Abstract

Background: Repeat ileocolic resection of Crohn’s disease (CD) is a challenging procedure that can be followed by a high rate of complications. The present study aimed to identify the factors associated with complications and conversion to open surgery in patients undergoing repeat ileocolic resection for CD. Methods: This was a retrospective review of an IRB-approved prospective database of CD patients who underwent elective repeat ileocolic resection between 2011 and 2021. Univariate and multivariate analyses were performed to determine the predictive factors of postoperative complications and conversion to open surgery. Results: The present study included 65 patients (47.7% male) with a mean age of 52.5 years. 43.1% of patients developed short-term complications, most of which were of Clavien–Dindo class I–II. Longer operative time was found to be an independent predictor of complications (OR 1.016, p = 0.014). The preoperative use of biological therapy was an independent protective factor from complications (OR 0.243, p = 0.016). The only significant risk factor of a longer operation time was higher BMI (OR 3.11, p = 0.044). Overall, 28.1% of laparoscopic procedures were converted to laparotomy. According to bivariate analysis, previous ileocolic open resection (OR 190, p < 0.0001), longer operation time (OR 1.01; p = 0.036), and takedown of incidental fistula of incidental fistula (OR 3.78, p = 0.04) were associated with higher odds of conversion to open surgery. Conclusion: Longer operation time was significantly associated with and predictive of complications after repeat ileocolic resection of CD. Preoperative biological therapy was predictive of a lower rate of complications. Previous ileocolic resection by laparotomy, longer operation time, and takedown of fistula were associated with a higher likelihood of conversion to open surgery.
