Clinical and surgical factors for successful stoma reversal in patients with Crohn's disease-results of a retrospective cohort study

Purpose Despite the wide range of medical and interventional therapy options available, some patients with Crohn's disease (CD) need an ileostomy or colostomy. The aim of this study was to identify clinical, surgical and drug-related predictors of successful stoma reversal in CD patients. Methods A retrospective medical record analysis of surgical department logs, hospital discharge letters and patient reports from outpatient departments was performed for all CD patients who underwent a first ostomy surgery. Results Our study analysed a total of 149 patients (76 women, 73 men, median age at first stoma of 34 years after a median CD duration of 9 years), with a median follow-up of 78.4 (IQR 88.6) months after first ostomy surgery. Of these patients, 73 (49%) underwent stoma reversal after a median of 11.7 months (IQR 15.7 months) of whom 17 (23.3%) needed a second stoma. In multivariant analysis, Montreal A1 classification (HR 2.07; 95% confidence interval 1.23-3.47; p = 0.006), a primary laparotomy (HR 2.30; 95% confidence interval 1.20-4.41; p = 0.012) and the absence of perianal/rectal CD activity (HR 3.00; 95% confidence interval 1.86-4.86; p < 0.001) emerged as independent predictors of a shorter time to stoma reversal. Introduction or switch of biological therapy after first stoma was not associated with successful reversal of the stoma (OR 4.6 95% confidence interval 1.45-14.66; p = 0.01). Laboratory parameters had no influence. Conclusion Clinical and surgical features-rather than medication or laboratory findings-were found to be predictors of successful stoma reversal in CD patients. Future studies focusing on the definition of a Standard Operation Procedure for emergency and elective CD surgery are warranted.

Automated summary

This study aimed to identify clinical, surgical, and drug-related predictors of successful stoma reversal in CD patients. The results showed that clinical and surgical features were more predictive of a successful stoma reversal in CD patients, while medication or laboratory results had little influence.
