Comparison of Preliminary clinical outcomes between percutaneous endoscopic and minimally invasive transforaminal lumbar interbody fusion for lumbar degenerative diseases in a tertiary hospital: Is percutaneous endoscopic procedure superior to MIS-TLIF? A prospective cohort study

The study indicated that PETLIF had advantages of less surgical trauma, less postoperative low-back pain, less hidden blood loss, and faster recovery, compared with MIS-TLIF. There was no significant difference in medium-short term surgical outcomes between the 2 techniques. However, the indications of PETLIF is relatively limited, and the learning curve of PETLIF is deep, surgeons need to select indications strictly. Further study with big sample size and long-term follow-up is needed.
