Will rectal prolapse cause the stool to become thinner?
Patients with rectal prolapse may experience a narrowing of their stool, which is primarily due to the relaxation of the rectal mucosa associated with rectal prolapse. The relaxed mucosa accumulates at the anus, blocking the passage of feces and thus altering the shape of the stool as it is expelled, generally resulting in thinner or flattened stools. Therefore, if it is definitively diagnosed that the change in stool shape is due to rectal prolapse, surgical treatment is recommended. The surgery involves excising or suturing the excessively relaxed rectal mucosa to allow for a smoother passage of stool and to prevent alterations in stool shape. Additionally, it is important for patients to maintain good lifestyle and bowel habits post-surgery, spend minimal time defecating, and avoid prolonged squatting or straining actions.
The difference between rectal polyps and internal hemorrhoids
Rectal polyps are skin-like mucosal protrusions that grow on the rectal mucosa, whereas internal hemorrhoids are confined to congestion and protrusion of the mucosa around the dentate line. The formation of rectal polyps is mainly due to long-term stimulation by feces, or certain constitutional and genetic factors, while the most likely cause of internal hemorrhoids is chronic congestion and edema around the anal area or the formation of venous thrombosis, leading to local varicose clusters. After the discovery of rectal polyps, it is necessary to perform surgery as soon as possible; however, the treatment for internal hemorrhoids in the early stages is primarily conservative, aimed at delaying the frequency of disease attacks and improving the quality of life for the patient. If the internal hemorrhoids reach a later stage or become severe, manifested by recurrent prolapse and rectal bleeding, surgical removal is recommended.
What are the effects of external hemorrhoid fumigation and washing liquid?
Shrink hemorrhoids, eliminate swelling. For the treatment of external hemorrhoids, one can choose Chinese herbal washes to fumigate the affected area, apply hot compresses, or take sitz baths. Their primary efficacy is to shrink the local external hemorrhoidal nodules and reduce swelling through the effects of the medication, or to enable the self-absorption of thrombosis and varicose veins within the local nodules. Beyond local fumigation agents, the treatment of external hemorrhoids can also include applying ointments or using suppositories. It is also necessary to maintain good bowel habits to avoid further irritation and enlargement from stool. If repeated treatment for external hemorrhoids is ineffective, or if the local symptoms are severe, surgery may be considered to remove the external hemorrhoids completely.
What causes anal fistulas?
The most common cause of anal fistula is perianal abscess. Both anal fistula and perianal abscess involve infections at the anal crypts. Typically, an anal fistula forms naturally after a perianal abscess ruptures. Once an anal fistula occurs, it requires prompt surgical treatment. The primary surgical technique is fistulotomy with seton placement, thoroughly removing the local lesion and infection focus to allow fresh granulation tissue to regrow. Anal fistula is a local infectious disease of the anus, generally categorized into simple superficial anal fistula and high-risk complex anal fistula. If a high-position complex anal fistula is suspected, further diagnosis may require additional examination with pelvic MRI or perianal ultrasonography. After the rupture of a perianal abscess, it typically forms a characteristic internal and external opening, with a fistula tract connecting them, thereby forming the typical anal fistula.
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.
Can internal hemorrhoids lead to anemia?
Internal hemorrhoids bleeding easily leads to anemia in patients, especially when internal hemorrhoids bleed frequently and recurrently, or each bleeding episode is relatively severe, potentially causing a trend of decreased blood volume in patients. When blood volume reaches a certain threshold, symptoms of anemia can appear. If the anemia is assessed as mild or moderate, besides using local hemostatic hemorrhoid creams or suppositories, patients can also take oral traditional Chinese medicine that supplements qi and generates blood for symptomatic treatment, to enhance body immunity and physical constitution. If anemia primarily presents as severe, to avoid further exacerbation of anemia or impairment of overall organ functions, it is recommended that patients undergo surgical ligation for hemostasis and, if necessary, blood transfusion. (Medication should be used under the guidance of a doctor.)
What's causing hemorrhoids to itch?
Hemorrhoids cause secretions to flow out from within the anal canal, particularly in the case of internal hemorrhoids. When severe, these secretions can flow outside the anus due to changes in the position of the anus or the patient's body, irritating the local skin and mucosa around the anus, thus leading to symptoms of itching. Additionally, with repeated prolapse of internal hemorrhoids, the mucosa may get trapped at the anal opening and cannot retract normally, also causing irritating itching and possibly even pain and bleeding due to repeated friction. To treat the itching from hemorrhoids, it is first necessary to alleviate the increased secretion from internal hemorrhoids. Options include using anti-inflammatory suppositories or gels, and washing the anal area with saline water or herbal washes that have antipruritic effects.
Can you get pregnant with rectal prolapse?
Patients with rectal prolapse can become pregnant, but if diagnosed with rectal prolapse before pregnancy, it is advisable to first surgically remove the prolapsed mucosa. This is because during pregnancy, as the fetus grows, the pressure in the abdominal cavity gradually increases. Female patients may experience worsening of the rectal prolapse due to increased abdominal pressure, which could lead to increased congestion and edema, thereby exacerbating the severity of existing hemorrhoids or the severity of the rectal prolapse. Therefore, if there are symptoms of rectal prolapse before pregnancy, surgical treatment is recommended. If rectal prolapse occurs during pregnancy, conservative treatment with traditional Chinese medicine enemas can be chosen, and surgery can be considered after childbirth.
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.
How is rectal prolapse graded?
Rectal prolapse is generally graded into three degrees: first degree rectal prolapse, second degree rectal prolapse, and third degree rectal prolapse. First degree rectal prolapse is a relatively minor condition where the rectal mucosa protrudes but can retract back on its own. Second degree rectal prolapse is a moderate condition where the protruding mucosa extends approximately 5-10 centimeters, generally forming a conical shape, and requires the patient to manually reposition it. Third degree rectal prolapse indicates a severe condition, with the prolapsed mucosa typically extending beyond 10 centimeters. It may protrude with each incident and could also occur when the patient strains the abdomen or squats. The treatment of second and third degree rectal prolapse generally requires surgical intervention.
