超声术前评估及精准定位在真空辅助微创旋切系统治疗乳腺多发良性包块中的应用

Application of preoperative ultrasound evaluation and precise positioning in treatment of breast multiple benign masses by vacuum assisted minimally invasive biopsy system

目的探讨超声术前评估及精准定位在真空辅助微创旋切系统治疗乳腺多发良性包块中的价值。方法选取我院经病理确诊的52例乳腺多发良性包块患者(共156个病灶),其中经超声术前评估及精准定位后行超声引导下乳腺包块旋切手术的患者26例(78个病灶,研究组),仅经常规超声检查后行超声引导下乳腺包块旋切手术的患者26例(78个病灶,对照组);比较两组患者的手术旋切时间、旋切刀数及术中出血率。结果两组患者所有包块均被完整切除。研究组手术时间显著短于对照组[(19.88±5.73)min vs.(30.38±9.27)min],旋切刀数显著少于对照组(14.54±6.35 vs. 21.81±9.46),差异均有统计学意义(t=-4.915、-3.254,均P<0.05)。研究组术中出血率[7.7%(2/26)]明显低于对照组[38.5%(10/26)],差异有统计学意义(χ2=6.933,P<0.05)。结论超声术前评估及乳腺包块精准定位联合术中超声引导下真空辅助微创旋切系统治疗乳腺多发包块,可缩短手术时间,减少手术刀数,降低术中出血率,可作为乳腺良性多发包块快速、微创治疗的重要手段。

Objective To investigate the value of ultrasound preoperative and precise location in vacuum assisted minimally invasive rotary cutting system in the treatment of breast multiple benign masses. Methods Fifty-two patients admitted to our hospital with breast multiple benign masses(156 lesions)diagnosed by pathology were retrospectively analyzed.Among them,26 cases(78 lesions)were performed by breast tumor rotation operation under ultrasound guidance after preoperative ultrasound evaluation and accurate location(study group),26 cases(78 lesions)were performed by breast tumor rotation operation under ultrasound guidance after conventional ultrasound examination(control group).The operation time,the number of rotary cuts and the incidence of intraoperative hemorrhage were compared between the two groups. Results All masses were completely removed in two group. The operation time in the study group[(19.88±5.73)min]was significantly shorter than that in the control group[(30.38±9.27)min],and the number of rotary cuts in the study group(14.54±6.35)was significantly less than that in the control group(21.81±9.46),there were statistically significant differences(t=-4.915,-3.254,both P<0.05). Intraoperative bleeding rate of the study group[7.7%(2/26)]was significantly lower than that of the control group[38.5%(10/26)],and the difference was statistically significant(χ2=6.933,P<0.05).Conclusion Preoperative ultrasound evaluation and precise positioning of breast masses,combined with the vacuum assisted minimally invasive rotation system via ultrasound could shorten the operation time,reduce the number of rotary cuts and intraoperative bleeding rate,which could be an alternative microinvasive method for treating breast multiple benign masses.
