目的:探讨乳腺癌手术保留肋间臂神经(ICBN)的临床价值。方法:选取72例乳腺癌患者作为研究对象,分为研究组与对照组,均为36例,两组患者均行乳腺癌腋窝淋巴结切除术,研究组保留ICBN,对照组切除ICBN。结果:两组患者的手术时间、淋巴结清除数均差异不明显,无统计学意义(P>0.05);研究组的上肢感觉障碍率为11.11%,明显优于对照组的83.33%,差异明显,有统计学意义(P<0.05)。结论:在乳腺癌手术中保留ICBN,有利于降低术后患侧上肢感觉障碍的发生率,值得推广。 Objective: To investigate the clinical value of preserving intercostobrachial nerve (ICBN) in breast cancer surgery. Methods: Totally 72 breast cancer patients were selected as research group and control group, all of which were 36 cases. All patients underwent axillary lymph node dissection of breast cancer. ICBN was reserved in study group and ICBN was removed in control group. Results: There was no significant difference between the two groups in the operation time and lymph node clearance (P> 0.05). The rate of upper extremity sensation was 11.11% in the study group, which was significantly better than that in the control group (83.33%), There was statistical significance (P <0.05). CONCLUSION: Preserving ICBN during breast cancer surgery is beneficial to reduce the incidence of upper limb sensory disturbance in postoperative patients and is worth promoting.
