The whole process of hemorrhoidectomy includes preoperative routine physical examination, surgical anesthesia, formal surgery and postoperative care.
1. Pre-operative routine physical examination: clean enema, skin preparation, and clarification of the extent of hemorrhoidal lesions, which can help the doctor to rule out contraindications to surgery, so as to clarify the specific surgical plan.
2. Surgical anesthesia: it can be local anesthesia or sacral anesthesia, most of this anesthesia will not affect the normal diet, conscious and painless during surgery.
3. Formal surgery: the patient takes the truncated position, local disinfection and laying aseptic cavity towel, with the instrument to dilate the anus after the start of the operation. The main surgical method is the traditional endotomy, hemorrhoids above the dentate line will be cut out locally with an electric knife to stop bleeding, and hemorrhoids below the dentate line need to be free to the root and then ligated.
4. Post-operative care: anti-infection treatment and daily cleaning and dressing change are required until the postoperative wound heals.
The above is the basic process of hemorrhoidectomy.
