Background: The identification of patients prone to early recurrence of Crohn's disease at the site of a strictureplasty is fundamental in the clinical practice.
Aims: Aim of the study is to detect the risk factors for early reoperation for recurrence after primary strictureplasty.
Methods: From 2000, patients undergoing a primary strictureplasty and a subsequent reoperation for recurrence of Crohn's disease at the site of a strictureplasty were included. Univariate and multivariable linear regression models were performed to analyse the relationship between the time to recurrence and independent variables.
Results: Fifty-nine patients were included. Median time to recurrence was 4.5 years (0.7-12.6). At the multivariate linear regression, early relapse was significantly associated with use of biologics before primary surgery (-2.69, p < 0.0001) and location of disease in the ileum (-1.61, p 0.017). The use of biologics after surgery was similar between groups (40.7 vs 37.5%, p 0.79).
Conclusions: The location of Crohn's disease in the ileum and the use of biologics before surgery are strong predictors of early site-specific recurrence after strictureplasty. In this group of patients, a tailored follow-up and aggressive postoperative treatment should be considered.
