Background Adhesive small bowel obstruction (aSBO) is a common surgical problem, with some advocating for a more aggressive operative approach to avoid recurrence. Contemporary outcomes in a real-world setting were examined. Study Design A retrospective cohort study was performed using the New York Statewide Planning and Research Cooperative database to identify adults admitted with aSBO, 2016-2020. Patients were stratified by the presence of inflammatory bowel disease (IBD) and cancer history. Diagnoses usually requiring resection were excluded. Patients were categorized into four groups: non-operative, adhesiolysis, resection, and ‘other’ procedures. In-hospital mortality, major complications, and odds of undergoing resection were compared. Results 58,976 patients were included. 50,000 (84.8%) underwent non-operative management. Adhesiolysis was the most common procedure performed (n = 4,990, 8.46%), followed by resection (n = 3,078, 5.22%). In-hospital mortality in the lysis and resection groups was 2.2% and 5.9% respectively. Non-IBD patients undergoing operation on the day of admission required intestinal resection 29.9% of the time. Adjusted odds of resection were highest for those with a prior aSBO episode (OR 1.29 95%CI 1.11-1.49), delay to operation ≥3 days (OR1.78 95%CI 1.58-1.99), and non-New York City (NYC) residents being treated at NYC hospitals (OR1.57 95%CI 1.19-2.07). Conclusion Adhesiolysis is currently the most common surgery for aSBO, however nearly one-third of patients will undergo a more extensive procedure, with an increased risk of mortality. Innovative therapies are needed to reduce the risk of resection.
