Evaluation of accuracy of laparoscopic liver mono‐segmentectomy using the Glissonian approach with indocyanine green fluorescence negative staining by comparing estimated and actual resection volumes: A single‐center retrospective cohort study

Background/Purpose Laparoscopic liver mono‐segmentectomy (LLMS) may improve patient outcomes, but it is difficult and its accuracy and safety are unknown. We evaluated the accuracy of LLMS using Glissonian approach with indocyanine green fluorescence (ICG) negative staining. Methods Seventy‐four pat...

Description
Summary:Background/Purpose Laparoscopic liver mono‐segmentectomy (LLMS) may improve patient outcomes, but it is difficult and its accuracy and safety are unknown. We evaluated the accuracy of LLMS using Glissonian approach with indocyanine green fluorescence (ICG) negative staining. Methods Seventy‐four patients eligible for LLMS except for segment 1 were enrolled. Preoperative three‐dimensional CT‐based surgical simulation was used to determine estimated liver resection volume (ELRV), which was compared with modified actual liver resection volume (ALRV) obtained from actual liver resection mass. The LLMS accuracy was also evaluated based on operator's experience (attending surgeon [AS] or trainee surgeon [TS]). Results Estimated liver resection volumes significantly correlated with ALRVs (r = .82) in all cases. Moreover, TS‐conducted LLMS also showed acceptable difference between ELRV and ALRV compared with AS‐conducted LLMS. There were no intergroup differences in estimated blood loss, operation time, time of Pringle maneuver, postoperative complications, and length of postoperative hospitalization (P
