Is emergency gastrointestinal system tumor surgery safe under treatment of antitrombotics?

BACKGROUND: The use of antitrombotic (antiaggregant and anticoagulant) drugs is increasing all over the world and in our country. About 12.6% of patients who underwent gastrointestinal tumor surgery receive antitrombotic therapy for various reasons, and in this study, we aimed to demonstrate the safe feasibility of elective or emergency gastrointestinal tumor surgery with the correct perioperative antitrombotic therapy management. METHODS: The patients who were planned for gastrointestinal tumor surgery under antitrombotic treatment were analyzed in three groups as those whose pre-operative treatment management treatment was discontinued, those who underwent bridging treatment, and those whose treatment continued. Anti-embolic stockings or intermittent pneumatic compression devices were applied to all patients preoperatively and postoperatively as mechanical prophylaxis. Post-operative complications, especially post-operative bleeding and thrombosis, were evaluated using the Clavien–Dindo post-operative complication classification. RESULTS: When patients who were under antithrombotic therapy, whose therapy was discontinued, and who underwent surgery under bridging therapy, no significant difference was found between the three groups in terms of bleeding complications. CONCLUSION: In tertiary centers with high clinical experience, elective and emergency gastrointestinal system tumour surgery can be safely performed under antitrombotic therapy without increasing the thromboembolic risk.
