Abstract EN
Interbody fusion is a common surgical technique for diseases of the lumbar spine.
Biportal endoscopic-assisted lumbar interbody fusion (BE-LIF) is a novel minimally invasive technique that has a long learning curve, which can be a barrier for surgeons.
Therefore, we analyzed the learning curve in terms of operative time and evaluated the outcomes of BE-LIF.
A retrospective study of fifty-seven consecutive patients who underwent BE-LIF for degenerative lumbar disease by a single surgeon from January 2017 to December 2018 was performed.
Fifty patients underwent a single-level procedure, and 7 underwent surgery at two levels.
The mean follow-up period was 24 months (range, 14–38).
Total operative time, postoperative drainage volume, time to ambulation, and complications were analyzed.
Clinical outcome was measured using the Oswestry Disability Index (ODI), Visual Analog Scale (VAS) score for back and leg pain, and modified Macnab criteria.
The learning curve was evaluated by a nonparametric regression locally weighted scatterplot smoothing curve.
Cases before the stable point on the curve were designated as group A, and those after the stable point were designated group B.
Operative time decreased as the number of cases increased.
A stable point was noticed on the 400th day and the 34th case after the first BE-LIF was performed.
All cases showed improved ODI and VAS scores at the final follow-up.
Overall mean operative time was 171.74±35.1 min.
Mean operative time was significantly lower in group B (139.7±11.6 min) compared to group A (193.4±28.3 min).
Time to ambulation was significantly lower in group B compared to group A.
VAS and ODI scores did not differ between the two groups.
BE-LIF is an effective minimally invasive technique for lumbar degenerative disease.
In our case series, this technique required approximately 34 cases to reach an adequate performance level.
