Figure 6 Flowchart of the present study. One hundred eighty-eight patients met the eligibility criteria for degenerative lumbar spine stenosis and were assigned by random figure table to either the percutaneous transforaminal endoscopic decompression group or the fenestration group. Incision length, amount of intraoperative blood loss, length of procedure and hospitalization, and complication rates in the 2 groups were compared. In addition, computed tomography scanning and magnetic resonance imaging were performed. Finally, scores from a visual analog scale, the Japanese Orthopedic Association Score, and the Oswestry Disability Index were collected before and at 3, 6, and 12 months after the procedures. The modified Macnab criteria were applied to assess patient satisfaction at the last follow-up, 1 year after the procedures, and the data were analyzed to draw a conclusion.
