  Zollinger-Ellison syndrome is a condition in which one or more tumors grow in the pancreas or small intestine. The tumors, called gastrinomas, produce large amounts of the hormone gastrin. Gastrin causes the stomach to produce too much acid, which leads to peptic ulcers. High gastrin levels also can cause diarrhea, belly pain and other symptoms. […] The exact cause of Zollinger-Ellison syndrome isn’t known. But the pattern of events that occurs in Zollinger-Ellison syndrome typically follows the same sequence. The syndrome begins when one or more tumors form in the pancreas or a part of the small intestine called the duodenum. […] The tumors that form with Zollinger-Ellison syndrome are made up of cells that secrete large amounts of the hormone gastrin. For this reason, they are sometimes called gastrinomas. Increased gastrin causes the stomach to make far too much acid. The excess acid then leads to peptic ulcers and sometimes to diarrhea.

  Zollinger-Ellison syndrome is a condition in which the body produces too much of the hormone gastrin. Most of the time, a small tumor (gastrinoma) in the pancreas or small intestine is the source of the extra gastrin in the blood. […] Zollinger-Ellison syndrome is caused by tumors called gastrinomas. These growths are most often found in the head of the pancreas and the upper small intestine. High levels of gastrin cause production of too much stomach acid. […] Gastrinomas may occur as single tumors or several tumors. One half to two thirds of single gastrinomas are cancerous (malignant) tumors. These tumors often spread to the liver and nearby lymph nodes. […] Many people with gastrinomas have several tumors as part of a condition called multiple endocrine neoplasia type I (MEN I). Tumors may develop in the pituitary gland (brain) and parathyroid gland (neck) as well as in the pancreas.

  https://my.clevelandclinic.org/health/diseases/17960-zollinger-ellison-syndrome

  Zollinger-Ellison syndrome is a rare condition that causes tumors called gastrinomas to grow in your pancreas or intestine. Gastrinomas release the hormone gastrin, which triggers your stomach to produce gastric acid. Too much stomach acid leads to ulcers and other complications. Some gastrinomas are also cancerous. […] Most cases of Zollinger-Ellison syndrome happen sporadically (for no known reason). About 25% of people with this condition have MEN Type 1. MEN stands for multiple endocrine neoplasia. MEN is a rare inherited disorder that affects glands in your endocrine system. […] Zollinger-Ellison syndrome can be life-threatening. For example, a gastrinoma tumor that blocks your duodenum can make it rupture. The tumor can spread to your liver. Large amounts of gastric acid may lead to severe gastrointestinal bleeding. […] Surgery to remove cancerous gastrinomas may cure the condition. But a cure depends on removing all cancerous cells in your body. If surgery is successful, you’ll need to take medication to manage gastric acid for the rest of your life.

  https://www.cancercenter.com/cancer-types/pancreatic-cancer/types/gastrinomas

  Gastrinomas are a rare form of pancreatic neuroendocrine tumor (NET) that begins in the neuroendocrine cells of the pancreas. […] Different types of neuroendocrine cells release different types of hormones. For example, gastrinomas release gastrin. […] When working correctly, gastrin is released in small amounts after you eat, but gastrinomas may trigger a condition called Zollinger-Ellison syndrome, in which the stomach produces excess acid, ulcers, bleeding and severe reflux. […] Zollinger-Ellison syndrome (ZES) occurs when gastrinomas cause the stomach to produce too much acid. […] Approximately 20 percent of patients diagnosed with Zollinger-Ellison syndrome also have multiple endocrine neoplasia type 1 (MEN1), a rare genetic condition, according to NIDDK. […] While the uncontrolled division and reproduction of gastrin-producing cells contributes to the occurrence of gastrinomas, research to identify their exact cause is ongoing. […] However, its known that an inherited genetic condition called multiple endocrine neoplasia type 1 (MEN1) syndrome causes 25 percent to 30 percent of all gastrinomas, according to The National Pancreas Foundation.

  ZES is primarily caused by the growth of gastrinomas, usually benign, non-cancerous tumours that develop in the pancreas. […] The excessive gastrin production caused by these tumours is responsible for developing peptic ulcers and other gastrointestinal complications. […] In some cases, the cause of ZES is unknown. However, research suggests that genetic mutations may play a crucial role in the spreading the condition. In particular, mutations in a gene called MEN1 have been associated with the development of ZES. MEN1 is a tumour suppressor gene that helps prevent the growth of tumours in the pancreas and other organs. When this gene is mutated, it can lead to the development of pancreatic gastrinoma and other types of tumours. […] Zollinger-Ellison Syndrome (ZES) is a rare condition caused by the formation of tumours that produce excessive amounts of gastrin, a hormone that stimulates acid production in the stomach. While the exact cause of ZES is unknown, certain factors can raise a person’s risk of developing the condition.

  Zollinger-Ellison syndrome (ZES) associated with pancreatic or duodenal gastrinoma is characterized by gastric acid hypersecretion, which typically leads to gastroesophageal reflux disease, recurrent peptic ulcers, and chronic diarrhea. […] The critical step for the diagnosis of ZES is represented by the initial clinical suspicion. Hypergastrinemia is the hallmark of ZES; however, hypergastrinemia might recognize several causes, which should be ruled out in order to make a final diagnosis. Gastrin levels 1000 pg/mL and a gastric pH below 2 are considered to be diagnostic for gastrinoma; some specific tests, including esophageal pH-recording and secretin test, might be useful in selected cases, although they are not widely available. […] Zollinger-Ellison syndrome (ZES) was firstly described in 1955 as associated with a neuroendocrine neoplasm (NEN) capable of ectopic gastrin secretion (namely gastrinoma), resulting in gastric acid hypersecretion, which typically leads to gastroesophageal reflux disease (GERD), recurrent peptic ulcers, and chronic diarrhea.

  Zollinger-Ellison syndrome is a condition in which neuroendocrine gastrinomas form in the pancreas or duodenum. […] About 60% of gastrinomas are malignant. The gastrinomas secrete gastrin, which causes the stomach to produce too much acid, and this leads to peptic ulcers in the stomach and duodenum. […] Drs Zollinger and Ellison theorized that a hormone secreted from these tumors was causing the gastric acid output that resulted in the peptic ulcer syndromes. […] In 1960, Dr Roderic Gregory and Dr Hilda Tracy extracted a gastrin-like substance from the pancreas of a patient with Zollinger-Ellison syndrome, establishing gastrin as the hormone that causes the syndrome.

  ZES is a rare condition that affects the digestive tract. Its possible to only have one tumor, but more common for there to be multiple ones. About half of these tumors are noncancerous, or benign. Experts arent exactly sure what causes ZES. In most cases, the disorder appears for no obvious reason. In 25 percent of cases, its association with an inherited, tumor-causing condition called multiple endocrine neoplasia type 1 (MEN1). […] More research is needed to better understand this condition.

  One of the common risk factors for ZES is having a family history of the condition or multiple endocrine neoplasia type 1 (MEN1), a genetic disorder that can cause tumours in various endocrine glands, including the pancreas. Individuals with a family history of these conditions should know the increased risk and discuss appropriate screening with their healthcare provider. […] In some cases, the cause of ZES is unknown. However, research suggests that genetic mutations may play a crucial role in the spreading the condition.

• #2 Zollinger-Ellison Syndrome (ZES) vs. Gastrinoma

  https://www.healthline.com/health/zollinger-ellison-syndrome-vs-gastrinoma

  Zollinger-Ellison syndrome (ZES) is a health condition that results from having a gastrinoma, or gastric tumor, that increases the production of stomach acid. […] Gastrinoma can develop from a mutation in neuroendocrine cells. About 75% to 80% of people develop it sporadically, while 20% to 30% of people develop it due to a MEN-1 mutation. MEN-1 also makes it more likely a person will develop multiple tumors. […] A gastrinoma is a type of tumor that secretes gastric acid, which can cause chronic diarrhea and acid reflux symptoms.

  Zollinger-Ellison syndrome (ZES) is caused by a nonbeta islet cell, gastrin-secreting tumor of the pancreas that stimulates the acid-secreting cells of the stomach to maximal activity. […] The symptoms of Zollinger-Ellison syndrome (ZES) are due to hypergastrinemia, it causes hypertrophy of the gastric mucosa, leading to increased numbers of parietal cells and increased acid output. […] Gastrin also stimulates acid secretion, resulting in increased basal acid secretion. This excessive acid secretion leads to gastrointestinal mucosal ulceration. It also causes diarrhea and malabsorption. […] Malabsorption in ZES usually due to Direct mucosal damage due to acid, Inactivation of pancreatic enzymes due to acidic pH (pancreatic enzyme works in Alkaline pH), Precipitation of bile salts due to acidic pH.

  The management of gastrinoma and ZES includes both a proper medical treatment for symptoms relief and surgery with curative intent whenever feasible. […] The role of surgery in the treatment of gastrinoma has changed completely from the introduction of PPIs in the 1980s. […] Surgical removal of the primary tumor (and possibly its metastases) with curative intent should be, indeed, always performed. […] The therapy for syndrome control is based on PPI, which are highly effective drugs and considered the drugs of choice for suppressing acid secretion.
