Approximate Synonyms
- Hypergastrinemia
- Increased gastrin secretion
Clinical Information
- A disorder in which tumors of the pancreatic islet cells produce large amounts of gastrin (a hormone), leading to excess acid in the stomach and, possibly, a peptic ulcer (ulcer of the stomach or the upper part of the small intestine).
- A syndrome characterized by the presence of a gastrin-secreting tumor, usually in the pancreas or duodenum, resulting in increased gastric acidity and formation of gastric ulcers. Signs and symptoms include abdominal pain and diarrhea. It may be sporadic or a manifestation of multiple endocrine neoplasia type 1.
- A syndrome that is characterized by the triad of severe peptic ulcer, hypersecretion of gastric acid, and gastrin-producing tumors of the pancreas or other tissue (gastrinoma). This syndrome may be sporadic or be associated with multiple endocrine neoplasia type 1.
- Triad comprising intractable, sometimes fulminating atypical ulcers, extremely elevated gastic acidity, and gastrin secreting non beta islet cell tumors.
ICD-10-CM E16.4 is grouped within Diagnostic Related Group(s) (MS-DRG v39.0):
- 380 Complicated peptic ulcer with mcc
- 381 Complicated peptic ulcer with cc
- 382 Complicated peptic ulcer without cc/mcc
