Laparoscopic disk herniation:

Laparoscopic disk herniation:

For patients with severe stage disc herniation, which can not be treated with high frequency waves, physicians may apply a laparoscopic method to remove the disc.

“The special thing of this colonoscopy is that soon after the surgery, both the physician and the BV can go out for pho,” said Dr. Thach.

A herniated disc herniation causes the person to be very painful on one leg, or both on both legs, where the patient may not be able to walk. Sometimes after a strong impact such as sneezing, coughing hard patients hard can not go anymore. Previously for the treatment of open surgery, a general anesthetic or local anesthetic, when the doctor intervenes, touches the nerves of both doctors and patients do not know. Only after the surgery, patients with hemorrhage paralysis to know the operation to leave sequelae. Especially with open surgery will destroy the entire structure of the spine, skeletal muscle so the spine is affected, relapses quickly.

In addition to laparoscopic surgery, the patient is given local anesthetic and complete local anesthesia to have complete control over the operation. Just touch the nerve, the pain will tell the doctor immediately should reduce the risk of complications.

Since 2008 Viet Duc Hospital has performed about 500 laparoscopic surgery and showed many outstanding advantages. The patient is completely controlled, has control of the operation, after the operation, the length of hospital stay is short, limited complications (without bleeding) due to a small incision 1 cm with hot tub with finger, numb at Place, keep it in place of the hernia. As a result, the spinal structure is not affected, thus destroying the possibility of recurrence.

Get a little invasive hernia:

Getting a little invasive hernia is also a progressive surgical approach in the world. By replacing the open-eye operation with a new one with a light bulb (1.5 cm in diameter), it is easy for the tube to be placed in the hernia to retrieve the hernia. This method is applicable to patients who can not intercede with laparoscopy. The use of this method is similar to endoscopy because through the tube diameter is small, so the structure of the spine is less damaged, less damaged so it does not affect the spine.

Replacement of the spinal prosthesis:

Previously, in patients with late-onset spinal disc herniation, the intervention was discontinued by discarding the damaged disc and replaced with a disc (or fragment) Hardened, welded two vertebrae together. Thus, the movement of the patient is limited and there is a danger of damaging the adjacent discs more quickly.

But with the method of disc replacement, the patient can still perform the usual flexible movements such as with normal disc. After replacing the artificial disks, the patient can still bend, swivel, turn left, lean right. This method was first implemented in Vietnam in 2009 by the doctors Viet Duc hospital. So far, this technique has successfully applied to hundreds of patients.
