Right Lobe Liver Donation After Bariatric Surgery. A Case Series of 4 Living Donors

The increasing prevalence of obesity and need for bariatric surgery as well as the expanding use of living donors for liver transplantation means that potential donors could present with this surgical history. We present 4 cases of liver donors with previous bariatric surgery in our living donor liver transplant program.A retrospective descriptive analysis of patients with a bariatric surgery history who underwent right hepatectomy in our living donor liver transplant program is presented.Case 1: A 53-year-old man with body mass index (BMI) of 33 who underwent laparoscopic sleeve gastrectomy (LSG). Pretransplant BMI was 21.5. Case 2: A 46-year-old woman with a BMI maximum of 40.8 who underwent LSG and required conversion to Roux-en-Y gastric bypass. Pretransplant BMI was 35.1. Case 3: A 53-year-old woman with a BMI maximum of 31.6 who underwent LSG. Pretransplant BMI was 24.2. Case 4: A 38-year-old man with a BMI maximum of 41.5 who underwent Roux-en-Y gastric bypass 6 years before the hepatectomy. Pretransplant BMI was 29.4. No complications were observed. Average operative time was 367.5 minutes, with a hospital stay of 5.8 days and 100% graft survival to date.Utilization of selected donors with previous bariatric surgery appears to be a safe option and increases the donor pool.
