Outcome after repeat lumbar microdiscectomy.
One of the standard treatments for herniation of lumbosacral disc material has become the microdiscectomy. Although multiple studies have assessed the outcome of microdiscectomy, only a few studies have evaluated the outcome of those patients who have undergone a second microdiscectomy at the same location as the original one. The purpose of this study was to review 55 patients who, over a 4-year period, underwent a second microdiscectomy at the same location as their original operation and to evaluate those factors associated with improved outcomes. The results showed the overall outcome to include 86% with complete or partial relief of all pain symptoms; 88% with complete or partial relief of sciatica; 85% with complete or partial relief of back pain; 100% returning to work in an average of 7 weeks; and 89% were glad they had the second operation. Those factors without predictive value included age, sex, weight, height, level of operation, side of operation, surgeon at the first or second operation (e.g. consultant or junior staff), length of the first operation ( < or = 60 min or > 60 min) and duration of symptoms before the first operation. The key features centred on preoperative job status, the interval between recurrence of symptoms and the second operation, and the duration of the second operation ( < or = 90 min).(ABSTRACT TRUNCATED AT 250 WORDS)
