| [ Summary ] | Small-bowel vascular lesions are a common cause of obscure gastrointestinal bleeding. Notably, close monitoring is warranted for bleeding in elderly patients, patients using anticoagulants or those with cardiovascular disease, liver cirrhosis, or chronic renal failure. Treatment of small-bowel vascular lesions includes endoscopic treatment, interventional radiology (IVR), or surgery, and polidocanol injection (PDI) via balloon endoscopy is a safe and simple option. The main indications for PDI are angioectasia (Yano-Yamamoto classification Type 1) and cavernous hemangioma. Furthermore, PDI is useful as adjunctive therapy for Type 2 or Type 3 lesions. | |
