Who Needs Endoscopic Removal of Food Residue From the Esophagus Before Peroral Endoscopic Myotomy for Esophageal Achalasia and Esophagogastric Junction Outflow Obstruction?

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
Objectives: Peroral endoscopic myotomy (POEM) is an established treatment for esophageal achalasia. Despite favorable outcomes, the risk of reflux aspiration during general anesthesia induction in POEM remains a concern. This study aimed to identify the risk factors for food residue in the esophagus before POEM and evaluate the necessity of esophagogastroduodenoscopy (EGD) and cleansing the day before POEM. Methods: A retrospective analysis of 61 patients with esophageal achalasia and esophagogastric junction outflow obstruction undergoing POEM between July 2017 and March 2024 was performed. Patients were divided into two groups based on the presence of food residue observed during preoperative EGD: residual ( Results: In univariate analysis, residual food was more common in patients aged <60 years ( Conclusions: Preoperative EGD and esophageal cleansing the day before POEM may be warranted in patients with initial EGD-detected residue, younger age, and marked dilation, to reduce reflux aspiration risk and improve procedural safety.
