posterior pharyngeal diverticulum
Introduction
Introduction to the posterior pharyngeal wall More common, the capsular-like tissue formed by the mucosa and submucosa between the pharyngeal muscle and the pharyngeal muscle of the hypopharyngeal pharyngeal muscle. More common in middle-aged men. In the early stage of the disease, there may be symptoms such as pharyngeal foreign body sensation, obstruction, food reflux, etc. The retention of indoor food may cause bad breath, smell when breathing, pain may occur when the mucous membrane is inflamed, solid food is more difficult to swallow than fluid, diverticulum Compressed trachea can cause irritating cough or hoarseness. The body can be seen to be full of the lower part of the posterior triangle. When the pressure is pressed, gas or liquid overflows from the mouth, sometimes with a sound, and the mass shrinks. Small and asymptomatic patients with diverticulum may not be treated for the time being, and those with obvious symptoms may be treated with external cervical surgery or endoscopic surgery. Endoscopic surgery was performed under esophagoscopy. The anterior lip was inserted into the esophagus and the posterior lip was inserted into the diverticulum. The wall of the diverticulum was horizontally tweeted. The wall was cut with scissors. The electrocoagulation stopped bleeding and the opening of the diverticulum was enlarged. The esophagus is connected, and the food does not remain in the chamber and enters the esophagus. basic knowledge The proportion of sickness: 0.0023% Susceptible people: more common in middle-aged men Mode of infection: non-infectious Complications: bad breath, difficulty swallowing
Cause
Cause of pharyngeal wall diverticulum
Stress factor (85%):
The reason for the posterior pharyngeal wall diverticulum is that the pharyngeal wall is weak and the pressure in the pharyngeal cavity is increased. The hypopharyngeal muscles are easily separated between the pharyngeal muscle and the pharyngeal muscle, and the lower edge of the pharyngeal muscle is tightly attached to the upper edge of the esophagus. For example, the weakness of the pharyngeal muscle can cause different degrees of pharyngeal cavity enlargement. When the pressure in the laryngopharyngeal is increased, the muscle fibers between the inferior pharyngeal wall and the pharyngeal muscle are separated, and the mucosa and submucosa protrude outward. Apparent pockets gradually formed later.
Disease factors (15%):
Patients with muscle weakness.
Prevention
Ventral wall diverticulum prevention
The reason for the posterior pharyngeal wall diverticulum is that the pharyngeal wall is weak and the pressure in the pharyngeal cavity is increased. The hypopharyngeal muscles are easily separated between the pharyngeal muscle and the pharyngeal muscle, and the lower edge of the pharyngeal muscle is tightly attached to the upper edge of the esophagus. . If the nail muscles are weak, it can cause different degrees of pharyngeal enlargement. The development of the inferior pharyngeal muscle is usually congenital, and can be performed by blowing, such as blowing a balloon, and the latter singing can promote the development of the pharyngeal muscle to reduce the prevalence of the disease.
Complication
Posterior pharyngeal diverticulum complications Complications, bad breath, dysphagia
Insufficient indoor food can cause bad breath, smell when breathing, pain can be caused when there is inflammation in the mucous membrane, solid food is more difficult to swallow than fluid, and diverticulum can cause irritating cough or hoarseness.
Symptom
Posterior pharyngeal wall diverticulum symptoms common symptoms bad breath dysphagia
According to the clinical manifestations can be diagnosed, X-ray barium meal perspective, visible tincture filled with diverticulum or gas inside; esophagoscopy can be seen in the posterior pharyngeal wall at the midline of the diverticulum opening and accumulation of spillage.
In the early stage, there may be symptoms such as pharyngeal foreign body sensation, obstruction, food reflux, etc. The presence of indoor food may cause bad breath, smell when breathing, pain may occur when the mucous membrane is inflamed, solid food is more difficult to swallow than fluid, and diverticulum is compressed. Irritating cough or hoarseness may occur. The lower part of the posterior triangle of the neck may be full. When there is pressure, gas or liquid overflows from the mouth, sometimes with a sound, and the mass shrinks.
Examine
Examination of the posterior pharyngeal wall
X-ray barium meal perspective, it can be seen that the tincture is filled with diverticulum or gas inside it; esophagoscopy can be seen in the midline of the posterior pharyngeal wall with diverticulum opening and accumulation of spillage.
Diagnosis
Diagnostic diagnosis of posterior pharyngeal wall
It can be diagnosed according to clinical manifestations without identification.
