Study Notes

Pancreatic Endocrine Neoplasms (PET)

Pancreatic Neuroendocrine Tumors (pNET) include both functioning and nonfunctioning variants.
Nonfunctioning tumors present with nonspecific and variable symptoms.
Approximately 1 in 10,000 nonfunctioning pancreatic tumors is malignant.
Associated mortality rate is 2-10%, with morbidity around 30-40%.
Management includes surgical resection for localized tumors; splenectomy may be required for tumors in the body and tail.

Diagnosis and Surveillance

Primary goal is to identify cysts that have a significant risk of malignancy.
MRI with MRCP is the preferred imaging modality for assessment.
Endoscopic Ultrasound (EUS) is recommended for high-risk cysts.
CT scans are also utilized for diagnostic purposes.

Cystic Neoplasms

Cystic neoplasms are often evaluated in the context of pancreatic lesions.
Different imaging and endoscopic techniques are essential in the management of cystic pancreatic neoplasms.

Chronic Pancreatitis

A chronic condition characterized by inflammation of the pancreas.
Multifactorial etiology includes alcohol consumption (38-94%), smoking, gallstones, and hereditary factors.
Treatment can be complex due to its highly variable presentation.

Specific Tumors in Pancreatic Endocrine Neoplasms

Insulinoma: The most common pNET; about 90% are benign, while 10% are malignant. Diagnosed using Whipple’s triad, which includes fasting hypoglycemia, elevated insulin and C-peptide levels.
Gastrinoma, VIPoma, Glucagonoma, and Somatostinoma are other types of functional pancreatic endocrine tumors with specific hormonal secretions and syndromes.
Nonfunctioning pancreatic endocrine tumors do not cause a specific clinical syndrome.

Surgical Procedures in Management

Endoluminal cystogastrostomy can be a management option for certain pancreatic conditions.
Roux-en-Y pancreaticojejunostomy is a surgical technique used in specific cases, often in the context of pancreatic surgery.
