Childhood gastroesophageal reflux disease.

The diagnosis of gastroesophageal reflux (GERD) in children is a complex and challenging task that requires meticulous attention to detail and a deep understanding of pediatric physiology. It is absolutely crucial to distinguish between the benign chalasia of infancy and the more serious pathologic GERD. Recent advancements have shown that Combined Multichannel Intraluminal Impedance and pondus hydrogenii measurement offer superior diagnostic accuracy. The role of nuclear scans in diagnosing GERD remains an area of ongoing research. The management of GERD in children follows a stepwise approach, starting with medical therapy and progressing to surgical intervention if necessary.
