Our Summary

This study compares two minimally invasive surgical techniques used to treat lumbar spinal stenosis: microendoscopic discectomy (MED) and unilateral biportal endoscopic discectomy (UBED). To do this, researchers looked at multiple databases and selected ten studies that included a total of 1,514 patients.

The results showed no significant differences between the two techniques in terms of operation time, blood loss, complications, and disability index score. However, patients who underwent UBED reported less back and leg pain and had shorter hospital stays than those who underwent MED. These differences were only observed in the short term (3 to 6 months) after the operation.

This means that while UBED may provide some short-term benefits over MED, both techniques are equally effective and safe in the long term. Therefore, either technique can be used in clinical practice based on the patient’s specific needs and circumstances.

Doctor’s Tip

A helpful tip a doctor might tell a patient about discectomy is to follow post-operative care instructions closely, including proper wound care, physical therapy exercises, pain management, and restrictions on activity. This can help ensure a successful recovery and reduce the risk of complications. It is also important to attend follow-up appointments with your healthcare provider to monitor your progress and address any concerns.

Suitable For

Patients who are typically recommended for discectomy are those who have lumbar spinal stenosis, herniated discs, or other conditions causing nerve compression in the lumbar spine. These patients may experience symptoms such as back pain, leg pain, numbness, tingling, and weakness in the legs. Patients who have not responded to conservative treatments such as physical therapy, medications, and injections may be considered for discectomy surgery. Additionally, patients who have significant functional limitations and quality of life issues due to their symptoms may also be candidates for discectomy.

Timeline

Before the discectomy procedure, the patient typically experiences symptoms of lumbar spinal stenosis, such as back pain, leg pain, numbness, and weakness. They may have tried conservative treatments such as physical therapy, medications, and injections with limited success.

After the discectomy, the patient may experience immediate relief from their symptoms as the pressure on the nerves is relieved. They may also experience some post-operative pain and discomfort, which can be managed with pain medications. Over time, as the surgical site heals, the patient’s symptoms should continue to improve, and they may gradually return to their normal activities and daily routine.

Long-term outcomes of discectomy surgery are generally positive, with most patients experiencing significant improvement in their symptoms and quality of life. However, it is important for patients to follow their surgeon’s post-operative instructions, attend follow-up appointments, and engage in rehabilitation exercises to optimize their recovery and prevent future issues.
