1 · What the graph read from it

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.

2 · The registry

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

objectiveWe investigated the merits and demerits of right cervical open surgery with right trans-cervical pneumomediastinal approach in mediastinoscopic esophagectomy.

methodsTen thoracic esophageal cancer patients were treated using this approach. Under pneumomediastinum via a right neck incision, the right cervical and upper mediastinal paraesophageal lymph nodes were dissected. The left recurrent nerve lymph nodes were dissected using a left trans-cervical pneumomediastinal approach. The subaortic arch to the left tracheobronchial lymph nodes was dissected with a combined right and left trans-cervical crossover approach.

resultsThe average number of dissected lymph nodes among the right cervical and upper mediastinal paraesophageal lymph nodes identified with a right cervical open/right trans-cervical mediastinoscopic/right thoracoscopic approach was 3.2/4.0/0.6, respectively. The average number of dissected lymph nodes among the subaortic arch to the left tracheobronchial lymph nodes with a right trans-cervical mediastinoscopic/right thoracoscopic approach was 1.5/0.6, respectively. These findings indicate that, without using the right trans-cervical pneumomediastinal approach, it might be impossible to successfully remove some of the right cervical and upper mediastinal paraesophageal lymph nodes and the subaortic arch to the left tracheobronchial lymph nodes lymph nodes. Regarding surgical complications, one case of bilateral recurrent nerve palsy as well as two cases on the right and two cases on the left were noted.

conclusionsAlthough the rate of recurrent nerve palsy should still be reduced, a bilateral (especially right-sided) trans-cervical pneumomediastinal approach is an available option for achieving sufficient upper mediastinal lymph node dissection and esophagectomy.
