Gastric mucosal prolapse

Introduction to gastric mucosal prolapse Prolapse of gastric mucosa is caused by the abnormally loose gastric mucosa retrograde into the esophagus or forward into the duodenal bulb through the pyloric duct. It is more common in the clinic. basic knowledge The proportion of illness: 0.02% Susceptible people: no specific population Mode of infection: non-infectious Complications: bloating, pyloric obstruction

Causes of gastric mucosal prolapse

The occurrence of this disease is mainly related to inflammation of the gastric antrum. The malignant cell infiltration of the gastric mucosa can also occur. When the gastric antrum is inflamed, the submucosal connective tissue is loose, and the gastric mucosa and submucosa proliferate, such as gastric antrum peristalsis. Mucosal folds are easily sent to the pylorus, forming gastric mucosal prolapse, all factors that can cause severe gastric peristalsis, such as mental stress, tobacco and alcohol, coffee stimulation, etc. are the cause of the disease, the disease often with the stomach and twelve Intestinal inflammation coexists, and the relationship between them needs further study.

Prevention of gastric mucosal prolapse

Mainly take a small meal and more meals, left lateral position, while using sedatives and anticholinergic drugs and other measures.

Gastric mucosal prolapse complications Complications, abdominal distension, pyloric obstruction

Often combined with duodenal ulcer, often accompanied by symptoms of dyspepsia such as hernia, pantothenic acid, abdominal distension, and sometimes sudden symptoms of pyloric obstruction, but disappeared more quickly.

Symptoms of gastric mucosa prolapse Symptoms Abdominal distension peptic ulcer abdominal pain gastric mucosal prolapse nausea abdominal tenderness hernia

This disease is more common in men aged 30 to 60 years old. Mild patients can be asymptomatic, or only non-specific symptoms such as abdominal distension and hernia. Some gastric mucosa can be removed into the pylorus and cannot be immediately reset. There may be pain in the upper abdomen, burning pain and even Colic, and can be radiated to the back, often accompanied by nausea, vomiting, the appearance of symptoms often associated with the patient's body position, such as the right lateral position is prone to occur, the left lateral position is less, or even does not occur, due to eating Promoting the peristalsis of the stomach is conducive to the occurrence of gastric mucosal prolapse, so the symptoms are often related to eating, but lack of obvious periodicity and rhythm. The use of alkaline drugs can also relieve pain, but the effect is far worse. Peptic ulcer is significant, upper abdominal tenderness may be the only positive sign of this disease, when the prolapsed mucous membrane obstructs the pyloric tube and incarcerates or strangles, the upper abdomen can reach a soft and tender mass, and pyloric obstruction Symptoms, with or without gastrointestinal bleeding.

Examination of gastric mucosal prolapse

Some patients have positive fecal occult blood test. During gastroscopy, the mucosa of the antrum is normal, or congestion, edema; sometimes bleeding spots, erosion or superficial ulcers; when the gastric antrum contracts, the gastric mucosa enters with the pylorus through the pylorus. In the duodenum, when diastolic, the prolapsed gastric antrum mucosa can be restored from the pylorus to the gastric cavity. X-ray gastrointestinal barium meal examination has a certain diagnostic value. When the patient takes the prone position and the right lateral position, the variable ten can be seen. The central part of the duodenal bulb is filled with a central filling defect. In a typical case, the pyloric tube is widened. The gastric mucosal folds enter the duodenal bulb through the pyloric tube, causing the duodenal bulb to be "sick" or "parachute". .

Diagnosis and differentiation of gastric mucosal prolapse

The disease lacks characteristic symptoms and signs in the clinic. The value of endoscopy is limited. The diagnosis depends mainly on X-ray barium meal examination. The disease needs to be differentiated from peptic ulcer and chronic gastritis. The former has periodic pain, rhythm, pain and Irrespective of position, X-ray barium meal examination can be seen in the shadow, the latter gastroscopy is helpful for diagnosis.

The disease should be differentiated from pyloric tube, pyloric muscle hypertrophy and gastric cancer.
