Gastrinoma is most commonly located in the gastrinoma triangle (comprising of the duodenum, pancreas and bile ducts) or in the adjacent lymph nodes. Due to the low mortality rate, it is often misdiagnosed as other diseases with similar clinical characteristics, such as a solid pseudopapillary tumor of the pancreas (SPTP). Therefore, the current study reports a rare case of gastrinoma located. Zollinger-Ellison syndrome is a complex condition in which one or more tumors form in the patient's pancreas or upper duodenum.

Operative Treatment of Gastrinoma Jason A. Castellanos Nipun B. Merchant DEFINITION Zollinger-Ellison syndrome is a rare etiology of ulcer disease that is caused by gastrin secretion of neuroendocrine tumors (gastrinomas) typically found in the duodenum and pancreas. These tumors may be sporadic or associated with multiple endocrine neoplasia type 1 (MEN-1) roendocrine cells exist in lymph nodes of the gastrinoma triangle in patients without a gastrinoma [7, 21]. The existence of primary lymph node gastrinoma as a cause of Zollinger-Ellison syndrome is, on the other hand, still controversial. In 1994, Arnold et al. analyzed 110 cases from 1982 to 1992 [22]. During surgical exploration, 2 A gastrinoma is a tumor that secretes excessive levels of the hormone gastrin and is responsible for Zollinger-Ellison syndrome (ZES). Gastrinomas are frequently associated with multiple endocrine neoplasia 1 (MEN 1) and can arise from the pancreas, stomach, duodenum, jejunum, and/or even from the lymph nodes

The gastrinoma triangle is a well-described anatomic region in which 90% of gastrinomas can typically be found. The points of the gastrinoma triangle are the junction of the pancreatic body and neck, the junction of the second and third portions of the duodenum, and the junction of the cystic and common bile ducts Fig. 1 Histology of grade 1, well-differentiated, duodenal neuroendocrine tumor (gastrinoma) from a patient with MEN1-associated ZES. a Hematoxylin and eosin stain. b Immunohistochemistry for gastrin. c Chromogranin A. d Synaptophysin. MEN1 multiple endocrine neoplasia type 1, ZES Zollinger-Ellison syndrome Once a diagnosis of ZES is suspected, the initial workup should include an evaluation. These tumors can occur outside the gastrinoma triangle and must be specifically considered. Furthermore, their discovery changes the operative approach because aggressive liver or bile duct resection is indicated, with high rates of long-term cure and survival and acceptable rates of complications

Passaro s triangle or Gastrinoma triangle is a presumptive region in the abdomen between three points: Superior - Body of Gallbladder Earlier - confluence Symptoms include abdominal pain and diarrhea. The syndrome is caused by a gastrinoma a neuroendocrine tumor that secretes a hormone called gastrin. Too much pancreatic tumors Non - functioning endocrine pancreatic tumors Insulinoma. A gastrinoma is a gastrin-secreting tumor that can occur in the pancreas, although it is most commonly found in the duodenum.

Gastrinoma is a rare tumor of non-beta cells of the pancreatic islet of Langerhans. It can lead to overproduction of gastrin hormone and causes Zollinger-Elliso gastrinoma triangle, defined by the junction of the cystic and common bile ducts, the junction of the second and third portions of the duodenum, and the junction between the neck and body of the pancreas. Gastrinomas rarely occur outside this triangle. Primary hepatic gastrinomas are extremely rare, with fewer tha Gastrinoma. Gastrinomas are neuroendocrine tumours (NETs) that start in cells that make the hormone gastrin. Most gastrinomas start in the small bowel (duodenum) and the pancreas. They are a type of functioning NET of the pancreas

The vast majority of gastrinomas are present within the gastrinoma triangle, which is composed of the porta hepatis, duodenal sweep, and pancreatic head. As surgery remains the treatment of choice, localization of the primary lesion is often challenging but essential. We present a 50-year-old man with a tentative diagnosis of Zollinger. The most common localization was the gastrinoma triangle, only in 20% of cases occurred in the peripancreatic lymph nodes. During a median follow-up of 43, 5 (range 4-194) months, all patients have remained asymptomatic. Approximately, 22% (2/9) of gastrinoma cases develop in association with multiple endocrine neoplasia type 1 gastrinoma: Definition Gastrinomas are tumors associated with a rare gastroenterological disorder known as Zollinger-Ellison syndrome (ZES). They occur primarily in the pancreas and duodenum (beginning of the small intestine) and secrete large quantities of the hormone gastrin, triggering gastric acid production that produces ulcers. They may. A gastrinoma is a tumor usually in the pancreas or duodenum (the first segment of the small intestine) that produces excessive levels of the hormone gastrin, which stimulates the stomach to secrete acid and enzymes, causing peptic ulcers. These tumors arise from cells in the pancreas that produce gastrin 80% of these tumors are found within the hypothetical gastrinoma triangle (confluence of the cystic and common bile ducts superiorly, junction of the second and third portions of the duodenum inferiorly, and junction of the neck and body of the pancreas medially).; Duodenal tumors are smaller, slower-growing, and less likely to metastasize than pancreatic lesion

Tumor distribution • Majority of the gastrinoma occur in the pancreas. • Over 80% of the tumors are found within the hypothetical gastrinoma triangle • Duodenal tumors Constitute the most common non pancreatic lesion about 50- 70% • Less common extra pancreatic sites include stomach , bones, ovaries, heart, lymph nodes. • 60% of the. The majority of gastrinomas are identified within the gastrinoma triangle, which consists of the duodenum, pancreatic head and hepatoduodenal ligament . The tumor should be located prior to surgery, and ultrasonography is the standard choice of diagnostic technique due to its convenience and cost-effectiveness; however, the sensitivity of the. A gastric pH level higher than 3.0 excludes gastrinoma. A BAO of greater than 15 mEq/h and even as high as 150 mEq/h is indicative of gastrinoma. In patients with intermediate gastrin levels (150-1000 pg/mL) and acid secretion, the secretin stimulation test can help diagnose the presence of gastrinoma Gastrinoma is most commonly located in the gastrinoma triangle (comprising of the duodenum, pancreas and bile ducts) or in the adjacent lymph nodes. Due to the low mortality rate, it is often misdiagnosed as other diseases with similar clinical characteristics, such as a solid pseudopapillary tumo Gastrinomas usually occur in the so‐called gastrinoma triangle, defined by the junction of the cystic and common bile ducts, the junction of the second and third portions of the duodenum, and the junction between the neck and body of the pancreas.

Furthermore, since the jejunum is not located within the gastrinoma triangle, this unexpected localization makes the diagnosis difficult. A number of tests are used to localize gastrinomas.

Gastrin-secreting neoplasms were first described by Zollinger and Ellison in 1955. These unusual neoplasms can be either benign or malignant. The diagnosis of the Zollinger-Ellison syndrome depends on an increased fasting serum gastrin concentration (>100pg/ml), increased basal acid output (>10mEq/l), and an abnormal secretin test (increase of >200pg/ml in serum gastrin concentration after 2U.
