Grading criteria and assessment of surgical success in patients undergoing surgery for noninsulinoma pancreatogenous hypoglycemia.

Category Criteria Patients, N (%)
I – High surgical success (significant reduction in symptoms with no long-term complications)

  • Improvement in overall health status (EQ5D and visual scores)

  • Substantial improvement in hypoglycemic symptoms (>80% reduction in FOHS score)

  • Rare or no postoperative gastrointestinal symptoms (nausea/vomiting, diarrhea, steatorrhea)

  • No diabetes

 10 (21%)
II – Moderate surgical success (Moderate reduction in symptoms with few long-term complications)

  • Improvement in overall health status (EQ5D and visual scores)

  • Modest improvement in hypoglycemic symptoms (>40% reduction in FOHS score)

  • Few (weekly or less) new postoperative gastrointestinal symptoms (nausea/vomiting, diarrhea, steatorrhea)

  • Diet or medication-controlled diabetes

 13 (27%)
III – Minimal surgical success (Reduction in symptoms with significant long-term complications)

  • Improvement in overall health status (EQ5D and visual scores)

  • Minimal improvement in hypoglycemic symptoms (10–40% reduction in FOHS score)

  • New daily postoperative gastrointestinal symptoms (nausea/vomiting, diarrhea, steatorrhea)

  • Insulin-dependent diabetes

 13 (27%)
IV – Surgical Failure (No long-term reduction of symptoms, and overall worse quality of life)

  • Any worsening overall health status (EQ5D and visual scores)

  • Lack of long-term improvement in hypoglycemic symptoms (<10% reduction, or any worsening in FOHS score)

  • Further surgical intervention required for management of hypoglycemia (total pancreatectomy, feeding tube)
