Background: The reported diagnostic yield from bronchoscopies in patients with lung cancer varies greatly. The optimal combination of sampling techniques has not been finally established.
Background: There have been few reports regarding long time survival after lung cancer surgery. The influence of age and pulmonary function on long time survival is still not fully discovered. Some reports suggest that hospitals with a high surgical volume have better results. The aim of this study was to evaluate lung cancer surgery performed in a county hospital in terms of 30 days mortality, complications and predictors of long time survival.
BackgroundThe knowledge of the mediastinal lymph node positions from an intrabronchial view was important for conventional transbronchial needle aspiration (TBNA). The introduction of endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) changed the focus from the intrabronchial landmarks to the real life ultrasound images. However when all EBUS reachable lymph nodes are evaluated (mapping), the knowledge of the intrabronchial positions is crucial. The objective of this study was to present a new expert opinion map from an intrabronchial perspective validated by an interobserver variation analysis.MethodsPhysicians who had performed more than 30 EBUS-TBNA were included. They marked areas for optimal TBNA sampling on standardized pictures from an intrabronchial perspective. Areas marked by more than 3 of the 14 experts who had performed more than 1000 EBUS provided the data for the map. The map was validated among the experts and the agreement was compared to the agreement among less experienced physicians.ResultsThere was high agreement (>80 %) among the experts in lymph node positions 4 L, 7, 10 L, 11R and 11 L. The agreement for 4R and 10R was low (<70 %). The agreement among the most experienced physicians was significantly higher than the less experienced physicians in station 10 L (92 % vs. 50 %, p:0.01).ConclusionsIt was possible to present a new map of expert opinion for optimal sampling positions in lymph node stations 4 L, 4R, 7, 10 L, 11R and 11 L. All positions except 4R had high agreement. No area was covered by more than 3 of the 14 experts in station 10R.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
