Objective To summarize the experience of the diagnosis and treatment of pulmonary hamartoma.Methods Bronchoscopic enucleation of tumor was conducted in 1 case of endobrochial hamartoma, while video-assisted thoracoscopic surgery was performed in 42 cases(consisting of 40 cases of pulmonary wedge resection,1 case of lobectomy,and 1 case of bilateral lesion biopsy).Results Pathological examinations revealed hamartoma in all the 43 cases,including 1 case of multiple lesions and 1 case of hamartoma complicated with lung cancer.The diagnostic accordance rate was 11.6%(5/43).Follow-up in 37 cases for 4 months~ 11 years(mean,41.2 months) showed no recurrence or malignant change.Conclusions Pulmonary hamartoma is difficult to be confirmatively diagnosed preoperatively.Endoscopic operations can give an accurate diagnosis and a thorough removal of the lesion,with minimal invasion and rapid recovery.

Objective To evaluate the clinical effects of endobronchial ultrasound - transbronchial needle aspiration (EBUS-TBNA) in the evaluation of staging of lung cancer.Methods Between July 2008 to March 2010,the first 128 patients selected by CT or PET/CT scanning with lung cancer in whom metastatic carcinoma in the hilar and/or mediastinal lymph nodes underwent EBUS-TBNA and were clinically followed up.There were 102 males and 26 femals with the age of 37 - 85 years,average 60.1 years.Review the performance in check and the result of biopsy.Results From 128 patients of mean age 60.1 years ( range 37 - 85 ),189 lymph nodes were punctured.The mean diameter of the nodes was 12.3 mm and the range was 6-16 mm.There were no procedural complications.Accuracy,sensitivity,and specificity for EBUS-TBNA were 98.53％,98.50％,and 100％,respectively.Conclusion EBUS-TBNA allows real-time visualization of mediastinal and hilar lymph nodes,allowing sampling safely and efficiently.It has great potential for diagnosis of staging of lung cancer.

Purpose To evaluate the application value of using a-cyanoacrylate rapid medical glue in preoperative localization of ground-glass nodules under CT guidance.Materials and Methods 48 cases were retrospectively analyzed,in which the pulmonary ground-glass nodules took preoperative localization under CT guidance.The rapid medical glue was injected in pulmonary ground-glass nodules,which was used for preoperative localization.Results After preoperative localization of rapid medical glue in 48 cases,pulmonary ground-glass nodules of all patients were resected successfully by video-assisted thoracoscope surgery (VATS).The complications of pneumothorax did not occur in all cases,with little pulmonary hemorrhagein in 10 cases.Conclusion When the fast medical glue has been used in the CT-guided preoperative localization of ground-glass nodules,there are advantages of high accuracy of localization and surgery.Moreover,this method is simple,safe and effective.

Objective To study the feasibility and effect of scarless endoscopic thyroidectomy(SET) and minimally invasive video-assisted surgery of the thyroid(MIVA) endoscopic technique. Methods SET: Incisions were made on the anterior part of the breast and mareolata,blunt dissection of the subcataneous planes of the neck and chest were administered .MIVA: Incisions were made 3cm above the thymus notch and the operation was video assisted in the thyroid adenoma extripation and subtotal thyroidectomy. The thyroid nodules were extirpated or subtotal thyroidectomy was performed. Results All 10 cases of the SET and 12 cases of the MIVA were successful performed and without complications. Conclusions For thyroid surgery,SET is a good cosmetic operation,MIVA is a minimal trauma and effective operation.
