About Insulinoma
Key Highlights
-
High cure rate with complete surgical removal, often resolving hypoglycemia permanently.Utilizes advanced, minimally invasive diagnostic techniques like endoscopic ultrasound for precise tumor localization.Multidisciplinary approach involving endocrinologists, surgeons, and radiologists ensures comprehensive care.Significantly improves quality of life by eliminating unpredictable and dangerous episodes of low blood sugar.
Who is this surgery for?
- Recurrent episodes of neuroglycopenic symptoms (confusion, dizziness, seizures, loss of consciousness) and adrenergic symptoms (sweating, palpitations, tremors) related to fasting or exercise.
- Documented Whipple's Triad: symptoms of hypoglycemia, low plasma glucose measured at the time of symptoms, and relief of symptoms upon raising blood sugar.
- Confirmed biochemical evidence of endogenous hyperinsulinism (elevated insulin, C-peptide, and proinsulin during hypoglycemia).
- Positive localization of a pancreatic tumor on imaging studies (CT, MRI, or endoscopic ultrasound).
How to prepare
- Undergo a supervised diagnostic fast (usually 72 hours) in a hospital setting to safely document hypoglycemia.
- Complete all necessary imaging studies (CT, MRI, EUS) to map the tumor's exact size and location.
- Discontinue any medications that might affect blood sugar levels, as advised by your endocrinologist.
- For scheduled surgery, follow standard pre-operative instructions, including fasting and necessary blood work.
- Discuss your full medical history, including all medications and allergies, with your care team.
Risks & possible complications
- Surgical risks include bleeding, infection, and damage to surrounding organs like the spleen or bile ducts.
- Specific to pancreatic surgery: potential for pancreatic fistula (leakage of pancreatic fluid), pancreatitis, or diabetes if a significant portion of the pancreas is removed.
- Anesthesia-related risks.
- Rare recurrence of the tumor or, in malignant cases, potential for metastasis.
- Complications from diagnostic procedures, such as perforation from endoscopic ultrasound (very rare).
Recovery & hospital stay
- Initial hospital stay is required post-surgery for pain management, monitoring for complications, and ensuring stable blood sugar levels.
- Blood glucose levels are closely monitored as the body adjusts to normal insulin production.
- A temporary drain may be placed near the surgical site to remove excess fluid.
- Diet will progress from clear liquids to solid foods as bowel function returns.
- Follow-up appointments are crucial to check surgical wounds, monitor glucose control, and assess for any long-term needs like enzyme replacement if pancreatic function is affected.
-
Typical hospital stay: 5-10 days
-
Expected recovery time: 4-6 weeks

Rahul Chopra, a 42-year-old software engineer...
Rahul Chopra, a 42-year-old software engineer and father of two, had always been healthy and active. Over the past year, he began experiencing terrifying episodes of confusion, sweating, and palpitations, often mid-morning or during long meetings. He once collapsed at work. His primary care doctor found nothing wrong initially. The episodes became more frequent and severe. His wife noticed he was often irritable and pale before an episode, which improved dramatically after he ate something sweet. After a particularly bad episode where he was found disoriented in a parking lot, he was referred to an endocrinologist. The endocrinologist, suspecting an insulinoma, admitted him for a supervised 72-hour fast. Rahul's blood sugar plummeted, and his insulin levels were inappropriately high, confirming the diagnosis. A CT scan located a small tumor on his pancreas. He underwent a laparoscopic enucleation, a minimally invasive surgery to remove the tumor. The surgery was successful. Post-procedure, he spent a few days in the hospital recovering. He had to monitor his blood sugar closely as his body readjusted, but within weeks, the debilitating episodes stopped completely. Emotionally, the year of unexplained 'spells' had been a nightmare, filled with fear for his safety and his ability to provide for his family. He felt dismissed and anxious. After the diagnosis and successful surgery, he felt immense relief and validation. He regained his confidence and energy, feeling like he had his life back.
