In case of nerve injury, the relevant muscle group may not work and the patient may have difficulty walking without support. As with any surgical treatment, infection may also occur. After endoscopic surgery (fully closed lumbar hernia surgery), infection is almost non-existent. Adhesions (epidural fibrosis) can be seen in the surgical area in the long term (1 year) after open surgery and microdiscectomy and can cause serious pain. In this difficult-to-treat condition, interventional pain procedures, re-surgeries and screw applications may be required. Endoscopic (with fully closed technique) adhesions are almost never seen. One of the most common reasons for failure after hernia surgery is the recurrence of hernia. Hernia recurs in 5-10% of patients. Although it is usually seen in the first 3 months, it can also be seen years later. Although the patient's weight, work, muscle structure and especially the type of hernia are important, the hernia may recur without any risk factors. In some of the recurrent hernias, repeat surgery may be required.
