Therefore, it is necessary to explore ... We retrospectively analyzed the short-term outcomes regarding intraoperative unplanned events, postoperative complications, and lymphadenectomy in 61 patients who underwent prone position thoracoscopi... Of these sixty-one patients, there were 10, 24 and 27 cases of tumor in the upper, middle, and lower thoracic, respectively. Although there were five cases of unplanned events during surgery, no conve... The prone position thoracoscopic-assisted TME is a safe procedure that is more conducive to thoracic lymph node dissection, especially for middle and lower mediastinum....
