Incidence and Risk Factors of Postoperative Ileus in Oblique Lumbar Interbody Fusion Surgery: A Retrospective Study

This study demonstrated that frailty and nutritional status can influence the occurrence of POI after OLIF. Additionally, bowel manipulation associated with the location of psoas muscle and vertebral body was identified as a risk factor. Proper assessment and improvement in patient frailty and nutritional status before surgery can help predict and prevent the occurrence of postoperative POI.
