Is an intercostal chest drain necessary after video-assisted thoracoscopic (VATS) lung biopsy?
GROUND: Video-assisted thoracoscopic surgical lung biopsy is a frequently performed procedure as an integral part of the diagnostic armamentarium for parenchymal lung disease. However, there is no evidence in the literature concerning the need for an intercostal chest drain after the procedure. METHODS: A prospective randomized control trial was set up to assess the need for intercostal chest drainage after video-assisted thoracoscopic surgical lung biopsy. Patients who did not have any air leak after the procedure (lung tested while patient was still under anesthetic) was randomized to either having a chest drain or not. The study was powered at 0.9 using an alpha of 0.01. RESULTS: Thirty patients were recruited in each group. There were no significant differences between the two groups in terms of patients’ age (mean age, 59 versus 54 years), sex, history of steroid use, immediate postoperative pain scores, and wound complications. No significant pneumothoraces occurred in either gro
