Abstract

Purpose: To investigate patients with the lower gastrointestinal hemorrhage who presented to the emergency department requiring initial conventional angiography. We report risk-stratified and mesenteric conventional angiography outcomes.

 

Methods: Institutional Review Board approved the study. We reviewed patients with lower gastrointestinal bleeding consecutively and retrospectively between 2001 and 2012. We included all consecutive patients with clinical lower gastrointestinal bleeding with a requirement of further angiography and possible embolization. Prior interventions and surgical patients were excluded.

 

Results: We included 88 patients with a median age of 71 years (range 23-99), 35 women (39.8%) and 53 men (60.2%). Conventional angiography was positive and endovascular treatment was intended in 35/88 patients (40%). Once the source of bleeding was found angiographically, the technical success rate of endovascular treatment was 90.3% and clinical success rate was 71.4%. Overall early re-bleeding rate (<30 days) was 14.8% and late re-bleeding rate (>30 days) was 13.6%.

 

Conclusion: Identifying the source of lower gastrointestinal bleeding remains to be a clinical and angiographic challenge. Although we did not observe an association of mortality vs. clinical success; increased early re-bleeding rates are associated with higher mortality rates.
