Diagnostic accuracy and safety of rigid medical thoracoscopy in undiagnosed pleural effusion and ILD: Retrospective study of 100 patients

Aim of study: A retrospective study of diagnostic evaluation, safety and thoracoscopic findings in 100 cases was done at thoracoscopy unit of Chest Department Mansoura University Hospitals in the last two years. Results: We studied 100 patients in two groups, first group (G1) consisted of 85 male patients (67.1%) with undiagnosed pleural effusion and the second group (G2) consisted of 15 undiagnosed ILD female patients (60%). Final histopathologic diagnosis in the first group revealed metastatic adenocarcinoma in 35.3%, para-pneumonic 44.7%, TB 10.6%, NHL7.1% and mesothelioma 2.4%, while in the second group it was metastatic adenocarcinoma 6.7%, UIP 46.7%, NSIP 13.3%, TB 6.7%, BAC 13.3%, silicosis 6.7% and lastly LIP in 6.7%. We found that time of ICT removal was significantly lower in the first group with p value 0.001 and complication incidences were variants; fistula was significantly lower in the first group while empyema and surgical emphysema were significantly higher in the first group with p value 0.001. Conclusion: VAMT is a good tool for the diagnosis of undiagnosed pleural diseases and is promising in ILDs, safe, and inexpensive with minimally tolerable complications. (C) 2015 The Authors.
