Electrocautery has been proven to be associated with prolonged serous drainage that might result in several complications in patients requiring axillary lymph node dissection for breast cancer. We proposed that the Harmonic Focus might outperform electrocautery in axillary lymph node dissection, resulting in shorter operative times and reduced postoperative complications.
One hundred twenty-eight women with confirmed T1-3 N1-2 breast cancer were randomly assigned to undergo mastectomy or breast-conserving surgery with axillary dissection by using Harmonic Focus or electrocautery. Sixty-four has surgery with Harmonic Focus (group A) and 64 with electrocautery (group B) by the same surgical team. Operative time, blood loss, total drainage volume and days, incidence of seroma, hematoma, pain score, and flap necrosis were recorded.
Using Harmonic Focus significantly diminished operative time, blood loss, total drainage volume, days of stay, and visual analogue scale as compared with traditional electrocautery. There was no statistical difference between the 2 groups regarding seroma, hematoma, and flap necrosis.
Axillary lymph node dissection using Harmonic Focus is feasible, safe, and a more comfortable design for the surgeon.
电灼已被证明与长时间的浆液性引流有关，这可能导致乳腺癌腋窝淋巴结清扫术的患者出现多种并发症。我们提出，Harmonic Focus 在腋窝淋巴结清扫术中的表现可能优于电灼，从而缩短手术时间并减少术后并发症。
128 名经证实患有 T1-3 N1-2 乳腺癌的女性患者被随机分配接受乳房切除术或保乳手术，同时进行腋窝清扫，使用 Harmonic Focus 或电灼。64 名患者采用 Harmonic Focus（A 组），64 名患者采用电灼（B 组），均由同一位外科医生完成。记录手术时间、出血量、总引流量和天数、血清肿、血肿、疼痛评分和皮瓣坏死的发生率。
与传统电灼相比，使用 Harmonic Focus 显著缩短了手术时间、出血量、总引流量、住院天数和视觉模拟评分。两组在血清肿、血肿和皮瓣坏死方面无统计学差异。
使用 Harmonic Focus 进行腋窝淋巴结清扫术是可行的、安全的，并且对外科医生来说是一种更舒适的设计。
