What Does Dilation of the Anal Canal Mean?

Anal dilatation, also known as anal canal dilation, refers to a method of dilating the anus using fingers or instruments under local anesthesia or general anesthesia. It can be used for the examination and treatment of anorectal diseases. Patients can consult professional doctors for specific conditions. Anal dilatation is a common treatment method in anorectal surgery. Simple anal dilatation can stimulate the defecation reflex of the anus, improve constipation symptoms in patients with intestinal obstruction, and can also be used for the examination and treatment of anorectal diseases such as anal fissures, internal hemorrhoids, and partial anal stenosis. Performing anal dilatation before surgery can also fully relax the anus, facilitating the surgery. The basic requirement of anal dilatation is to operate according to the tightness of the anal sphincter, and it is suitable for anal fissures in stages 1-2 and without conditions such as sentinel piles. During anal dilatation, it is necessary to ensure complete anesthesia and perform the action gently. Violent and rapid dilation of the anus is not recommended to avoid multiple tears in the mucosa or anal canal. The procedure should be performed under the guidance of a professional doctor and should not be attempted by oneself to prevent unnecessary damage to the anus and affect normal life. Anal dilatation can easily cause certain irritation to the rectum and may introduce some bacteria, inducing rectitis. Improper operation may also lead to damage to the anal sphincter, causing anal incontinence. In daily life, patients need to develop good bowel habits, eat a light diet, and avoid spicy and stimulating food. If there are abnormal conditions in the body, they should seek medical attention promptly to avoid delaying the condition.
