Pain and discomfort in the rectum and anus

Introduction Anorectal pain is the most common symptom of anorectal disease. Due to the relationship between anatomy and physiology, the pain of anorectal disease occurs mostly in the lower abdomen, perineum, anal margin and lower rectum.

Cause

Diseases that cause anal pain can be divided into two categories depending on the cause of the pain.

(1) Anal pain and defecation related persons:

The patient felt a burning pain during defecation, and a periodic severe pain after defecation, which often lasted for ten minutes to several hours. This condition was mostly caused by an anal fissure.

The patient has a history of internal hemorrhoids prolapse. Most of the pain is caused by internal hemorrhoids after defecation, causing local edema and persistent pain. This condition is mostly strangulated guilt.

When the patient feels defecation, a certain acupuncture-like pain on one side of the anus, a few minutes after defecation, the pain will naturally disappear, mostly anal cryptitis.

Sudden pain occurred during defecation, a purple-black round mass appeared on the side of the anal side skin, and the edema was severe, and accompanied by persistent pain, should be considered thrombotic external hemorrhoids.

(2) Anal pain is not related to defecation:

Unexplained redness around the anus, accompanied by systemic symptoms such as fever, pain around the anus and pain in the anal canal, jumping pain, and constantly increasing, sometimes the mass around the anus can touch the lumps, and some have a sense of falling, mostly Symptoms caused by infection around the anus.

If there is a long-lasting, increasing aggravation of the anus, accompanied by a drop in the sense of falling and the number of stools, occasionally can touch the irregular lumps in the anus, should be suspected of anal canal cancer.

There are also a few anal pains caused by foreign bodies. Some people eat chicken bones, fish bones, and shelled melon seeds. They are invaded in the anal canal, and there will be sudden pain in the anus. The pain will increase when the stool is severe. There are also cases where the foreign body is pushed by the anus.

There are some dysfunctions in the rectum, which are mostly clinical manifestations of mild UC. Although there are recurrent episodes, it can be self-limiting. Because the lesion is only located in the rectum, it is a characteristic, triad of proctitis with lower abdominal pain, constipation, and a small amount of bleeding. Mucosal exudation and hemorrhage often attach to the surface of the feces. Sometimes bleeding is the main manifestation, and the diagnosis of hemorrhagic proctitis is quite common. The general symptoms are mild, with little weight loss, anemia, hypoproteinemia and so on.

Differential diagnosis

Anorectal pain: It is the most common symptom of anorectal disease. Due to the relationship between anatomy and physiology, the pain of anorectal disease occurs mostly in the lower abdomen, perineum, anal margin and lower rectum.

Rectal and anal stenosis: refers to the narrowing, deformation or varying degrees of intestinal obstruction of the anus, anal canal and rectum, called anal and rectal stenosis. Due to the stenosis, the anal stenosis and rectal stenosis (more than 2.5-5 cm above the dentate line or the rectum of the rectum), the stenosis is often within 10cm, which is related to the nature of the primary lesion, the upper end of the stenosis is dilated, and the stenosis continues. Smashed. Ulcers, formation of epilepsy or replaced by other tissues. This disease can generally provide important information for the diagnosis, but the upper lesion is more concealed, and multiple tests should be performed to make a correct diagnosis.

Anorectal malformation: It is a common gastrointestinal malformation. It has many kinds of pathological complexities. Not only the anorectal itself has developmental defects, but also the muscles around the anus - the puborectalis, the external anal sphincter and the internal sphincter have different degrees of changes. The nervous system is also changed. One of the important changes in this malformation, in addition to the high incidence of malformations associated with other organ malformations, some cases of multiple malformations or severely endanger the life of the sick child.
