Daycase lumbar microdiscectomy surgery is not widely practised in the UK. We studied the outcome of microdiscectomy as daycase or inpatient surgery. Data collection was by retrospective case-note review of consecutive patients in each group. Inpatients not suitable for daycase surgery were excluded. There was no significant difference between patient groups in the rate of recurrent prolapse, wound infection, permanent sensory loss, or persistent postoperative pain. Symptoms resolved and patients returned to normal activities equally in both groups.
