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

introductionProtracted dysphagia and bloating are potential troublesome side effects following Nissen fundoplication. The aim of this study was to evaluate the effects of conversion from Nissen to Toupet on dysphagia and bloating.

methodsThe study used a retrospective chart review of all patients who had undergone conversion from Nissen to Toupet between 2001 and 2014. Endpoints were to determine the effect of conversion on dysphagia, bloating, and reflux control.

resultsTwenty-five patients underwent conversion at a median of 3.7 years (1.4-10.5) after initial fundoplication. Indications were dysphagia in 19 (76%) and bloating syndrome in 6 (24%) patients. The median operative time was 104 min (86-146). There were no serious complications or mortality. Median follow-up was 27 months (0.8-130). Dysphagia was relieved in 16 (84%) and bloating in all 6 patients. Two patients developed reflux requiring a redo-Nissen. Two patients had persistent dysphagia and required endoscopic dilation. The GERD-HRQL post-conversion showed a median score of 5 (3-13).

conclusionsConversion relieved dysphagia in 84% and bloating in 100%. Significant recurrence of GERD was rare. Given the absence of serious complications, conversion should be considered in patients with severe bloating or dysphagia.
