Transoral endoscopic mediastinal surgery (TOEMS)-results of a first clinical study for scarless mediastinal lymph node biopsies.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundVideo-assisted mediastinoscopy (VAM) represents the standard procedure for mediastinal lymph node biopsies. This operation results in a scar at prominent position at the anterior neck. Since there is a trend to less invasive procedures, natural orifice transluminal endoscopic surgery (NOTES) was introduced to different fields of surgery. Based on NOTES we developed a new approach for mediastinoscopy: transoral endoscopic mediastinal surgery (TOEMS). In previous studies using human cadavers and living pigs the feasibility of TOEMS was shown. It was unclear whether TOEMS could be safely applied in patients requiring mediastinal lymph node biopsies.
methodsWe conducted a clinical phase I study recruiting ten patients with unclear mediastinal lymphadenopathy not resolved by prior bronchoscopy. All patients underwent TOEMS for mediastinal lymph node biopsy. The duration of the procedure and complications were monitored. In addition, all patients were examined for pain, swallowing dysfunction and sensation disturbance.
resultsTOEMS was accomplished in eight patients. In two patients operation was converted to VAM due to technical problems. Mediastinal lymph nodes were dissected in all patients who finished with TOEMS. On average, two separate lymph stations were reached by TOEMS. Duration of the procedure was 159±22 min. Permanent palsy of the right recurrent laryngeal nerve was noticed in one patient postoperatively.
conclusionsThis is the first report for a human application of NOTES in thoracic surgery. In fact, transoral endoscopic surgery seems to be a feasible approach for mediastinal lymph node biopsies. Further studies are needed to show whether this procedure has an advantage over VAM in terms of pain, complications and accessibility of mediastinal lymph node stations.
