Clinical Study on the Therapeutic Efficacy of Biportal Endoscopic Decompression Spine Surgery and Lumbar Decompression Fusion Surgery in the Treatment of Degenerative Lumbar Spondylolisthesis

December 4, 2025 updated by: The Fourth Affiliated Hospital of Zhejiang University School of Medicine
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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients with lumbar degenerative spondylolisthesis

Description

Inclusion Criteria:

  1. Aged between 50 and 90 years old with a confirmed diagnosis of degenerative lumbar spondylolisthesis;
  2. Clinical symptoms include chronic pain, nerve compression, or motor dysfunction, confirmed by imaging studies (e.g., MRI or CT);
  3. No significant improvement after at least 3 months of conservative treatment (e.g., medication, physical therapy), meeting surgical indications;
  4. Understand and consent to the relevant procedures of this study, and sign the informed consent form.

Exclusion Criteria:

  1. Patients exhibiting acute spinal cord compression symptoms or requiring urgent surgical intervention;
  2. Patients with a history of spinal surgery or conditions such as spinal deformities, severe osteoporosis, or active infections that may compromise surgical outcomes;
  3. Patients with severe comorbidities affecting assessment, such as cardiovascular disease, liver or kidney failure, or uncontrolled diabetes;
  4. Patients with psychiatric disorders or cognitive impairments preventing understanding or cooperation with the study process;
  5. Patients with allergies to anesthetics or surgical equipment that may increase intraoperative risks.

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
