Three-dimensional computer reconstruction in hemihepatectomy / 中华肝胆外科杂志

ABSTRACT

Objective:To study preoperative three-dimensional computer reconstruction in hemihepatectomy.Methods:The clinical data of patients who underwent hemihepatectomy at Affiliated Provincial Hospital of Anhui Medical University from January 2017 to August 2019 was retrospectively analyzed. Of 68 patients, there were 33 males and 35 females. The average age was 60.1 years. Based on whether the patients underwent preoperative three-dimensional computer reconstruction, these patients were divided into the three-dimensional group ( n=30) and the control group ( n=38). The coincidence rates of preoperative diagnosis by imaging, vascular types and preoperative in relation to intraoperative findings between the two groups were compared. Results:Using intraoperative findings as the gold standard, the coincidence rates of preoperative imaging diagnosis of cholelithiasis, hilar cholangiocarcinoma and intrahepatic space occupying lesions were 96.7% (29/30) in the three-dimensional group, and 94.7% (36/38) in the control group. There was no significant difference between the two groups ( P>0.05). Using intraoperative or anatomic specimens findings, the coincidence rates of preoperative evaluation of portal vein and bile duct in the three-dimensional group were 93.3% (28/30) and 96.7% (29/30) respectively. The corresponding rates for the control group were 73.7% (28/38) and 79.0% (30/38) respectively. Furthermore, the coincidence rates of liver volume were 96.7% (29/30) in the three-dimensional group and 79.0% (30/38) in the control group. Assessments on portal vein, bile duct and liver volumes were significantly better in the three dimensional group than the control group ( P<0.05). Conclusion:Preoperative three-dimensional computer reconstruction better diagnosed hilar space occupying lesions and hepatolithiasis, and more accurately delineated vascular courses. All these had important clinical impact on hemihepatectomy.
