Gallbladder remnant: A potential source for biliary stones postcholecystectomy; a case report in a child with sickle cell disease

Stone formation in a gallbladder remnant is a rare postcholecystectomy complication. This report describes the case of gallstones in a gallbladder remnant of an adolescent with sickle cell disease (SCD) years after laparoscopic cholecystectomy. A 15‐year‐old female with SCD presented to our gastroenterology clinic with concerns of recurrent choledocholithiasis despite cholecystectomy 2 years before presentation. About 4 months before presentation to our clinic, she was evaluated at the referring physician's emergency department for recurrent severe abdominal pain of 1 month duration. After admission to the hospital, common bile duct stones were seen on magnetic resonance cholangiopancreatography (MCRP) imaging and subsequently removed via endoscopic retrograde cholangiopancreatography (ERCP). On review of her MRCP and ERCP at our hospital, a remnant of gallbladder containing multiple stones was identified. She subsequently underwent a laparoscopic resection of the gallbladder remnant. Clinicians should consider biliary duct imaging in children with biliary colic following cholecystectomy, especially those with history of chronic hemolysis.
