”small stomach pain, menstrual period is more serious, usually slightly better, with several months of anti-inflammatory drugs, Chinese medicine, a variety of physical therapy with, but repeatedly can not be better, as soon as the work is tired, small stomach pain will aggravate, even married life is also affected”, Ms. Tian complained that her lower abdominal pain has been for more than half a year, but also The gynecology department of various hospitals repeatedly, various tests did not find anything wrong, repeatedly using anti-inflammatory drugs and Chinese medicine, spending tens of thousands of dollars, although the condition did not progress, but also did not see improvement, work was also affected. After careful examination, the treating doctor Yang Xiaomin ruled out organic diseases and gave regular and sufficient anti-inflammatory treatment for one week, and then diagnosed her with “chronic pelvic pain”. After obtaining the patient’s informed consent, Dr. Yang performed a new technique of chronic pelvic pain treatment —- “CT-guided infra-abdominal plexus block”: under the precise guidance of CT, a fine needle was injected into the vicinity of the infra-abdominal plexus, which is in charge of the lower abdomen and pelvis, and 5 ml of anhydrous alcohol was injected into the patient, who immediately felt the pain disappear. Disappeared, after several days of observation still without any discomfort and pain recurrence, happily discharged from the hospital, said with emotion when discharged, “I did not expect that the small stomach pain for so long, see so many hospitals can not see, in Jiaxing a hospital just a shot on the cure.” Dr. Yang said that chronic pelvic pain refers to pelvic pain that is non-cyclical, lasts for more than 3 months, and is ineffective for non-opioid or anti-inflammatory analgesic treatment, and is one of the most common symptoms in middle-aged women. It is mainly caused by common gynecological diseases such as chronic pelvic inflammatory disease, endometriosis, adenomyosis, etc. It is mainly manifested by recurrent and gradually increasing pain in the small stomach, which seriously affects the quality of life of patients. The combination of anti-inflammatory and analgesic drugs, organ-specific drugs, progesterone and antidepressants has some effect, but the efficacy is not exact. For those with organic lesions, laparoscopic surgery is often required to remove the visible lesions or remove the uterus and other organs in the pelvis to effectively solve the problem; for those without organic lesions, surgery is required to remove the inferior epigastric plexus in charge of the lower abdomen and pelvis to achieve better results. However, it is difficult to be accepted by patients because of the large trauma of surgery. Therefore, a large percentage of these women have to choose the “get over it” method to deal with this annoying disease. Dr. Yang also introduced that our gynecology department has recently cooperated with the pain department to carry out a new technique of CT-guided inferior epigastric plexus block for chronic pelvic pain: this technique is to give anhydrous alcohol to the inferior epigastric plexus by puncture under the precise guidance of CT, and to achieve effective analgesia by suppressing the function of this visceral nerve for a long time, which can effectively treat visceral pain without affecting other sensory and motor nerves. In addition, only a thin needle needs to be stuck in the back, and you can get out of bed after removing the needle, which is almost non-invasive and avoids open surgery. From the results of patients treated so far, this technique is effective and minimally invasive, and is a more ideal choice for treating chronic pelvic pain.
