Introduction

Gastrinomas are rare tumors that develop in the pancreas or the duodenum, the first section of the small intestine. These tumors might appear as a single tumor or a cluster of tumors. They start in the cells that make gastrin, a hormone that controls the secretion of gastric acid. When you have a gastrinoma, your body produces a lot of gastrin, which causes your stomach acid to rise. Ulcers in the stomach and small intestine can arise as a result of this greater amount. Gastrinomas are benign or malignant tumors. According to the Center for Pancreatic and Biliary Diseases, more than 60% of gastrinomas are malignant [1].

Peptic ulcer disease (PUD) with several recurrent and persistent ulcers, often in odd sites, is the earliest manifestation due to the physiological action of gastrin (>1000 pg/mL), resulting in excessive production of acid into the stomach. The Zollinger-Ellison syndrome is a group of symptoms caused by a gastrinoma. Diarrhea is widespread as a result of the significant amount of hydrochloric acid in the stomach and the direct influence of gastrin on the small bowel [2].

Multiple Endocrine Neoplasia (MEN-1) is a rare autosomal-dominant disorder. MEN-1 is linked to a variety of endocrine tumors, the most common of which arise in the parathyroid glands, pituitary, and pancreas. Neuroendocrine tumors have a high penetrance rate, ranging from 70% to 100%. At the age of 50, half of all MEN-1 patients will develop a pancreatico-duodenal neuroendocrine tumor. The majority will start as nonfunctioning neuroendocrine tumors or insulinomas in the pancreas. A gastrinoma is a gastrin-secreting neuroendocrine tumor that affects 42 percent of individuals (range 20–61 percent). In contrast to random gastrinomas, which mostly occur in the pancreas, the majority of MEN-1 gastrinomas arise in the duodenum. Duodenal gastrinomas are small, usually less than 1 cm in diameter, numerous, Gastrinomas in the pancreas linked with MEN-1 are extremely rare, as are gastrinomas in other unusual extra-pancreatic, extra-duodenal locales [3].

The pancreas is a large gland responsible for the production of digestive fluids and hormones. The juices pass into the duodenum through a tube called the pancreatic duct. The initial segment of the small bowel is the duodenum. The bile duct connects the duodenum to the liver and pancreas through another duct. The bile duct meets the duodenum directly adjacent to the pancreatic duct, coming down from the gallbladder and liver [4].

Neuroendocrine tumors (NETs) are malignancies that begin in neuroendocrine cells and spread throughout the body. Neuroendocrine cells can be found in most of our body's organs, including the pancreas. There are several forms of pancreatic NETs. They are usually divided into two categories: functional and nonfunctional NETs. Insulinoma, gastrinoma, somatostatinoma, glucagonoma, and VIPoma are the five basic forms of functional pancreatic NETs. Pancreatic NETs are uncommon and require treatment that differs from that of pancreatic cancer [5].

Gastrinomas are uncontrolled divisions of gastrinproducing cells. Although there may be a hereditary relationship, the actual cause of this illness is unknown. Gastrinomas can occur at any time for unexplained reasons. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDKD) trusted source, about 25 to 30 percent of gastrinomas are linked to a hereditary genetic condition known as Multiple Endocrine Neoplasia type 1 (MEN1). The growth of tumors in hormone-producing glands is a symptom of this genetic illness. Higher hormone levels, kidney stones, diabetes, muscle weakness, and fractures are all possible MEN1 symptoms. The doctor treats gastrinoma, depends on the location of tumors cells and if they've migrated to other places of the body of a person. The primary treatment is surgery, which has the goal of removing cancer from the body and curing the condition [5].
