Summary
Real-time intraoperative ultrasound effectively locates insulinomas, even small ones, by visualizing them as distinct hypoechoic masses within the pancreas. This technique aids surgeons in identifying these tumors during operations.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Medical Imaging
Context:
- Insulinomas are rare neuroendocrine tumors of the pancreas causing hypoglycemia.
- Accurate intraoperative localization is crucial for successful surgical resection.
- Minimally invasive techniques are sought to improve surgical outcomes.
Purpose:
- To evaluate the efficacy of real-time intraoperative ultrasound for localizing insulinomas.
- To demonstrate the sonographic characteristics of insulinomas during surgery.
- To assess the utility of ultrasound as an adjunct for occult insulinoma detection.
Summary:
- Intraoperative ultrasound was used to scan the pancreas in three cases of insulinoma.
- Small, palpable insulinomas appeared as well-defined, hypoechoic encapsulated masses.
- The pancreatic duct and splenic vessels were identifiable, aiding spatial orientation.
Impact:
- Real-time intraoperative sonography is a simple and effective adjunct for localizing occult insulinomas.
- This technique can improve surgical precision and reduce operative time.
- High-resolution ultrasound enhances the ability to differentiate tumors from normal pancreatic tissue.
