appendix cavity occlusion
Introduction
Introduction The occlusion of the appendix cavity is often caused by dung stones, dry junk blocks, food debris, foreign bodies, mites, and the like. It can lead to infection and suppuration of the appendix. Clinical manifestations of high fever and abdominal pain. Because the complication of the disease is serious, it is inconvenient for normal life and work, and the quality of life is lowered. Therefore, it should be actively treated. First, it is necessary to actively control the primary disease such as tsutsugamushi. Usually pay attention to diet hygiene and moderate exercise to prevent constipation, while improving the body's immunity and preventing disease.
Cause
Cause
The main causes of appendix obstruction are:
(1) In the tail cavity, such as feces, small fruit nucleus, aphids and the like.
(2) stenosis of the appendix wall: If you have had acute appendicitis before, after curing with the drug, the wall of the appendix will make the wall of the appendix smaller. At the same time, it can also weaken the peristaltic function of the appendix.
(3) Lymphatic tissue on the wall of the appendix, and appendix tumors can also cause obstruction.
(4) There is abundant lymphoid tissue on the wall of the appendix, and the inflammatory reaction is serious, which further promotes the occurrence of obstruction.
Examine
an examination
The tenderness and rebound tenderness of the McPherson point (McBurney point) is an important sign of clinical acute appendicitis. The Mews point, the surface projection of the root of the appendix, is usually marked by the intersection of the middle and outer 1/3 of the umbilical cord and the right anterior superior iliac spine. Sometimes it is also indicated by the middle and right 1/3 intersections (Lanz points) of the left and right iliac anterior superior iliac spine lines. McBurney points and Lanz points. In addition, blood tests, urine routines, ultrasound examinations, etc. can also be diagnosed.
Diagnosis
Differential diagnosis
Obstruction: The appendix is a slender tube. Only one end is connected to the cecum. Once obstructed, the endocrine secretions can be accumulated, the internal pressure is increased, and the appendix wall is pressed to block the distal blood supply. On this basis, the bacterial invasion in the lumen is affected. Damage to the mucous membrane, easy to cause infection. Common causes of obstruction are: 1 clogging the fecal stone in the appendix cavity, dry junk, food debris, foreign bodies, mites, etc.
2 The wall of the appendix was destroyed and the lumen was narrow or stuck.
3 The appendix formed by the shortness of the appendix is too short, which hinders the smooth flow of the tube.
4 The lymphatic tissue hyperplasia or edema in the wall of the appendix causes the lumen to become narrow.
5 The appendix opens in the vicinity of the cecal area, such as inflammation, polyps, tuberculosis, tumors, etc., so that the appendix opening is compressed and the emptying is blocked. Among them, fecal stone obstruction is the most common, accounting for about 1/3.
Obstruction is a common basic factor in the pathogenesis of acute appendicitis. Therefore, in the early stage of acute appendicitis, there are often xiphoid or umbilical colic, which is caused by obstruction of the appendix lumen and increased internal pressure. In addition, the specimen of the appendix is often seen in the specimen of the fecal stone obstruction, and the distal end is obviously inflammatory or even gangrenous.
