Sudden left abdominal pain in a child

Parents are more concerned about their children's physical movements. When a child suddenly experiences pain in the left side of the abdomen, it is important to observe the cause. It is not ruled out that it is caused by gastrointestinal inflammation and appendicitis. Therefore, it is very important for patients to go to the hospital for relevant examinations based on their personal physical conditions.

(1) Pediatric diseases,

1. Intra-abdominal diseases: acute gastritis, gastroenteritis, gastric and duodenal ulcers, intestinal spasmodic colic, intestinal and biliary ascariasis, mesenteric lymphadenitis, acute necrotizing enteritis, viral hepatitis, congenital common bile duct cyst, various pancreatitis, various peritonitis, liver abscess, subphrenic abscess, urinary tract infection, bacterial dysentery, etc.

2. Extra-abdominal diseases: respiratory diseases (upper respiratory tract infection, tonsillitis, lobar pneumonia, acute pleurisy), cardiovascular diseases (acute heart failure, pericarditis, myocarditis), allergic diseases (allergic purpura, urticaria, asthma), nervous system diseases (intercostal neuralgia, abdominal epilepsy), metabolic diseases (hypoglycemia, uremia, porphyria), infectious diseases (typhoid fever, epidemic cerebrospinal meningitis) and sepsis, herpes zoster, lead poisoning, etc.

Acute appendicitis, gastric and duodenal ulcers with perforation, mechanical intestinal obstruction, intussusception, mesenteric artery embolism, acute intestinal torsion, ileal diverticulitis with perforation, obstruction, primary or secondary peritonitis, incarcerated inguinal hernia, urinary tract stones, hydronephrosis, liver rupture, spleen rupture, ovarian cyst torsion, testicular pedicle torsion, iliac fossa abscess, etc.

Disease diagnosis

It is mainly necessary to differentiate it from some diseases that cause abdominal pain, such as obstructive diseases, spasm of hollow organs such as the stomach, intestines, and bile duct, gastrointestinal perforation, peptic ulcer, etc.

1. Laboratory examination: Routine examination of blood, urine and stool can sometimes provide information of diagnostic value. For example, if hemoglobin and red blood cells gradually decrease, one must be alert to the presence of internal bleeding. An increase in the total white blood cell count often indicates inflammatory lesions. Observation of the nature of stool is helpful for the diagnosis of intestinal infection and intussusception. A large number of red blood cells or pus cells in the urine indicates urinary tract infection. If necessary, blood and urine pancreatic amylase should be tested.

2. X-ray examination: Chest X-ray examination can show lung, pleural and heart lesions. Abdominal fluoroscopy and radiography examinations, such as the discovery of free gas under the diaphragm, indicate gastrointestinal perforation; trapezoidal liquid planes in the intestines and a lot of air in the intestinal cavity indicate intestinal obstruction. If intussusception is suspected, air enema can be performed to assist in diagnosis and repositioning treatment, but it is contraindicated for those suspected of visceral perforation. Abdominal plain films or intravenous pyelography can be performed if urinary tract lesions are suspected.

3. B-mode ultrasound: Perform abdominal B-mode ultrasound examination when cholelithiasis, liver abscess, or subphrenic abscess is suspected.
