Complications After Anterior Lumbar Interbody Fusion in Patients with Prior Abdominal Surgery

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To investigate the association between postoperative complications after ALIF and prior abdominal surgery. SUMMARY OF BACKGROUND DATA: Anterior lumbar interbody fusion (ALIF) is a common spinal surgery associated with a variety of complications. Previous abdominal surgery is thought to influence the rate at which these postoperative complications occur. METHODS: Using PearlDiver, patients were identified who had undergone an ALIF from 2010 to 2024. Patients were separated based on surgical history (cesarean section, non-obstetric abdominal surgery, any abdominal surgery or no prior abdominal surgery). Complications were measured (30 d, 90 d, 1 y). Univariate and multivariate logistic regression were performed. Significance was set at P
