乳腺癌改良根治术

Modified radical mastectomy

乳腺癌改良根治术:距肿瘤边缘约5 cm做梭形切口,在皮肤与浅筋膜间做皮瓣分离,上界为锁骨下缘,下界达肋弓处,内侧界近胸骨,外侧界为背阔肌前缘,将乳腺从胸大肌表面分离。打开胸锁筋膜,将胸大小肌向内上牵拉,显露腋窝。腋淋巴结整块切除后,保留胸大肌、胸小肌、胸前神经分支以及胸长和胸背神经。放置负压引流管。仔细伤口创面止血,缝合皮肤。

Afusiform incision was made with a 5cm distance from the edge of the tumor, and a skin flap from the superficial fascia was moblized （The upper boundary is separated to the inferior border of the clavicle, the lower boundary to the fib arch, the medial boundary to near the sternum, and the lateral boundary to the anterior border of latissimus dorsi）. Then the mammary gland was dissected from the surface of pectoralis major muscle. In order to expose the armpit, the clavipectoral fascia was open, pulling the pectoralis major and minor muscle towards the upper inner direction. After resecting the whole axillary lymph nodes, the peetoralis major muscle, peetoralis minor muscle, anterior pectoral nerve branch and long thoracic nerve and thoracodorsal nerve should be preserved. Finally, a negative pressure drainage tube was placed before careful hemostasis of the wound, and then the incision was sutured.
