Pathology shows inflammatory cell infiltration, indicating a lesion caused by inflammatory infection, which is benign and excludes the possibility of malignancy. If there is discomfort in the upper abdomen or lower abdomen with diarrhea, malignancy, vomiting and other symptoms, gastroscopy or colonoscopy can be performed if necessary. When the examination reveals polyps in the stomach or intestine, or lesions such as mucosal bulges, pathological examination is usually performed. If the pathological examination reveals inflammatory cell infiltration, the polyp is an inflammatory polyp, and anti-infection treatment is sufficient to exclude malignancy. If it is in the stomach, oral cefixime or clarithromycin is usually required. If it is an inflammatory polyp in the colon, oral antibiotic treatment such as cefixime is also needed. After treatment, the patient should be observed for pain in the abdomen and improvement in diarrhea. If necessary, a gastroscopy or colonoscopy should be performed after three or six months for review.
