目的　通过改进乳癌手术操作及引流方法 ,减少术后并发症。方法　对 12 1例乳癌根治术采用小切口、大刀削切游离皮瓣、双管负压引流、并与传统手术方法相比较。结果　采用改进措施后 12 1例中仅 5例出现皮下积液 ,3例出现皮瓣坏死 ,明显少于传统手术。结论　乳癌根治术应用小切口、大刀削切游离皮瓣 ,双管负压引流能明显减少术后近期并发症 Objective To reduce postoperative complications by improving breast cancer surgery and drainage methods. Methods A total of 121 cases of radical mastectomy were performed with a small incision, a large knife to cut free flaps, and dual-barrel negative pressure drainage, compared with traditional surgical methods. Results After the improvement measures, only 5 cases of 12 cases had subcutaneous effusion and 3 cases had flap necrosis, which was significantly less than traditional surgery. Conclusion The use of small incision, large knife cutting of free flap for radical mastectomy, and double-barrel negative pressure drainage can significantly reduce the postoperative short-term complications.
