Infections with pancreatic fluid or reflux may be a causal factor. Anomalies may develop in the formation of the bile pancretic ducts in which the pancreatic ducts coalesce with the bile ducts at a more proximal site beyond the ampulla vater, which may lead to reflux of pancreatic enzymes, also can ultimately cause damage to the duct wall and the occurrence of dilatation. This case report presents a boy 9-years-old, The patient is a referral of Karanganyar General Hospital, with complaints of lumps in the patient's stomach. Patients' complaints are also accompanied by yellow eyes. Vomiting history (+) white mucus, fever (+). Urine is yellow as thick as tea, feses is pale white.
