Area of Science:

  • Neurosurgery
  • Pharmacology
  • Biochemistry

Background:

  • Chymopapain has a long history of use for herniated nucleus pulposus.
  • Despite past controversies and complications, it has shown sustained clinical success over three decades.

Purpose of the Study:

  • To evaluate the long-term safety and efficacy of chymopapain in treating herniated nucleus pulposus.
  • To compare the outcomes and complications of chemonucleolysis with laminectomy.

Main Methods:

  • Review of adverse events reported to the FDA between 1982-1991 (121 events in 135,000 patients).
  • Analysis of long-term patient outcomes following chemonucleolysis versus laminectomy.
  • Comparison of complication rates and mortality between the two procedures.

Main Results:

  • The overall mortality rate was 0.019%.
  • Complication incidence was lower than with laminectomy.
  • Chemonucleolysis demonstrated maintained long-term improvement, unlike laminectomy outcomes which tend to deteriorate.
  • Chemonucleolysis offers cost savings primarily due to shorter hospitalizations.

Conclusions:

  • Chymopapain remains a safe and effective treatment for herniated nucleus pulposus when indications, contraindications, and technique are meticulously followed.
  • Chemonucleolysis presents a favorable alternative to laminectomy with better long-term results and cost-effectiveness.
  • Ongoing research and development, including protocols for cervical application, suggest continued relevance and potential for chymopapain.
