Objective: The purpose of this study was to analyze if celiac disease (CD) is associated with increased postoperative complications following single-level posterior lumbar fusion (PLF).
Methods: A retrospective database review was performed using the PearlDiver dataset. The study population included all patients older than 18 years who underwent elective PLF with diagnosis of CD using International Classification of Diseases (ICD) and Current Procedural Terminology (CPT) codes. Study patients were compared with controls for 90-day medical complications and 2-year surgical complications including 5-year reoperation rates. A multivariate logistic regression was used to determine the independent effect of CD on the postoperative outcomes.
Results: A total of 909 patients with CD and 4483 patients in the matched control group who underwent primary single-level PLF were included in this study. CD patients had a significantly increased risk of 90-day emergency department (ED) visit (OR 1.28; P = 0.020). CD patients also demonstrated higher rates of 2-year pseudarthrosis and instrument failure, but they were statistically comparable (P > 0.05). There was no difference in 5-year reoperation rate. There were also no significant differences in 90-day medical complication rate and 2-year surgical complication rate between the two groups. In addition, there were no differences in procedure cost and 90-day cost.
Conclusions: For CD patients undergoing PLF, the current study demonstrated increased rate of 90-day ED visit. Our findings may be useful for patient counseling and surgical planning for those with this condition.
