Application of Embedding Hepaticojejunostomy in Children with Pancreaticobiliary Maljunction Without Biliary Dilatation

Background: To investigate the effect of embedded hepaticojejunostomy in children with pancreaticobiliary maljunction (PBM) without biliary dilatation. Materials and Methods: The clinical data of 10 patients with nondilated PBM from February 2017 to July 2020 were retrospectively analyzed. Perioperative liver function indexes were compared. Results: All patients were diagnosed by magnetic resonance cholangiopancreatography (MRCP) combined with intraoperative cholangiography. There were 5 cases of Komi type I and 5 cases of type II; the diameter of the common bile duct was 4-9 mm (median: 6 mm); and the length of the common channel was 5-15 mm (median: 9.25 mm). The procedure for one patient with common duct stones was converted to open surgery. Laparoscopic cholecystectomy, common bile duct resection, and embedded hepaticojejunostomy were successfully performed in all 10 cases. The average operation time was 225 +/- 96.64 min, and the intraoperative blood loss was 2-5 mL. The mean time to oral intake was 3.5 +/- 1.65 days (range: 2-5 days), and the mean hospitalization duration was 6.2 +/- 2.44 days (range: 5-8 days). The differences in liver function indexes in the perioperative period were statistically significant (P < .05). The patients were followed-up for 13 to 54 months (median: 40 months). All patients grew well and there was no bile duct dilatation, calculus, or cirrhosis on B-ultrasound examinations. Conclusions: The clinical manifestations of nondilated PBM are often concealed, and preoperative MRCP was important for obtaining a diagnosis. Laparoscopic cholecystectomy, common bile duct resection, and embedded hepaticojejunostomy are feasible for treating nondilated PBM.
