Optimization of donor selection as well as institutional experience is imperative to improve the surgical outcome. Even though donor hepatectomy was associated with relatively higher complication rate, most complications showed low-grade severity which could be corrected by interventional therapies.

Although the procedure requires a lot of technical expertise added to the skill of liver surgery, single-port laparoscopic liver resection for hepatocellular carcinoma seems a feasible approach in a variety of well-selected cases. In spite of the demanding nature of the procedure and the requirement of better instrumentation for single-port laparoscopic surgery, the results seem to compare favorably with conventional laparoscopic surgery and open surgery.

Orphanin FQ/nociceptin (NOC) has been reported to regulate dopaminergic neurotransmission in rewarding pathway, and to suppress the development of conditioned place preference (CPP) induced by certain addictive drugs. In this study, we investigated the effect of NOC on CPP induced by repeated administration of methamphetamine (MAP) in rats. Repeated administration of MAP (1 mg/kg, i.p.) induced substantial CPP. MAP-induced CPP was completely suppressed by NOC (10 nmol, i.c.v.). Pretreatment with [Nphe1]nociceptin(1-13)NH2 (50 nmol, i.c.v.), an antagonist of the NOC receptor, antagonized the suppressive effect of NOC on MAP-induced CPP. These results suggest that NOC blocks MAP-induced CPP by activation of the NOC receptor.
