The objective of this study was to evaluate surgical outcomes of oblique lateral interbody fusion (OLIF) surgery in obese patients.
Medical records of geriatric patients who underwent OLIF for adult spinal deformity (ASD) from January 2017 to December 2018 were reviewed retrospectively. Obesity was defined as body mass index (BMI) was 25 or more. Surgical outcomes were compared between obese patients (BMI ≥25) with non‐obese patients (BMI <25).
Among total of 101 patients (31 males and 70 females) with a mean age of 69.8±9.6, 53 patients (52.5%) was classified to obesity group. Mean OLIF level (2.9±0.8 and 3.0±0.8, p=0.41) was not different between obese patients and non‐obese patients. Regarding surgical time, mean time of first stage operation (167.7±50.2 min vs. 160.7±47.9 min, p=0.48), and second stage operation (180.1±57.4min vs. 172.8±50.0min, p=0.50) showed no significant differen- ces between groups. Also, mean time for anterior retroperitoneal procedure was not different between groups (74.8± 21.2 vs. 72.6±20.7, p=0.59). The amount of surgical bleeding was also similar between groups. The incidence of postope- rative ileus (49.1% vs. 35.4%, p=0.23) and complication rates (32.7% vs. 20.8%, p=0.27) were not different between groups, either.
There showed no significant differences regarding operation time, surgical bleeding, and perioperative complications between obese patients and non‐obese patients who underwent OLIF for ASD.
