How does peptic ulcer check?
Both fiber gastroscope and electronic gastroscope are the main methods to diagnose peptic ulcer. Under the direct vision of endoscopy, peptic ulcer is usually round, oval or linear, with sharp edge, basically smooth, covered by grayish white or grayish yellow coating, and the surrounding mucosa is congested, edematous and slightly uplifted.
The main X-ray images of peptic ulcer are niches or niches, which are caused by barium suspension filling the sunken part of the ulcer. In the front view, the niche is round or oval with neat edges. Because of the inflammatory edema around the ulcer and the formation of annular translucent area.
The detection methods of HP infection can be roughly divided into four categories: ① direct detection of HP from gastric mucosa, including bacterial culture, tissue smear or section staining and microscopic examination of bacteria; ② The activity of urease in stomach was determined by urease test, respiration test and urea nitrogen test; ③ Anti HP antibody was detected by serology; ④ Hp-dna was determined by polymerase chain reaction (PCR). Bacterial culture is the most reliable method for the diagnosis of HP infection.
