Vertebral column
Disc
The disc is a flexible structure located between the vertebrae, which acts as a cushion to absorb the impact caused by standing, sitting, and running, thereby protecting the vertebrae. Each disc is composed of two parts: the nucleus, which is situated at the center, and the annulus, which surrounds and encases the nucleus. If the annulus tears due to excessive pressure, it can lead to the protrusion of the disc’s nucleus, exerting pressure on the spinal nerves and causing pain in the lower back and legs. In severe cases, if left untreated, this condition may result in numbness, tingling, or even paralysis of the lower limbs.
Endoscope
An endoscope is a device that allows direct visualization of the vertebrae, surrounding tissues, and the disc without the need for an incision in the lower back. It can also be used to remove the portion of the disc that is exerting pressure on the nerve.
Advantages of Endoscopic Disc Surgery Compared to Traditional Surgery
In traditional surgery, a portion of the vertebral bone is necessarily removed to access the disc, whereas in endoscopy, no part of the bone is removed. In conventional surgery, the likelihood of postoperative adhesions around the spinal nerves is higher compared to endoscopy. During endoscopy, an 8-millimeter incision is made at a distance from the vertebra, whereas in traditional surgery, a larger incision is made in the lumbar region, which is also significant from an aesthetic perspective. Endoscopy is performed on an outpatient basis, eliminating the need for hospitalization in a clinic, and the patient can quickly return to their daily activities.
Necessary Preparations for Undergoing a Disc Endoscopy Procedure
Fasting before the procedure should be approximately 6 hours.
The presence of one companion is required for the patient’s administrative procedures.
Bringing all relevant medical documents related to the patient.
Intervention Clinics
The interventional clinics at pardis noor comprehensive imaging centers, utilizing advanced equipment and a specialized team, provide minimally invasive medical services with high precision and safety.
How Endoscopic Disc Surgery is Performed
Initially, the precise entry point for the endoscope is determined using CT scan or fluoroscopy. After administering anesthesia, an 8-millimeter incision is made.
In this region, the endoscope is inserted through the intervertebral foramen, and the portion of the disc exerting pressure on the nerve root is removed.
Potential Complications of Disc Endoscopy
The complications of endoscopy are very rare (4%), with the most common being tingling and pain in the intervertebral nerve area, which has been reported in only 5% to 15% of cases. This condition typically resolves on its own within a few weeks.
Disc herniation
In cases where the patient’s pain has not been sufficiently reduced after treatment, a repeat endoscopy may be necessary to remove any remaining disc fragments. However, this is required in only a small number of cases.

Frequently Asked Questions
What are the necessary conditions for performing a disc endoscopy?
Your new MRI, along with the results of your examination, will be reviewed by the clinic physician, and if you meet the necessary conditions, you will be able to proceed with the procedure.
Is hospitalization required after the procedure?
No, this procedure is typically performed on an outpatient basis, and the patient is discharged the same day. In most cases, hospitalization is not required unless there are specific circumstances where the physician deems it necessary.
What is the recovery and rest period like after endoscopic disc surgery?
After undergoing endoscopic disc surgery, it is recommended that the patient have relative rest at home for approximately one week. Following this period, daily activities can be gradually resumed, adhering to the physician’s advice. A full return to strenuous activities should only be undertaken based on the treating physician’s guidance.
