Early result of percutaneous full-endoscopic transforaminal lumbar interbody fusion in the treatment of single-level lumbar degenerative diseases: a retrospective study.

ABSTRACT

OBJECTIVE: The study aimed to evaluate the short-term clinical efficacy of percutaneous full-endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) for lumbar degenerative diseases (LDD). METHODS: From July 2020 to July 2021, 93 patients who underwent single-level lumbar fusion procedure were retrospective analysis. The patients were divided into Endo-TLIF group and transforaminal lumbar interbody fusion (TLIF) group. General demographic and perioperative data were recorded, the clinical outcomes were evaluated using visual analogue scale (VAS) and oswestry disability index (ODI). The disk height (DH) was compared between the two groups. RESULTS: All of the surgical procedures were successfully completed, and the patients were followed for a minimum of 2 years. Intraoperative blood loss, drainage volume, time to independent ambulation and hospital length of stay in the Endo-TLIF group were significantly decreased in comparison with the open TLIF group (p < 0.05). The VAS for back pain on postoperative 7 day and ODI on postoperative 1 month were lower in the Endo-TLIF group than in the open TLIF group (P < 0.05), but no significant difference at 1 year and 2 years postoperatively (P > 0.05). The VAS score of leg pain had no demographic statistically significant differences between the groups (P > 0.05). The DH were significantly heightened after surgery compared to the preoperative height (p < 0.05). CONCLUSION: Endo-TLIF is a minimally invasive, safety surgery which can achieve comparable short-term effects as open TLIF. It may be a promising option for the treatment of LDD.
