How should internal hemorrhoids be effectively treated?
The treatment methods for internal hemorrhoids are mainly divided into conservative treatment and surgical treatment. Conservative treatments include oral medications or topical medications, mainly aimed at relieving symptoms such as bleeding or prolapse during the remission phase, without addressing the pathological site. Surgical options include hemorrhoidal ligation, hemorrhoidectomy, PPH (stapled hemorrhoidopexy), and injection therapy, all of which are surgeries targeting the hemorrhoids themselves, and their effectiveness is generally quite definitive.
How to express fecal incontinence
Fecal incontinence, also known as anal incontinence, means that when the function of the anus is impaired, feces or intestinal fluid involuntarily leaks out of the anus. Therefore, it can be divided into two aspects: the first aspect is that some people only have incontinence of liquid stool, not solid feces; the other is that both solid and liquid stools are incontinent, both can involuntarily leak out, with the latter scenario being more severe. The causes are generally due to damage to the anus, congenital anomalies of the anus, damage to the anal sphincter, or diseases of the anus, among other reasons.
Early symptoms of rectal cancer
The early symptoms of rectal cancer generally include five main signs: The first early symptom is bloody stool, which is the earliest and most common symptom of rectal cancer. The second symptom is mucous bloody stool. Large cauliflower-like tumor masses generally secrete a large amount of mucus, which can cause mucous bloody stool. The third is a change in bowel habits. What does a change in bowel habits mean? It means that sometimes there can be diarrhea, sometimes constipation, or an alternation of constipation and diarrhea, indicating a change in bowel habits. There can even be changes in the shape of the stool, which is the third symptom. The fourth symptom is a feeling of heaviness or fullness in the perineum or anus. The fifth symptom can cause abdominal pain. It can cause pain in the lower abdomen, a sensation of a foreign body in the intestine, and even bloating. For instance, constipation can lead to difficulty in passing stool, which in turn can cause bloating and abdominal pain. These are primarily the five early symptoms.
How to reposition a prolapsed internal hemorrhoid?
Some internal hemorrhoids that prolapse can retract on their own, corresponding to second-degree internal hemorrhoids. If manual repositioning is required, these are typically third-degree or fourth-degree internal hemorrhoids. Third-degree internal hemorrhoids need to be manually repositioned because the external anal sphincter obstructs the retraction of the hemorrhoids. Generally, the method of taking a warm water sitz bath is used to relax the external anal sphincter, after which the hemorrhoids can be manually repositioned. During repositioning, applying some paraffin oil can facilitate the process, making it easier to accomplish.
How long does it take to recover from an anal fissurectomy?
Anal fissure refers to a small ulcer formed by the skin cracking below the dentate line of the anal canal, with the main symptoms being pain and bleeding. Anal fissure excision surgery is one of the surgical treatments for anal fissures. It mainly involves removing the anal fissure, the sentinel piles, and the hypertrophied anal papillae. It also involves cutting a part of the internal and external sphincter's subcutaneous section. The wound is left open for drainage. A disadvantage is that healing is relatively slow, so it generally takes over a month to fully recover after the surgery.
Can anal dilation treat external hemorrhoids?
Anal dilation cannot treat external hemorrhoids. Anal dilation, also known as anal canal dilation surgery, is a common surgical treatment method in proctology. It primarily involves using external force to increase the diameter of the anal canal in order to achieve the purpose of dilation. It is mainly used for patients with early-stage anal fissures and anal stenosis. External hemorrhoids, which grow below the dentate line of the anal canal skin, are not affected by anal dilation treatments.
What are the symptoms of anal fistula?
An anal fistula generally refers to a tract left behind after an anal abscess bursts on its own or is surgically opened. It usually consists of a primary internal opening and a secondary external opening. The main clinical manifestations, or primary symptoms, are: The first is discharge of pus, which occurs due to recurrent infections in the anal fistula; The second is pain. When the external opening is closed, the pus inside cannot drain properly, or when drainage is poor, this leads to accumulation of pus in the fistula tract, causing localized pain; The third is itching. Continuous irritation of the skin around the external opening by pus draining from the fistula tract can cause itching around the anus and may lead to symptoms like anal eczema.
What should I do if internal hemorrhoids prolapse and cause pain?
Generally, internal hemorrhoids do not cause pain. However, when internal hemorrhoids prolapse and become trapped outside the anus, leading to swelling, infection, or even necrosis, various degrees of pain can occur, which can be very painful. Therefore, when internal hemorrhoids prolapse and become trapped, surgery is required. Thus, hospitalization for surgery to relieve the trapped hemorrhoids is necessary to definitively cure the condition.
How to treat internal hemorrhoids stage II?
Internal hemorrhoids, according to the provisional standards for the diagnosis of hemorrhoids set by the Coloproctology Group of the Surgical Branch of the Chinese Medical Association in September 2002, stage II internal hemorrhoids primarily exhibit symptoms of bleeding during defecation. Additionally, the hemorrhoidal mass prolapses outside the anus during bowel movements but retracts back inside autonomously after defecation. This condition is referred to as stage II internal hemorrhoids, indicating the onset of symptoms like bleeding and prolapse, thus requiring surgical treatment. Indications for surgery include procedures like hemorrhoid banding or hemorrhoidectomy to remove the hemorrhoids. Conservative treatment options like using hemorrhoidal suppositories or ointments are also available if surgery is not immediately considered, but if these treatments are ineffective, surgery should be pursued. (Please use medications under the guidance of a physician to avoid misuse.)
Can anal fistulas be contagious?
An anal fistula is a pathological channel that forms a connection between the anal canal, rectum, and the skin around the anus. It primarily develops from an infection causing a perirectal abscess around the rectal anal canal. These infections are generally purulent, with a smaller number due to tuberculosis. Other specific infections, such as Crohn's disease or ulcerative colitis, can also lead to anal fistulas. Generally, such infections are caused by Escherichia coli, leading to purulent infections; tuberculosis can be contagious, but generally, it is not infectious or contagious.
