Abstract
Background/Objectives: Intestinal Behçet’s disease (iBD) often requires surgical intervention, with a significant proportion of patients needing reoperation. This study aimed to investigate the risk factors associated with reoperation in patients with iBD who underwent initial bowel resection and to evaluate the perioperative and long-term outcomes in these patients. Methods: This was a retrospective case-control study analyzing patients who underwent their initial bowel resection due to iBD between 2005–2021 at a tertiary referral hospital. Reoperation was considered a surgery due to postoperative complications (within 30 days of the initial surgery) or disease progression. Results: A total of 81 patients were included. The median follow-up duration was 107.1 months, during which 26 patients (32%) underwent reoperation. Multivariable analysis showed that the presence of hematological disorders (hazards ratio [HR], 9.13; 95% confidence interval [CI], 3.79–22.02, p < 0.001), higher c-reactive protein (CRP) levels before the initial surgery (HR, 1.01; 95% CI, 1.01–1.02, p < 0.001), and a shorter specimen resection length (HR, 0.96; 95% CI, 0.93–0.99, p = 0.011) were risk factors for reoperation. Patients who underwent reoperation had higher rates of postoperative complications (69.2% vs. 43.6%, p = 0.031), required longer antibiotic use (12 vs. 7 days, p = 0.012), and had extended hospital stays (18 vs. 9 days, p = 0.011). They also had worse 5-year survival rates than those who did not undergo reoperation (83.5% vs. 98.4%, p = 0.012). Conclusions: Concurrent hematological disorders, high preoperative CRP levels, and short specimen resection were associated with an increased risk of reoperation in patients with iBD who underwent their initial bowel resections. They also had worse perioperative and long-term outcomes.
