[Comparative study of three kinds of outflow tract reconstruction of hepatic veins in piggyback liver transplantation].
OBJECTIVE
To study the effects of 3 different operational patterns of piggyback liver transplantation (PBLT) used to reconstruct backflow of hepatic veins.


METHODS
Sixty-three operations of PBLT were performed on 59 patients with terminal hepatic diseases after three operational patterns: EEAT [the suprahepatic inferior vena cava (sup-H-IVC) of donor is anstomosed with the plasticized hepatic vein of recipient end-to-end, also called standard PBLT, SPBLT] in 17 cases, ESAT (the sup-H-IVC of donor is anastomosed with the sup-H-IVC of recipient end-to-side) in 12 cases, and SSAT [the retrohepatic IVC (RHIVC) of donor is anastomosed with the RHIVC of recipient side-to-side] in 32 cases, the latter two patterns being called ameliorative PBLT (APBLT) jointly. The effects were analyzed.


RESULTS
Complications, such as backflow obstruction of hepatic vein and delayed recovery of liver function, were observed in the EEAT and ESAT groups, but not in the SSAT group.


CONCLUSIONS
The SSAT pattern of PBLT is easy to perform and advantageous to avoid the technical maladies of the other 2 patterns and postoperative complications, and provides assurance of recovery after operation.
