[Study on the clinical application of abdominal medical image proceeding system in extended hepatectomy].
OBJECTIVE
To study the applied value of abdominal medical image proceeding system (AMIPS) in extended hepatectomy.


METHODS
Sixty-four-slice spiral computer tomography (CT) scan data of 32 cases treated from September 2007 to July 2009 (15 male, 17 female; mean age 52 years old) with liver tumor was collected, among which there were 9 cases with huge liver tumor. The data was imported into AMIPS for sequence segmenting and three-dimensional (3D) reconstruction. The reconstructed models were imported into virtual system of AMIPS for digital hepatic segment partition and extended hepatectomy analysis for huge liver tumor of 9 cases. According to the calculated data, suitable modus operandi were selected.


RESULTS
In the AMIPS, the 3D models could show the relationships between the lesions to the surrounding tissue more intuitively and the type of blood supply. Digital hepatic segment partition made localize lesions more exactly. It was possible to hepatic segmentectomy and analysis of extended hepatectomy by calculating the relative volume of hepatic segment of huge liver tumor. Huge liver tumor of 9 cases performed different modus operandi, including two cases with right hemi hepatectomies, five cases with hepatic segmentectomy of S6 and S7, two cases with hepatic segmentectomy of S5-7 and part of the S8. There were margin-free tumor cells and no complications such as liver failure in all cases. The average hospitalization time was 21 d.


CONCLUSIONS
AMIPS is helpful in the diagnosis of hepatic disease and in the optimizing surgical plans which can decrease surgical risk and help prevent postoperative hepatic failure.
