目的：探讨乳晕边缘切口及压力封闭残腔技术在切除乳腺良性肿块中的临床应用价值。方法2006年1月至2012年5月该科对2264例乳腺良性肿块住院患者进行乳晕边缘切口切除肿块，对切除肿块后所留的残腔采用加压包扎封闭技术，通过随访，评价...目的：探讨乳晕边缘切口及压力封闭残腔技术在切除乳腺良性肿块中的临床应用价值。方法2006年1月至2012年5月该科对2264例乳腺良性肿块住院患者进行乳晕边缘切口切除肿块，对切除肿块后所留的残腔采用加压包扎封闭技术，通过随访，评价对乳腺良性肿块的治疗效果。结果采用乳晕边缘切口及加压包扎封闭残腔技术，所有乳腺良性肿块均成功切除及痊愈；单个病灶长径为0．5～8．0 cm ，病灶数量为1～42个；手术时间5～162 min ，平均37 min；乳房切口疤痕微细，保持乳房外形；硬块感率25．4％，硬块感时间18～40 d ，平均29 d；患者满意98．4％，无严重并发症。结论乳晕边缘切口及压力封闭残腔技术在乳腺良性肿块切除的临床应用中，操作简单、美观、安全可行。展开更多
