TRANSTHORACIC NEEDLE LUNG BIOPSY / ASPIRATION (TTNBX/ASPIRATION) UNDER ULTRASOUND CHEST GUIDED

Abstract

Objective: To determine efficacy sensitivity specificity and complication of Tranthoracic needle lung biopsy / aspiration (TTNBx/aspiration) under ultrasound chest guided compared to US mata-analysis national survey.

Methods: Prospective data collection and retrospective descriptive study, collected patients from 1 January 2002 – 31December 2003 with peripheral lung nodule/mass which can approach lung mass by ultrasound chest, patient had to explained risk/benefit and complications in this procedure. Patient must have normal coagulogram, acceptable PFT, good cooperation and sign Informed consent.

Results: The sensitivity and specificity for diagnosis of primary and secondary lung cancers by transthoracic needle biopsy/aspiration was 94.3% and 96% respectively. The incidence of complication was quite low and no mortality was found.

Conclusions: Transthoracic needle biopsy/aspiration of peripheral lung lesions under ultrasound chest guided is good technique for diagnosis of pulmonary disease, which had high sensitivity and specificity, very low complication and low cost. Any physicians can feasibly be trained for good skill to do this procedure. Clinical criterias for pretest probability for malignancy included having other malignancy, cavitary tumors, tumor size more than 3 cm., significant weight loss, history of smoking and age more than 50 years old.
