Techniques in pediatric surgery: congenital hyperinsulinism.

Area of Science:

• Pediatric Surgery
• Endocrinology
• Genetics

Background:

• Congenital hyperinsulinism (CHI) is a rare genetic disorder characterized by excessive insulin secretion.
• Management strategies vary significantly based on the subtype of CHI: focal, diffuse, or atypical.
• Surgical intervention is a key treatment modality, but its success is highly dependent on accurate diagnosis and surgical technique.

Purpose of the Study:

• To delineate distinct surgical strategies for focal, diffuse, and atypical congenital hyperinsulinism.
• To emphasize the importance of accurate preoperative localization and tailored surgical techniques for optimal patient outcomes.
• To guide clinical decision-making regarding the preferred treatment modality for different CHI subtypes.

Main Methods:

• Review of surgical techniques and outcomes for congenital hyperinsulinism.
• Emphasis on PET-CT guided resection for focal CHI.
• Discussion of medical management preference for diffuse CHI and cautious surgical considerations for atypical CHI.

Main Results:

• Focal CHI can be cured with confined, localized, and parenchyma-sparing resections guided by PET-CT.
• Surgical therapy for diffuse CHI yields unpredictable results, with cure being exceptional.
• Atypical CHI management requires careful assessment to avoid excessive resection and potential diabetes induction.

Conclusions:

• A distinct surgical strategy is essential for each type of congenital hyperinsulinism.
• PET-CT guided focal resection offers a curative approach for focal CHI.
• Medical therapy is increasingly preferred for diffuse CHI, while atypical CHI requires individualized surgical planning to balance cure and complication risks.
