In the past, if a patient with lumbar disc herniation wanted to be treated by surgery, the doctor would have to cut an 8 to 10 cm long incision in the patient’s back, and the hospitalization would take at least half a month before and after the surgery. Now, Xuanwu Hospital Functional Neurosurgery Department through the cavity technology, as long as in the lumbar disc herniation patients back to cut an 8 mm long incision, and then do the surgery under local anesthesia, 2 hours after the operation the patient can go home. Yesterday, more than 200 domestic and foreign experts who are attending the International Symposium on Endoscopic and Minimally Invasive Spine Technology in Beijing watched a live video broadcast of the surgery by spine surgeons from Germany and South Korea. Laparoscopic surgery for herniated discs is currently the most advanced international treatment technology. After accurately locating the disc through MRI imaging, the surgeon only needs to make an incision of 8 mm in diameter and use the endoscope to penetrate about 12 cm deep into the affected area to remove the herniated portion of the disc that is compressing the spinal cord and nerves, relieving the patient’s pain. The operation is performed under local anesthesia, and the doctor and patient can talk during the operation, which takes about 1 hour. Two hours after the surgery, the patient can move around and be discharged home. The advantages of laparoscopic surgery are less trauma to the patient, faster recovery, and lower total cost of treatment. Statistics show that about 80% of people will experience low back pain in their lifetime, which is mainly caused by herniated discs. Low back pain with radiating pain in the lower limbs is a typical manifestation of lumbar disc herniation, coughing, sneezing, straining to defecate and other actions can aggravate the pain, and some patients manifested urinary and faecal disorders, and in severe cases, loss of control of urination and defecation, or even paralysis and other symptoms.
