Hemorrhoids are a common, multifaceted clinical condition. There are various treatment options for hemorrhoids, including conservative treatment, outpatient non-surgical treatment and surgical treatment. Modern minimally invasive anorectal technology has moved from the rough and tumble of the past to refinement and scarlessness, and in the face of different aesthetic positioning and diverse requirements, international quality anorectal treatment technology has become completely different from traditional anorectal surgery. Minimally invasive treatment of hemorrhoids RPH mucosal ligation on hemorrhoids Use: Apply an automatic hemorrhoid ligature to ligate a certain amount of mucosa and submucosal tissue above the hemorrhoid nucleus at an appropriate location 1.5-3cm above the dentate line, or directly at the upper edge of the base of the hemorrhoid nucleus. Treatment principle: After ligation, the mucosa is wrinkled and the anal cushion is lifted, eliminating the symptoms of prolapse. The local inflammatory reaction causes adhesion of the mucosa, submucosa and superficial muscle layer, and the anal cushion is fixed in a higher position to prevent re-prolapse. Partial blockage of the blood supply to the hemorrhoid improves venous backflow, thus reducing congestion hypertrophy or blood stasis in the hemorrhoid and causing the nucleus to shrink. Direct ligation of the upper edge of the base of the hemorrhoid nucleus provides immediate hemostasis. Therapeutic effect: The rubber band ligation is currently recognized as one of the most effective therapies and is the treatment of choice in Europe and America. Many clinical studies in Europe and the United States have shown that of all the non-surgical treatments, collar ligation has the best efficacy. Advantages of surgery: practical, simple, safe and effective. The pain is mild and complications are rare. No scar is left after surgery, and the normal structure and appearance of the rectum and anal canal are preserved as much as possible. Post-operative precautions: 1. drink more water and eat more foods with high fiber (such as vegetables and fruits), etc.; 2. keep the bowels open after surgery and prohibit spicy and alcoholic foods; 3. use sitz baths, topical ointments, anal suppositories, etc., and use antibiotics as appropriate; 4. some patients have a feeling of swelling after surgery, which can be relieved by symptomatic treatment.
