Insights

Surgery for diffuse congenital hyperinsulinism (DCHI) in Chinese children, including subtotal and near-total pancreatectomy, showed comparable outcomes. Careful balancing of hypoglycemia control and postoperative diabetes risk is crucial for optimizing long-term results.

Area of Science:

  • Pediatric Surgery
  • Endocrinology
  • Medical Genetics

Background:

  • Diffuse congenital hyperinsulinism (DCHI) is a rare condition causing persistent hypoglycemia.
  • Medically refractory DCHI often necessitates surgical intervention.
  • Accurate assessment of pancreatic involvement is key for surgical planning.

Purpose of the Study:

  • To describe surgical indications, procedure selection, and outcomes in Chinese children with DCHI.
  • To evaluate the effectiveness of subtotal pancreatectomy (STP) and near-total pancreatectomy (NTP) in managing DCHI.
  • To analyze postoperative metabolic and neurodevelopmental outcomes.

Main Methods:

  • Retrospective summary of clinical and genetic characteristics for 27 children with DCHI.
  • Stratification into surgical (n=12) and non-surgical (n=15) groups.
  • 18F-L-DOPA PET/CT used for pancreatic assessment; Firth penalized logistic regression for exploratory analysis; Kaplan-Meier for neurodevelopmental trends.

Main Results:

  • 12 out of 27 patients (44.4%) underwent surgery (6 STP, 6 NTP).
  • ABCC8/KCNJ11 mutations were found in all tested surgical patients (8/8).
  • Hypoglycemia control was similar between STP and NTP; 16.7% of NTP patients developed postoperative diabetes; neurodevelopmental outcomes were comparable between surgical and non-surgical groups.

Conclusions:

  • Subtotal and near-total pancreatectomy are safe procedures with no major perioperative complications in this pediatric DCHI cohort.
  • Balancing hypoglycemia control with the risk of postoperative diabetes is critical when choosing resection extent.
  • Early diagnosis, prompt management, and structured follow-up are vital for optimal long-term outcomes in DCHI.
