Laparoscopic Liver Resection Using a Silicone Band Retraction Method (With Video).

ABSTRACT

BACKGROUND: The success of laparoscopic liver resection (LLR) depends on stable and full exposure of the parenchymal transection plane. We evaluated the efficacy of LLR using a silicone band retraction method for lesions in the anterolateral and posterosuperior segments. METHODS: We retrospectively analyzed 189 consecutive patients who had undergone LLR in our hospital between July 2010 and July 2020. They were divided into 2 groups according to whether LLR was performed before (conventional group; n=64) or after (silicone band group; n=125) the introduction of the silicone band retraction method. RESULTS: The silicone band group demonstrated significantly less blood loss than that by the conventional group. The mean operative time and the hospital stay in the silicone band group were obviously shorter than that in the conventional group. The open conversion rate and the major complication rate were significantly lower in the silicone band group than that in the conventional group. CONCLUSION: The silicone band retraction method is a useful approach that results in a safe LLR.
