Purpose This study aims to evaluate the efficacy and safety of the full-endoscopic lumbar discectomy (FELD) via lateral superior articular process (LSAP) approach and full-endoscopic transforaminal discectomy (FETD) for treating far lateral lumbar disk herniation (FFLDH). Methods From January 2020 to June 2022, patients who were diagnosed as FLLDH underwent the FELD via LSAP approach or FETD. The operation time, estimated blood loss, length of hospital stays, and complications were recorded. The visual analog scale (VAS) for back pain, VAS for leg pain, and the Oswestry Disability Index (ODI) scores was measured during preoperative and postoperative follow-up. Results Thirty-two patients were enrolled in this study, of which 12 patients were treated with the FELD via LSAP approach (LSAP-FELD group) and 20 patients underwent FETD (FETD group). The LSAP-FELD group exhibited significantly shorter operation times and hospital stays compared to the FETD group, while no statistically significant differences were observed in intraoperative blood loss and complication rates. There were no significant differences in the VAS for back pain, the VAS for leg pain, and the ODI score between the two groups preoperatively and three days, three months, and the last follow-up postoperatively. Conclusions Both the FELD via LSAP approach and FETD have demonstrated favourable clinical efficacy in the treatment of FLLDH. Notably, the FELD via LSAP approach shows the advantages of shorter operation time and hospital stays.
