Abstract
Background and Aims: Recommendations for the treatment of lower GI bleeding do not include bleeding from venous malformations (VMs). The aim of this study was to delineate the usefulness of a novel hybrid intervention (fluoroscopy-guided endoscopic sclerotherapy) for the treatment of symptomatic VMs in the rectosigmoidal colon with bleeding. Methods: The magnetic resonance images of 421 patients with VM, referred to multicenter vascular anomaly centers from 2009 to 2017, were analyzed retrospectively. Treatment was performed for all patients who experienced bleeding from rectosigmoidal VMs using fluoroscopy-guided endoscopic sclerotherapy with polidocanol foam as a novel approach. Results: A total of 27 patients displayed VM in the rectosigmoidal area. Eleven of these presented with acute or previous bleeding and received treatment. Active bleeding was observed in 8 patients (72.7%), whereas 3 patients (27.3%) had signs of previous bleeding. Six of the 11 patients had anemia (54.5%). There were no adverse events within 24 hours of the intervention. In a 2-year follow-up period, only 1 patient (9.1%) presented with recurrent bleeding after 13 months and was successfully treated again with fluoroscopy-guided endoscopic sclerotherapy. Conclusions: Fluoroscopy-guided endoscopic sclerotherapy was shown to be a safe and effective treatment of symptomatic VMs of the rectosigmoidal area. Thus, fluoroscopy-guided endoscopic sclerotherapy should be considered for patients with bleeding from VMs of the rectosigmoid after a comprehensive workup and interdisciplinary case discussion.
