First right lobe living-donor hepatectomy after sleeve gastrectomy

Obesity presents one of the leading causes of many chronic liver disorders and injuries. Nowadays, non-alcoholic steatohepatitis (NASH) demonstrates a challenging issue for the global health system. NASH can progress to life-threatening conditions such as cirrhosis and hepatocellular or cholangio carcinoma. Currently, NASH cirrhosis is a major indication for liver transplant (LT). We present the case of a 37 year-old male who has lost 74 kg after undergoing successful laparoscopic sleeve gastrectomy (SG) four years ago. Recently, he underwent right hepatectomy in the course of living-donor liver transplantation for his sick father in our clinic. Before the SG was conducted four years ago, his weight was at 157 kg and his Body Mass Index (BMI) at 49 kg/m 2 . At that time, Ultrasound examination showed severe fatty liver changes and intraoperative inspection of the liver was consistent with that observation. At the time of surgery, he weighed 83 kg and his BMI was at 27 kg/m 2 . An effective weight reduction after bariatric surgery might protect NASH patients from further deterioration of their medical condition. To our knowledge, we report the first successful case of a right lobe living-donor hepatectomy in a patient who previously underwent successful laparoscopic sleeve gastrectomy (LSG).
