ObjectiveWe compared the demographics, risk factors, and complications for adult patients with recurrent lumbar disc herniation (RLDH) undergoing revision discectomy with or without concurrent fusion.MethodsThe American College of Surgeons National Surgical Quality Improvement Program database was used to identify patients who had undergone revision discectomy with or without simultaneous fusion. The demographic variables and various peri- and postoperative complications were compared between these 2 patient groups.ResultsA total of 6901 discectomy patients were included in the present study, of whom 2996 (43.4%) had undergone revision discectomy with fusion and 3905 (56.6%) had undergone revision discectomy alone. The revision discectomy with fusion group was significantly more likely to be older, female, and White or Black and to have a higher average body mass index than was the revision discectomy alone group. The discectomy with fusion group had longer hospital lengths of stay and was more likely to have a diagnosis of hypertension, insulin-dependent and non-insulin-dependent diabetes, and chronic obstructive pulmonary disease. In addition, the patients who had undergone discectomy with fusion were significantly more likely to develop pneumonia, require ventilation for >48 hours, require a blood transfusion, and to develop urinary tract infection, myocardial infarction, deep vein thrombosis, or pulmonary embolism compared with the patients who had undergone revision discectomy only.ConclusionsOur findings reveal that older patients with more comorbidities were more likely to undergo revision discectomy with fusion. Also, this surgical group experienced more adverse events after their procedure compared with the revision discectomy only group.Published by Elsevier Inc.
