Abstract:
Objective:To explore whether CT image post-processing software can accurately measure (associating liver partition and portal vein ligation for staged hepatectomy, ALPPS) related (future liver remnant, FLR).Methods:Clinical data of 9 liver cancer patients undergoing ALPPS were retrospectively analyzed in the Second Affiliated Hospital of Air Force Military Medical University from Mar 2015 to May 2019. All cases were divided into 2 groups by measurement: CT′s image post-processing software, or Myrian software. Two groups were compared with each other by paired t-test. Results:FLR from group CT′s image post-processing software was larger than that by Myrian software, there was statistical difference ( t=2.512, P=0.019). The mistakes of FLR measurements by the radiologist using CT′s image post-processing software couldbe caused by: (1)Lacking theoretical knowledge of liver surgery; (2) Adding devitalized tissue of hepatic section into future liver remnant; (3) Concept confusion about liver anatomy; (4) Lack of precision measurement. Conclusions:The inaccuracies generated during the ALPPS related future liver remnant measurements in CT′s image post-processing technique are all caused by human factors. These problems could be solved if the radiologist who operates 3D reconstruction receives liver surgery training or works with liver surgeons.
