One of the manifestations of syphilis, spinal consumption, causes a variety of visceral crises, with gastric crises being the most common. Syphilis of the stomach is a rare gastric disease caused by the invasion of the stomach lining by syphilis spirochetes. Gastric syphilis is caused by syphilis spirochetes, and the lesions begin in the submucosa of the stomach. Early syphilis can involve the gastric wall, but most of them are transient, and the pathological changes of the gastric mucosa in the second stage of syphilis are not specific. Gastric lesions are mainly caused by stage III syphilis. So how to prevent gastric crisis? Prognosis: Patients who have been adequately treated should be followed up for 2 to 3 years after treatment and reviewed every 3 months during the first year, including clinical and serum (non-spirochete antigen test), and every 6 months thereafter. During the follow-up period, observe closely the decrease of serum reaction titer and clinical changes, and terminate the observation if there is no recurrence. Prevention: 1. Within 3 months, any sexual partner who has been in contact with infectious syphilis should be examined, diagnosed and treated. 2, early syphilis in the treatment period to prohibit sexual intercourse.
