A critical review of published literature on mediastinal lymphadenectomy requires an understanding of the described operative technique. Sampling refers to the technique of removing easily found and obviously abnormal mediastinal lymph nodes. Systematic sampling refers to the routine biopsy of lymph nodes at levels or stations as specified by the authors. Complete mediastinal lymph node dissection refers to the routine complete removal of all mediastinal tissue as described by the authors.
