OBJECTIVE The aim of this study was to review our experience with patients having gynaecological surgeries while on long-term anticoagulation and to postulate a better guide for their perioperative management. MATERIAL AND METHODS A retrospective review of all women on long-term warfarin who underwent gynaecological surgeries from January 2003 to December 2012. Data from medical records including operation reports and inpatient and outpatient charts were reviewed and analyzed. RESULTS Sixty-seven cases from 58 patients were identified. Twenty and 38 patients underwent major and minor gynaecological surgeries, respectively. The incidence of postoperative bleeding was higher after major surgery (4 cases, 20%) than after minor surgery (1 case, 2.1%; P = 0.025). All bleeding complications occurred between postoperative day 3 and day 10. Three patients, who had resumption of warfarin at a lower dose and slowly stepped up, had no bleeding complications. None of our patients developed venous thromboembolic complications. There was one mortality due to septic shock. CONCLUSION Patients on long-term anticoagulation have a trend of increased bleeding complications after major gynaecological surgeries than in minor gynaecological surgeries. We suggest that delaying resumption of warfarin at a lower dose may have a role in reducing the risk of postoperative bleeding without increasing the risk of venous thromboembolism.
