The First Affiliated Hospital of PLA General Hospital successfully removed the herniated disc nucleus pulposus that had been tormenting a 32-year-old male patient for more than a year by using microendoscopic disc nucleus pulposus removal in the posterior lumbar spine. The patient was an employee of a real estate company in Beijing. In May last year, he suddenly developed back pain without any obvious cause, and a CT examination suggested a lumbar disc herniation, and surgery was recommended. In early March, the patient went to the First Affiliated Hospital of the PLA General Hospital for treatment, fearing that he would be fired from the company and lose his job, and fearing surgery. The patient was found to be walking with bent hips and a limp gait, with reduced muscle strength of the left lower limb, dorsal foot and long toe flexors, and impaired dorsiflexion and plantarflexion of the left toe, and MRI suggested lumbar lordosis and disc herniation. Wu Wenwen, director of orthopedics, and Shang Weilin, deputy director of orthopedics, organized several expert consultations and decided to treat the patient with microendoscopic disc nucleus pulposus removal via a posterior lumbar approach according to his condition and his request. On March 3, in close cooperation with the Department of Anesthesiology, Dr. Li Zhenzhou, deputy chief physician, performed microscopic endoscopic disc nucleus pulposus removal in the posterior lumbar approach. First, a microscopic incision of about 1.6 cm in length was made in the posterior lumbar region of the patient, and a 1.6 cm diameter tubular surgical channel was established under the precise guidance of the C-shaped arm. To prevent injury to the peripheral nerves, the diseased disc tissue was stained dark blue with melanoma under endoscopic surveillance to make it clearly distinguishable from the peripheral nerve tissue, and then the herniated disc nucleus pulposus was removed with a nucleus pulposus forceps. The whole operation took only one hour, and the patient felt the disappearance of back and leg pain immediately after the operation. Li Zhenzhou said that microscopic endoscopic disc nucleus pulposus removal is the latest minimally invasive surgical method developed abroad in recent years for the treatment of lumbar disc herniation. Compared with traditional open surgery, the incision is small, there is almost no bleeding, no scarring, quick recovery and low recurrence rate. Since the operative field can be magnified 10-40 times under the surveillance of endoscope, it is easy to operate and can effectively avoid nerve root injury and preserve the stability of lumbar spine.
