Introduction: Unilateral laminectomy for bilateral decompression (ULBD) by single approach has become relevant in patients with multilevel stenosis. When it is performed at more than one level with a single approach, alternately and crosswise to the previous approach, it is known as a “slalom” technique.The objective of this article is to present a series of cases treated with the slalom technique with simultaneous bilateral endoscopic and microscopic assistance in patients with multilevel lumbar canal stenosis. Materials and Methods: Retrospective analysis of patients treated simultaneously from January 2017 to January 2018, all operated by the same surgical team with tubular separators and simultaneous endoscopic and microscopic assistance. Results: Four patients, all male, with an average age of 73.5 years with multilevel lumbar pathology, were included. In total, 10 segments were decompressed (2.5 levels per patient, on average), with an average surgical time of 107 minutes. There were no associated complications, the patients were discharged within the day of surgery. Conclusions: The minimally invasive Slalom technique is a very effective procedure to resolve symptoms of multilevel stenosis associated with a bilateral combined technique with two surgical teams, resulting in a viable option for the treatment of this type of patient.
