Abstract

INTRODUCTION: Biportal endoscopic spine surgery (BESS) has gained traction for lumbar laminectomy and diskectomy. To justify the transition to BESS, outcomes and the surgical learning curve should be known. This study evaluates rates of complications with BESS and how these rates change with increased surgeon experience.

METHODS: A single surgeon's consecutive patients who underwent BESS were evaluated. Patients older than 18 years who underwent BESS for lumbar laminectomy and diskectomy were included. Patients with previous spine surgery, multiple levels, or BESS for fusion were excluded. Demographics, length of surgery, intraoperative complications, postoperative complications, and revision surgery were recorded. The learning phase group and mastery phase group were based on a cumulative summation analysis based on surgical time.

RESULTS: A total of 63 patients, with 31 and 32 patients in the learning and mastery group, respectively, were included. Surgical time decreased from 87 to 52 minutes in the mastery phase. Conversion to open decreased from 3 to 0 cases (P = 0.1803), intraoperative complications decreased from 3 to 0 (P = 0.1803), postoperative complications decreased from 7 to 2 (P = 0.017), and rates of revision surgery decreased from 4 to 1 (P = 0.4233).

CONCLUSION: This study suggests a learning curve of 31 cases for adequate performance of BESS for lumbar laminectomy and diskectomy.
