The Hill classification characterizes the geometry of gastroesophageal junction and Hill grades (HGs) III and IV have a high association with pathologic reflux. This study aimed to understand the use of the Hill classification and correlate the prevalence of pathologic reflux across different HGs. ⋯ Use of the Hill classification in clinical practice is low. There is an association of increasing HGs with increasing proportion of patients with abnormal AET. There is a high proportion of patients within HGs I and II with documented pathologic reflux and the presence of a hiatal hernia as observed on endoscopic examination. Our study suggests that endoscopic grading of the gastroesophageal junction may not adequately differentiate between normal vs abnormal reflux status, particularly for HGs I and II.

Individuals with esophageal atresia (EA) have lifelong increased risk for mucosal and structural pathology of the esophagus. The use of surveillance endoscopy to detect clinically meaningful pathology has been underexplored in pediatric EA. We hypothesized that surveillance endoscopy in pediatric EA has high clinical yield, even in the absence of symptoms. ⋯ Surveillance endoscopy uncovers high rates of actionable pathology even in asymptomatic children with EA. Based on the findings of the current study, a pediatric EA surveillance endoscopy algorithm is proposed.

The notion that gas-bloat syndrome (GBS) after magnetic sphincter augmentation (MSA) is less detrimental has not been substantiated by data. This study aimed to identify the incidence, natural history, risk factors, and impact on outcomes of GBS after MSA. ⋯ GBS affects 13.3% of patients at 1 year after MSA and substantially diminishes outcomes. However, GBS resolves spontaneously with quality-of-life improvement. Patients with preoperative bloating, high GERD-HRQL scores, or small MSA devices are at greatest risk of this complication.
