RESUMEN
Objective To evaluate the results of lung volume reduction surgery (LVRS) using domestic staplers and autologous tissue. Methods Thirteen male patients received LVRS from June 2000 to March 2006 in this hospital. The age range was 56~68 years (mean, 60.5 years). The patients had a history of chronic obstructive pulmonary disease (COPD) for 2~16 years (mean, 11 years). The operation was performed under general anesthesia, with single lung ventilation. A muscle sparing thoracotomy in the 5th intercostal space was conducted. The “target area” was identified by combination of observation and palpation during operation and preoperative CT scans. The cutting edge was stapled with domestic staplers buttressed with autologous tissue. Results All the procedures were successfully accomplished. Follow-up observations for 8 months ~ 5 years showed no dyspnea and improved activities. At 6 months after operation, the FEV_1 and the PaO_2 were increased by 94.4%?21.2% and 12.5%?3.1%, while the RV and TLC were decreased by 24.1%?7.8% and 20.8%?5.1%, respectively. All the abovementioned parameters were significantly changed before and after operation (P
RESUMEN
Objective To investigate the value of clinical application of interventional ultrasounography in the diagnosis and treatment of abdominal viscera cysts(AVCs). Methods (1)One hundred and three cases of AVCs were examined by percutaneous fine-needle aspiration biopsy(FNAB) guided by ultrasonnography;the cytologic results were compared with the pathological results after operation in 28 cases. (2) The AVCs were treated with injection of 99.5% ethanol after aspiration or draining with a tube gnided by ultrasounography. Results (1) The diagnosis rate in FNAB group(91.5%) was significantly higher than that in single ultrasounogrophy group(85.4%) (P
