Patient selection for chemonucleolysis with chymopapain is based on clinical symptoms, and CT scan is performed to exclude cases in which intradiscal therapy is contraindicated. Discography has been advocated during the intraoperative period, in order to detect contraindications for chemonucleolysis and communication between the discal space and the subarachnoid space. However, nowadays this no longer seems necessary in chemonucleolysis, for many reasons, including the following:
  1. 1)

    The interaction between contrast medium and chymopapain can result in inhibition of enzyme action [2, 3]

  2. 2)

    Moreover, in animal studies [5, 6] and as regards toxicity, there were more neurological complications as a result of the combination of contrast medium and chymopapain than with the solution alone injected into the subarachnoid space [7]

  3. 3)

    The interpretation of discograms may be hampered by unrecognized artifacts [4] and discography has no value in selection for discolysis [15, 16]
