Experience with chymopapain chemonucleolysis in 1,200 cases of lumbar disk disease indicates that it is an effective method of relieving pain resulting from an abnormal intervertebral disk. Complications were few; anaphylaxis occurring immediately after injection was by far the most serious. With the use of a corticosteroid and an antihistamine in preoperative preparation, the incidence of anaphylaxis had dropped, although it still occurs. On long-term follow-up, chemonucleolysis appears to be as good as laminectomy in properly selected cases.
