From the point of view of modern medicine, anal dilatation can be caused by many diseases, which is a symptom that can not be ignored. The author has met several cases of anal distension in clinic, which were confirmed as middle and advanced rectal cancer by examination.
Usually, the most common cause of anal dilatation is inflammatory diseases, such as anal sinusitis and proctitis. In addition, anorectal diseases such as internal hemorrhoid prolapse, rectal prolapse, external hemorrhoid prolapse, anal nipple hypertrophy, anal papilloma and low rectal polyp can also feel anal dilatation. Clinically, it is also found that anal dilatation in a few patients is caused by anorectal neurosis and fecal impaction.
It is precisely because patients with anal dilatation may suffer from anorectal cancer. Therefore, as long as there are symptoms of anal dilatation, it is necessary to seek medical treatment as soon as possible, go to the hospital for anorectal examination, make a clear diagnosis, and pay close attention to treatment to avoid the continuous aggravation and deterioration of the condition.
Even inflammatory diseases such as anal sinusitis should be treated in time, otherwise it may develop into more serious diseases, such as anal inflammation, perianal swelling, anal fistula and so on.
However, it must be pointed out that if internal hemorrhoids are treated by injection, ligation, ligation and other methods, it is a short-term normal reaction. With the passage of time, Yin He's face gradually heals, and anal swelling will eventually disappear naturally.
