Rectal prolapse treatment
Rectal prolapse is primarily categorized into mild rectal prolapse as well as moderate and severe rectal prolapse. Mild rectal prolapse generally occurs in the early stages of the illness or in children and can be treated conservatively. Conservative treatment mainly involves Chinese herbal retention enemas. On the other hand, moderate and severe rectal prolapse can result in the protrusion of the local mucosa outside the anus, presenting as cylindrical or cone-shaped prolapses. Treating moderate to severe hemorrhoidal prolapse requires surgical intervention. The main surgical methods include hemorrhoidal mucosectomy with stapling and local submucosal sclerosant injections. It is also important to caution postoperative patients against squatting for long periods or straining during constipation, as these actions can exacerbate symptoms of submucosal prolapse.
Difference between colon polyps and colon cancer
Colon polyps and colon cancer both belong to organic tumors of the colon mucosa, but the fundamental difference is that colon polyps are mostly benign, while colon cancer is a malignant cancer of the intestines. Both colon cancer and colon polyps require examination by electronic colonoscopy for a definitive diagnosis, and further pathological examination is needed. After the detection of colon polyps, it is necessary to promptly perform radiofrequency ablation surgery under electronic colonoscopy. After the detection of colon cancer, it is necessary to complete relevant pelvic and systemic examinations, and after clarifying the local lesions, surgical removal is performed. Postoperatively, based on the size of the cancerous mass and the extent of the lesion, radiation therapy or chemotherapy may be required.
Can fecal incontinence be recovered?
If fecal incontinence occurs, the first step is to identify the main cause of the fecal incontinence. If it is caused by relaxation of the anal sphincter and anal canal, then surgery can be performed to tighten this area, specifically through an anal tightening procedure, which can restore control over fecal incontinence. If the patient has other underlying diseases or is elderly and frail, accompanied by changes in the nervous system, the symptoms of fecal incontinence may be alleviated through medication or physical therapy, but complete recovery is unlikely. This is because the recovery of the nervous system requires the integrated regulation of other bodily organs and functions. If there are multiple underlying diseases or if the patient is elderly and frail, especially in the later stages of coma, recovery is difficult.
How should a perianal abscess be treated effectively?
During the acute phase of a perianal abscess, there is generally severe pain in the anal area, accompanied by redness and throbbing of the skin, and there may be a pus cavity or pus encapsulation under the skin. The treatment of perianal abscess is mainly surgical. The surgical method is incision and drainage, combined with a one-time radical surgery. If the infection involves the local sphincter or has already formed a clear fistula, further incision and ligation surgery may be required. After surgery, it is necessary to thoroughly disinfect and change the dressings of the wound to prevent excessive granulation or the formation of false healing at the local wound. Postoperative diet should consist mainly of light, liquid foods, and spicy and irritating foods should be avoided.
How to relieve pain from thrombosed external hemorrhoids?
The main cause of pain in thrombotic external hemorrhoids is the thrombus within the local hemorrhoid nucleus, which increases the congestion pressure and leads to discomfort and pain. During the acute phase of thrombotic external hemorrhoids, there is generally pain or bloating in the local area, along with difficulty in defecation. To quickly alleviate the pain, one can manually break the local thrombus or use traditional Chinese medicine washes for hot compresses to promote the absorption of the thrombus. If the thrombus is large or the condition is severe, surgery can also be performed to peel and remove the local thrombus, which is the most effective method for pain relief. After the surgery for peeling off thrombotic external hemorrhoids, it is necessary to disinfect the local wound surface to avoid infection.
Can fecal incontinence be cancer?
The most common causes of fecal incontinence are neurological dysfunction or relaxation of the local anal sphincter. In some cases of advanced rectal cancer, excessive tumor growth can enlarge the local intestinal contents, leading to involuntary expulsion of feces. Diagnosis involves further examination using electronic colonoscopy, digital anal examination, and assessment of neurological function. If the cause is related to a neurological disorder, treatment by a neurologist is required. If the cause is relaxation of the anal sphincter, then anal sphincter tightening surgery may be considered. In cases where fecal incontinence is caused by an intestinal tumor, surgery to remove the tumor is recommended, along with radiation or chemotherapy.
What medicine is used for thrombotic external hemorrhoids?
Thrombosed external hemorrhoids generally result from the formation of blood clots inside the local external hemorrhoids, causing acute symptoms. During an episode of thrombosed external hemorrhoids, patients experience localized pain or a feeling of constriction, and the formation of dark red or purplish external hemorrhoids can be visibly seen at the anus, which are very painful to the touch. Treatment for thrombosed external hemorrhoids primarily involves topical medications or surgery. If the symptoms are mild, one may choose to apply hemorrhoid cream or use diluted saline solution to compress and reduce swelling. Surgery can also be opted to excise and remove the affected external hemorrhoids. Thrombosed external hemorrhoids generally occur in individuals who strain excessively during defecation or after extreme fatigue. Therefore, if accompanied by dry stools, it is necessary to use stool softeners to help lubricate and ease bowel movements for treatment.
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.
