- Abstract
Purpose: The aim of this retrospective study was to evaluate a revised classification system for predicting the difficulty of laparoscopic partial liver resection. Methods: Patients who had undergone initial laparoscopic partial liver resection for a solitary lesion from January 2012 to February 2021were classified into two groups according to the type of procedure performed, "scooping-out" versus "cutting." The participants were then further divided into "small" and "large" subgroups according to the tumor's depth and diameter. Finally, they were categorized into two groups, namely "standard" and "advanced." Operative outcomes were compared between the two groups and the proposed revised system for classifying difficulty of laparoscopic partial liver resection compared with the existing scoring system. Results: Of the 65 procedures assessed, 40 were categorized as standard and 25 as advanced. Tumor size (P < 0.001), operation time (P < 0.001), volume of intraoperative blood loss (P = 0.001), rate of the Pringle maneuver (P = 0.044), and resected liver weight (P < 0.001) were significantly greater in the advanced than in the standard group. Differences in operation time and intraoperative blood loss were not identified by the existing difficulty scoring system. Conclusion: The proposed revised classification is useful for predicting the difficulty of laparoscopic partial liver resection.
