Abstract

Aim: To determine the efficacy of multislice CT for gastroenteric and hepatic surgery.

Methods: Dual-phase helical computed tomography was performed in 50 of 51 patients who underwent gastroenteric and hepatic surgeries. Twenty-eight, eighteen and four patients suffering from colorectal cancer, gastric cancer, and liver cancer respectively underwent colorectal surgery (laparoscopic surgery: 6 cases), gastrectomy, and hepatectomy. Three-dimensional computed tomography imaging of the inferior mesenteric artery, celiac artery and hepatic artery was performed. And in the follow-up examination of postoperative patients, multiplanar reconstruction image was made in case of need.

Results: Scans in 50 patients were technically satisfactory and included in the analysis. Depiction of major visceral arteries, which were important for surgery and other treatments, could be done in all patients. Preoperative visualization of the left colic artery and sigmoidal arteries, the celiac artery and its branches, and hepatic artery was very useful to lymph node dissection, the planning of a reservoir and hepatectomy. And multiplanar reconstruction image was helpful to diagnosis for the postoperative follow-up of patients.

Conclusion: Three-dimensional volume rendering or multiplanar reconstruction imaging performed by multislice computed tomography was very useful for gastroenteric and hepatic surgeries.

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.

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

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

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).
