Objective To discuss the surgical indication of mammotome （MMT） operation and its auxiliary diagnosis value on breast cysts. Methods Seventy-eight patients with breast cysts from May 2010 to November 2011 in this hospital were enrolled. Excision and biopsy were performed according to the following guidelines：Single cyst with inhomogeneous interna echoes and diameter at least 1 cm；Multiple cysts associated with irregular megalgia， localized thickening of breast or ineffective drug treatment after three months；High risk of breast cancer；Hypoechoic nodules and laticifers exaggerated cysts；Ultrasonography showed disorderly echo and abundant blood supply in glandular tissues around the lesions. The result of preoperative ultrasound was compared with that of postoperative pathology diagnosis. Results In these 78 breast cysts patients with preoperative ultrasound diagnosis， 40 cases were breast multiple cysts， 38 cases were multiple cysts plus untouchable hypoecho nodules；42 cases were high risk lesions， and the other 36 cases were low risk lesions. Postoperative pathology diagnosis revealed 27 cases of cystic hyperplasia， 2 cases of atypical hyperplasia， and 1 case of breast cancer in the ultrasonic high risk lesions， and 19 cases of cystic hyperplasia in the ultrasonic low risk lesions. Ultrasound diagnostic accuracy rate was 60.26%（47/78）， sensitivity was 61.22%（30/49）， and specificity was 58.62%（17/29）. The number of resection lesions was 13.00±8.16， the time of operation was （74.25±22.68） min. The average hospital stay was 1 d after surgery. The local hematoma occurred in 2 cases and no other complications occurred during one month of follow-up. Conclusions The guidelines of MMT protocoled according to clinical manifestation of breast cyst patients and imaging of high-frequency ultrasound in author’s department are simple and utility. Minimal excision and biopsy via MMT can confirm the histological type and help for early diagnosis of breast cancer and precancerous lesion. It is important and necessary to standardize the surgical indications of MMT in the clinical work.
目的 探讨超声引导麦默通（Mammotome）微创旋切系统对乳腺多发肿块进行微创切除的应用价值。方法 对56例乳腺多发肿块患者在超声引导下行麦默通微创旋切术的临床资料进行回顾性分析，评价麦默通微创旋切术在乳腺多发肿块切除中的应用价值。结果 256个乳腺肿块经术后病理学诊断均为良性，其中纤维腺瘤或乳腺腺病伴腺瘤形成224个，乳腺腺病16个，乳腺囊肿13个，导管内乳头状瘤3个。本组并发症主要为术中出血2例及术后血肿3例，发生率为8.9% （5/56）。56例患者均获临床和超声随访3～32个月，平均11个月，所有患者均无异常，乳房外观美容效果满意，未见复发及恶性病变发生。结论 麦默通微创旋切术切除乳腺多发病灶效果好，微创优势明显，操作简单、安全，值得推广。
ObjectiveTo explore the therapeutic value of ultrasound-guided minimally invasive Mammotome system for mammary glands nodules without type-B ultrasound echo. MethodsBetween May 2009 and April 2014, 95 patients with mammary glands nodules without type-B ultrasound echo accepted B-ultrasound guided mammotome rotary cutter excision. ResultsPreoperative B ultrasound showed single shot without echo in 30 cases and multiple shot without echo in 65 cases. Among the 95 cases without echo, there were 23 cases of mixed echo nodules, and 25 cases of clustered echo-free nodules. The postoperative pathological diagnosis showed non-proliferative fibrocystic changes in 78 cases, proliferative fibrocystic changes in 17 cases (including 1 case of carcinoma in situ), and 3 cases of intraductal papilloma. ConclusionUltrasound-guided minimally invasive Mammotome system is a choice for treating mammary glands nodules without type-B ultrasound echo.
Objective To explore the risk factors of perioperative insomnia in young patients with breast masses undergoing ambulatory Mammotome (MMT) minimally invasive surgery. Methods A total of 166 young female patients who were ≤40 years old, diagnosed with breast masses, undergoing ambulatory MMT between June and December 2016 in West China Hospital of Sichuan University were included in this study. Questionnaire survey and data about general condition, preoperative and postoperative Insomnia Severity Index (ISI), Hospital Anxiety and Depression Scale, and postoperative pain Visual Analogue Scale were collected in the enrolled population. Univariate analysis was used to screen the factors that might cause insomnia, and then multiple logistic regression analysis was performed to identify possible risk factors of insomnia. Results In the 166 young female patients, the mean age was (30.90±5.96) years, and the mean perioperative ISI score was 8.83±4.97. Slight insomnia was found in 39.7% (66/166) of the patients, moderate insomnia was found in 12.7% (21/166), and severe insomnia was found in 2.4% (4/166). The results of multiple logistic regression suggested that the number of breast masses [taking the number=1 as the reference, when the number=4, odds ratio (OR)=2.269, 95% confidence interval (CI) (1.917, 13.818), P=0.001; when the number>4,OR=9.359, 95%CI (4.507, 19.433), P<0.001] and the maximum diameter of breast masses [taking 1–10 mm as the reference, when the maximum diameter was 26–30 mm,OR=6.989, 95%CI (1.488, 32.785), P=0.014; when the maximum diameter >30 mm, OR=17.290, 95%CI (4.664, 64.071), P<0.001] were independent risk factors of the severity of perioperative insomnia in these young women. Conclusion It is recommended that psychological nursing and comprehensive admission education should be enhanced for young patients who have >3 breast masses or the diameter of the mass is >25 mm, aiming to improve the postoperative recovery of patients with high risk of insomnia.
