Venous thromboembolism (VTE) is a leading cause of postoperative mortality in bariatric surgical patients.
Advanced age, major orthopedic surgery, neoplastic disease, prolonged operations, varicose veins, immobilization, estrogen-containing medications, and obesity are known risk factors for the development of postoperative thromboembolic complications.
After bariatric surgery, early or late adverse events, such as intraluminal or extraluminal gastrointestinal hemorrhage, can occur.
General Recommendations for Pre-Procedure Warfarin Management
Laparoscopic bariatric surgery: Hold warfarin x5 days and resume anticoagulation 24 hours after surgery.
