Efficacy of multislice computed tomography for gastroenteric and hepatic surgeries

Figure 1 A case of sigmoid colon cancer who underwent a laparoscopic sigmoidectomy. A: Three-dimensional volume-rendered CT (3DCT) angiographic reconstructions show the IMA and its branches; B: The intraoperative findings similar to the preoperative visualization of the IMA were obtained. White arrowheads show the sigmoidal artery.

Figure 2 A: 3DCT image of the LCA is partially indistinct (two arrowheads); B: Swollen lymph nodes adhered to the LCA (two arrowheads).

Figure 3 A: A slight deformity of the SRA was showed by 3DCT; B: In intraoperative findings, a slight deformity of the SRA was comfirmed.

Figure 4 3DCT scans showed the CHA diverging from the SMA (A) and the RHA branching from the SMA (B).

Figure 5 A case of hepatocellular carcinoma who could not undergo angiography due to severe arteriosclerosis. Preoperative visualization of the HA was obtained.

Figure 6 The follow-up patient who underwent right hemicolectomy for ascending colon cancer: A: In the axial view, it was difficult to distinguish whether low density area (LDA) in the lateral segment of the liver was dissemination or liver metastasis; B: The LDA was diagnosed as dissemination by MPR image (a sagittal view).
