Key Points1 Pancreatitis in children remains an uncommon clinical phenomenon. 2 Increased use of parenteral nutrition and increased survival from extended episodes of sepsis is likely to lead to increased episodes of cholelithiasis, cholecystitis and choledocholithiasis. 3 Gallstone pancreatitis is likely to become a more common cause of severe abdominal pain in children.tinued to vomit non-bile-stained material but tolerated increasing feeds over the first 3 days of admission. Repeat investigations on day 3 revealed a reduction in the white blood cell count (13.6) but a rise in total bilirubin (46, normal 0-15 µmol/L), conjugated bilirubin (26, normal 0-10 µmol/L) and alanine aminotransferase (316, normal <55 IU/ L). The ALP (327, normal 100-350 IU/L) and GGT (215) were at the upper level of normal limits. Blood cultures grew Staphylococcus epidermis epidermis, resulting in a change in antibiotics to vancomycin and cefotaxime. The mid-stream urine was clear. Vomiting and poor oral intake continued into days 4 and 5 and further investigations on day 4 revealed a raised amylase (256, normal 36-128 IU/L) and a normal lipase (19, 8-57 IU/L).Upper abdominal ultrasonography revealed a 'thin-walled gallbladder with no gallstones within, intra-and extra-hepatic bile duct dilatation and a common bile duct (CBD) measuring 4.4 mm in diameter'. The pancreas was not visualised due to overlying bowel. As the child's clinical situation was not improving, he was transferred to a tertiary paediatric hospital for surgery. Open cholecystectomy was performed to facilitate both a cholangiogram and CBD exploration. Macroscopically the gall bladder was thick-walled but allowed a cholangiogram catheter to be introduced, revealing two stones in the proximal CBD but no stones in the gall bladder itself. A separate cystic duct incision was required for introduction of a 4 Fr Fogarty embolectomy catheter and withdrawal of both stones. A further cholangiogram revealed no further filling defects. Cholecystectomy was performed because of the thickened gall bladder and the risk of cystic duct stenosis. The pancreas was not visualised at the time of operation. Subsequent histological analysis of the gall bladder revealed signs of both 'acute and chronic inflammation'. The patient remains well almost 4 years post-surgery.
