Hemorrhoidal edema cannot be trimmed, but if conservative treatment with medication is ineffective after the onset of hemorrhoidal edema, surgery may be considered. The process includes preoperative preparation, surgical anesthesia, starting the surgery, and postoperative bandaging. Preoperative preparation, mainly bowel preparation and perianal skin cleaning and disinfection. For surgical anesthesia, you can choose local infiltration anesthesia or hemianesthesia, and the surgical treatment will be performed only after successful anesthesia. The surgical procedure includes: preoperative exploration, stripping of external hemorrhoids, local suturing, and excision of hemorrhoidal nuclei. After the operation, the incision needs to be wrapped with a dressing, and if the skin edge of the local incision is uneven, it needs to be trimmed. After the operation, pay more attention to local cleanliness and hygiene, change the medicine regularly, and keep the bowel movement smooth. Appropriate use of antibiotic drugs anti-inflammatory, such as levofloxacin injection, cephalosporin antibiotics, etc., to prevent the occurrence of postoperative infection and regular follow-up review. If you have hemorrhoids, please consult the doctor in time and treat them actively, do not use medicine and cut privately, so as not to cause bleeding, infection and other dangers.
