Barrett's esophagus, esophagus adenocarcinoma

There is no reliable data on the incidence of adenocarcinoma in Barrett's esophagus, but it has been proven that the risk of the disease increases in this case by 20-40 times. Presumably, the mechanisms of carcinogenesis are similar to those in bowel cancer - chronic damage to the epithelium and cell proliferation lead to genetic alterations and, ultimately, to the neoplastic process. Progression of the tumor, as in the case of ulcerative colitis, occurs gradually. The presence of dysplasias indicates a high risk of carcinogenesis and serves as a good indicator for screening studies. Detection of dysplasias, especially highly differentiated ones, is an indication for esophagectomy, since there is a high risk of malignancy.

Barrett's esophagus, esophagus adenocarcinoma

  1. BEAUTIFUL DIGITAL TUMORS
    Classification 1. Solitary myomas. - Acquired neoplasia. 2. Nodular multiple myomas. 3. Common leiomyomatosis 4. Polyps: adenomas, lipomas, etc. 5. Cysts. Diagnostic criteria Dysphagia, dyspepsia; pain along the esophagus. Examples of the formulation of the diagnosis 1. Solitary myoma of the esophagus. 2. Nodular multiple myomas of the esophagus. 3
  2. Esophageal carcinoma
    The two main types of tumors of the esophagus - squamous carcinoma and adenocarcinoma - have a different etiology and their own characteristics of the course, therefore, should be considered separately. The unequal incidence of squamous cell carcinoma in different countries has long puzzled scientists. It is believed that differences in the frequency of its occurrence depend on the dissimilarity of the action of one or several
  3. Esophageal stricture
    - narrowing of the esophagus associated with congenital or acquired factors Classification of cicatricial narrowing of the esophagus (H. L. Ratner, V. And Belokonev, 1982). By etiology: burns with acids, alkalis, other burns. By time of obstruction: early (3-4 weeks), late (after 1 month) According to the mechanism of development and clinical manifestations: A. Functional obstruction of the esophagus 1.
  4. Diseases of the esophagus
    1. What symptom is most often observed in diseases of the esophagus? Regurgitation. 2. How does regurgitation differ from reflux? Regurgitation is a passive, retrograde movement of swallowed food to the upper esophageal sphincter; as a rule, food does not have time to get into the stomach. Most often, regurgitation results from esophageal peristalsis, esophageal obstruction or asynchronous
  5. DIETARY DIVERTICULES
    - blindly ending process or protrusion of an organ. LINKER DIVERTICULES - localized on the back of the pharynx and esophagus. Classification of esophagus diverticulums, diverticulitis (according to Yusbasic, 1961). By localization: 1. Faringo-esophagal (Tsenker), 2. Bifurcation. 3. Epiphrenal. Largest diverticulum: Stage I - protrusion of the esophageal mucosa
  6. ESOPHAGUS
    The esophagus (esophagus) is a cylindrical tube 25-30 cm long that connects the pharynx to the stomach. It begins at the level of the VI cervical vertebra, passes through the chest cavity, the diaphragm, and flows into the stomach to the left of the X — XI thoracic vertebra. There are three parts of the esophagus: cervical, thoracic and abdominal. The cervical part is located between the trachea and the spine at the level of the VI cervical and up to the second thoracic
  7. Esophagus features
    The esophagus in young children has a spindle shape, it is narrow and short. In a newborn, its length is only 10 cm, in children at 1 year of life - 12 cm, at 10 years old - 18 cm. Its width, respectively, is 7 years old - 8 mm, at 12 years old - 15 mm. On the esophageal mucosa there are no glands. It has thin walls, weak development of muscle and elastic tissues, it is well supplied with blood.
  8. PEPTIC Ulcers of the esophagus
    - a type of esophagitis, often combined with cholelithiasis and gastroduodenal ulceration, accompanied by cardia failure, caused most often by hernia of the esophageal opening of the diaphragm. Diagnostic criteria 1) Sternum pain, aggravated after eating, when swallowing, when lying down; 2) dysphagia; 3) heartburn, belching, regurgitation of gastric contents; 4) complications:
  9. Esophagus (problems)
    The esophagus is the part of the digestive tract between the larynx and the stomach. The esophagus passes through the neck, chest and diaphragm. It is characterized by the following diseases; DIVERTICULITIS, HERNIA, OR CONGENITAL DEFECTS. Pain in the esophagus can be caused by a foreign object in it or by the feeling that there is a foreign object in it. Since the esophagus is the beginning of the digestive tract,
  10. Anesthesia for operations on the esophagus
    General Information Operations on the esophagus are performed on tumors, gastroesophageal reflux and motility disorders (achalasia). Operations include endoscopy, esophageal dilatation, cervical esophagiomyotomy, open or thoracoscopic distal esophagomyotomy, esophagectomy, and en block esophagus resection. Among the tumors of the esophagus most common is squamous cell carcinoma, less often adenocarcinoma,
  11. Diseases of the esophagus
    The normal esophagus is a hollow, well stretchable muscular tube that extends from the level of the VI cervical vertebra to the level of the XI or XII thoracic vertebrae. These levels correspond to the transition of the pharynx to the esophagus and the esophago-gastric junction. In newborns, the esophagus is 10–12 cm long, and in adults it is 23–25 cm. There are three anatomical narrowings of the esophagus, which persist for
  12. Clinical anatomy and topography of the esophagus
    The esophagus (oesophagus) is a continuation of the pharynx from the level of the lower edge of the cricoid cartilage (VI cervical vertebra). The esophagus passes into the stomach at level XI of the thoracic vertebra. The esophagus is a tube 24-25 cm long, flattened in the anteroposterior direction. Three sections are distinguished in the esophagus: 1. Cervical. 2. Thoracic. 3. Abdominal. In the cervical and early thoracic
  13. FOOD CLUTCH
    Most often found in kittens, which during the game can swallow plastic or rubber toys or their pieces. In adult cats, blockage of the esophagus is extremely rare, usually as a result of excessively greedy eating of food. Symptoms: the first signs of obstruction of the esophagus are restless behavior, the cat turns its head, twitches, scratches its mouth, coughs, can be observed
