RESUMEN
@#Peritonitis caused by biliary tract perforation is unsual. After other causes, such as trauma, biliary tract stone, cyst of choledocal duct, can be rule out, we should reconsider leakage or rupture of biliary tract. We report a 3 years old boy was administered to emergency room with abdominal distended, vomiting and diarrhea, low-grade fever, and diffuse abdominal pain. There’s no history of jaundice and abdominal pain before, neither trauma. Sign of peritonitis were found. The patient underwent laparotomy, perforation at common bile duct was found without any other disease. Intra abdominal drain was placed near the leak and primary repair was done with tube drain inside the duct. The pastient discharged after 8 days hospitalized uneventful.
