This is a question that my patients often ask me, and this article will provide a detailed answer to the question in the hope that it will help you. 1. How is minimally invasive surgery (PELD) for a herniated lumbar disc done? The most popular minimally invasive surgery for lumbar disc herniation is intervertebral foraminoscopy (also called PELD surgery). It is performed by placing a working channel through the intervertebral foramen or lamina space in the human lumbar spine to remove the disc that is compressing the nerves and causing the symptoms, thus relieving the patient’s symptoms. The incision is about 0.8 cm and is done under local anesthesia. The patient can usually get off the floor immediately after surgery, without the need for prolonged bed rest, and can be discharged from the hospital the same day or the next day after surgery. It can be said that the postoperative effect is good and the recovery is fast, which is a technology for the benefit of mankind. 2.What kind of patients are not suitable for minimally invasive surgery (PELD)? Patients with lumbar spinal slippage, patients with severe lumbar spinal stenosis, patients with cauda equina syndrome (such as urinary and fecal incontinence, urine and feces can not be discharged normally, young male penis can not be normal erection, no morning erection,), this situation is not suitable for minimally invasive surgery, the need for internal fixation surgery (stapling). In addition to the case mentioned in the appeal, simple lumbar disc herniation can be done with minimally invasive surgery. 3.Will minimally invasive surgery for lumbar disc herniation be painful intraoperatively? Minimally invasive surgery (PELD) for lumbar disc herniation is usually done under local anesthesia. We all know where the pain points of the whole operation are, so before the operation is performed, anesthetic has been administered to the area where pain will occur, so the patient will generally not experience pain during the operation. 4.Does minimally invasive surgery (PELD) for herniated lumbar discs recur after surgery? Minimally invasive surgery for herniated lumbar disc (PELD) is to remove the herniated nucleus pulposus to relieve nerve compression and relieve the patient’s symptoms. It does have the potential for recurrence, with some studies reporting a probability of about 15%. But whether recurrence after surgery, with the operation of the surgeon, whether the patient after surgery in accordance with medical advice recuperation has a lot to do with, if strictly in accordance with medical advice recuperation, the probability of recurrence will generally be very small, do not worry too much. 5.How should I recuperate after the minimally invasive surgery? In general, you should take more rest, avoid long-term bending, heavy lifting and heavy physical work, and ensure a good standing and sitting posture, and strengthen the exercise of the lumbar back muscles (please refer to my article “Neck and Lumbar Back Muscle Exercise (Cervical and Lumbar Spine Health Exercise, Original)”), which will minimize the probability of recurrence after minimally invasive surgery, and other healthy lumbar discs will not be easily protruded.
