Aim Patients with inflammatory bowel disease (IBD) are diagnosed with anxiety/depression at higher rates than the general population. We aimed to determine the frequency of anxiety/depression among IBD patients and the temporal association with abdominal surgery and stoma formation.
MethodWe conducted a retrospective cohort study in adult patients with IBD using difference-in-difference methodology and a large commercial claims database (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016). Outcomes were anxiety/depression diagnoses before and after major abdominal surgery or stoma formation.
ResultsWe identified 10 481 IBD patients who underwent major abdominal surgery, 18.8% of whom underwent stoma formation, and 41 924 nonsurgical age-and sexmatched IBD controls who were assigned random index dates. Rates of anxiety and depression increased among all cohorts (P < 0.001). Surgical patients had higher odds of anxiety [one surgery, adjusted OR 6.90 (95% CI 6.11-7.79), P < 0.001; two or more surgeries, 7.53 (5.99-9.46), P < 0.001] and depression [one surgery, 6.15 (5.57-6.80), P < 0.001; two or more surgeries, 6.88 (5.66-8.36), P < 0.001] than nonsurgical controls. Undergoing multiple surgeries was associated with a significant increase in depression from 'pre' to 'post' time periods [1.43 (1.18-1.73), P < 0.001]. Amongst surgical patients, stoma formation was independently associated with anxiety [1.40 (1.17-1.68), P < 0.001] and depression [1.23 (1.05-1.45), P = 0.01]. New ostomates experienced a greater increase in postoperative anxiety [1.24 (1.05-1.47), P = 0.01] and depression [1.19 (1.03-1.45), P = 0.01] than other surgical patients.Conclusion IBD patients who undergo surgery have higher rates of anxiety and depression than nonsurgical patients. Rates of anxiety and depression increase following surgery. Stoma formation represents an additional risk factor. These findings suggest the need for perioperative psychosocial support services.

The relationship between surgery for inflammatory bowel disease, stoma formation, and anxiety and depression has been poorly quantified. We found that surgery for inflammatory bowel disease increased rates of anxiety and depression. Multiple surgeries and stoma-forming surgeries placed patients at additional risk. This suggests the need for additional psychosocial support services for these high-risk patients.
