ABSTRACT
BACKGROUND: The purpose of the present study was to determine the etiology, management, and outcome of acute pancreatitis (AP) in children in an endemic area of hepatobiliary ascariasis (HBA). METHODS: This was a prospective, hospital-based study over a 9-year period that included 156 children younger than 12 years of age who had a diagnosis of AP. RESULTS: Of the 156 patients, 71 were boys and 85 were girls with a mean age of 8.4 ± 1.5 years (range 3-12 years). The various factors contributing to AP were biliary ascariasis in 93 cases (60 %), gallstones 16 (10 %), trauma 5 (3 %), choledochal cyst 4 (3 %), impacted bile duct stone 3 (2 %), and gallbladder sludge 2 (1 %). Idiopathic group 33 cases (21 %). Diagnosis was based on clinical picture, abdominal ultrasonography, and elevated serum amylase level. Pancreatitis was mild in 113 (72 %) patients and severe in 43 (28 %). With conservative therapy, 123 patients (79 %) improved, whereas the remaining 33, who had intractable abdominal pain, cholangitis, or worsening cholecystitis, underwent emergency endoscopic retrograde cholangiopancreatography for removal of worms (26 patients) and stones in the bile duct (7 patients). Bile duct stones were extracted in all 7 patients with that condition, and worms were extracted from 23 of the 26 patients with ascariasis. Emergency surgery was performed in five patients. Three patients died. Pancreatitis recurred in 16 patients due to HBA. CONCLUSIONS: Pancreatitis is not uncommon in children. Ascariasis is a leading cause of AP in endemic areas. Patients usually respond to conservative management, but endoscopic treatment is effective. Surgery is rarely required.
