Endoscopic findings of esophagogastric junction in children

Area of Science:

• Pediatric Gastroenterology
• Esophageal Pathology

Background:

• Esophagogastric landmarks and palisade vessels are consistent in children and adults.
• Barrett's esophagus (BE) in children is understudied, with suspected incidence ranging from 0.25-1.4% in EGDs, up to 9.7% in GERD patients.
• BE may have congenital and acquired components, with multilayered epithelium (ME) potentially linked to intestinal metaplasia.

Purpose of the Study:

• To investigate the role of multilayered epithelium (ME) in pediatric Barrett's esophagus (BE).
• To understand the progression of short-segment BE (SSBE) to long-segment BE (LSBE) in children.
• To highlight the need for epidemiological data on pediatric esophagogastric junction (EGJ) and BE, especially in children with reflux symptoms.

Main Methods:

• Review of existing literature on pediatric BE and esophagogastric junction (EGJ) morphology.
• Analysis of potential associations between multilayered epithelium (ME) and intestinal metaplasia in children.
• Discussion of the transition from short-segment BE (SSBE) to long-segment BE (LSBE).

Main Results:

• Palisade-shaped vessels are present in infant esophageal mucosa.
• Multilayered epithelium (ME) characteristics in children with BE are not fully understood.
• Mechanisms of SSBE to LSBE progression in pediatric populations require further investigation.

Conclusions:

• Further research is crucial for understanding pediatric EGJ and BE, particularly in children with GERD.
• Improved diagnostic and therapeutic strategies for GERD-related disorders in adulthood may stem from better pediatric EGJ and BE insights.
• Reliable epidemiological data is needed to advance the study of pediatric BE and EGJ.
