Sensory Changes and Postmastectomy Pain Following Preservation of Intercostobrachial Nerve in Breast Cancer Surgery: a Prospective Randomized Study

AbstractSurgery for breast cancer leads to sensory changes and persistent pain in about 20 –60% of patients and is usually attributed to section of the intercostobrachial nerve (ICBN). However, the opinion is divided about the benefit of preservation of ICBN. Hence, this study was designed to assess the role of preservation of ICBN on sensory changes and acute and persistent pain follow ing mastectomy. The study was conducted on patients undergoing modified radical mastectomy for breast cancer. At the time of surgery, ICBN was sacrificed in group I (N = 29), and preserved in group II (N = 24). Patients underwent sensory assessment for touch and pain in predefined areas after surgery. They were also assessed for acute post-operative pain and persistent pain (PP) on day 30 and 90 by numeric pain rating scale. PP was also evaluated by douleur neuropathique 4 questionnaire for ass essment of its neuropathic character. Preservation of ICBN resulted in significantly better preserved sensation on lateral aspect of mastectomy incision, axilla, and medial aspect of the arm. Frequency and severity of acute post-operative pain were similar between the two groups. However, PP was sig nificantly reduced in ICBN preserved group. At 3 months, 31% patients in group I and 12.5% in group II had clinically significant pain (p = 0.024). DN 4 assessment showed neuropathic character of pain in 20.6% and 8.33% in group I and II respectively. In our study, preservation of ICBN resulte...
