Fully Endoscopic Interlaminar and Transforaminal Lumbar Discectomy: Short-Term Clinical Results of 163 Surgically Treated Patients

ObjectiveTo evaluate the clinical outcomes of patients with lumbar disc disease undergoing fully endoscopic surgery at a single clinic.MethodsBetween August 2009 and January 2012, 163 patients (74 men and 89 women) underwent fully endoscopic lumbar discectomy. All patients were followed for 1 year after surgery. The Oswestry Disability Index and a visual analog scale were used to analyze outcomes.ResultsDuring the follow-up period, 114 (70%) patients had no complaints, 30 (18%) patients had occasional pain, and 19 (12%) patients had no improvement. During postoperative follow-up, 8 patients required repeat surgery for recurrence or residual fragments. Postoperatively, 4 patients experienced dysesthesia, which completely resolved in time. Neurologic deterioration occurred in 5 patients, 4 of whom recovered completely without any intervention. Dural tears occurred in 6 patients.ConclusionsFully endoscopic interlaminar or transforaminal surgeries are safe and effective treatment modalities for lumbar disc herniations. Despite the difficulties of acquiring this new technique, good results can be achieved with sufficient experience.
