what does a hemorrhoids look like,Chapter One What are the common anorectal diseases?

    I often talk about this problem when I give lectures to students in class, and now I also talk about it to friends of patients. Broadly speaking, various diseases that occur on the anus and large intestine are called anorectal diseases, and hemorrhoids and anal fistulas are the most common. Therefore, in ancient China, anorectal diseases are collectively referred to as hemorrhoids and more than 100 common diseases. In a narrow sense: various diseases that occur on the anus and rectum, the most common are more than 30 kinds, such as: hemorrhoids (internal hemorrhoids, external hemorrhoids, mixed hemorrhoids), perianal abscess, anal fistula, anal fissure, anal papilloma, rectal cancer, Functional constipation, anal sinusitis, proctitis, rectal ulcer, rectal prolapse, rectal protrusion, rectal mucosal prolapse, anorectal stenosis, anal incontinence, rectal polyps, anal skin diseases, anorectal tuberculosis, anal neurosis , Condyloma acuminatum, anorectal congenital malformations, anorectal trauma, etc. Of course, for patients and friends, it is enough to simply understand some common anorectal diseases such as hemorrhoids and anal fistulas in a narrow sense. Later, I will summarize the causes, symptoms, diagnosis, treatment, surgery, pre- and post-surgery precautions and prevention of the most common anorectal diseases for patients and friends for reference.
