Endoscopic Discectomy

March, 2020 Minimally invasive treatments

Endoscopic Discectomy is a type of surgery in which a part of the patient’s intervertebral disc which is herniated into the canal is removed by endoscopy from the spinal canal.

Discectomy is usually used to treat intervertebral disc herniation.The elastic disk between the vertebrae acts like a bumper and suppresses severe blows to the spine. The intervertebral disc consists of two parts. A central part called the jelly-like nucleus pulposus and a distal ring-like part of the rigid ligament called the annulus fibrosis.

Endoscopic Discectomy

In the herniated disc, a portion of the annular portion weakens and tears, followed by the central gelatinous disc receding through the rupture and pressing on the spinal cord and nerve roots. To solve the problem, the patient must remove this gelatinous component that exits the nerve and put pressure on the nerves.

The process of removing the protruding appendage (which presses on the nerve) is called “endoscopic discectomy”. This technique is used to remove herniated disc from foraminal area.

Endoscopic Discectomy Technique:

Discs that are in the foraminal region or most of the protruding disc (extruded or extruded) tend to be foramen-prone and the foramen should not be too tight or have advanced osteoarthritis. The needle was first inserted into the foramen using a radiology machine (C-Arm) from the bottom of the pedicle, inserted through the dilator’s small incision, and then the endoscope was inserted into the desired disc site and after identifying the protruding segment. (Protrud or extruded) The part is removed and it is necessary to try to see Dura to remove the part that puts pressure on Dura.

Advantages of Endoscopic Discectomy:

  • Endoscopy does not require hospitalization and the patient is discharged on the same day.
  • The rate of adhesion in endoscopic lumbar disc surgery is lower than in open surgery.
  • In endoscopic discectomy, infection is less likely than open surgery because of continuous washing during surgery.
  • The incision in the endoscopic surgery is between 8 and 10 mm and in the endoscopiy treatment has caused no damage to the muscles around the vertebra.
