Timing and Location of Venous Thromboembolisms After Surgery for Inflammatory Bowel Disease

Patients with inflammatory bowel disease are reported to be at elevated risk for postoperative venous thromboembolism (VTE). The rate and location of these VTE complications is unclear. Patients with ulcerative colitis (UC) or Crohn’s disease (CD) undergoing intestinal operations between January 2006 and March 2021 were identified from the medical record at a single institution. The overall incidence of VTEs and their anatomic location were determined to 90 days postoperatively. In 2716 operations in patients with UC, VTE prevalence was 1.95% at 1-30 days, 0.74% at 31-60 days, and 0.48% at 90 days (P
