Axillary dissection is one of the important components of modified radical mastectomy (MRM). The present study was conducted to compare surgical outcomes by using monopolar electrocautery and ultrasonic dissector for axillary dissection in MRM.
A parallel randomised controlled single blinded study was conducted with a sample size of 70 patients who were randomised into two groups. One group underwent MRM using ultrasonic dissector (Group A) and the other one using electrocautery (Group B). Intra- and post-operative outcomes were compared.
Group A had an average operating time of 30.86 min, which was statistically less than that of Group B. The mean mop count and the daily drain output in Group A were less as compared to Group B and the differences were statistically significant. Drain was removed early in Group A as compared to Group B. However, post-operative pain scores and seroma formation were not statistically significant among the two groups.
Ultrasonic dissector group had significantly lesser intra-operative bleeding, operating time and post-operative drain output when compared to electrocautery group. However, the two groups had no significant difference in post-operative pain scores and seroma formation.
腋窝淋巴结清扫是改良根治性乳房切除术（MRM）的重要组成部分之一。本研究旨在比较在MRM中使用单极电灼器和超声刀进行腋窝淋巴结清扫的手术效果。
进行了一项平行随机对照单盲研究，样本量为70例患者，随机分为两组。一组使用超声刀进行MRM（A组），另一组使用电灼器（B组）。比较术中及术后结果。
A组平均手术时间为30.86分钟，在统计学上少于B组。与B组相比，A组的平均纱布计数和每日引流量较少，差异具有统计学意义。与B组相比，A组引流管拔除较早。然而，两组术后疼痛评分和血清肿形成在统计学上无显著差异。
与电灼器组相比，超声刀组术中出血、手术时间和术后引流量明显更少。然而，两组术后疼痛评分和血清肿形成无显著差异。
