What causes belly button and abdominal pain?

Many people usually experience abdominal distension and pain, and distension and pain around the navel. This is caused by the abdominal organs. It is not ruled out that it is caused by organ damage in the abdominal cavity, acute gastrointestinal inflammation, acute corrosive gastritis, and cholecystitis. Patients will experience diarrhea, abdominal distension, and severe cases will be accompanied by abdominal cramps. It is necessary to go to the hospital for blood, urine, and stool tests to confirm the cause. Other treatments are very important.

Pathological etiology

1. Causes of acute abdominal pain

(1) Diseases of abdominal organs:

① Acute inflammation of abdominal organs: acute gastroenteritis, acute corrosive gastritis, acute cholecystitis, acute pancreatitis, acute appendicitis, acute cholangitis, etc.

② Perforation or rupture of abdominal organs: perforation of gastric and duodenal ulcers, perforation of typhoid intestinal organs, rupture of liver, rupture of spleen, rupture of kidney, rupture of ectopic pregnancy, rupture of ovary, etc.

③ Obstruction or expansion of abdominal organs: gastric mucosal prolapse, acute intestinal obstruction, inguinal hernia, intussusception, biliary ascariasis, cholelithiasis, kidney and ureteral stones, etc.

④ Torsion of abdominal organs: acute gastric torsion, ovarian cyst torsion, omentum torsion, intestinal torsion, etc.

⑤ Intra-abdominal vascular obstruction: acute obstruction of the mesenteric artery, acute portal vein thrombosis, dissecting abdominal aortic aneurysm, etc.

(2) Abdominal wall diseases: abdominal wall contusion, abdominal wall abscess and abdominal wall herpes zoster, etc.

Inspection method

Laboratory tests:

1. Routine blood, urine, stool tests, ketone bodies and serum amylase are the most commonly used laboratory tests.

2. Diagnostic puncture can be performed for peritonitis, internal bleeding, abdominal abscess and certain abdominal masses, and routine smear, bacterial culture or pathological examination can be performed on the punctured material.

Other auxiliary examinations:

1. X-ray examination: When the diagnosis is difficult and there is a suspicion of chest and abdominal lesions, chest and abdominal fluoroscopy can be performed to observe whether there are lesions in the chest, whether there is free gas under the diaphragm, changes in diaphragm movement, intestinal gas and fluid level, etc. If any abnormality is found, routine X-rays should be taken. When sigmoid colon volvulus or low intussusception is suspected, barium enema examination can be performed; barium meal examination is not suitable for patients suspected of intestinal obstruction, fistula or perforation.

2. Ultrasound examination is mainly used to examine bile duct and urinary system stones, bile duct dilatation, pancreatic and hepatosplenomegaly, etc. It also has good diagnostic value for small amounts of abdominal effusion, intra-abdominal cysts and inflammatory tumors.

3. Endoscopic examination Endoscopic examination has become an important means to find the cause of abdominal pain. If the patient's condition permits, retrograde pancreaticocholangiopancreatography, cystoscopy and laparoscopy can also be performed.

4. CT, MRI and radionuclide scanning examinations have good diagnostic value for intra-abdominal and retroperitoneal lesions, such as lesions of the liver, spleen, pancreas, some intra-abdominal tumors, and abdominal abscesses, effusions, and gas accumulation. They should be selected and used reasonably according to the condition of the disease.

5. Electrocardiogram examination: For older people, an electrocardiogram should be performed to understand the myocardial blood supply and rule out myocardial infarction and angina pectoris.
