目的比较麦默通系统(MMT)与传统乳腺肿块切除术在乳腺较大良性肿块治疗中的优劣。方法 90例乳腺良性肿块(直径2~5cm)患者按手术方式分为MMT组(40例)和传统乳腺肿块切除术组(对照组,50例),比较两组各项手术相关指标。结果与对照组相比,MMT组术后乳腺形态改变少(2.5%vs.18.0%),切口感染率低(2.5%vs.20.0%),患者满意率高(97.5%vs.80.0%),但术中出血多[(19.13±6.29)ml vs.(11.04±8.58)ml],术后3d皮下瘀斑或血肿发生率高(20.0%vs.4.0%),术后3个月肿块残留率高(20.0%vs.4.0%),住院总费用高[(10362.30±2625.79)元vs.(6950.30±1747.24)元](P均<0.05)。结论与传统手术相比,MMT治疗乳腺较大良性肿块具有美观、切口感染率低的优点,但术中出血多,易形成乳腺内血肿和肿块残留,总费用高。
Objective To compare the advantages and disadvantages of using Mammotome system (MMT) and traditional breast tumor excision in the treatment of larger benign breast masses. Methods Totally 90 patients with benign breast mass (diameter 2 ~ 5cm) were divided into MMT group (40 cases) and conventional mammary tumor resection group (50 cases) by surgery. The operative indexes of the two groups were compared. Results Compared with the control group, the postoperative changes of breast morphology in MMT group were less (2.5% vs. 18.0%), the incision infection rate was lower (2.5% vs. 20.0%), the satisfaction rate was higher in patients with MMT (97.5% vs. 80.0% (19.13 ± 6.29) ml vs. (11.04 ± 8.58) ml], the incidence of subcutaneous ecchymosis or hematoma was high (20.0% vs.4.0%) after operation, and the residual rate at 3 months High (20.0% vs.4.0%), high total cost of hospitalization [(10362.30 ± 2625.79) yuan vs. (6950.30 ± 1747.24) yuan] (all P <0.05). Conclusion Compared with traditional surgery, MMT has the advantages of good appearance and low incision infection rate in the treatment of large breast benign masses. However, intrahepatic hematoma and mass remnants are easily formed in the operation, and the total cost is high.
