    PurposeOur team designed a novel two-medium compatible bichannel endoscopy system for spinal surgery, V-shape bichannel endoscopy (VBE) system. Hereby, this study will introduce minimally invasive transforaminal lumbar interbody fusion (TLIF) with VBE system and report its preliminary clinical results.MethodsFifty-two participants, who accepted VBE-assisted TLIF surgery (VBE-TLIF) in our hospital were included in this study. The duration of operation, off-bed time, and days of hospitalization were recorded. Besides, the patient's preoperative and postoperative pain were evaluated via visual analog scale (VAS), the functional status was evaluated via Oswestry dysfunction index (ODI) and modified MacNab criteria. Patients were asked to follow-up in the outpatient department at the 3rd, 6th, 12th, and 24th month after surgery. X-ray or CT was examined to evaluate the internal fixation position and interbody fusion result.ResultsAll patients received unilateral decompression with an average operation duration of 178.49 ± 27.49 min. After the surgery, their VAS score of leg pain and back pain reduced significantly. At the last follow-up, the VAS score of leg pain and back pain was 0.80 ± 0.69 and 0.86 ± 0.75 separately. The difference shows statistically significant with p < 0.05. At the last follow-up, the ODI was 15.20 ± 5.75. According to modified MacNab criteria, 39 patients rated their function as excellent, and 10 patients were good. The overall satisfaction rate reached 94%.ConclusionThe VBE system reported in the current study can complete TLIF surgery safely and effectively.© 2023.
