Acute recurrent pancreatitis results most commonly from gallstone disease. Although transabdominal ultrasound is a common procedure for evaluating biliary tract, it may not be effective in minilithiasis. We here report a case of acute recurrent pancreatitis, in which endoscopic ultrasonography revealed minilithiasis in the gallbladder with a review of the literature. A 57-year-old woman had suffered from idiopathic recurrent pancreatitis four times for the past 4 months. While transabdominal ultrasonography and abdominal computerized tomography revealed no evidence of bliary stones, but EUS exhibited minilithiasis in the gallbladder. After laparoscopic cholecystectomy, no further events of pancreatitis happened.
