Diseases of the gastrointestinal tract (gastroenterology)

Neurotensinoma: causes, symptoms, diagnosis, treatment

Neurotensinoma - individual neurotensin-producing cells (N-cells) are found in the pancreatic gastrinoma. On the predominantly neurotensin-producing tumors, there are still few reports.

Multiple endocrine adenomatosis: causes, symptoms, diagnosis, treatment

The hormone-active pancreatic tumor can be one of the manifestations of multiple endocrine adenomatosis (MEA) or multiple endocrine neoplasia (MEN).

Pancreatic carcinoid

Carcinoid pancreatic tumor occurs mainly in middle-aged and elderly people. It can be localized in any part of it. The size of the tumor varies from a few millimeters to 13-14 cm.

Glucagon - A-cell pancreatic tumor that produces glucagon, is clinically manifested by a combination of characteristic skin changes and metabolic disorders. The syndrome of glucagonoma was deciphered in 1974. S. N. Mallinson et al. In 95% of cases, the tumor is intrapancreatic, in 5% - extrapancreatic. There were only cases of solitary tumors. More than 60% of patients it malignant. Sometimes glucagonoma produces other peptides - insulin, PP.

Werner-Morrison Syndrome

Werner-Morrison syndrome is a disease that manifests itself as severe water-resistant diarrhea, hypokalemia, and gastric chlorhydria or hypochlorhydria and is also called WDHA or WDHH syndrome (Hypokalemia Achlorhydria, Hypochlorhydria).

Insulinoma

Insulinoma is the most common endocrine tumor of the pancreas. It accounts for 70-75% of hormone-active tumors of this organ. Insulinoma is solitary and multiple, in 1-5% of cases, the tumor is a component of multiple endocrine adenomatosis.

Hormone-active pancreatic tumors: causes, symptoms, diagnosis, treatment

Most hormone-active tumors of the digestive system are localized in the pancreas. This is due to the abundance of hormone-competent cells in it, from which such tumors originate.

Pancreatic sarcoma

Pancreatic sarcoma is extremely rare, to date, about 200 cases of pancreatic sarcoma have been described in specialized medical literature (judging by the statistics of a number of authors).

Pancreatic cancer: symptoms

Symptoms of pancreatic cancer are polymorphic and largely depend on the location, type and size of the tumor, its relationship to nearby organs, the duration of the disease (stage), the presence or absence of metastases. Symptoms of the initial stage of pancreatic carcinoma are rather vague: weight loss, anorexia, dyspepsia, weakness, disability; their frequency is different.

Pancreas cancer

Pancreatic cancer is found, according to various sources, in 1-7% of all cancers; more often in persons older than 50 years, predominantly in men.
