The objective of this study was to compare surgical outcomes of oblique lateral interbody fusion(OLIF) surgery between patients who had a history of prior abdominal surgery or not. Methods: Medical records of patients who underwent OLIF for adult spinal deformity from January 2017 to December 2018 were reviewed retrospectively. Surgical outcomes were reviewed regarding operation time, surgical bleeding, and complications. Surgical time was divided and evaluated as first stage(posterior instrumentation and facet release/decompression), second stage(OLIF+posterior rod assembly), and OLIF only. Results: A total of 104 patients(31 males and 73 females) over 60 years old were selected with a mean age of 71.8± 9.5. Among them, 28 patients(26.9%) had received abdominal surgery previously. The surgical time of anterior retroperi- toneal approach was significantly longer in patients with prior abdominal surgery than patients without surgery(77.57± 17.65 min vs. 64.16±21.82 min, p=0.00). Estimated blood loss in second stage operation was significantly increased in patients with prior abdominal surgery compared to those without surgery(828.57±374.02mL vs. 653.29±261.70mL, p= 0.01). Postoperative ileus occurred more likely in patients with prior abdominal surgery, without statistical significance (53.6% vs. 36.8%, p=0.12). Perioperative complications were not different between two groups. Conclusion: History of prior abdominal surgery resulted in increased retroperitoneal approach time and surgical blood loss without increased risk of perioperative complications. OLIF could be performed safely in patients with prior abdominal surgery.
