Summary

This study aims to systematically evaluate the therapeutic efficacy of dual-channel endoscopic spinal decompression versus lumbar decompression with fusion for degenerative lumbar spondylolisthesis. Patients undergoing either procedure will undergo detailed preoperative and postoperative follow-up to compare outcomes between the two techniques, specifically assessing postoperative pain relief, neurological improvement, and the incidence of surgical complications.

Detailed description

1\) Screening and enrollment: This study is a prospective cohort study. Patients were screened based on inclusion and exclusion criteria. They were informed that surgical treatment for degenerative lumbar spondylolisthesis could involve either lumbar fusion surgery or dual-channel endoscopic decompression alone. Specific details of both procedures were explained, allowing patients to independently choose their surgical plan. Informed consent was obtained, and baseline data including symptoms, pain scores, and neurological function scores were collected. 2) Preoperative Assessment: All patients undergo detailed pain and neurological function evaluations prior to surgery. Pain intensity is quantified using the Visual Analogue Scale (VAS), while neurological function is assessed using systems such as the JOA score and ODI score. Imaging evaluations include MRI and CT scans. 3) Data Collection: Prospective data collection was conducted for both dual-channel endoscopic spinal decompression and lumbar decompression with fusion procedures. Surgical protocols were standardized, with documentation of operative images, procedure duration, blood loss, and intraoperative complications. Spinal vertebral and accessory tissue specimens were collected during surgery. 4) Postoperative Follow-up: Patients undergo follow-up at 1 month, 3 months, 6 months, 12 months, 24 months, and 36 months postoperatively. Repeat preoperative pain and neurological function assessments, conduct regular imaging reviews, and document postoperative recovery, complication rates, and recurrence. 5) Tissue Analysis: Specimens obtained during surgery undergo histological sectioning, RT-qPCR, or Western Blot testing to analyze differences. 6) Data Analysis: Statistical software analyzes collected data to evaluate changes in pre- and postoperative pain scores, neurological function scores, and imaging outcomes. Significance testing compares the efficacy and safety of the two surgical approaches.
