<unk>  or hepatic transplantation is the replacement of a diseased<unk>  with the healthy<unk>  from another person (allograft).<unk>  is a treatment option for end-stage<unk>  disease and acute<unk>  failure, although availability of donor organs is a major limitation. The most common technique is orthotopic transplantation, in which the native<unk>  is removed and replaced by the donor organ in the same anatomic position as the original<unk> . The surgical procedure is complex, requiring careful harvest of the donor organ and meticulous implantation into the recipient.<unk>  is highly regulated, and only performed at designated transplant medical centers by highly trained transplant physicians and supporting medical team. The duration of the surgery ranges from 4 to 18 hours depending on outcome. Favorable outcomes require careful screening for eligible recipient, as well as a well-calibrated<unk> or cadaveric donor match.
