Hysteroscopic surgery refers to minimally invasive surgery performed with a hysteroscope, which allows direct observation of abnormal lesions in the uterine cavity and is a common tool in the treatment of gynecological diseases. Hysteroscopic surgery is divided into two types of surgery: examination surgery and treatment surgery, which are different and have different pain conditions and cannot be generalized.1. Examination surgery: If a woman suspects endometrial lesions, abnormal uterine bleeding, uterine adhesions, endometrial thickening and other diseases, she can undergo hysteroscopic examination. If necessary, scrape the uterine cavity tissues for pathological testing to clarify the nature of the lesion. During the operation, as the cervix needs to be dilated, patients may have slight pain and abdominal distension symptoms, and some will have contraction pain, but the pain is generally not serious, similar to the degree of ordinary menstrual cramps, and most patients can tolerate it. 2. Therapeutic surgery: For patients diagnosed with endometrial polyps and submucosal fibroids of the uterus, hysteroscopic surgery is performed. Anesthesia is required for the surgical operation. Generally, lumbar anesthesia or combined block anesthesia will be chosen, and there will be no painful performance during the operation. Without anesthesia, the stimulation of the operation can cause severe pain to the patient, which in turn increases the risk of the operation. In addition, after the hysteroscopic surgery, you need to observe whether there is any bleeding from the vagina, and if there is a large amount of fresh blood flow, you need to deal with it immediately. You can resume eating after the operation, starting with warm water, and if there is no discomfort, you can gradually transition to a liquid diet, such as millet porridge, and return to a normal diet every other day.
