The marvel of the liver is not just its capacity for regeneration but also the swift pace at which it regenerates. A study by a Mumbai hospital has revealed that a transplanted liver in a recipient, and the remnant liver in a donor, grows back to its normal size much faster than has been previously believed.
Doctors at the Kokilaben Dhirubhai Ambani Hospital (KDAH) have found that liver regeneration is nearly complete by three weeks, and does not take three months as most conventional medical textbooks suggest. The Andheri hospital that runs a living-donor transplant program busted the myth by tracking the regeneration of liver in 11 recipients and six donors who had undergone transplants between March and November 2013.
The liver is the only organ in the human body that can regrow to near normal size from as little as 25%. In living-donor liver transplantation, a part of the donor's liver is used to replace the damaged or cancerous liver of the recipient patient. Both the remaining liver of the donor and the part transplanted into the patient grow back to full size.
