Symptoms of pyloric obstruction? Let's talk about it

Symptoms of pyloric obstruction

General patients have a long history of ulcer, with the progress of lesions, stomach pain gradually aggravated, and belching, nausea and other symptoms. Patients are often anorexic due to gastric distension, and antacids are gradually ineffective. The stomach expanded gradually, the upper abdomen was full, and there were mobile masses.

matters needing attention

In general, emergency operation is not suitable for patients with pyloric obstruction. After 3-5 days of gastrointestinal decompression, the patient can resume diet and gradually improve his condition, which indicates that the factors of spasm and edema have been eliminated and can continue to be observed. Repeat barium meal examination if necessary. If decompression is ineffective, it means that it is cicatricial stenosis, and surgical treatment must be taken. If there is evidence of malignancy, surgery should be performed actively.
