To determine the efficacy of multislice CT for gastroenteric and hepatic surgery.
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.
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.
Three-dimensional volume rendering or multiplanar reconstruction imaging performed by multislice computed tomography was very useful for gastroenteric and hepatic surgeries.
确定多层螺旋CT在胃肠及肝脏手术中的效能。
51例行胃肠及肝脏手术的患者中，50例接受了双期螺旋CT检查。分别有28例、18例和4例患有结直肠癌、胃癌和肝癌的患者接受了结直肠手术（腹腔镜手术：6例）、胃切除术和肝切除术。对肠系膜下动脉、腹腔干和肝动脉进行了三维CT成像。并且在术后患者的随访检查中，必要时进行多平面重建图像。
50例患者的扫描在技术上令人满意并纳入分析。对手术及其他治疗重要的主要内脏动脉在所有患者中均可显示。术前对左结肠动脉和乙状结肠动脉、腹腔干及其分支以及肝动脉的可视化对淋巴结清扫、贮袋规划和肝切除术非常有用。多平面重建图像有助于患者术后随访的诊断。
多层螺旋CT进行的三维容积再现或多平面重建成像对胃肠及肝脏手术非常有用。
