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

backgroundThe tubeless technique, defined as non-intubated general anesthesia with omission of chest drainage after video-assisted thoracoscopic surgery (VATS), is a new concept to further minimize surgical trauma. However, there has been little investigation into the associated feasibility and safety. Minimization of postoperative pneumothorax is challenging. We set up a "tubeless protocol" to select patients for tubeless single-port VATS with monitoring of a digital drainage system (DDS).

methodsFrom November 2016 to September 2017, 50 consecutive non-intubated single-port VATS for pulmonary resection were performed. In our study, patients with small and peripheral pulmonary lesions indicated for sublobar resections, as diagnostic or curative intent, were included. After excluding patients having tumors >2 cm, or intrapleural adhesions noted during operation, or forced expiratory volume in the 1 second <1.5 L, 36 patients were selected for tubeless protocol. The clinical characteristics and perioperative outcomes of these patients are presented.

resultsAmong 36 cases, 5 patients had minor air leaks detected using the DDS and required intercostal drainage after wound closure. Among the remaining 31 patients in whom the DDS showed no air leak, the chest drainage was removed immediately after wound closure. A postoperative chest roentgenogram on the surgery day showed full expansion in all patients without pneumothorax. Only 7 (19.4%) patients developed minor subclinical pneumothorax on the first postoperative day without the need for chest drainage. All patients were discharged uneventfully without the need for intervention.

conclusionsOur tubeless protocol utilizes DDS to select patients who can have intercostal drainage omitted after non-intubated single-port VATS for pulmonary resection. Using objective DDS parameters, we believe that this is an effective way to reduce the rate of pneumothorax after tubeless single-port VATS in selected patients.
