RESULTS: Operative time for VATS resection with VM (group 1) and VATS pulmonary resection alone (group 2) was 198±64 vs. 167±43 min (P=0.003). Mean/median numbers of dissected nodal stations were 4.93±1.1/5 (range, 4-8) in group 1 and 3.25±0.5/5 (range, 3-8) in group 2 (P<0.001).

On the left side (n=60) group 1 vs. group 2 lymphadenectomy resulted at station 4 in 6 (85.7%) and 38 (71.7%); at station 5/6 in 6 (85.7%) and 26 (49%); at station 7 in 6 (85.7%) and 33 (62.3%), and at station 8/9 in 1 (14.3%) and 18 (34%).

Abstract

To assess if video-mediastinoscopy (VM) with frozen sections (FS) combined with a video-assisted thoracic surgery major pulmonary resection (VMPRS) is able to improve VATS mediastinal intraoperative staging. METHODS: From June 2012 to March 2015 a total of 146 patients underwent VMPRS lymphadenectomy. NCCN guidelines were followed for pre-operative staging, including VM with FS in 27 patients (19%). Procedural time, dissected nodal stations, complications related to VM and VATS lymphadenectomy and definitive histology, were evaluated. RESULTS: Operative time for VATS resection with VM (group 1) and VATS pulmonary resection alone (group 2) was 198±64 vs. 167±43 min (P=0.003). Mean/median numbers of dissected nodal stations were 4.93±1.1/5 (range, 4-8) in group 1 and 3.25±0.5/5 (range, 3-8) in group 2 (P<0.001). Group 1 vs. group 2 right-sided lymphadenectomy (n=86) was performed at station 2R/4R in 18 (90%) and 46 (69.7%); at station 3a/3p in 14 (51.8%) and 22 (31%); at station 7 in 18 (90%) and 44 (66.7%); at station 8/9 in 11 (55%) and 24 (36.4%) respectively. On the left side (n=60) group 1 vs. group 2 lymphadenectomy resulted at station 4 in 6 (85.7%) and 38 (71.7%); at station 5/6 in 6 (85.7%) and 26 (49%); at station 7 in 6 (85.7%) and 33 (62.3%), and at station 8/9 in 1 (14.3%) and 18 (34%). There were no early deaths and recurrent laryngeal nerve palsy occurred in 1 (0.8%) in group 2. Pathological upstaging (pN1; pN2) was found in 5 patients (17%) in group 1, and 13 (11%) in group 2 (P=0.23). About FS (n=29), formal paraffin histology resulted in 0% of both, false negative and false positive results. CONCLUSIONS: Based on our experience, the combination "VM with FS followed by VMPRS in sequence", seems to be effective and offers an alternative approach to improve intraoperative mediastinal staging.
