The difference between rectal prolapse and rectal prolapse
The term "rectal prolapse" used in folk vernacular covers a wide range, such as incarcerated hemorrhoids, inflammatory external hemorrhoids, thrombosed external hemorrhoids, rectal polyps, and rectal prolapse itself are all referred to as rectal prolapse. Of course, this also includes cases where, due to a lack of medical knowledge, any tumors or flesh-like growth protruding from inside to outside the anus are collectively termed as rectal prolapse. It is evident that the folk term “rectal prolapse” includes conditions like prolapsed rectum, prolapsed internal hemorrhoids, or prolapsed polyps, while the modern medical definition of rectal prolapse specifically refers to the protrusion of the rectum and its mucous membrane; the two should not be confused.
What foods should be avoided with anal fissures?
People with anal fissures should avoid consuming chili peppers and alcohol. Chili peppers contain a compound called capsaicin, which can strongly irritate the nerves in the gastrointestinal tract and the ulcers of anal fissures, causing severe pain in the affected area. Additionally, capsaicin can dilate the mucosal blood vessels, leading to bleeding in the anal fissures. Alcohol has a similar effect, as it can exacerbate congestion and blood stasis in the anal and rectal areas. In most cases, consuming chili peppers and alcohol can intensify the pain.
The harm of internal hemorrhoids prolapse
Prolapsed internal hemorrhoids are one of the main clinical manifestations of internal hemorrhoids, and their harm is mainly manifested in two aspects: Firstly, the prolapse of hemorrhoidal tissue outside the anus can lead to perianal skin eczema and itching, and anal eczema. Secondly, it can lead to incarcerated hemorrhoids, where the prolapsed internal hemorrhoid, held by the sphincter, forms congestion, and is accompanied by hardening of the hemorrhoidal tissue, pain, and even necrosis.
Clinical Characteristics of External Hemorrhoids
External hemorrhoids refer to hemorrhoids located below the dentate line, which are classified into four main types, each with distinct clinical manifestations. Connective tissue external hemorrhoids and varicose vein-type external hemorrhoids primarily present with a mild sensation of a foreign body in the anus. Inflammatory external hemorrhoids are characterized by redness, swelling, protrusion, burning, or itching of the anal skin or skin tags. Thrombosed external hemorrhoids often occur after intense exercise or straining during bowel movements, suddenly presenting as a round or oval lump under the skin at the edge of the anus. This lump contains a venous thrombus and is accompanied by anal pain.
Can anal fistula be completely cured?
Anal fistulas rarely heal naturally, and surgery is the only treatment method to achieve healing. The reasons are as follows: Aside from an external opening on the skin around the anus, an anal fistula also has a primary infectious internal opening in the anal crypt. The two openings are interconnected, allowing bacteria and intestinal contents to enter the fistula tract through the internal opening, leading to recurrent infections. Persistent inflammation often prevents pus from draining through the external opening. There are complex relationships between the fistula and the sphincter muscles, and the frequent contraction and relaxation of the sphincter muscles can compress the tract, making it easy for pus to remain and cause infection. Therefore, surgery is necessary to completely cure an anal fistula.
Precautions for Internal Hemorrhoids Bleeding
Rectal bleeding is the primary clinical manifestation of internal hemorrhoids. When rectal bleeding occurs, it's essential first to rule out whether the bleeding is definitely from internal hemorrhoids because rectal bleeding can be caused by many diseases, including malignant tumors. Once it's determined that the bleeding is from internal hemorrhoids, it is important to pay attention to whether the volume of blood is large, the duration of bleeding is long, and the frequency of bleeding is high, and whether there is frequent or daily bleeding. If so, it will exceed the body's ability to replenish blood through its hematopoietic function, leading to severe systemic anemia.
Do external hemorrhoids always require surgery?
Simple external hemorrhoids do not necessarily require surgery. External hemorrhoids are mainly those that grow below the dentate line, and their main clinical manifestation is a foreign body sensation in the anus, which does not pose a significant risk to the body. Only thrombosed external hemorrhoids with obvious anal pain may not require surgery if the lump is small, as the thrombus can be absorbed on its own. Only those with large lumps need to have the thrombus removed to alleviate pain.
What is good to eat after rectal cancer surgery?
Patients who have undergone surgery for rectal cancer should pay attention to the following points regarding their diet: First, consume a moderate amount of foods containing monounsaturated fatty acids, such as olive oil and tuna. Second, avoid overheating animal products and vegetable oils during cooking. Third, eat more foods rich in dietary fiber, such as konjac, soy and its products, fresh vegetables and fruits, and algae. Fourth, intake vitamins and trace elements by eating fresh vegetables and fruits to supplement carotene and vitamin C, and consume appropriate amounts of walnuts, peanut milk, products, and seafood to supplement vitamin E. Pay attention to the intake of foods rich in the trace element selenium, such as malt, fish, and mushrooms.
"Internal hemorrhoids prolapse" means internal hemorrhoids have slipped downwards, typically so they protrude outside the anus.
Prolapse of internal hemorrhoids refers to the condition where the hemorrhoidal mass of internal hemorrhoids protrudes outside the anus. This condition occurs only in internal hemorrhoids of grade II or higher. Grade II internal hemorrhoids can spontaneously retract back inside the anus after defecation without the need for manual reduction. Grade III internal hemorrhoids, however, do not retract spontaneously and should be manually reduced after cleaning and a period of bed rest. If the hemorrhoids remain prolapsed for a long time without timely reduction, it can lead to painful swelling around the anus. If a patient is unable to manually reduce the prolapsed hemorrhoids themselves, it can lead to incarcerated hemorrhoids, and medical assistance should be sought promptly.
Can rectal prolapse cause bleeding during bowel movements?
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.
