Abstract

Background: Diagnosis and treatment of obscure gastrointestinal bleeding is a difficult problem in clinics, and digital subtraction angiography (DSA) has its unique advantages in the diagnosis of obscure gastrointestinal bleeding. Aims: To investigate the diagnostic and therapeutic values of DSA and interventional therapy in obscure gastrointestinal bleeding. Methods: DSA was performed in 82 patients with obscure gastrointestinal bleeding admitted in The Fourth Hospital of Harbin Medical University from Sept. 2008 to Oct. 2010, and the suspected lesions were treated by interventional therapy, such as arterial embolism and perfusion of drugs. Results: Of the 82 patients, DSA showed positive findings in 64 patients including 58 small intestinal bleeding and 6 postoperative anastomotic bleeding, the diagnosis rate was 78.0%. Twenty-two patients showed the direct sign of bleeding by contrast agent extravasation, and 42 patients showed indirect sign. The cause of bleeding was small intestinal tumor in 26 patients (40.6%), and diverticulum in 18 (28.1%). Seventeen patients were given interventional therapy, 16 arterial embolism and 1 perfusion of drugs with satisfactory responses. Conclusions: The position and cause of obscure gastrointestinal bleeding can be identified by DSA, and interventional therapy can be performed in some patients with high diagnostic and therapeutic values.
