目的:探讨微粒子炭在指导直肠癌手术中淋巴结清除的临床意义。方法:采用前瞻性病例对照研究,患者随机分组:40 例直肠癌患者术前经肠镜局部注射微粒子炭后行直肠癌根治术,40例仅行常规直肠癌根治术作为对照组。所有病例记录清除的淋巴结数并做病理检查。结果:术中被黑染的淋巴结清晰可辨;注墨组平均每例清除淋巴结数为(24. 6±4. 2)个,对照组为(15. 1±2. 6)个,P=0. 003 7;淋巴结转移病例中,注墨组平均每例清除转移淋巴结(7 .8±1 .7)个,对照组(4. 2±2. 0)个,P=0. 004 5;注墨组总的淋巴结黑染率62 .0%, 转移淋巴结黑染率66. 4%。结论:局部应用微粒子炭对指导直肠癌手术中的淋巴结清除具有统计学意义。
Objective: To investigate the clinical significance of microparticle charcoal in removing lymph nodes during the operation of rectal cancer. Methods: A prospective case-control study was conducted. The patients were randomly divided into four groups. Forty patients with rectal cancer underwent preoperative colonoscopy with local injection of charcoal charcoal followed by radical resection of rectal cancer, and 40 patients undergoing conventional radical resection of rectal cancer as the control group. All cases recorded the number of lymph nodes removed and pathological examination. Results: The lymph nodes were clearly stained during operation. The number of clear lymph nodes in each group was (24.6 ± 4.2) cases in control group and (15.1 ± 2.6) cases in control group, P = 0. 003 7; in cases of lymph node metastasis, the number of metastatic lymph nodes (7 .8 ± 1. 7) in control group (4.2 ± 2.0) was significantly lower than that in control group (P = 0.00005) Injecting group total lymph node black dye rate of 62.0%, metastatic lymph node black dye rate of 66.4%. Conclusion: Topical application of charcoal charcoal has statistical significance in guiding lymph node dissection in rectal cancer surgery.
