Abstract
BACKGROUND:
The optimal venous thromboembolism chemoprophylaxis strategy after surgery for inflammatory bowel disease is not defined.
OBJECTIVE:
To investigate the real-world efficacy of chemoprophylaxis strategies after surgery for inflammatory bowel disease in a retrospective cohort.
DESIGN:
From July 2020 to October 2023, the National Surgical Quality Improvement Program Inflammatory Bowel Disease Collaborative.
SETTING:
Seventeen medical centers.
PATIENTS:
Inflammatory bowel disease patients undergoing colectomy and/or proctectomy.
INTERVENTIONS:
Chemoprophylaxis.
MAIN OUTCOME MEASURES:
Thirty-day venous thromboembolism (clot) rates.
RESULTS:
Over 3 years, 1,797 patients were eligible for chemoprophylaxis and analyzed, of whom 44 (2.4%) developed a clot within 30-days: 50% before and after discharge, respectively. Clots were diagnosed a median of 9 days postoperatively. The most common clots were portomesenteric (39%), pulmonary embolism (27%), and upper extremity (18%). Prior to discharge, clot rates differed by chemoprophylaxis strategy: enoxaparin (0.57%) vs. unfractionated heparin (2.1%), p = 0.006. Any extended chemoprophylaxis was used in 50.5% and clot rates differed by strategy: no extended chemoprophylaxis (1.4%), enoxaparin (0.63%), and others (3.5%) p = 0.01. Chemoprophylaxis strategies were not associated with bleeding complications. Multivariable analysis revealed preoperative systemic inflammatory response syndrome (p = 0.0005) and extended resections (p < 0.0001) were independent risk factors for postoperative clots. Patients with 0, 1, or 2 risk factors had clot rates of 1.2%, 4.0%, and 13.5%, respectively (p < 0.0001). Inpatient and extended prophylaxis with enoxaparin were independently associated with a lower risk of clots before and after discharge (p = 0.002 and p = 0.02, respectively), with relative risk reductions of 74.8% and 72.6%. For a clot rate of 2.5%, the estimated number needed to treat with enoxaparin in-hospital and post-discharge of 54 and 55 patients, respectively.
LIMITATIONS:
Generalizability; selection bias.
CONCLUSIONS:
After inflammatory bowel disease surgery, venous thromboembolism chemoprophylaxis with enoxaparin was associated with decreased clot risk before and after discharge. Patients at highest risk may benefit the most from extended chemoprophylaxis. See Video Abstract.
