Doctors at a hospital in Delhi constructed a liver in the body of an obese man by joining two liver lobes donated by two of his family members, as the portion of liver donated by one was not sufficient.
Sameer Mitra, 46, weighed 93kg. Doctors removed 220 grams of the liver lobe from his brother-in-law, and another 550gm from his brother-in-law's wife to conduct the life-saving procedure. Doctors say such cases are becoming common due to rise in obesity and liver failure, which in many cases are correlated.
AdvertisementIn some cases like in that of Mitra multiple donations are required to conduct transplant on an obese patient. The recovery, revival of the transplanted organ and overall survival in morbidly obese patients who undergo liver transplant is also less successful as compared to non-obese.
Mitra suffered from a cryptogenic liver disease for three years which necessitated transplant. Mitra's brother-in-law and his wife blood group matched that of Mitra's and they came to donate. Only a small part of liver-left lateral lobe-from his brother-in-law was taken because he himself is a kidney patient."
Due to the complications involved only few such surgeries have been conducted in the country so far. Nearly 30% of patients requiring liver transplant are obese or overweight. At least 10% are turned away either due to unavailability of donors in the family or the risks involved in surgery," said a surgeon.
"In case of cadaver donors, we can take out as much of liver as required. But due to fatty liver disease there are many instances where liver harvested from a brain-dead donor is wasted as it is too fatty for transplantation. These grafts do not grow and the risk of rejection is very high," said a senior doctor.
