Safety and Feasibility of Percutaneous Gastrostomy Placement in Patients on Antiplatelet Therapy

Background: Guidelines recommend the discontinuation of clopidogrel prior to gastrostomy tube placement. The aim of this study was to examine the safety and feasibility of performing radiologically inserted gastrostomy (RIG) tube placement in patients taking clopidogrel and/or aspirin. Methods: We performed an institutional review board–approved retrospective analysis of the medical records for 237 consecutive patients following RIG tube placement secondary to dysphagia from August 2017 to January 2019. Antiplatelet medications and RIG type placement techniques (push vs pull) were compared with bleeding complications. Complications were categorized based on the Society of Interventional Radiology clinical practice guidelines. Of the 237 patients with RIG tubes placed, 77 patients were on antiplatelet therapy: 55 on single antiplatelet therapy and 22 on dual antiplatelet therapy. Of the 55 patients on single antiplatelet therapy, 26 were taking clopidogrel and 29 were taking aspirin. Results: A total of 9 bleeding complications were observed. The most common complication was minimal bleeding or hematoma around the incision site (n=7). No statistically significant increase was seen in bleeding rates when comparing patients on any antiplatelet therapy regimen vs none (P=0.15), single antiplatelet therapy vs none (P=0.13), clopidogrel vs none (P=0.71), or dual antiplatelet therapy vs none (P=0.61). No significant increase in the bleeding complication rate was noted when comparing the aspirin-only regimen vs clopidogrel alone (P=0.34). Conclusion: These findings suggest that the risk of bleeding complications is not increased in patients taking clopidogrel and/or aspirin prior to RIG tube placement.
