Dumping Syndrome in Children: A Narrative Review

Area of Science:

• Gastroenterology
• Pediatric Surgery
• Endocrinology

Background:

• Dumping syndrome (DS) is a frequent complication following gastric, esophageal, and bariatric surgery.
• It involves rapid gastric emptying, leading to early gastrointestinal/vasomotor symptoms and late reactive hypoglycemia.
• DS in children, often post-obesity or congenital defect surgery, is under-recognized and can cause cognitive deficits.

Purpose of the Study:

• To provide a comprehensive review of the latest literature on dumping syndrome in children.
• To highlight clinical and scientific aspects, including quality of life, pathophysiology, diagnosis, prevalence, and treatment.

Main Methods:

• Literature review focusing on recent studies and clinical data.
• Analysis of diagnostic methods including symptom-based questionnaires, plasma glucose measurement, and gastric emptying studies.
• Evaluation of treatment strategies, encompassing dietary modifications, supplements, medications, and surgical interventions.

Main Results:

• Early DS symptoms include nausea, diarrhea, and flushing; late symptoms involve hypoglycemia, sweating, and confusion.
• Pathophysiology differs between early (rapid transit) and late (hyperinsulinemia) dumping.
• Effective management relies on dietary adjustments, with medications like alpha-glycosidase inhibitors and somatostatin analogs used.

Conclusions:

• Dumping syndrome requires a multidisciplinary approach for diagnosis and management, particularly in pediatric populations.
• Early screening and identification in children are crucial to prevent long-term complications like cognitive impairment.
• Further research is essential to refine understanding and optimize treatment strategies for DS in children.
