目的:观察直肠癌腹腔镜全直肠系膜切除术后吻合口复发患者的CT纹理信息，分析纹理参数评估腹腔镜全直肠系膜切除术后吻合口复发的价值。方法:抽取2017年1月至2020年1月河南科技大学附属许昌市中心医院收治的90例直肠癌患者为研究对象。入组患者均于直肠癌腹腔镜全直肠系膜切除术后进行为期18个月的随访，其中吻合口复发者22例纳入复发组，未复发者68例纳入未复发组。比较两组患者的CT纹理参数，分析CT纹理参数评估腹腔镜全直肠系膜切除术后吻合口复发的价值。结果:与未复发组比较，复发组患者CT纹理分析参数中均值、峰度、熵、短径水平均较高，差异有统计学意义(n P1，n P<0.05)；绘制受试者工作特征曲线发现，直肠癌患者CT纹理分析参数(均值、峰度、熵、短径)预测术后吻合口复发的曲线下面积分别为0.903、0.746、0.889、0.864，均有一定的预测价值，最佳截断值分别取158.720、4.855、6.385、4.500 mm时可以获得最佳预测效能。n 结论:直肠癌患者CT纹理分析参数对腹腔镜全直肠系膜切除术后吻合口复发风险有一定的评估价值，临床可通过直肠癌患者CT纹理分析参数评估术后吻合口复发风险，并据此给予针对性的干预措施，降低术后吻合口复发率。“,”Objective:To observe the CT texture information of patients with anastomotic recurrence after laparoscopic total rectal mesenteric resection for rectal cancer, and analyze the value of CT texture information in evaluating anastomotic recurrence after laparoscopic total mesenteric resection.Methods:Ninety patients with rectal cancer admitted to Xuchang Central Hospital Affiliated to Henan University of Science and Technology from January 2017 to January 2020 were selected as the research objects. All patients were followed up for 18 months after laparoscopic total mesenteric resection for rectal cancer. Among them, 22 cases with anastomotic recurrence were included in the recurrence group, and 68 cases without recurrence were included in the non recurrence group. The CT texture parameters of the two group were compared, and the value of CT texture information in evaluating anastomotic recurrence after laparoscopic total mesenteric resection was analyzed.Results:Compared with non recurrence group, the mean, kurtosis, entropy and short diameter of CT texture analysis parameters in the recurrence group were higher, and the difference was statistically significant (n P 1,n P<0.05). It was found that the areas under the receiver operating characteristic curve of CT texture analysis parameters (mean, kurtosis, entropy and short diameter) for predicting postoperative anastomotic recurrence in patients with rectal cancer were 0.903, 0.746, 0.889 and 0.864, respectively, all of which had certain prediction value. The best prediction efficiency can be obtained when the cut-off values were 158.720, 4.855, 6.385 and 4.500 mm, respectively.n Conclusions:CT texture analysis parameters of rectal cancer patients have a certain evaluation value for the risk of anastomotic recurrence after laparoscopic total mesenteric resection. In clinical, the risk of postoperative anastomotic recurrence can be evaluated by CT texture analysis parameters of rectal cancer patients, and targeted intervention measures can be given to reduce the rate of postoperative anastomotic recurrence.
