Final answer:
If an insulinoma is unresectable, medical management with medications like diazoxide or octreotide, or ablation techniques such as radiofrequency ablation or ethanol injection can be effective in controlling the symptoms or destroying the tumor.
Step-by-step explanation:
If an insulinoma is unresectable, meaning it cannot be surgically removed, there are other treatment options available. One possible treatment is medical management with medication such as diazoxide or octreotide. These medications can help control the symptoms of hypoglycemia caused by the excess insulin production from the tumor. Another option is to use ablation techniques, such as radiofrequency ablation or ethanol injection, to destroy the tumor cells. These techniques can be effective in shrinking or destroying the tumor.
