Outcomes in Adhesive Small Bowel Obstruction from a Large Statewide Database: What to Expect after Non-Operative Management

Background Although adhesive small bowel obstruction (ASBO) is frequently managed non-operatively, little is known regarding outcomes on readmission following this approach. Using a large population-based dataset, we evaluated risk factors for operative intervention and mortality at readmission in patients with ASBO who were initially managed non-operatively. Methods ASBO patients were identified in the California Office of Statewide Health Planning and Development 2007-2014 patient discharge database. Patients who were managed operatively at index admission or had an ICD-9-CM diagnosis code for non-adhesive obstructive small bowel disease were excluded. Associations between risk factors and both operative intervention and death following readmission were evaluated using survival analysis. Results Among 15,963 ASBO patients, 3,103 (19.4%) had at least one readmission. The 1,069 (34.5%) who received an operation during their first readmission presented sooner (175 days versus 316 days, p
