Spontaneous common bile duct (CBD) perforation leading to biliary peritonitis is a rare entity in children. It is an unusual cause of acute abdomen and is potentially fatal. Preoperative diagnosis is rare. A 10-year-old girl was referred from a private hospital after laparotomy for acute abdomen. Intraoperatively, bile was found in the peritoneal cavity which was drained, and the patient was referred to Topiwala National Medical College. Endoscopic retrograde cholangiopancreaticography (ERCP) and stenting was done. The stent was removed after 8 weeks, and the girl is doing well during follow-up.
