Later, the White Wall, Bear warehouse Zhu further study, that the shape of the ulcer (hereinafter referred to as wire ulcer) morphology, pathogenesis, clinical manifestations are different from the commonly seen circular, elliptical or non-plastic ulcer, with its Particularity. Its incidence accounts for 6.6 ~ 43.3% of gastric ulcer, accounting for 20 to 40% of surgical cases. Cracking occurs in a small bend, and more vertical movement with a small bend, but also with a small bend oblique or parallel walk. Its length from a few millimeters to tens of millimeters, some more than 100 millimeters. Most of the width of 4 ~ 5 mm. Depth of different, severe deep muscular, shallow ulcers are covered by regenerated mucosal epithelium, showing a state of cure, the majority of cases there are some unhealed ulcers exist, such as the collapse of the end of the line or in the middle of a garden ulcer.
