Surgery, no matter how big or small, is a crucial battle for patients to overcome their illnesses. Since patients do not know much about their illnesses and surgeries, they always have millions of questions and concerns. Some patients even refuse to undergo surgery for fear of failure or poor results, which leads to aggravation of their condition. If these questions and concerns can be explained before the surgery, then the patient will be able to face the surgery with hope and confidence, and it will also help a lot in the recovery after the surgery. Take a look at the following conversation, does it relieve your concerns? Patient: How is the surgery anesthetized? Is it risky? DOCTOR: The risk of laminectomy is very low and most of the surgery is performed under local or split anesthesia. Local anesthesia pain sensation is very mild, while the pain sensation is completely eliminated during split anesthesia surgery. Since the dose of anesthetics used in this method is lower than that of painless delivery, the patient’s lower limbs can be moved during the surgery. Patient: How does the small incision ensure that blood vessels and nerves are not injured? Doctor: Many patients ask if there are instruments to monitor the operation, fearing that blind puncture will damage nerves and blood vessels. The puncture and surgery of intervertebral foramenoscopy are carried out under the fluoroscopic machine. The internal structure of the body is magnified by the camera during the surgery and displayed on the computer screen, and the blood vessels, nerves, muscles, bones, ligaments, etc., are all clearly seen, so it seldom causes unnecessary injuries; and if there is bleeding from capillaries, it can also be stopped by the radiofrequency cutter head of the intervertebral foramenoscopy, so as to avoid the surgical field from being covered by the blood. More direct monitoring is the patient’s “activity” during surgery. While the surgeon operates, the patient is asked to move his or her toes to see if the surgery has touched any nerves. If the surgery irritates a nerve, the patient will give feedback. If needed, a dye can be applied to the surgical site and the disc will be colored blue, while the nerve will not. This allows the surgeon to see more clearly and avoid blood vessels and nerves. PATIENT: Does the surgery remove the disc? Will the lumbar spine be unstable? Doctor: In many patients with lumbar disc herniation, the disc has herniated only 10-20%. The herniated nucleus pulposus (the gelatinous substance in the middle of the two vertebrae) is removed through intervertebral foramenoscopic surgery, and the nucleus pulposus and annulus fibrosus, which are free of lesions, are preserved. Generally, any intervertebral disc tissue that can be grasped off with a medullary forceps is diseased, while intervertebral discs that are not diseased cannot be grasped. The surgery does not empty out all the inter-discs, the good ones continue to support the lumbar spine, so it does not lead to lumbar instability. Patient: Is the surgery long? Will there be scarring after the surgery? How much does it cost? Doctor: The intervertebral foraminoscopy procedure usually takes 30 minutes to 60 minutes. From the time the patient is wheeled into the operating room to the time they come out (including anesthesia, locating the surgical site, etc.), it takes about one and a half hours to two hours. The surgical incision is only 6~8 millimeters, and only a very shallow mark can be seen after the operation; and because the lumbar spine lesion site is low, the scar can be covered with a belt after the operation. In order to meet the requirements of some beauty lovers, the surgical suture technique is also being improved, and intradermal suture can be done.
