Hysterectomy includes three types of procedures: total hysterectomy, subtotal hysterectomy and extensive hysterectomy. Total hysterectomy and subtotal hysterectomy are medium-sized gynecologic procedures, while extensive hysterectomy is a major procedure. The most common clinical hysterectomy is total hysterectomy, in which the body and cervix of the uterus are removed, but not the parametrial and vaginal tissues, and is a medium-sized operation. This procedure is often used for benign uterine lesions, such as fibroids or benign endometrial lesions, where only the uterus is removed without affecting other organs, and the surgery is not very invasive. Secondary total hysterectomy is relatively small, removing only the body part of the uterus and preserving the cervix. The trauma and postoperative complications of this surgery are less than those of total hysterectomy, but the cervical part left behind may cause secondary cervical precancerous lesions or even cervical cancer, so subtotal hysterectomy is less clinically selected. Extensive hysterectomy is a major surgery and is used to treat malignant tumors such as cervical cancer. Not only uterine tissues are removed, but also part of the parametrial tissues, even including part of the nerves and upper vaginal tissues. This type of surgery is more invasive and increases the possibility of surgical complications, sometimes causing damage to the bladder, intestinal canal, and even the ureter. The large extent of the surgery also increases the risk of intraoperative hemorrhage, making it one of the more difficult major gynecological surgeries to perform. Any surgery has certain risks, and a minor surgery does not mean there is no risk, while a major surgery is not necessarily life-threatening, so be positive and optimistic about it. It is recommended to discuss the condition with the doctor, choose the appropriate operation and cooperate with the preoperative examination. And fasting fasting water before surgery, to ensure sufficient rest, to avoid tension and anxiety affect the surgery.
