treatment for symptomatic gallstones, preventing recurrent biliary events and improving quality of life 1
For patients with prohibitive surgical risk, biliary sphincterotomy and endoscopic duct clearance may be considered as an alternative, but this approach should be reserved for those who cannot undergo surgery 1

ERCP should be reserved for patients with clear evidence of CBD stones, as unnecessary ERCP increases procedural risks without benefit 1
ERCP carries risks including pancreatitis, bleeding, and perforation, and should only be performed when necessary 1

Stones at the gallbladder neck may increase the risk of migration into the CBD, but this alone is not an indication for ERCP 1
The presence of stones at the gallbladder neck may cause Mirizzi syndrome (compression of the common hepatic duct), which requires careful surgical management but not necessarily ERCP 1
