Changes in the oral mucosa in diseases of the gastrointestinal tract

Stomach ulcer, its types and stages

Gastric ulcer (hereinafter referred to as PUD) is a disease in which a mucosal defect occurs and the submucosal layer may be affected. This is a chronic disease that occurs in waves, with periods of exacerbation and remission.

An ulcer can be localized in different parts of the stomach:

• subcardial and cardiac - in the upper part;
• antrum - in the lower section;
• in the body - in the middle part;
• in the pyloric canal - at the transition to the duodenum.

The size of the ulcer is:

• small - up to 5 mm in diameter;
• medium - in diameter 6-19 mm;
• large - 20-30 mm in diameter;
• gigantic - more than 30 mm in diameter.

There are also ulcers associated with the bacterium Helicobacter pylori (hereinafter referred to as HP) and those not associated with it.

The disease occurs in several stages:

• exacerbations - the occurrence of a defect in the mucous membrane;
• scarring - the formation of connective tissue at the site of the ulcer;
• remission - healing of the defect.

The stage of cicatricial and ulcerative deformation of the organ is distinguished separately.

Complications of peptic ulcer

life-threatening complications develop with a peptic ulcer : penetration, perforation (perforation), bleeding and narrowing (stenosis) of the pyloroduodenal part of the stomach.

Ulcers are often complicated by bleeding, even if they did not cause pain. Symptoms of ulcer bleeding may include vomiting bright red blood or a red-brown mass of partially digested blood that resembles coffee grounds, and black, tarry stool. With very intense bleeding, scarlet blood may appear in the stool. Bleeding may be accompanied by weakness, dizziness, and loss of consciousness. The patient must be urgently hospitalized.

Ulcers of the duodenum and stomach can damage the wall of these organs through and through, forming an opening leading into the abdominal cavity. Pain occurs - sudden, intense and constant. It quickly spreads throughout the abdomen. Sometimes a person feels pain, which intensifies with deep breathing. Symptoms are less intense in older people, in people taking corticosteroids or in very seriously ill people. An increase in body temperature indicates the development of an infection in the abdominal cavity. If medical care is not provided, shock (a sharp drop in blood pressure) develops. If the ulcer perforates (perforates), surgery is required.

An ulcer can destroy the entire muscular wall of the stomach or duodenum and invade an adjacent organ, such as the liver or pancreas. This complication is called ulcer penetration .

Swelling of the inflamed tissue around the ulcer or scar from previous exacerbations of the disease can narrow the outlet of the stomach (pyloroduodenal region) or the lumen of the duodenum. With this type of obstruction, repeated vomiting often occurs, and large volumes of food eaten many hours before are released. There is a feeling of fullness in the stomach after eating, bloating and lack of appetite - the most common symptoms of obstruction. Over time, frequent vomiting leads to weight loss, dehydration, and imbalance of minerals in the body. Treatment of the ulcer will relieve the obstruction in most cases, but severe obstruction may require endoscopic or surgical intervention.

Treatment of gastric and duodenal ulcers should only be carried out under the supervision of the attending physician. The fact is that self-administration of various antacids and other drugs that reduce the acidity of gastric juice can alleviate the symptoms of the disease, but this improvement will only be short-term. Only adequate treatment prescribed by a gastroenterologist can lead to complete healing of ulcers.

Main causes

The cause of a defect in the gastric mucosa is considered to be an imbalance between the aggressive secretions of the stomach and the protective qualities of the mucous membrane. To digest food, the stomach secretes pepsin and hydrochloric acid. To prevent them from destroying the stomach, mucus forms on its surface, protecting the organ. If more acid is produced and less mucus is produced, an ulcer may form. The background for such a pathology may be a decrease in gastric motility, a violation of the regenerative - restorative properties of the mucous membrane against the background of certain diseases.

The main etiological cause of ulcer formation is damage to the mucous membrane of the HP. This bacterium successfully survives in an acidic environment and produces an enzyme that causes an inflammatory reaction with subsequent formation of a defect. Helicobacter pylori is detected in 82% of patients suffering from gastric ulcers.

Another reason may be uncontrolled use of anti-inflammatory non-steroidal drugs, such as aspirin.

Provoking factors may be:

• smoking and alcohol abuse;
• constant consumption of spicy food;
• stressful situations;
• hereditary predisposition;
• dry food;
• eating disorder.

Gastric ulcers often develop against the background of certain diseases, such as atrophic gastritis and hormonal pathologies.

Causes of peptic ulcer

One of the main causes of peptic ulcer development is currently considered to be infection caused by the microorganism Helicobacter pylori (H. pylori). However, it should be noted that approximately more than half of the world's population is infected with H. pylori infection, and in many people this infection is asymptomatic; some of those infected develop chronic gastritis, atrophic gastritis, and stomach cancer. The effect of Helicobacter pylori on the gastric mucosa may depend on the state of the host’s immune system; the development of peptic ulcer disease depends on the presence of associated factors.

Factors contributing to the development of peptic ulcer disease (risk factors)

• Neuropsychic factor (stress).
• Smoking (smoking also impairs the healing of ulcers and increases the likelihood of their re-development - relapses; the degree of risk when smoking tobacco depends on the number of cigarettes smoked per day).
• Heredity.
• Violation of the regime and nature of nutrition.
• Alcohol abuse.

For the occurrence of a peptic ulcer, as a rule, it is not the isolated action of one of the listed factors that is necessary, but their combination. From a modern point of view, the development of peptic ulcer disease appears to be the result of an imbalance between the factors of “aggression” and the factors of “protection” of the mucous membrane of the stomach and duodenum. Factors of aggression (acid, gastroduodenal dyskinesia, Helicobacter pylori, etc.) prevail over protective factors (mucoproteins and bicarbonates of mucus, mechanisms for regulating the production of gastric juice, etc.).

Endoscopic stages of peptic ulcer

• open ulcer,
• scarring ulcer,
• stages of red scar, white scar.

Ulcer size

• small (less than 0.5 cm);
• medium (0.5–1 cm);
• large (1.1–3 cm);
• gigantic (more than 3 cm).

Symptoms of the disease

Peptic ulcer usually manifests itself more often in spring and autumn, during the period of exacerbation of the disease. The first sign of the disease is pain that occurs immediately after eating. This is due to the fact that pepsin and hydrochloric acid released during meals aggressively affect the defect unprotected by mucus. Moreover, the manifestations of pain symptoms increase within an hour after eating. The pain is localized in the epigastric region, in the region of the heart, and can radiate - radiate under the scapula, as in a heart attack. At the height of the pain syndrome, nausea often occurs, which can result in vomiting, which brings relief.

Other dyspeptic manifestations and signs of illness: heartburn, loss of appetite, constipation. A coated tongue may indicate stomach problems. Against this background, the patient quickly loses weight.

Clinical picture of peptic ulcer

The most consistent and important symptom of peptic ulcer disease is pain. Pain in peptic ulcer disease has a clearly defined rhythm (time of occurrence and connection with food intake), and seasonality of exacerbations.

Based on the time of occurrence and their connection with food intake, pain is distinguished between early and late, night and “hungry”. Early pain occurs 0.5–1 hour after eating, lasts 1.5–2 hours and decreases as gastric contents are evacuated. Such pain is more typical for gastric ulcer in the upper part.

Late pain appears 1.5–2 hours after eating, night pain occurs at night, and “hungry pain” occurs several hours after eating and stops after eating. Late, night and “hungry” pains are more typical for the localization of an ulcer in the antrum of the stomach or duodenal ulcer.

The nature and intensity of pain may vary (dull, aching, burning, cutting, cramping). The localization of pain in peptic ulcer disease is different and depends on the location of the ulcer: with an ulcer on the lesser curvature of the stomach, pain often occurs in the epigastric region, with duodenal ulcers - in the epigastric region to the right of the midline. With ulcers of the cardial part of the stomach, pain can be behind the sternum or in the heart area; in this case, it is important to differentiate peptic ulcer disease from angina pectoris or myocardial infarction. Pain often occurs after taking antacids, milk, food, and even after vomiting.

In addition to pain, the typical clinical picture of peptic ulcer disease includes various dyspeptic symptoms.

Heartburn is one of the early and frequent symptoms characteristic of peptic ulcer disease. Heartburn can occur at the same time after eating as pain. It often precedes the onset of pain, and subsequently is often combined with pain. These two symptoms are closely related, and some patients have difficulty distinguishing between them. In later stages of the disease, heartburn may disappear. But sometimes it can be the only subjective manifestation of a peptic ulcer.

Belching is a fairly common, but not specific symptom of peptic ulcer disease. The most typical belching is sour. The appearance of belching is associated with impaired evacuation of gastric contents due to prolonged spasm and severe inflammatory edema of the pylorus or duodenal bulb. It should also be remembered that belching is characteristic of a diaphragmatic hernia.

Nausea and vomiting are dyspeptic symptoms characteristic of exacerbation of peptic ulcer disease. Nausea is often accompanied by vomiting, although vomiting can occur without preceding nausea.

Vomiting in patients with peptic ulcer disease often has some specific features: firstly, it occurs at the height of pain, being, as it were, the culmination of pain; secondly, it brings significant relief. Vomit, as a rule, has an acidic reaction with an admixture of recently eaten food. Vomiting can also occur on an empty stomach.

Appetite in case of peptic ulcer is usually preserved or even increased (the so-called painful feeling of hunger). Decreased appetite is possible with severe pain syndrome; fear of eating may occur due to the possibility of pain occurring or increasing. Decreased appetite and fear of food can lead to significant weight loss for the patient.

Constipation is observed in half of patients with peptic ulcer disease, especially during exacerbation. Constipation in peptic ulcer disease is caused by a number of reasons: spastic contraction of the colon, a gentle diet, poor coarse fiber and the resulting lack of intestinal stimulation, limitation of physical activity, and the use of antacids (Almagel, etc.).

Symptoms depend on the location of the ulcer and the age of the patient . In some cases there may be no pain (painless ulcers). In these cases, ulcers are discovered when complications develop (ulcer bleeding, ulcer perforation - breakthrough of the ulcer wall into the abdominal cavity, penetration of the ulcer). Only about half of people with duodenal ulcers (duodenal ulcers) have typical symptoms. In children, the elderly, and patients taking certain medications, symptoms may be atypical or absent altogether.

Treatment of the disease

Gastric ulcers are well treated with conservative methods, which include pharmacotherapy and physiotherapeutic procedures. In emergency and some other cases, surgical intervention is indicated.

Drug treatment

The treatment of gastric ulcers uses complex pharmacotherapy, including medications aimed at the root cause of the pathology, relieving irritation of the mucous membrane and creating a protective barrier for gastric juice and relieving pain. The main group of drugs includes:

1. Proton pump inhibitors are long-acting drugs that reduce gastric secretory activity.
2. Antacids - envelop the mucous membrane, protecting it from the aggressive effects of gastric juice, and reduce its acidity.
3. Antibacterial drugs are aimed at eradication (destruction) of Helicobacter pylori. The best effect is achieved when antibiotics are combined. For peptic ulcers, macrolides, antiprotozoal drugs, penicillin and tetracycline antibiotics are prescribed.
4. Bismuth preparations relieve inflammation and form an insoluble colloid that creates a protective film when combined with protein.
5. Vitamin B5 (Pantothenate) - normalizes the production of hydrochloric acid, stimulates the regeneration of the mucous membrane.
6. Methylmethionine sulfonium chloride, also called vitamin U, acts as a cytoprotector that helps reduce gastric secretion and heal gastric ulcers.

Treatment can be supplemented with other drugs aimed at eliminating the causes of ulcerative pathology.

Physiotherapy

Physiotherapy helps ulcer healing and can be used in complex therapy. The mechanisms of self-regulation and adaptation are beneficially affected by:

• laser puncture - exposure of bioactive points with a laser beam;
• EHF therapy - the influence of electromagnetic waves in the millimeter range;
• magnetotherapy - exposure to low-frequency magnetic fields.

Ultrasound therapy is used to improve gastric motility in case of gastric atony. This procedure also improves blood supply to the organ, reduces the number of bacteria and relieves inflammation.

Surgery

Emergency surgery is performed in case of massive bleeding and perforated gastric ulcer. Surgical intervention is also indicated for complicated forms of ulcers in the case of a non-healing ulcer, as well as for malignancy, when the pathology becomes malignant. In some cases, gentle methods are used: laparoscopy or endoscopy.

Diagnosis of peptic ulcer

The doctor may suspect the presence of ulcers in the stomach or duodenum if the patient has characteristic complaints. After examining and questioning the patient, the doctor will prescribe a series of studies to confirm or exclude the diagnosis of peptic ulcer.

Endoscopic examination of the stomach and duodenum - FEGDS (fibroesophagogastroduodenoscopy). In this study, the doctor inserts a thin, flexible instrument (fiber optic tube - endoscope) with a light source and a micro-camera at the end into the esophagus and further into the stomach and duodenum (12 pcs) of the patient.

The study is carried out to examine the internal surface of the gastrointestinal tract (to detect ulcers and determine their location, as well as to exclude complications: bleeding, perforation, penetration, stenosis). During the study, the doctor can take tissue samples (biopsies) from the stomach.

The obtained biopsies are examined in laboratory conditions to exclude a malignant disease (for gastric ulcers), detect Helciobacter pylori, and clarify the type of gastritis. An endoscope can also often be used to stop bleeding from an ulcer (cauterization of the ulcer).

X-ray examination . An overview image of the abdominal organs is performed if there is a suspicion of ulcer perforation (perforation of the wall of the stomach or duodenum), while an accumulation of free gas (air) coming from the gastrointestinal tract is determined in the abdominal cavity.

If a tumor, pyloric stenosis or 12 PC is suspected, an X-ray examination of the stomach and duodenum is performed after taking a barium suspension.

Tests to detect H. pylori infection. Currently, there are many methods for diagnosing H. pylori infection, including a urease breath test, determination of antibodies in the blood, PCR diagnostics for the presence of H. pylori in stool, and biopsy of the gastric mucosa for the presence of H. pylori.

Blood test . A complete blood count will not detect an ulcer, but may reveal anemia resulting from ulcer bleeding or an elevated white blood cell count as a sign of complications.

Diet and bad habits for stomach ulcers

Diet for gastrointestinal ulcers is an essential part of treatment. During the acute period, nutrition should be as gentle as possible, gentle on the mucous membrane and not stimulating the secretory activity of the stomach. In the first two days, preference is given to slimy soups with rice water without vegetables and meat, jelly or warm tea with sugar and crackers. In the next 6 days, table No. 1 is used in therapeutic nutrition.

Authorized Products

General nutrition rules:

• include easily digestible foods in the diet;
• food should be warm
• Do not eat cold or hot foods;
• you need to eat slowly, in small portions
• products need to be crushed and ground;
• Baking, boiling, stewing is allowed;
• fried foods and spices are excluded;
• the break in eating should not be more than 3 hours;
• food must be chewed thoroughly.

The following foods and dishes are allowed for stomach ulcers:

1. Slimy soups: with the addition of rice, semolina, oatmeal, you can add cream or butter;
2. Slimy porridges: with water or milk from the same cereal, you can add cream;
3. Fish and meat: lean beef, veal, turkey, rabbit, chicken. To prepare the meat, you need to boil it, pass it through a meat grinder, add butter, bake it into a soufflé puree, you can cook steamed cutlets, meatballs, meatballs;
4. Eggs: soft-boiled, or steam omelet;
5. Berries and fruits: baked unsweetened fruits, dried fruit compotes;
6. Dairy products: milk, steamed pureed cottage cheese soufflé, cream.
7. Drinks: weak tea with added cream or milk, rosehip decoction, milk or fruit jelly.

You can add refined vegetable oil or unsalted butter to dishes.

Prohibited Products

During an exacerbation, foods that irritate the gastric mucosa and increase the production of gastric juice are excluded: fatty meat, baked goods, preserves, canned and smoked foods, confectionery with cream, dishes with vinegar and spices, garlic.

Do not include vegetables with coarse fiber in the diet, as well as radishes, radishes, daikon, cabbage, tomatoes, turnips, and mushrooms.

It is necessary to avoid foods that cause fermentation processes: legumes, sweet fruits and juices, carbonated drinks.

During the treatment period, you are strictly prohibited from smoking and drinking alcohol.

Prevention of peptic ulcers

Stomach ulcers can be avoided if you follow some rules. First of all, give up bad habits, since ethyl alcohol and tobacco reduce the protective properties of the mucous membrane and irritate it.

Diet is no less important in prevention: you need to eat at a certain time, the interval between meals should not exceed 4 hours. You cannot eat dry food, as dry rough food injures the walls of the stomach.

For those who work at night, it is recommended to change jobs to work only during the daytime. It is necessary to avoid stress, treat inflammation of the stomach, hormonal diseases, and visit a gastroenterologist at least once every six months.
