In elderly patients, malnutrition was a significant additional risk factor for early death. Nutritional assessment should be included in the routine preoperative selection. In malnourished patients, nutritional support before and after operation and a careful postdischarge care might be beneficial, but it should be corroborated by further prospective studies.

Our preliminary results showed that the LigaSure is an efficient tool for closing the intestines when sero-serosa stumps are created. The second step of our work will be to evaluate the feasibility of this tool in creating intestinal anastomoses.

The learning curve was bimodal. After the initial 30 lobectomies, oncologic quality of the procedure improved and stabilized. The surgeon became less selective and accepted to proceed with more complex cases (incomplete fissures, pleural adhesions). Efficiency was obtained after 90 lobectomies (shorter operative time and lower conversion rate).

AbstractDescending Necrotizing Mediastinitis (DNM) is a polymicrobic, dangerous and often fatal process, arising from head or neck infections and spreading along the deep fascial cervical planes, descending into the mediastinum. It can rapidly progress to sepsis and can frequently lead to death. It has a high mortality rate, up to 40% in the different series, as described in the literature. Surgical and therapeutic management has been discussed for long time especially in an elderly patient population. The literature has been reviewed in order to evaluate different pathogenesis and evolution and to recognise a correct therapeutic management.

Our study seems to confirm the feasibility of creating intestinal anastomosis using LigaSure. However, further researches in in vivo models are mandatory before recommending its clinical usage in such settings.

Our results showed that metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 might be valuable markers in differentiating benign from malignant pleural effusions. Their levels are neither influenced by the histology and tumour origin nor by the presence of tumour cells in pleural effusions. Thus, their use in clinical practice could help in the selection of patients needing more invasive procedures, such as thoracoscopic biopsy.

Our results seem to confirm that in selected cases, video-assisted thoracoscopic thymectomy allows complete resection of thymus and perithymic tissue, similar to sternotomy but with the known advantages of minimally invasive surgery including less pain and a good cosmetic result.
