Patients with rectal prolapse may experience bleeding during bowel movements. The primary symptom of rectal prolapse is a protrusion of a swelling through the anus. Initially, the swelling is small and only protrudes during bowel movements, retracting on its own afterwards. As the condition progresses, due to a lack of contraction strength in the levator ani and anal sphincter muscles, the prolapse occurs more frequently and increases in size, requiring manual repositioning back into the anus after defecation. If not repositioned timely, the prolapsed intestinal tract can become edematous, constricted, or even necrotic, which may result in bloody stools.

The difference between rectal prolapse and rectal prolapse.

Rectal prolapse, also known as rectal prolapse, is characterized by partial prolapse of the rectal mucosa in the early stages and full-length prolapse of the rectum in the later stages. Early rectal prolapse is generally accompanied by a feeling of incomplete bowel movements, urgency followed by a feeling of incomplete relief, and perianal contact, with secretions leading to perianal eczema, itching, and infection in the later stages. If the prolapse cannot be reduced, entrapment can occur, causing pain. The initial treatment for rectal prolapse is to ensure smooth bowel movements and reduce factors that increase abdominal pressure to avoid causing the rectal mucosa to protrude outward. Severe rectal prolapse may require surgical treatment.

Causes of rectal prolapse

The causes of rectal prolapse primarily include older age or physical weakness leading to relaxation and sagging of the pelvic and rectal mucosa. Prolonged constipation can also lead to excessive straining during bowel movements, causing stress-induced sagging of the intestinal mucosa. Additionally, women who have gone through childbirth may experience rectal prolapse due to excessive straining of the pelvic floor muscles during delivery or increased abdominal pressure during pregnancy, which compresses the rectal mucosa. The treatment for rectal prolapse mainly consists of conservative medication or surgical removal. For mild cases of rectal prolapse, including those in children, traditional Chinese medicine enemas can be used. However, for moderate to severe cases, or cases where prolapse recurs frequently and significantly forms a complete prolapse, surgical removal is recommended.

Which department to consult for rectal prolapse?

Rectal prolapse is generally divided into internal mucosal prolapse and external prolapse. External mucosal prolapse is commonly known as rectal prolapse, which falls under the category of proctological diseases. Therefore, patients who suspect they have rectal prolapse should promptly visit a proctology department for relevant examinations and treatment. The examination and diagnosis of rectal prolapse mainly involve digital rectal examination, anoscopy, and defecography to confirm the diagnosis. Especially for internal mucosal prolapse, which cannot be seen with the naked eye, defecography is necessary for differentiation. In cases of rectal prolapse, one can generally see a ring-like protrusion outside the anus, and in severe cases, there may be conical or cylindrical prolapse. Regardless of whether it is internal mucosal prolapse or rectal prolapse, surgical treatment is necessary.

What is the pathogenic mechanism of rectal prolapse?

The pathogenic mechanism of rectal prolapse primarily refers to the relaxation and sagging of the rectal mucosa down to the anal area, forming an internal rectal mucosa prolapse. Excessive relaxation of the rectal mucosa can protrude externally through the anus in a cylindrical or conical shape, commonly known as external rectal mucosa prolapse or rectal prolapse. The causes are mainly due to congenital deficiency of kidney energy in patients or excessive relaxation of the rectal mucosa due to multiple childbirths. Some patients with long-term constipation may also experience rectal mucosal relaxation due to excessive straining during bowel movements. Additionally, elderly and frail patients may experience sagging of the rectal mucosa as they age.
