To determine the value of transbronchial needle aspiration biopsy in the diagnosis of sarcoidosis, we reviewed a one-year experience of consecutive patients with sarcoidosis presenting with hilar and/or paratracheal adenopathy. The sensitivity of transbronchial needle aspiration biopsy in obtaining noncaseating granulomas was 90%. This yield exceeds that of most published reports of transbronchial lung biopsy and bronchial mucosal biopsy and suggests that transbronchial needle aspiration biopsy may be a valuable diagnostic tool in the evaluation of these forms of sarcoidosis. 相似文献

Background
Conventional transbronchial needle aspiration (cTBNA) is a safe and minimally invasive procedure with a high yield for the diagnosis of large lymph nodes (LNs) in favourable locations (LNs >1.5 cm in stations #4R and/or #7). However, it is usually underutilized by pulmonologist. One of the main reasons given for not performing cTBNA is the risk of puncturing vascular structures of the mediastinum. Recently, with the twofold objective of minimize the risk of bleeding and reduce the cTBNA cost, a thinner and less expensive needle has been commercialized. It is a 23 gauge (G) needle that costs 34, 37 €. The aim of our study was to analyze the sample adequacy, diagnostic accuracy and safety of this needle in comparison with 21 and 22 G needles (average cost: 6,400 €).Methods
We retrospectively analysed medical records from patients who underwent bronchoscopy with cTBNA for the diagnosis of LNs >1.5 cm in stations #4R and/or #7 at the Thoracic Endoscopy Unit of the University Hospital of Parma from January 1st, 2007 to October 31st, 2011. Five hundred patients underwent cTBNA from January 1st, 2007 to October 31st, 2011. In order to reduce the technical and personal bias for sampling procedure we analyzed only cases sampled by a single well-trained bronchoscopist, particularly skilful at cTBNA.Results
A total of 222 patients (186 men; mean age 63 years±12, range 6-89) with LNs >1.5 cm in stations #4R and/or #7 were identified. A 23 G needle was used in 84 patients (38%), a 21 G needle in 88 patients (40%) and a 22 G needle in 50 patients (22%). No statistically significant differences between the 23 G group and the 21 or 22 G group in sample adequacy (P=0.78 and P=0.12, respectively) and diagnostic accuracy (P=0.9 and P=0.4, respectively) were found. There were no intraprocedural or postprocedural complications irrespective of the size of needle used.Conclusions
Transbronchial 23 G needle is as safe and effective as the 21 and 22 G needle for the sampling of LNs >1.5 cm in stations #4R and/or #7. For this reason, to obtain cytology specimens from large LNs in favourable locations, the 23 G needle may represent an alternative and less expensive choice compared to 21 and 22 G needles, even if our observation needs to be confirmed in a larger prospective study. 相似文献11.

Background/Purpose
For laparoscopic surgery, the creation of pneumoperitoneum still remains a must. The insertion of a Veress needle or a trocar is never perfectly safe, and almost every kind of intraabdominal organ injury due to these insertions has been reported worldwide. Here, we describe a safe technique for creating pneumoperitoneum.Methods
For the creation of pneumoperitoneum, under direct vision, the linea alba was elevated with two towel clips and then the Veress needle was inserted. We reviewed 368 patients operated on with this technique for complication rates. Ultrasound images were obtained before and during abdominal-wall lifting in 10 patients.Results
There were no injuries due to the insertion of the Veress needle or trocars. In 90% of the patients, pneumoperitoneum was created successfully on the first attempt. Ultrasound examination demonstrated a mean extra safe area of 11.8?mm during abdominal-wall lifting with this technique.Conclusions
Elevating the linea alba during Veress-needle insertion is safe. 相似文献18.

Transthoracic needle aspiration is a safe and highly accurate method in the diagnosis of intrathoracic malignancy and should be considered as the procedure of choice in metastatic disease, mediastinal masses, small peripheral nodules, and chest wall involvement. The ability of the radiologist to treat complications and to perform biopsies on an outpatient basis has led to increased acceptance and use of this procedure. 相似文献
