About this study

Official title: US-MR Image Fusion-guided Versus Fluoroscopy-guided Percutaneous Transforaminal Endoscopic Discectomy for the Treatment of Lumbar Disc Herniation: a Comparative Cohort Study

The purpose of this study is to evaluate the feasibility and efficacy of US-MR image fusion-guided percutaneous transforaminal endoscopic discectomy for the treatment of lumbar disc herniation

Read the detailed description

Lumbar disc herniation (LDH) is a common pathological process leading to spinal surgery. Open discectomy used to be a widespread procedure for surgical treatment for symptomatic LDH. Currently, with rapid progress of endoscopic techniques, several minimal invasive endoscopic surgeries have been developed to perform discectomy. Percutaneous transforaminal endoscopic discectomy (PTED) a widely used minimal invasive surgical procedures, the effectiveness of which has been proved to be comparable to conventional open discectomy. However, the use of fluoroscopy may be usually required to indirectly visualize pertinent anatomy to achieve an optimal result on radiographs. As we known, increased radiation exposure may be associated with potential stochastic and deterministic adverse events. Therefore, it is important to reduce the radiation dose of practitioners to minimize risk of potential radiation-induced complications.

Ultrasound-MR fusion technique combines the advantages of ultrasound and MR, and overcome the shortcomings of each single imaging method. It provides MR cross-sectional multiplanar images that correspond to the acquired real-time US images, and all images can be displayed simultaneously and in real time according to the angle of the US transducer. US-MR fusion image has been widely used in prostate and liver intervention. However, to our limited knowledge, there is only one research about the application of US-MR fusion image in lumbar spinal surgery.

In this study, a comparative cohort study will be performed to evaluate feasibility and efficacy of US-MR image fusion-guided percutaneous transforaminal endoscopic discectomy for the treatment of lumbar disc herniation(LDH). We will conduct the study at the 3rd affiliated hospitals of Sun Yat-Sen University.

Two groups of patients will be investigated: patients diagnosed with lumbar disc herniation undergoing US-MR image fusion-guided PTED (US-MR PTED), and fluoroscopy-guided PTED (FL PTED).

The primary outcomes of the study will be radiation exposure and puncture time. Secondary outcomes include fusion efficacy, puncture accuracy, puncture satisfaction of surgeon, comfort of patient and clinical effectiveness.

On the basis of the results of this trial we will, for the first time, have scientific evidence as to the feasibility and efficacy of US-MR image fusion-guided percutaneous transforaminal endoscopic discectomy for the treatment of lumbar disc herniation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. radiation exposure

    dose of radiation exposure

    Measured: during operation

Secondary outcomes (6)
  1. puncture accuracy

    the accuracy of puncture position confirmed by fluoroscopy.

    Measured: during operation

  2. puncture satisfaction of surgeon

    use Visual Analog Scales (VAS,scores ranging from 0 to 10, with higher scores indicating more satisfactory) to evaluate the satisfaction of surgeon during puncture

    Measured: during operation

  3. comfort of patient

    use Visual Analog Scales (VAS,scores ranging from 0 to 10, with higher scores indicating more comfortable) to evaluate the comfort of patient during puncture

    Measured: during operation

  4. degree of pain

    Visual Analog Scales (VAS, scores ranging from 0 to 10, with higher scores indicating more severe pain)

    Measured: preoperation, immediately postoperation, 1 week postoperation

  5. degree of disability

    Oswestry Disability Index (ODI) score (ranging from 0 to 100, with higher scores indicating more disability related to pain)

    Measured: preoperation, immediately postoperation, 1 week postoperation

  6. puncture time

    the time from the begin of puncture to the confirmation of optimal puncture

    Measured: during operation

Questions about this trial

What is this clinical trial studying?

A study testing US-MR image fusion-guided PTED and fluoroscopy-guided PTED in people with Lumbar Herniated Disc, run by Third Affiliated Hospital, Sun Yat-Sen University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
