Does Gastrinoma cause secretory diarrhea?
Gastrinomas are neuroendocrine tumors characterized by the secretion of gastrin with resultant excessive gastric acid production causing severe peptic ulcer disease and diarrhea, a combination referred to as the Zollinger-Ellison syndrome (ZES).
Is Zollinger-Ellison a Gastrinoma?
What causes Zollinger-Ellison syndrome? ZES is caused by tumors, called gastrinomas. The tumors cause the release of too much stomach acid. The extra acid can cause painful peptic ulcers inside the lining of your stomach and intestines.

Can Gastrinoma be seen on CT scan?
CT scans help detect 38-75% (with a mean of 50%) of extrahepatic gastrinomas, while 42-76% of hepatic metastases are seen on CT scans. The detection rate is higher for gastrinomas located in the pancreas or for larger tumor sizes (30% for 1- to 3-cm tumors compared to greater than 95% for tumors larger than 3 cm).
In which organ is gastrinoma usually found?
A gastrinoma is a gastrin-secreting tumor usually found in the pancreas or duodenum. Duodenal wall tumors are frequently small and multiple. Sporadic tumors occurring in the pancreas tend to be solitary and have a greater malignant potential as compared to duodenal gastrinomas.
