Keywords: transforaminal, interlaminar, endoscopic discectomy lumbar and transforaminal endoscopic; with last search date June 30, 2015. The selected articles were evaluated by two independent observers, using CONSORT statement for randomized clinical trials, and the scale of the Centre for Evidence-Based Medicine (EMBC) Oxford (1) to classify the evidence level and grade of recommendation.

Results: At the first search 31 articles were found, selecting 18 articles that fulfill the inclusion criteria (a randomized clinical trial, two cohort studies and 15 case series), finding an evidence level and grade of recommendation of 1b-A in an article, 2b-B in two articles and 4-C in 15 studies, respectively.

Conclusion: Most studies were classified as evidence level 4 with a grade C of recommendation, which indicates that transforaminal endoscopic discectomy for lumbar disc herniation treatment is a procedure with a favorable but not conclusive recommendation.
