The goal of this randomized clinical trial is to investigate whether modified enhanced recovery after surgery (ERAS) in oblique lumbar interbody fusion (OLIF) can shorten the postoperative hospital stay among patients with lumbar degenerative disease. The main questions it aims to answer are: Whether ERAS can shorten the postoperative hospital stay. Whether modified ERAS can improve postoperative functional recovery, improve functional score and pain score, reduce hospitalization costs, improve mental state, and improve abdominal indicators, etc. Participants will be randomized into modified ERAS group, or control group.
