I worry about the technique of endoscopic intralaminar microdiscectomy as the visualization of the pathology is not very good and not all results are as good as a microdiscectomy. In addition, the statement “he will not remove the disc instead he only removes other tissues around (bone,ligamnet etc.) to decompress the nerve” sounds not appropriate. The protruding calcified disc is what is displacing the root. Not to remove this offending structure negates the procedure’s effectiveness. I think a microdiscectomy should give you the best benefit.
