🔍 Key Findings
- Surgical excision of insulinomas resulted in euglycemia or hyperglycemia in 90% of cats immediately post-op.
- 18/20 cats (90%) survived to hospital discharge, with a median survival time of 863 days.
- Younger age, metastasis at surgery, tumor invasion, and lower glucose levels were negative prognostic factors.
- Two cats had stage III disease with metastasis; one lived 413 days post-op, suggesting some benefit to surgery even in advanced disease.
- Postoperative hypoglycemia and seizure activity were associated with poorer outcomes; one cat euthanized due to seizures despite euglycemia.
- Median disease-free interval (DFI) was 1052 days; for cats with metastasis, DFI dropped to 93 days.
- Partial pancreatectomy was performed in 11 cats, nodulectomy in 10, and enucleation in 1; method of resection not linked to outcome.
- Postoperative complications occurred in 25% of cats; most were manageable with supportive care.
