Parasitosis of the appendix

Introduction to Iris Parasitic Diseases Acute appendicitis caused by appendicitis is a common surgical acute abdomen, and many intestinal parasites can parasitize or enter the appendix cavity. For example, schistosomiasis appendicitis is common in the endemic areas of schistosomiasis in southern China. Iris tsutsugamushi is common in the northern region and is one of the complications of intestinal ascariasis. Amoebic bowel disease occurs in the cecum, and there are more chances involved in the appendix. basic knowledge The proportion of illness: 0.003%--0.005% Susceptible people: no specific population Mode of infection: digestive tract spread Complications: acute peritonitis

The etiology of appendicitis

1. Chronic inflammatory process of schistosomiasis appendicitis, leukocyte infiltration, small mucosal ulcer formation, gradual fibrosis, granuloma formation or mucosal scar stenosis after long-term stimulation, and severe perivascular lesions can also cause poor blood supply to the appendix. Changes can be the pathological basis for the onset of acute appendicitis.

2. Iris tsutsugamushi mites usually parasitize in the human ileum, such as diarrhea, deworming, pregnancy, etc., causing abnormal bowel movements, changes in the intestinal environment, and the mites have boreholes, so they can enter the cecum and drill the appendix to develop appendix mites. Disease, aphids can cause obstruction of the appendix cavity after entering the appendix cavity. Aphid peristalsis stimulates the muscle spasm of the appendix wall, which can cause acute appendicitis.

3. Chronic amoebic appendicitis due to amoebic bowel disease occurs in the cecum, so there is more chance of involving the appendix. In the autopsy of colonic amoebia, it is found that 4.0% to 6.2% have amoebic appendicitis, and some form Abscess or perforation, simple amoebic appendicitis is rare.

Iris parasitic disease prevention

1. Pay attention to food hygiene, do not eat unclean cold food, raw vegetables and fruits must be washed before eating.

2. Develop good hygiene habits, not to stool anywhere. The transmission route of tsutsugamushi disease is that the eggs excreted by mites are excreted with the stool, which in turn pollutes the surrounding environment, and can contaminate vegetables, fruits and fruits. Once swallowed, they can be infected. To wash your hands before and after meals, cut your nails, children should not suck your fingers.

3. In the prevention and control of tsutsugamushi disease, it is necessary to carry out publicity and education on health and cultivate good hygiene habits. The focus of the census is on children's collective units (kindergarten, primary school), census and general rule to protect children's health, strengthen manure management and improve the environment. Hygiene, do fly control, fly prevention work to prevent the spread of eggs, experiments prove that eggs die within half an hour at 45--50 ° C, building a septic fermented septic tank or using composting methods - that is, using the heat generated by fermentation And the action of ammonia decomposed from the excrement of urine, killing eggs in the feces.

Iris parasitic complications Complications acute peritonitis

Secondary infection produces acute appendicitis, which is the inflammatory phase. Following the increase in pressure in the appendix, ischemia, necrosis, and perforation of the appendix wall, aphids can be drilled into the abdominal cavity, causing severe suppurative peritonitis.

Acute appendicitis caused by appendicitis is a common surgical acute abdomen, and many intestinal parasites can parasitize or enter the appendix cavity. For example, schistosomiasis appendicitis is common in the endemic areas of schistosomiasis in southern China. Iris tsutsugamushi is common in the northern region and is one of the complications of intestinal ascariasis. Amoebic bowel disease occurs in the cecum, and there are more chances involved in the appendix.

Schistosomiasis appendicitis

The symptoms of schistosomiasis appendicitis are the same as those of general acute appendicitis, but the disease block, perforation rate is high, and there are many residual abscesses and intestinal fistula after surgery. These characteristics should cause clinical attention.

2. Iris tsutsugamushi

Abdominal pain is often paroxysmal cramps in the umbilical cord, which is far more severe than general appendicitis abdominal pain. Metastatic right lower abdominal pain occurs quickly, and fixation is also fast. Intermittent colic is often intermittent. Obstruction period, obstruction is not relieved, appendix injury, secondary infection produces acute appendicitis that is inflammatory, followed by increased pressure in the appendix, ischemic, necrotic, perforation of the appendix wall, aphid can drill into the abdominal cavity, causing severe suppurative peritonitis.

3. Chronic amoebic appendicitis

Repeated episodes of right lower quadrant tenderness, or persistent discomfort in the armpits, may have an acute attack when accompanied by suppurative infection. The symptoms of this disease are similar to bacterial appendicitis, which is often found during surgery. The lesion is not limited to the appendix, the cecum. The wall also showed thickened edema.

Examination of appendicial parasitic diseases

X-ray sputum of the appendix tsutsugamushi can be found in the signs of the appendix, and the colonoscopy can confirm the diagnosis and take the insects.

Diagnosis and identification of iris parasitic diseases

diagnosis

Can be diagnosed based on clinical symptoms and laboratory tests.

Differential diagnosis

It is differentiated from general acute appendicitis.
