OBJECTIVES Only few studies compared the surgical morbidity and mortality of thoracoscopic segmentectomy versus lobectomy for non-small-cell lung cancer, in particular, by relating the segmental resections with the corresponding anatomical lobes. METHODS We enrolled a total of 7487 patients who underwent VATS lobectomy (7269) or segmentectomy (218) from January 2014 to July 2019. A propensity score matching approach was used to account for potential confounding factors between the 2 groups. After matching, 349 lobectomies and 208 segmentectomies were included in the analysis. We analysed the operative and postoperative outcomes of video-assisted anatomical segmentectomy compared with video-assisted lobectomy and, in details, the results of segmentectomy with its corresponding lobectomy in a large cohort of patients from the Italian VATS Group Registry. RESULTS The overall conversion rate to thoracotomy was not statistically different between the groups (27 patients 8% vs 7 patients 3%, P = 0.1). The lobectomy group had a greater number of resected lymph nodes (median 11 vs 8, P = 0.006). No significant differences were detected in 30-day mortality (1.4%, 5 patients vs 0.9%, 2 patients), overall complications (18%, 62 patients vs 14%, 29 patients) and prolonged air leakage (31 patients, 9% vs 12 patients, 6%) between lobectomy and segmentectomy, respectively. No statistical differences were found regarding the median duration of drainage (3.2 days, P = 1) and the overall median length of hospital stay (6.4 days, P = 0.1) between the 2 groups. In the context of segmentectomy versus corresponding lobectomy, the right upper lobectomy compared with right upper segmentectomy showed a higher number of resected lymph nodes (P = 0.027). No statistical differences were reported in terms of conversion rate and postoperative complication and mortality. CONCLUSIONS Segmentectomy could be considered a safe procedure without significant differences compared to thoracoscopic lobectomy in terms of postoperative morbidity and mortality.

The Mausoleum of Theodoric (520 ca.), one of Ravenna’s most globally renouned monuments and UNESCO heritage site, has been object of archeoastronomical research in the past years. This paper examines the orientation of the building as well as other elements of the architecture, especially the small openings of the building, to investigate their possible archaeoastronomical significance. The architectural survey was carried out with a laser scanner device (Faro-Focus 3D, software Scene) while the textures were extracted using digital photomodelling software. Starting from the archaeoastronomical analysis, a 3D model was developed to check astronomical phenomena and allow the communication of scientific content through several forms of media. This second part of the contribution is part of the experiments conducted by the research group (Incerti and Iurilli 2014), (Incerti and Iurilli 2015), focusing on new means of multimedia communication, both interactive and not. The research looks at virtual models as a means of edutainment, aiming to maximise the fruition of artifacts and cultural sites.
