What is the best treatment for a minor anal fissure?
Minor anal fissures, which are early-stage fissures, mainly manifest as pain during defecation and minor bleeding, but the pain does not last long and is primarily associated with defecation. For minor fissures, it is generally recommended to choose conservative treatment with medications and dietary regulation to ensure smooth bowel movements. Typically, after defecation, one can choose to use an anal cleansing solution or a potassium permanganate solution for a sitz bath. After the sitz bath, apply Dragon Ball ointment or nitroglycerin ointment locally to promote the healing of the ulcerated surface. At the same time, in terms of diet, one should drink more water and consume foods rich in dietary fiber to maintain smooth bowel movements as much as possible, avoiding dry and hard stools, which also helps in the healing of minor anal fissures. Additionally, patients should pay attention to keeping the anal area dry and clean, avoid irritating the wound, and prevent infection that could exacerbate the condition.
Can a perianal abscess burst on its own after it forms pus?
After an anal abscess becomes purulent, one should not attempt to rupture it on their own. If purulence occurs, it is advised to perform local disinfection under a doctor's supervision, followed by incision and drainage or pus aspiration to prevent further infection. Attempting to rupture it on your own can easily lead to further aggravation of the local infection. After an anal abscess becomes purulent, the choice of incision location is crucial; once cut, it is necessary to maintain unobstructed drainage to avoid subsequent infection or even necrotizing fasciitis. In clinical practice regarding anal abscesses, it is advised to visit a colorectal surgery department at a hospital as soon as the abscess is detected, to undergo procedures such as incision and drainage or radical surgery of the anal abscess to avoid the later development of anal fistulas or necrotizing fasciitis. Post-surgery, medications such as red oil gauze strips, anal cleansing solutions, and aureomycin ointment are recommended for dressing changes.
How to differentiate rectal cancer from hemorrhoids
Rectal cancer is a malignant lesion, with clinical symptoms mainly causing an increase in the frequency of bowel movements, changes in stool characteristics such as grooved stools or stools with mucus and pus and blood. Severe patients may experience abdominal pain, weight loss, anemia, and other accompanying symptoms. Generally, low-lying rectal cancer can be seen during a digital rectal examination or with an anoscope. If the cancer is located higher up, an electronic colonoscopy is needed to see the cauliflower-like mass. Hemorrhoids, on the other hand, are benign lesions often caused by improper diet or poor bowel habits, leading to pathological hypertrophy and descent of the anal cushions. They are mostly characterized by intermittent painless rectal bleeding with bright red blood, along with a feeling of heaviness and a foreign body sensation in the anus.
How to relieve the pain of hemorrhoids
Most of the time, hemorrhoids do not cause pain. Pain from hemorrhoids is often considered to be due to inflammatory swelling, external hemorrhoid rupture, or thrombosis formation, which leads to pain. If you want to relieve the pain promptly, you can choose sodium diclofenac suppositories for anal insertion, which can have anti-inflammatory and analgesic effects. Later, after defecation, you can use anal washes or potassium permanganate solution for sitz baths, in conjunction with hemorrhoid cream for external application and oral Diosmin tablets to reduce swelling. If the symptoms do not improve significantly after four to five days of medication, it is necessary to go to the hospital’s coloproctology department for hemorrhoid surgery as soon as possible, such as hemorrhoidectomy, external hemorrhoid excision, and TST. Post-surgery, it is important to adhere to dressing changes to promote wound healing, and maintain smooth bowel movements.
