摘要:

目的 初步探索三维可视化技术对结直肠癌患者施行腹腔镜 D3 根治术的临床应用价值。 方法 回顾分析 2019 5 月至 2021 3 月在东莞市人民医院接受腹腔镜结直肠癌 D3 根治术的 40 例患者 的临床资料,患者术前均行薄层增强 CT 检查后运用商业重建软件进行三维可视化重建并指导实际手 结果 三维可视化重建模型清晰显示结肠形态和走向、肿瘤位置、各主要血管以及癌肿供血血管解 剖与变异,与实际手术探查符合率 100%,根据三维模型术前拟定的结直肠癌 D3根治术手术方案与实际手术方案符合率 100%。全组 40 例患者均顺利完成手术,无 1 例患者中转开腹手术。血管意外损伤数目 0,手术时间(162.1 ± 51.7)min,术中失血量(58.6 ± 46.3)mL;术后首次排气时间(51.7 ± 36.7)h,术后住 院时间(8.2 ± 6.5)d。术后出现并发症者 4 例,其中炎性肠梗阻 1 例,吻合口漏 1 例,淋巴漏 2 例,并发症发 生率为 10.0%,所有并发症均保守治疗治愈出院,无术中及术后死亡病例。术后病理结果显示:肿瘤直径 5.1 ± 3.8)cm,淋巴结(包含系膜内癌结节)清扫数目(28.8 ± 39.1)枚,其中阳性淋巴结数目(3.9 ± 2.5)枚; 肿瘤分期: 4 例,Ⅱa 8 例,Ⅱb 5 例,Ⅲa 15 例,Ⅲb 5 例,Ⅲc 3 例。结论 三维可视化技术 在明确肿瘤供血动脉及其血管变异基础上,不但能提高手术效率和安全性,更能在符合肿瘤学基础上施 行精准的腹腔镜结直肠癌D3根治术。

Abstract:

Objective To preliminary explore the clinical value of three⁃dimensional visualization technol⁃ ogy for the laparoscopic D3 radical resection of colorectal cancer. Methods The clinical data of forty patients with colorectal cancer undergoing laparoscopic D3 radical operation in Dongguan Municipal People′s Hospital from May 2019 to December March 2021 were analyzed retrospectively. Before the operation,all patients underwent enhanced CT examination and then used commercial reconstruction software to perform 3D visualization reconstruction and guide the actual operation. Results The three⁃dimensional visualization model clearly showed the shape and direction of the colon,the location of the tumor,the anatomy and variation of the main blood vessels and the blood vessels supplying the cancer,and showing a coincidence rate of 100% with the actual surgical exploration. The D3 radical resection of colorectal cancer is formulated based on the three⁃dimensional model before the operation. The coincidence rate with the actual surgical plan was 100%. All the 40 patients completed operations successfully and no patient was converted to open surgery. The unexpected injury of blood vessel did not happen. The mean operative time was(162.1 ± 51.7)min with a mean estimated blood loss of(58.6 ± 46.3)mL. The mean time of first flatus was(51.7 ± 36.7)h and the postoperative hospital stay was(8.2 ± 6.5)d. The postoperative complications appeared in 4 patients,including one of inflammatory bowel obstruction,one of anastomotic leakage and two of lymphatic fistula,the complication rate was 10.0% ,and they were all cured with conservative treatments. The mean number of harvested lymph node was(28.8 ± 39.1),among which(3.9 ± 2.5)was positive. TNM staging:Stage Ⅰ4 cases,Stage Ⅱa 8 cases,Stage Ⅱb 5 cases,Stage Ⅲa 15 cases,Stage Ⅲb 5 cases,Stage Ⅲc 3 cases. Conclusions On the basis of clarifying tumor blood supply arteries and their vascular variations,3D visualization technology can not only improve the efficiency and safety of surgery,but also perform accurate laparoscopic D3 radical resection of colorectal cancer on the basis of oncology.
