LigaSure versus monopolar cautery for recipient hepatectomy in liver transplantation: a propensity score-matched analysis.

ABSTRACT

BACKGROUND: Recipient hepatectomy during liver transplantation (LT) is one of the most challenging aspects of surgery due to the possibility of massive bleeding. This study aimed to compare and analyze the effectiveness between LigaSure and monopolar cautery in recipients. METHODS: We reviewed 187 recipients who underwent LT from March 2019 to June 2020. We compared the surgical outcomes of the 69 recipients who underwent recipient hepatectomy with LigaSure (LigaSure group) and 118 recipients who underwent with monopolar cautery. Propensity score matching (PSM) was performed using the nearest-neighbor method at a ratio of 11 based on 14 baseline characteristics and possible factors that influence postoperative bleeding. RESULTS: A total of 187 adult recipients were reviewed retrospectively. In the propensity score-matched analysis, The rates of bleeding and infectious complication were significantly lower in the LigaSure group than in the monopolar cautery group (3/69, 4.35% versus 13/69, 18.8%; P=0.015 and 1/69, 1.45% versus 9/69, 13.0%; P=0.017). The length of postoperative hospital stay was shorter in the LigaSure group (mean 23.1±16.1 versus 39.6±58.2 days; P=0.024). CONCLUSIONS: Recipient hepatectomy with LigaSure is associated with a short hospital stay due to low re-operation rates, postoperative bleeding, and secondary infection related to bleeding.
