Repair of huge incisional hernias intentionally made during infantile living donor liver transplantation.

BACKGROUND AND PURPOSE: In some small infants who are transplanted with a large-for-size graft by living donor liver transplantation, an incisional hernia is intentionally made to decrease the tension on the graft. The procedure and timing for repair of this type of hernia were retrospectively evaluated. PATIENTS AND METHODS: Repair was carried out in 3 patients at 4 to 11 years after living donor liver transplantation. The preoperative, perioperative, and postoperative statuses were analyzed in each patient. RESULT: Fascial closure was possible in all 3 patients. In 2 patients, separation of a component of the rectus sheath or a lower part of the major pectoral muscle was required for approximation of the fascia. One recipient had transient bile leakage that was treated successfully. CONCLUSION: An intentionally made hernia should be as small as possible to facilitate easy primary closure at a later date. A procedure resembling the "clam-shell opening" method, which used a partly separated and extended sheet of the fascia, was feasible to avoid the requirement for an artificial mesh. Preschool ages may be suitable for easier approximation of the fascia.

Biliary reconstruction for infantile living donor liver transplantation: Roux-en-Y hepaticojejunostomy or duct-to-duct choledochocholedochostomy?

Hepaticojejunostomy is a standard biliary reconstruction method for infantile living donor liver transplantation (LDLT), but choledochocholedochostomy for infants is not generally accepted yet. Ten pediatric recipients weighing no more than 10 kg underwent duct-to-duct choledochocholedochostomy (DD) for biliary reconstruction for LDLT. Patients were followed up for a median period of 26.8 months (range: 4.0-79.0 months). The incidence of posttransplant biliary complications for DD was compared with that for Roux-en-Y hepaticojejunostomy (RY). No DD patients and 1 RY patient (5%) developed biliary leakage (P > 0.05), and biliary stricture occurred in 1 DD patient (10%) and none of the RY patients (P > 0.05); none of the DD patients and 5 RY patients (25%) suffered from uncomplicated cholangitis after LDLT (P > 0.05), and 1 DD patient (10%) and 2 RY patients (10%) died of causes unrelated to biliary complications. In conclusion, both hepaticojejunostomy and choledochocholedochostomy resulted in satisfactory outcome in terms of biliary complications, including leakage and stricture, for recipients weighing no more than 10 kg.
