On July 20, 2015, Dr. Chuanli Zhou of the Eastern Spine Surgery Department successfully performed a percutaneous lateral approach lumbar discectomy using local anesthesia for a patient with a two-segment lumbar disc herniation. The successful implementation of this technique reflects the higher level of laminar foraminoscopic techniques in our department. The patient, a middle-aged male, had suffered from low back pain and numbness and pain in both lower limbs for 5 years. Fearing the risks of traditional open surgery and the high medical costs, he had been adhering to conservative treatment such as physiotherapy and acupuncture, but the effect was repeated and progressively aggravated, and he felt radioactive pain, numbness and weakness in both lower limbs when standing and walking, with the left lower limb being heavier. He sought the best treatment he could receive in the outpatient clinics of various hospitals on the island, but the answers he received were that he needed open fusion surgery, and finally came to our spine surgery department for treatment. Zhou Chuanli, the attending physician, believed that: 1, lumbar 4/5 and lumbar 5 sacral 1 double-segment disc herniation combined with lumbar 5 sacral 1 epiphyseal ring dissection, and lumbar 4/5 disc protrusion to the left, lumbar 5 sacral 1 disc protrusion to the right, no lumbar instability and spinal stenosis; 2, traditional open surgery can solve the patient’s current situation, but to perform two-segment fusion surgery at the same time, general anesthesia is required, the operation time is 3 hours, incision length is 10cm, bleeding is generally 500ml. 3.Minimally invasive surgery is the best solution for this patient. The biggest difficulty of this patient is the protrusion of discs in two segments, and the protrusion is in two directions, the lumbar 4/5 disc protrudes to the left and the lumbar 5 sacral 1 disc protrudes to the right, can the compression of both segments be solved simultaneously under local anesthesia? Can the compression of both segments be resolved simultaneously under local anesthesia? Can the patient tolerate prolonged surgery in prone position? The attending physician, Chuanli Zhou, repeatedly read the patient’s imaging data, extrapolated various puncture routes, predicted many possible difficulties and thought of countermeasures. Finally, it was decided to perform a multi-segment lumbar discectomy under local anesthesia with a percutaneous lateral approach laminectomy, which greatly improved the efficiency of the operation and reduced the amount of radiation with the help of the G-arm. The patient was discharged from the hospital on the second and third day and resumed daily physical work after one month. Intraoperatively, we found serious adhesions between the disc tissue and nerve roots, which was considered to be related to the patient’s long history and repeated physical therapy, and also suggested the importance of early treatment.
