The stomach is especially hard and painful when pressed, which may be caused by acute diffuse peritonitis, intussusception, pyloric obstruction, etc. The patient needs to follow the doctor’s instructions for medication and surgical treatment. Acute diffuse peritonitis: usually patients need to fast in time, take a semi-recumbent position, and also need to correct the water electrolyte disorders. Some patients also need to supplement calories or nutritional support, and use antibiotics such as cefuroxime under the guidance of the doctor for treatment. If non-surgical treatment is ineffective, surgical treatment such as resection of the lesion, repair of the perforation, abdominal drainage, etc., should be chosen according to the doctor’s instructions. Intussusception: Usually, early patients can be reset by enema, and the main ways are water pressure enema therapy under ultrasound monitoring, air pressure enema method, barium enema water pressure reset method. If the patient’s condition is more serious, it is necessary to choose to carry out intussusception reset surgery, intestinal resection anastomosis, enterostomy and so on under the guidance of the doctor. 3. Pyloric obstruction: patients can follow the doctor’s instructions to use rabeprazole, omeprazole and other acid-suppressing drugs, and also need to be used in conjunction with amoxicillin, cephradine and other antibiotic therapy. If the patient’s non-surgical treatment is ineffective or the condition is serious, then you can also choose to carry out gastrojejunostomy, vagotomy, gastric resection, highly selective vagotomy, and so on. It is recommended that when the patient has the symptom of stomach hardness and pain when pressed, the cause of the disease should be clarified in time and targeted treatment should be taken.
