Chemonucleolysis using chymopapain offers excellent or good long-term results for lumbar disc herniation in 90% of carefully selected patients. However, potential complications and risks must be carefully considered alongside its advantages over surgery.

Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Minimally Invasive Procedures

Background:

  • Lumbar disc herniation is a common cause of low back pain and sciatica.
  • Traditional surgical interventions carry risks such as epidural scarring and anatomical changes.
  • Chemonucleolysis offers a less invasive alternative for select patients.

Purpose of the Study:

  • To evaluate the long-term efficacy and safety of chemonucleolysis with chymopapain for lumbar disc herniation.
  • To assess the complication rates and patient outcomes following this procedure.

Main Methods:

  • A cohort of 60 patients with lumbar disc herniation underwent chemonucleolysis with chymopapain.
  • Patients were followed up for 1 to 3 years post-treatment.
  • Rigid selection criteria were applied, with only 18.6% of observed surgical lumbar disc cases treated.

Main Results:

  • Excellent long-term results were achieved in 50% of patients, with good results in 40%.
  • Fair and poor results were reported in 8.2% and 1.8% of patients, respectively.
  • Complications occurred in 27.2% of treated patients, including prolonged pain, stiffness, and sciatic pain.

Conclusions:

  • Chemonucleolysis with chymopapain demonstrates high efficacy for carefully selected patients with lumbar disc herniation.
  • The procedure avoids epidural scarring and permanent anatomical changes associated with surgery.
  • Potential complications, including the risk of paraplegia, necessitate careful patient selection and informed consent.
