目的探讨染料法腋窝反向淋巴作图(ARM)在乳腺癌改良根治手术中的应用。方法采用病例对照研究方法,选取行改良根治手术+ARM成功的45例患者(观察组)与同期45例只行改良根治术患者(对照组),比较两组患者术后腋窝引流量、腋窝引流管留置天数及术后患者上肢水肿发生率。结果观察组患者与对照组比较,术后腋窝引流量明显减少(P<0.05),腋窝引流管留置时间明显缩短[(11.8±4.2)d和(8.9±2.7)d,P<0.05)],术后患者上肢水肿发生率明显减少(17.8%和33.3%)。结论 ARM技术可减少术后上肢水肿发生率。 Objective To investigate the application of dye axillary reverse lymphography (ARM) in modified radical mastectomy for breast cancer. Methods A case-control study was conducted in 45 patients (observation group) and 45 patients with modified radical mastectomy (control group) undergoing modified radical mastectomy plus ARM. The axillary drainage and axillary drainage were compared between the two groups Tube indwelling days and postoperative patients with upper extremity edema incidence. Results Compared with the control group, axillary drainage was significantly decreased in the observation group (P <0.05), and the retention time in the axillary drainage tube was significantly shorter (11.8 ± 4.2 days and 8.9 ± 2.7 days, P <0.05) Postoperative patients with upper limb edema significantly reduced the incidence (17.8% and 33.3%). Conclusion ARM can reduce the incidence of postoperative upper limb edema.
