Zollinger–Ellison syndrome (Z-E syndrome) is a disease in which tumors cause the stomach to produce too much acid, resulting in peptic ulcers. Symptoms include abdominal pain and diarrhea. The syndrome is caused by a gastrinoma, a neuroendocrine tumor that secretes a hormone called gastrin. Too much gastrin in the blood (hypergastrinemia) results in the overproduction of gastric acid by parietal cells in the stomach. Gastrinomas most commonly arise in the duodenum, pancreas or stomach.In 75% of cases Zollinger–Ellison syndrome occurs sporadically, while in 25% of cases it occurs as part of an autosomal dominant syndrome called multiple endocrine neoplasia type 1 (MEN 1). Signs and symptoms
Patients with Zollinger–Ellison syndrome may experience abdominal pain and diarrhea. The diagnosis is also suspected in patients who have severe ulceration of the stomach and small bowel, especially if they fail to respond to treatment. Chronic diarrhea, including steatorrhea (fatty stools)
Pain in the esophagus, especially between and after meals at night
Nausea
Wheezing
Vomiting blood
Malnourishment
Loss of appetite
MalabsorptionGastrinomas may occur as single tumors or as multiple small tumors. About one-half to two-thirds of single gastrinomas are malignant tumors that most commonly spread to the liver and to lymph nodes near the pancreas and small bowel. Nearly 25 percent of patients with gastrinomas have multiple tumors as part of a condition called multiple endocrine neoplasia type 1 (MEN 1). MEN I patients have tumors in their pituitary gland and parathyroid glands, in addition to tumors of the pancreas.
