Laser-assisted diskectomy performed by an internist resulting in cauda equina syndrome.

An internist performed percutaneous laser-assisted diskectomies (PLADs) on a patient with a sequestrated disc and stenosis. Subspecialists who perform PLADs should be trained in patient selection and lumbar diskectomy techniques. Chymopapain, percutaneous nucleotome-assisted diskectomy, and PLADs are alternatives to microdiskectomy for the management of lumbar disc herniations. PLADs were performed at the L4-5/L5-S1 levels in a 38-year-old woman with magnetic resonance (MR)-documented L4-5 stenosis and disc disease. After PLADs, she developed a subacute cauda equina syndrome. Two months later, a neurosurgeon performed an L4-5 coronal hemilaminectomy with diskectomy. Within 6 postoperative weeks, she was neurologically intact. Only specialists trained in the selection, neurodiagnostic, and surgical management of lumbar disc disease should perform PLADs.
