Abstract

Background: The objective of this study was to assess the application value of SOMATOM Force computed tomography (CT) in assisting the preoperative localization of colorectal cancer resection surgery.

Method: Retrospectively, the medical data of 120 inpatients with colorectal cancer were collected. The Kappa consistency test was used to evaluate diagnostic consistency in the localization and staging of colorectal cancer. The diagnostic value of preoperative SOMATOM Force CT detection was analyzed.

Results: In 120 colorectal cancer patients, the accuracy of SOMATOM Force CT for preoperative localization, T staging, and N staging of colorectal cancer were 91.7% (kappa = 0.837), 88.3% (kappa = 0.772) and 91.7% (kappa = 0.773), respectively. Among 45 rectum cancer patients, there were 19 positive cases with circumferential resection margin involvement, and the accuracy of SOMATOM Force CT detection was 86.7% (kappa = 0.767). The sensitivity, specificity, positive predictive value, and negative predictive value of SOMATOM Force CT detection in evaluating the circumferential resection margin involvement of rectum cancer were 78.95%, 96.15%, 93.75%, and 86.21%, respectively.

Conclusions: There was an important application value of SOMATOM Force CT in assisting the preoperative localization and tumor staging of colorectal cancer resection surgery. There was a good diagnostic value of preoperative SOMATOM Force CT detection in evaluating the circumferential resection margin involvement of rectum cancer.

SOMATOM Force 计算机断层扫描在协助结直肠癌切除手术术前定位中的应用价值。

研究背景本研究旨在评估 SOMATOM Force 计算机断层扫描（CT）在协助结直肠癌切除手术术前定位方面的应用价值：方法：回顾性收集 120 名结肠直肠癌住院患者的医疗数据。方法：回顾性收集 120 例大肠癌住院患者的医疗资料，采用 Kappa 一致性检验评价大肠癌定位和分期的诊断一致性。分析了术前 SOMATOM Force CT 检测的诊断价值：在 120 名结直肠癌患者中，SOMATOM Force CT 对结直肠癌术前定位、T 分期和 N 分期的准确率分别为 91.7%（kappa = 0.837）、88.3%（kappa = 0.772）和 91.7%（kappa = 0.773）。在 45 例直肠癌患者中，有 19 例阳性病例周缘切除边缘受累，SOMATOM Force CT 检测的准确率为 86.7%（kappa = 0.767）。SOMATOM Force CT 检测评估直肠癌周缘切除边缘受累的敏感性、特异性、阳性预测值和阴性预测值分别为 78.95%、96.15%、93.75% 和 86.21%：SOMATOM Force CT 在协助结直肠癌切除手术的术前定位和肿瘤分期方面具有重要的应用价值。术前 SOMATOM Force CT 检测对评估直肠癌周缘切除边缘受累情况有很好的诊断价值。

期刊介绍： Minimally Invasive Therapy and Allied Technologies (MITAT) is an international forum for endoscopic surgeons, interventional radiologists and industrial instrument manufacturers. It is the official journal of the Society for Medical Innovation and Technology (SMIT) whose membership includes representatives from a broad spectrum of medical specialities, instrument manufacturing and research. The journal brings the latest developments and innovations in minimally invasive therapy to its readers. What makes Minimally Invasive Therapy and Allied Technologies unique is that we publish one or two special issues each year, which are devoted to a specific theme. Key topics covered by the journal include: interventional radiology, endoscopic surgery, imaging technology, manipulators and robotics for surgery and education and training for MIS.
