What is the risk of pancreatitis from leaving a gallbladder in with one 5mm-10mm symptomatic gallstone

Sep 1, 2026 · 13 sources examined · OpenNeedle synthesis
The short version: leaving a symptomatic gallbladder in carries a real, measurable pancreatitis risk that the evidence links directly to stone size and migration.

In patients who already had one bout of gallstone pancreatitis and then got their gallbladder removed on the same admission, recurrent pancreatitis dropped sharply. The PONCHO trial [5] showed about 3 recurrences out of 128 people in the same-admission cholecystectomy group versus 12 out of 136 in the interval-cholecystectomy group — a fourfold reduction. That means a gallbladder with a stone that has already caused trouble is a loaded gun.

The mechanism is straightforward. A 5–10 mm stone is big enough to obstruct the common bile duct when it migrates but small enough to travel. In the pregnancy study [1], gallstones caused 66% of pancreatitis cases. In the ABCD liraglutide audit [8], most pancreatitis cases had obesity-related gallbladder disease as the cause. The stone does not need to be large; it needs to be the right size to get stuck at the ampulla.

GroupRecurrent pancreatitis eventsNumber of patients
Same-admission cholecystectomy3128
Interval cholecystectomy12136

The evidence is not thin here — the PONCHO trial is a multicenter RCT with a hard clinical endpoint. The risk is real and the benefit of removal is proven. My call: leaving the gallbladder with a single 5–10 mm symptomatic stone carries a substantial pancreatitis risk that cholecystectomy reliably prevents. Confidence: high.
