Identify the truth behind summer abdominal pain

Identify the truth behind summer abdominal pain

The summer climate is hot, the food is easy to spoil, and poor diet hygiene can easily cause insulin infection, leading to abdominal pain and diarrhea, especially pus and blood.

In this case, people first think of bacterial dysentery (hereinafter referred to as bacillary dysentery).

Because bacillary dysentery is a common gastrointestinal infectious disease in summer, the pathogenic system of dysentery bacillus is infected orally through food contamination.

Once suffering from the germs, patients will develop cold, fever, abdominal pain, diarrhea, mucus, pus and blood, and acute inhalation symptoms. Most patients have symptoms, combined with laboratory tests such as blood routine, stool routine or bacterial culture.Clear diagnosis is not difficult.

However, the symptoms of abdominal pain, diarrhea, and purulent stool that occur in summer cannot be identified simply as the performance of bacillary dysentery, and the differential diagnosis must be carefully done, that is, to identify the following diseases that also have abdominal pain, diarrhea, and purulent stool, so as not to causeMisdiagnosis or missed diagnosis.


Amoebic dysentery: It is a disease caused by amoebic protozoa, which is relatively rare.

The clinical features are slow onset, no fever or low fever.

Symptoms of abdominal pain and diarrhea occurred in different degrees, but there was no pus and bloody stools, but jam-like stools were present, and the amount of feces was large, and he was severe after anxiety.

Microscopic examination showed amoebas.


Campylobacter jejuni infection: is an acute acute infectious disease caused by Campylobacter jejuni.

Clinically, the onset is relatively rapid, moderate fever, acute abdominal pain, diarrhea, and bloody stools. It can also be accompanied by acute exacerbations and is easily misdiagnosed as bacteremia. There are three main points of identification: First, children and the elderly are the main targets of disease. AdultsPeople are rare; second, neutrophils and red blood cells are mixed in feces; third, Campylobacter can be seen in bacterial culture under anaerobic environment.


E. coli enteritis: Pathogenic E. coli enteritis occurs in children. After the illness, fever, abdominal pain, diarrhea, and mucus will need to be identified.

The identification points mainly include: (1) Most occur in May-August.

  (2) The onset is relatively slow, starting with mild, no fever, rarely vomiting, and gradually developing into severe.

  (3) The stool is like egg soup, smelly, and has mucus.

  (4) Fecal drops, mucus, and a small amount of cells were found on the stool.


Bacterial food poisoning: mostly caused by Salmonella and halophiles, occasionally caused by Staphylococcus aureus.

The clinical feature is that many people who have eaten together have developed the disease and have similar performances. This is the main basis for distinguishing bacterial food poisoning from bacillary dysentery.

Once food poisoning occurs, abdominal pain, diarrhea, or bloody stools and mucus stools, but in a few cases are yellow stools or watery stools, usually without urgency, and then heavy, and nausea, vomiting, and vomiting can precede abdominal pain, diarrhea, orOccurring at the same time, this is another point of identification with the bacterium.


Acute hemorrhagic and necrotic enteritis: This is an infectious disease with acute onset and severe symptoms of poisoning. It is usually caused by Bacillus gassing infection. Abdominal pain, diarrhea, blood in the stool, and fever are the main symptoms of the disease.Identification with bacteria.
Abdominal pain in acute hemorrhagic necrotizing enteritis is mostly persistent faint pain or paroxysmal colic, and the paroxysmal aggravation.

May have abdominal tenderness points but more diffuse, severe cases of bleeding peritoneal irritation.

The stool smelly is pasty, dark red or bright red, with a large amount each time, but no mucus, no pus, and heavy after anxiety, so it is one of the main characteristics.


Intussusception: It is more common in infants and young children. It is caused by a section of intestinal canal being inserted into its adjacent or proximal intestinal cavity, which causes the intestinal wall of this section to overlap and congest the intestinal cavity.

Intussusception is clinically characterized by abdominal pain, vomiting, and dark red stools or bloody stools that need to be distinguished from bacillary dysentery.

The identification points include: (1) paroxysmal abdominal pain, which is replaced at the beginning, and can be subsequently relieved; (2) the examination has abdominal masses, which are mostly located in the right upper abdomen or the middle of the abdomen, and the surface is smooth and slightly movable;The block is more obvious, accompanied by hyperintestinal sounds; (3) X-ray examination of barium enema can assist diagnosis.
