| [ Summary ] |
Proctitis may occur in many diseases, such as ulcerative colitis, Crohn's disease, radiation induced proctcolitis, pseudomembranous colitis, infectious enterocolitis, sexually transmitted diseases, mucosal prolapse syndrome, or ischemic procto-colitis. Continuous mucosal inflammation of the proximal colon is pathognomonic of ulcerative colitis, ischemic proctitis, amoebic colitis, shigellosis, or pseudomembranous colitis. In countries, sexually transmitted diseases are called "gay bowel syndrome". In Japan, the number of patients with sexually transmitted disease is increasing. However, sexually transmitted diseases occur not only in homosexual men but also in heterosexual people in our country. |
