Abstract

Objective　To introduce and discuss surgical highlights and advantages of BELIF (Biportal Endoscopic Lumbar Intervertebral Fusion), its short-term clinical therapeutic efficacy and potential surgical complications.　Methods　BELIF surgery was performed on 54 patients (Male: 24 cases, female: 30 cases, age: 38~79 years old) and they were followed-up at least 3 months. The VAS and ODI scores were recorded before and afer surgery. The total operation time and microscopic operation time，the perioperative complications of the patients and the perioperative bleeding volume were recorded and calculated. The percentage of bone graft area in the total intervertebral disc area was measured. Results The VAS score of low back pain improved from (6.13±0.64) before operation to (2.21±1.04) the last follow-up (P<0.05). The ODI score improved from (46.54±13.75) before operation to (14.78±9.23) (P<0.05). The average operation time was 164 min and the average endoscopic time was 102 min. The average bleeding volume was (156±31) ml. The average area of bone graft was (48.5±9.4)%. There was no serious complications. Conclusions BELIF is a minimally invasive, safe and efficient lumbar fusion surgery with good short-term clinical effect and few complications.
