title: Role of hand-assisted laparoscopic surgery in living-donor right liver harvest.
abstract: OBJECTIVE
  The cosmetic aspects of abdominal skin incisions are a matter of concern for both live liver donors and surgeons. We performed a prospective comparative study on the use of minilaparotomy to perform right liver graft harvests with and without hand-assisted laparoscopic surgery (HALS).
  
  
  METHODS
  Young donors were indicated for surgery using minilaparotomy with or without HALS. In the non-HALS group (n = 20), a 10-12-cm-long right subcostal incision was used for right liver graft harvest. In the HALS group (n = 20), an 8-cm-sized right subcostal incision was used for hand assistance and 3 laparoscopic holes made for manipulation. The retrohepatic inferior vena cava (IVC) was initially laparoscopically dissected while using air inflation. The skin incision was extended to 10-12 cm, and then hilar dissection and hepatic transection were performed through the skin incision.
  
  
  RESULTS
  In all 40 donors in the study cohort, safe uneventful harvesting of the right liver grafts was successfully achieved through the minilaparotomy incisions. The HALS group required an additional 30 minutes for laparoscopic preparation and dissection compared with the non-HALS group. HALS facilitated retrohepatic IVC dissection, and the remaining part of the surgery was the same as that for minimal-incision surgery. The minimal skin incision for the delivery of the liver from the abdomen was an average 10 cm for grafts <500 g and 12 cm for grafts ≥700 g. Compared with the patient profiles, there were no differences regarding donor age, body mass index, graft weight, intraoperative blood loss, postoperative increase in peak liver enzymes, total hospital stay, and incidence of postoperative complications.
  
  
  CONCLUSIONS
  HALS facilitates the performance of donor hepatectomy with the use of a minimal incision, which probably allows for a wider selection of living donors.
