Abstract

The role of video-thoracoscopy (VT) as an invasive diagnostic procedure for mediastinal lesions not reachable by cervical mediastinoscopy (CM) has still to be defined, particularly with regard to parasternal mediastinotomy (PMT). Diagnostic efficiency and morbidity of the three methods were assessed and compared in a consecutive series over a 18 months-period after determination of a new diagnostic strategy. Among 77 interventions in 73 patients the following distribution of the methods referred was achieved: 42 CM (paratracheal and anterior subcarinal biopsies), 17 PMT (biopsies of anterior mediastinal lesions) and 18 VT (3 paratracheal, 3 posterior subcarinal, 3 anterior, 5 aortico-pulmonary window, 4 posterior biopsies or resections). All procedures were performed in general anesthesia for VT the double-lumen technique was used. Drains could be removed not later than the second postoperative day. In 7/17 cases of PMT the pleural space was opened and drained. Mean operation time (incl. waiting period for intraoperative frozen section and complete resection in a few cases) was 77 (45-100) min for VT, 49 (10-180) min for PMT and 41 (20-105) min for CM. Histological diagnosis of biopsy specimens were conclusive in all VT cases, ...Continue Reading
