Abstract

Objectives: Liver transplant is the definitive treatment for liver failure of various causes. There are various operation methods, of which the conventional approach is most frequently performed. In the conventional technique, 4 anastomoses are required, and different subtleties in these techniques are known to cause different rates of complications. We assessed the outcome of a simple separate (ie, interrupted) suture technique compared with a the continuous suture technique in 194 patients. Materials and Methods: There were 194 patients included in this single-center, controlled study. The exclusion criteria were patients who died during the surgical procedure and patients with incomplete medical records. The data recorded were age, sex, past medical history of liver disease, tobacco use, comorbidities, and whether the liver transplant was for the first time or retransplant. All patients included in this study were recipients of liver transplants from deceased donors. The patients were categorized as those who received either simple sutures (n = 16) or continuous sutures (n = 178). The continuous suture operations were performed first, and the simple suture operations were performed at a later time (ie, the 2 groups were temporally separated). The results included the duration of surgery, hepatic artery thrombosis rate, hepatic artery stenosis rate, 2-year survival, and further complications. Results: No evidence of hepatic artery thrombosis or hepatic artery stenosis was observed in the study groups. The duration of surgery was equal in both groups. The 2-year mortality rate was significantly higher in the simple suture group. Conclusions: The continuous suture method seems to be accompanied by a similar duration of operation and rate of complications compared with the simple suture process. © Baskent University 2023.
