There is a lump of flesh outside the asshole

A lump of flesh at the anus is usually mistaken for hemorrhoids, and people do not go to the hospital for a diagnosis. Instead, they use hemorrhoid cream to treat it directly, or mistakenly think that it does not affect anything and do not treat it, thus delaying the best time to treat anorectal diseases. But in fact, in addition to hemorrhoids, the fleshy lumps at the anus may also be caused by rectal prolapse, rectal polyps or rectal leiomyosarcoma. You need to go to the hospital to confirm which disease it is. Now let's take a look at the main symptoms of rectal prolapse and rectal polyps.

Rectal prolapse

Partial downward movement of the rectal wall, that is, downward movement of the rectal mucosa, is called mucosal prolapse or incomplete prolapse; downward movement of the entire layer of the rectal wall is called complete prolapse. If the rectal wall moves downward within the anorectal cavity, it is called internal prolapse; if it moves downward outside the anus, it is called external prolapse. Rectal prolapse often occurs in children and middle-aged and elderly women. Rectal prolapse in children is mostly mucosal prolapse and usually heals on its own before the age of 5. Complete rectal prolapse in adults is rare. Repeated rectal prolapse can lead to pudendal nerve damage and anal incontinence, and there is a risk of rectal ulcers, bleeding, stenosis and necrosis, requiring surgical treatment.

The main symptom is a mass protruding from the anus. The swelling is small at first, falls out during bowel movements, and repositions itself after bowel movements. Later, the tumor prolapsed more frequently and increased in size, and needed to be pushed back into the anus by hand after defecation, accompanied by an incomplete bowel movement and a feeling of falling. Finally, it can be removed by coughing, exerting force or even standing. As prolapse worsens, it causes varying degrees of anal incontinence, often with mucus flowing out, leading to eczema and itching of the skin around the anus. Due to the difficulty in emptying the rectum, constipation often occurs, the frequency of bowel movements increases, and the stool is sheep-dung-like. The mucosa is eroded and blood flows out after rupture.

The symptoms of internal prolapse are not obvious, and are mainly manifested by symptoms of rectal emptying disorder such as a feeling of incomplete defecation and anal obstruction. Suppositories are inserted into the anus to assist bowel movements and make bowel movements smoother. Some patients experience distension and pain in the lower abdomen and lumbosacral region during defecation. Longer course of disease may also cause varying degrees of anal incontinence.

During the examination, the patient needs to squat and hold his breath to cause the rectum to prolapse. Partial prolapse can be seen as a round, red, smooth-surfaced mass with radial mucosal folds; the prolapsed length generally does not exceed 3 cm; digital examination only touches two layers of folded mucosa; if it is complete rectal prolapse, the surface mucosa has "concentric ring" folds; the prolapse is longer, and the prolapsed part is composed of two layers of intestinal wall folds, which are thicker when palpated; when the anal canal is not prolapsed, there is a deep annular groove between the anus and the prolapsed intestinal canal.

Rectal polyps

The clinical symptoms of colorectal polyps are often not obvious. Even if certain gastrointestinal symptoms occur, such as abdominal distension, diarrhea, constipation, etc., they are often ignored because they are mild and atypical. Generally, patients come to the hospital with blood in their stool, blood in their stool, or bloody and mucous stool. These diseases are often misdiagnosed as anal diseases such as hemorrhoids or "dysentery", thus delaying the necessary examinations. Anyone with unexplained blood in the stool or gastrointestinal symptoms, especially middle-aged and elderly men over 40 years old, should pay attention to further examination and diagnosis.
