Abstract：【Objective】 To explore the application value of microscope and foraminoscope in transforaminal lumbar interbody fusion (TLIF) for patients with degenerative lumbar spinal stenosis (DLSS). 【Methods】 The clinical data of 82 DLSS patients admitted to our hospital from March 2021 to March 2023 were retrospectively analyzed. According to different surgical methods, they were divided into control group (TLIF under microscope) and observation group [TLIF under foraminoscope (E-TLIF)], with 41 cases in each group. Perioperative indicators, pain mediator levels, inflammatory stress levels, total incidence of postoperative complications, and lumbar function recovery were compared between the two groups. 【Results】 The incision length, operation time, and hospital stay in the observation group were shorter than those in the control group, and the blood loss was less than that in the control group (P<0.05). At 12 h, 24 h, and 48 h after surgery, the visual analogue scale (VAS) scores of the two groups were lower than those before surgery (P<0.05), and the observation group was lower than the control group (P<0.05). After surgery, the levels of substance P (SP), prostaglandin E2 (PGE2), neuropeptide Y (NPY), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), monocyte chemoattractant protein (MCP-1), and malondialdehyde (MDA) in both groups were higher than those before surgery, but the observation group was lower than the control group (P<0.05). There was no significant difference in the total incidence of complications between the two groups (P>0.05). At 6 months and 12 months after surgery, the Oswestry Disability Index (ODI) scores of the two groups were lower than those before surgery, and the Japanese Orthopedic Association (JOA) scores were higher than those before surgery (P<0.05), but there was no significant difference in ODI scores and JOA scores between the two groups at 6 months and 12 months after surgery (P>0.05). 【Conclusion】 Both E-TLIF and microscope-assisted TLIF can promote the recovery of lumbar function in DLSS patients, but E-TLIF can reduce operation time and blood loss, alleviate pain and inflammatory stress, and cause less trauma to the body.
