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

backgroundOur objective in this paper is to introduce a new method for handling calcified hilar lymph nodes during lobectomies by video-assisted thoracoscopy that effectively avoids arterial injury and possible conversions.

methodsThe 12 cases in this study were initially evaluated as eligible and were subsequently scheduled for thoracoscopic lobectomies. However, calcification of the hilar lymph nodes was discovered during the operations, and its presence hampered the conventional process of pulmonary artery dissection. To avoid vessel injuries and subsequent massive bleeding, we developed two techniques specific to the position and exposure of the target vessels and nodes. The space between the bronchus and lymph nodes is exposed by sharp dissection ("scissor first") either before or after suturing the artery. These techniques are illustrated in detail.

resultsSeven male and five female patients participated in this study, with an average age of 72.5 years. We performed five right-upper lobectomies, three right-middle lobectomies, three right-lower lobectomies, and a left-lower lobectomy. Using this new technique, no conversions to thoracotomy occurred. The average operation time was 125 minutes, the mean blood loss was 275 mL, and no intra-operative massive bleeding occurred. Two patients experienced minor complications, one pulmonary infection and another postoperative subcutaneous emphysema.

conclusionsThe proposed "scissor first" technique provides an effective solution for the thoracoscopic management of calcified hilar lymph nodes, and is a safe and effective method for avoiding arterial injury and conversion.
