Do external hemorrhoids without any symptoms need treatment?
External hemorrhoids can be categorized into skin tag-like external hemorrhoids, varicose vein-like external hemorrhoids, and thrombosed external hemorrhoids. Most patients with skin tag-like external hemorrhoids do not have any sensations, and in such cases, treatment is not necessary. Patients only need to pay attention to the hygiene around the anal area. After each bowel movement, they should wash the anal area with clean water. They should also frequently change their underwear, and their diet should be light and easily digestible to avoid diarrhea or constipation. During bowel movements, it's important to ensure the process is smooth to avoid lengthy bathroom visits or excessive straining, which can prevent the exacerbation of skin tag-like external hemorrhoids, hence no treatment would be needed. However, for varicose vein-like external hemorrhoids or thrombosed external hemorrhoids, patients may experience a foreign body sensation or pain around the anus. In such cases, conservative treatment with medications can be considered initially. If conservative treatment is ineffective, surgical intervention may be required.
What should I do about internal hemorrhoids?
In clinical practice, the treatment of internal hemorrhoids mainly depends on the symptoms presented by the patient, and an appropriate treatment method is selected accordingly. For example, patients with early-stage internal hemorrhoids who experience intermittent rectal bleeding are usually advised to use hemorrhoid suppositories or ointments after defecation. However, as the condition of internal hemorrhoids worsens, which might include prolapse or even symptoms of anemia, surgical treatment is often recommended. Clinically, surgery for internal hemorrhoids can involve sclerotherapy injections, hemorrhoidal banding, or other surgical methods such as PPH (Procedure for Prolapse and Hemorrhoids) or TST (Transanal Hemorrhoidal Dearterialization). Post-surgery, dressing changes are necessary, and products such as rectal cleansing solutions, oil gauze strips, or ointments are commonly used. Moreover, it is crucial for patients to maintain smooth bowel movements post-surgery to avoid wound infection, bleeding, or edema, and they should adhere to a light diet avoiding spicy, stimulating, and dry foods. (Please follow medical advice regarding medication use.)
Does the surgical removal of external hemorrhoids hurt?
Surgical removal of external hemorrhoids generally does not cause significant pain because anesthesia is required for the procedure. There are options for anesthesia, including local infiltration anesthesia, spinal anesthesia, or general anesthesia via intravenous injection, ensuring the patient does not experience notable pain during the surgery. However, post-surgery sensitivity is higher because the external hemorrhoids are innervated by perineal nerves. Therefore, it is crucial to use pain relief medication appropriately when changing dressings to alleviate discomfort. Additionally, it is essential to prevent infection, inflammation, or swelling of the wound to reduce postoperative pain. Patients should also manage their bowel movements to avoid dry, hard stools; smooth bowel movements can somewhat relieve postoperative pain. If the pain is particularly severe, the use of diclofenac sodium suppositories for anal insertion can help reduce inflammation and pain. (Please follow medical advice regarding medication use.)
Is chemotherapy effective for late-stage rectal cancer?
Late-stage rectal cancer is primarily due to the metastasis and proliferation of cancer cells. At this stage, surgery alone cannot completely eliminate cancer cells, so chemotherapy is necessary. Chemotherapy has certain effects clinically, especially in patients who are sensitive to chemotherapy drugs, where the effects are more pronounced. This can control the spread of cancer cells in multiple locations and can, to some extent, improve patient survival rates. For patients, it is important to maintain good health, enhance their immune system, consume foods rich in high-quality proteins, and engage in appropriate exercise. Moreover, maintaining a positive mindset is beneficial for extending life. Additionally, patients can integrate traditional Chinese medicine and acupuncture as complementary therapies, which can also potentially improve postoperative survival rates.
Are hemorrhoids the same as anal fistulas?
Hemorrhoids and anal fistulas are two completely different diseases. Clinically, hemorrhoids can be divided into mixed hemorrhoids, internal hemorrhoids, and external hemorrhoids. Internal hemorrhoids are often characterized by intermittent, painless rectal bleeding, while external hemorrhoids primarily cause symptoms such as a foreign body sensation in the anus and itching. For the treatment of hemorrhoids, if the condition severely affects the patient's normal life, surgical treatment can be considered, such as external peeling and internal ligation surgery, and internal hemorrhoid banding. Anal fistulas are mainly due to perianal abscesses that rupture spontaneously or are incised and drained, subsequently forming an anal fistula, which causes the patient to experience recurrent perianal swelling pain and pus and bloody discharge. Treatment for anal fistulas can only be surgical, and early surgical intervention tends to result in relatively fast postoperative recovery. The surgery mainly involves the removal of the internal opening and the fistula tract, followed by diligent postoperative dressing changes to promote wound healing.
Can warm water sitz baths improve internal hemorrhoids that have prolapsed?
Warm sitz baths for prolapsed internal hemorrhoids can improve anal heaviness to some extent, and prevent inflammatory edema caused by the prolapse. They can also help prevent further worsening of prolapsed hemorrhoids, as warm sitz baths promote circulation around the anal area, relieve heaviness, and can somewhat reduce the prolapse, but they cannot completely cure it. Prolapsed internal hemorrhoids are caused by pathological hypertrophy and descent of the anal cushions, representing an organic lesion. Simple conservative medical treatment can only prevent the hemorrhoids from worsening, but cannot fully cure them. For prolapsed internal hemorrhoids that can be manually reduced, conservative treatment is generally recommended. Regular smooth bowel movements should be maintained, long duration of defecation should be avoided, and frequent anal sphincter exercises should be performed. However, for prolapsed hemorrhoids that cannot be reduced, or those that develop incarceration with edema or thrombosis, surgical treatment is recommended.
Can external hemorrhoids be eliminated?
External hemorrhoids can certainly be removed. Clinically, surgical treatment can be used to remove external hemorrhoidal masses. Hemorrhoidectomy is a common surgical option and can be performed under local infiltration anesthesia, spinal anesthesia, or general anesthesia. After surgery, it is crucial for patients to adhere to changing dressings to avoid infections, inflammation, or edema at the wound site. Dietary precautions should be taken as well; spicy, irritating, and dry foods should be avoided as much as possible. If patients prefer not to undergo surgery, medications can be considered for treating external hemorrhoids, though they can only reduce the size of the hemorrhoidal masses, not eliminate them entirely. Common treatments include anal washes and sitz baths, topical application of golden ointment, and when necessary, oral administration of Diosmin can help reduce swelling. Additionally, patients should regularly perform pelvic floor exercises and avoid prolonged or excessive straining during bowel movements.
What are the precautions after undergoing anal fistula surgery?
Because anal fistula surgery primarily involves removing the internal opening and the fistula tract, the postoperative wound is relatively large. Postoperative care mainly requires consistent dressing changes to ensure the wound drainage remains unobstructed, avoiding infection or false healing. Additionally, patients should develop good bowel habits, maintain smooth bowel movements, and avoid withholding stool. Otherwise, this may lead to dry, hard stools, causing severe pain during defecation or damaging the wound, which could result in bleeding or edema. In terms of diet, patients should choose foods rich in roughage to ensure smooth defecation and eat foods rich in high-quality protein to supplement the amino acids the body needs, promoting wound healing as much as possible. Moreover, after surgery, patients must use an anal wash or potassium permanganate solution for sitz baths. Since the postoperative wound is open and contaminated, changing dressings is especially important.
Can internal hemorrhoids be treated by prolapse and bloodletting?
Bleeding should not be used for prolapsed internal hemorrhoids, as this condition is primarily caused by improper defecation habits leading to pathological enlargement and descent of the anal cushion, which results in the prolapse of internal hemorrhoids. In the early stage, prolapsed internal hemorrhoids can retract back into the anus after defecation, and under such circumstances, it is only required for the patient to develop good bowel habits. For example, avoid spending too much time on defecation, don't exert excessive force, perform sphincter exercises after defecation, and maintain smooth bowel movements. Attention should also be paid to perianal hygiene; it is advised to wash the area with warm saline water after defecation to avoid worsening the prolapse or causing incarcerated edema. However, for cases where incarcerated edema occurs, it is generally recommended to consider prompt surgical intervention, such as hemorrhoidal ligation, PPH (Procedure for Prolapse and Hemorrhoids), or TST (Transanal Stapling Technique). The use of bleeding as a treatment does not have significant therapeutic effects for prolapsed internal hemorrhoids, and thus is not recommended in clinical practice. Furthermore, patients should pay attention to a light diet and avoid spicy, stimulating, and dry-hot foods as much as possible.
Does a recurrent perianal abscess occur in the same location?
The recurrence of a perianal abscess may not necessarily be in the same location, but it is possible. If the internal opening was not completely cleared during the first perianal abscess surgery, this could lead to reinfection of the anal glands and subsequently a recurrence of the perianal abscess. In such cases, it is advisable to visit a hospital early for a perianal MRI to determine the position of the internal opening and the extent of the infected tissue. Then, a one-time radical surgery for the perianal abscess can be performed. After the surgery, it is crucial to consistently use medications like red oil gauze, anal wash, and golden ointment for dressing changes, to promote wound healing and avoid pseudo-healing. Additionally, if a perianal abscess was completely cured once, poor diet, lack of sleep, or frequent alcohol consumption could potentially cause abscesses in other perianal areas later. This situation is quite common, so it is important for patients to maintain a light diet.
