Abstract： Objective To introduce the new procedure of endobronchial ultrasoundguided transbronchial needle aspiration (EBUSTBNA) for staging lung cancer and diagnosing thoracic diseases, in order to determine its value in the evaluation of thoracic diseases. Methods We retrospectively reviewed the data of all patients examined with EBUSTBNA our institution between September 2009 and May 2010. Among the patients, there were 75 males and 31 females with an average age of 62.3 years old. Based on their primary indication, we divided all the 106 patients into three categories. (1) There were 76 patients with known or bly suspected lung cancer. Enlarged mediastinal lymph nodes on radiographic examination of the chest (≥1.0 cm) were detected in all the patients. (2) There were 22 patients with enlarged mediastinal lymph nodes or mediastinal masses of unknown origin. (3) There were 8 patients with pulmonary mass located close to the central airways. Results (1) 76 patients underwent EBUSTBNA for known or bly suspected lung cancer. Among them, 58 patients were confirmed to have mediastinal lymph nodes metastasis on EBUSTBNA. Sixteen in the 18 patients with negative EBUSTBNA underwent thoracoscopy or thoracotomy for pulmonary resection and mediastinal lymph node dissection. Postoperative pathology confirmed that 12 patients did not have metastatic nodes, 2 patients had metastatic nodes and 2 other patients had benign lesions within the lung. The diagnostic sensitivity, specificity and accuracy of EBUSTBNA for the mediastinal staging of lung cancer were 96.66%(58/60), 100.00%(12/12) and 97.22%(70/72), respectively. (2) 22 patients underwent EBUSTBNA for the evaluation of mediastinal adenopathy or mass in the absence of any identifiable pulmonary lesion. Among them, 7 had malignancy, 13 had benign diseases on EBUSTBNA and the sensitivity of EBUSTBNA in distinguishing malignant mediastinal diseases was 87.50% (7/8). (3) 8 patients with pulmonary mass located close to the central airways were accessed by EBUSTBNA. Definite diagnosis was achieved in 7 patients, and lung cancer was detected in 6 patients. The sensitivity and the diagnostic accuracy of EBUSTBNA for the diagnosis of unknown pulmonary mass was 85.71%(6/7) and 87.50%(7/8), respectively. All the procedures were uneventful, and there were no complications. Conclusion EBUSTBNA is a highly effective and safe procedure. We believe that EBUSTBNA should be used routinely in the diagnosis and staging of thoracic diseases.
Objective To explore the value of the application of latissimus dorsi myocutaneous flap in the breast reconstruction. Methods The clinical data of the 36 patients with breast tumor who had undergone breast reconstruction with latissimus dorsi myocutaneous flap from January 2012 to December 2016 were collected retrospectively. The postoperative complications and cosmetic results were analyzed. Results Thirty-six patients with breast tumor who underwent breast reconstruction with latissmus dorsi myocutaneous flap, including 32 patients with immediate breast reconstruction and 4 patients with delayed breast reconstruction respectively. The operative time of the patients who undertwent immediate breast reconstruction was 235–490 min (mean of 325 min), the intraoperative blood loss was 200–260 mL (mean of 220 mL), and the hospitalization time was 18–33 d (mean of 23.6 d). The total operative time of patients who underwent delayed breast reconstruction was 325–550 min (mean of 355 min), the total intraoperative blood loss was 200–250 mL (mean of 220 mL), and the total hospitalization time was 27–45 d (mean of 32.5 d). The cosmetic results was excellent in 22 patients, good in 8 patients, fair in 6 patients, respectively, and fine rate was 83.3% (30/36). There was no flap loss, but donor site seroma occurred in 21 patients, partial necrosis of the surgical margin of back skin occurred in 1 patient, partial necrosis of the nipple and areola skin occurred in 2 patients. All the patients were followed-up for 3–60 months, and the mean follow-up time was 37 months. During the follow-up period, no patient occurred metastasis or recurrence. After undergoing radiotherapy, reconstructive breast volume of 2 patients significantly contracted. None of the patients had significant limb function. Conclusion The breast reconstruction with the latissimus dorsi myocutaneous flap is a simple, easy, and effective surgical procedure.
Objective To explore the clinical application of tissue flap in repairing the residual cavity formed by breast conserving surgery. Methods Retrospective analysis for clinical data of 120 early breast cancer patients who received breast conserving surgery in our hospital from January 2013 to December 2016 was performed. Among them, 60 cases (observation group) were implemented tissue flap repairing operation while the other 60 cases (control group) were operated by using the traditional surgery method. The clinical data of the two groups were compared analytically in four aspects: postoperative complications, postoperative breast beauty, subjective satisfaction of patients, and postoperative recurrence and metastasis. Results ① Postoperative complications: 3 cases of complications occurred in the control groupand 2 cases in the observation group, and there was no significant difference in the incidence of complications between the 2 groups (χ2=0.209, P=0.648). ② Postoperative breast beauty: in the control group, there were 23 excellent cases, 16 good cases, 12 common cases, and 9 poor cases; in the observation group, there were 51 excellent cases, 5 good cases, 3 common cases, and 1 poor cases. The difference of postoperative breast beauty between the 2 groups was statistically significant (Z=–5.234, P<0.001). ③ Subjective satisfaction of patients: in the control group, 28 cases very satisfied, 18 cases satisfied, 12 cases generally satisfied, and 2 cases dissatisfied; in the observation group, 40 cases satisfied, 18 cases very satisfied, and 2 cases generally satisfied. The subjective satisfaction of the patients in the observation group was better than that of the control group (Z=–4.381, P<0.001). ④ Postoperative follow-up: no recurrence and death occurred in both of 2 groups, but 2 cases occurred metastasis in the control group and 1 case in the observation group. The contrast difference in the incidence of metastasis was not statistically significant (χ2=0.342, P=0.559). Conclusion During breast conserving surgery, the use of surrounding tissue flap to repair residual cavity, compared with traditional breast conserving surgery without tissue flap repairment, does not increase postoperative complications, recurrence, and metastasis, and it has good cosmetic effect after breast surgery, as well as the patients’ subjective satisfaction is good.
ObjectiveTo investigate the anatomical characteristics of breast lymphatic drainage in patients with breast cancer after injecting methylene blue and indocyanine green (ICG) into the intradermis of the areola.MethodsOne hundred and eighty-six patients with stage 0–Ⅱ breast cancer were collected. The sentinel lymph node (SLN) biopsy was performed by injecting methylene blue and ICG. At the same time, the number of sentinel lymphatic channel (SLC), origin angle, direction, and consistency were also studied.ResultsA total of 308 SLCs were successfully showed in the 186 patients and 679 SLNs were detected. The 95.8% (295/308) of SLCs and 93.1% (632/679) of SLNs were showed by combination in the methylene blue and ICG. The 46.8% (87/186) of patients had 1 SLC, the 40.9% (76/186) of patients had 2 SLCs, the 12.4% (23/186) of patients had 3 SLCs. The 82.8% (255/308) of SLCs flowed from the outer upper edge of the areola, the 3.2% (10/308) of SLCs flowed from the outer lower edge of the areola, the 14.0% (43/308) of SLCs flowed from the inner upper edge of the areola. The 89.9% (277/308) of the SLCs flowed mainly through the 0°—60° interval in the outer upper quadrant, 10.1% (31/308) of the SLCs flowed through the 61°—90° interval in the outer upper quadrant.ConclusionsThe consistency of SLC and SLN stained by the two tracers is good. The number of SLC is 1–3. The SLCs flow mainly through the 0°—60° interval in the outer upper quadrant of the breast, then flow into in the axilla and don’t flow into the internal mammary lymph nodes. The deep superficial lymphatic channels under the skin and the penetrating lymphatic channels can not be showed by ICG, but the SLN can be showed by it.
