Usually patients with abdominal pain are recommended to do physical examination, laboratory tests, imaging tests, etc. 1. Physical examination: check whether the patient has hyperactive bowel sounds through auscultation. By palpation, it is clear whether the patient has total abdominal pain or localized pain, whether the liver and spleen are enlarged, and whether there is local pressure, rebound pain and abdominal mass. 2. Laboratory tests: blood, urine, fecal routine can check the total number of blood leukocytes and neutrophils increase suggesting inflammatory lesions. If there are a lot of red blood cells in the urine, it suggests urinary stones, tumors or trauma; proteinuria and leukocytes suggest urinary tract infection; pus and blood stools can also suggest intestinal infection or intestinal inflammatory lesions. 3. Imaging examination: real-time ultrasound and CT examination can be chosen, which plays an important role in the differential diagnosis of liver, gallbladder and pancreatic diseases; if necessary, liver puncture + pathological biopsy according to the positioning of ultrasound examination can confirm the diagnosis of liver abscess and hepatocellular carcinoma, etc. X-ray gastrointestinal barium contrast or gastrointestinal microscopy can find gastrointestinal ulcers, tumors and other diseases. In addition, it is recommended that patients with abdominal pain go to the hospital in time, do relevant examinations, clarify the cause of the disease and then follow the doctor’s instructions for treatment, so as to avoid delaying the condition.
