Chemonucleolysis and automated percutaneous discectomy--a prospective randomized comparison.

Area of Science:

• Neurosurgery
• Minimally Invasive Spine Procedures
• Pain Management

Background:

• Disc herniations are a common cause of back and leg pain.
• Surgical interventions aim to alleviate pain and neurological deficits.
• Chemonucleolysis (CN) and automated percutaneous discectomy (APD) are minimally invasive options.

Purpose of the Study:

• To compare the efficacy of chemonucleolysis (CN) versus automated percutaneous discectomy (APD) for painful disc herniations.
• To evaluate short-term and long-term outcomes, including pain scores and neurological deficits.
• To assess complication rates and the need for revision surgery.

Main Methods:

• Prospective randomized study of 22 patients with painful disc herniations.
• Patients were randomized to either chemonucleolysis (CN) or automated percutaneous discectomy (APD).
• Outcomes assessed included Oswestry score, back pain, leg pain, and neurological deficits at 2-year follow-up.

Main Results:

• Both CN and APD groups showed significant improvement in neurological deficits and Oswestry scores.
• One intra-operative complication occurred in the APD group.
• At 2 years, CN patients demonstrated significantly better Oswestry scores and reduced recurrence of back and leg pain compared to APD patients.

Conclusions:

• Chemonucleolysis (CN) is a safe and effective treatment for painful disc herniations.
• CN provides superior long-term pain relief and lower recurrence rates compared to automated percutaneous discectomy (APD).
• Further research may explore patient selection criteria for optimal outcomes with each procedure.
