Development of pseudoachalasia following magnetic sphincter augmentation (MSA) with restoration of peristalsis after endoscopic dilation.
Article in Clinical journal of gastroenterology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Pseudoachalasia is mimicking clinical and physiologic manifestations of idiopathic achalasia but results from alternative etiologies that infiltrate or obstruct the esophagogastric junction (EGJ). Anti-reflux surgery is one of the potential etiologies of pseudoachalasia. The majority of cases with persistent dysphagia after a tightly constructed Nissen fundoplication results from EGJ outlet obstruction (EGJOO) and in rare cases progresses to pseudoachalasia. In these extreme cases, endoscopic dilation is not a sufficient treatment and take down of fundoplication would be necessary. In this case report, we present a patient with long-standing GERD symptoms that underwent magnetic sphincter augmentation (MSA) with complete resolution of his reflux symptoms. He did not have dysphagia prior to surgery and his preoperative manometry showed normal peristaltic progression of esophageal contractions. He developed pseudoachalasia 14 months after surgery. Repeated endoscopic dilation in this case resulted in resolution of dysphagia and complete restoration of peristaltic contractions.
