Chemonucleolysis with chymopapain offers a safer, effective, and cheaper alternative to surgical discectomy for sciatica caused by herniated nucleus pulposus. This minimally invasive procedure is a time-tested treatment option for well-selected patients.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Procedures
  • Pain Management

Background:

  • Intractable sciatica due to herniated nucleus pulposus often necessitates surgical intervention.
  • Standard surgical discectomy carries risks and associated costs.
  • Percutaneous discectomy methods have varying degrees of efficacy and longevity.

Purpose of the Study:

  • To evaluate the efficacy and safety of chemonucleolysis with chymopapain for treating sciatica.
  • To compare chemonucleolysis with surgical discectomy and other percutaneous techniques.
  • To establish chemonucleolysis as a viable alternative to surgery.

Main Methods:

  • Chemonucleolysis involves the percutaneous injection of chymopapain enzyme to dissolve disc material.
  • Patient selection criteria are crucial for successful outcomes.

  • Procedure involves nucleolysis of the herniated disc.

    • Main Results:

    • Chemonucleolysis is safer, as effective, and more cost-effective than surgical discectomy when patients are well-selected.
    • It demonstrates greater effectiveness than percutaneous discectomy, particularly for non-contained discs.
    • Lumbar chymopapain nucleolysis is the only percutaneous method that has proven durable over time.

    Conclusions:

    • Chemonucleolysis with chymopapain is a well-established and effective treatment for sciatica.
    • It represents an attractive alternative to surgical discectomy for appropriate candidates.
    • Proper patient selection and procedural technique are paramount for optimal results.
