Push enteroscopy and heater probe therapy for small bowel bleeding.

Author information

Department of Gastroenterology, Glasgow Royal Infirmary, Scotland.



Blood loss from the small bowel is a significant cause of obscure gastrointestinal bleeding. Small bowel angiodysplasia may be the source of bleeding in 30% to 40% of patients with this problem. In other areas of the bowel, angiodysplasia has been effectively treated by endoscopic methods.


We used a 1.7 meter push enteroscope and heater probe ablation to examine and treat 11 transfusion-dependent patients with significant bleeding from small bowel angiodysplasia. Patients had push enteroscopy to target all lesions identified and had follow-up hemoglobin and fecal occult blood tests for a minimum of 6 months after final enteroscopy.


There were a median of 2 (range 1 to 7) small bowel lesions per patient. Patients required a median of 1 (range 1 to 5) examination to treat lesions identified at enteroscopy. Following therapy, hemoglobin levels rose significantly from a median of 8.5 (range 5.3 to 10.6) gm/dL) to a median of 13.5 (range 7.6 to 16.5) gm/dL (p < 0.01 Wilcoxon matched pair signed rank test).


Push enteroscopy and heater probe ablation offer potential therapy for bleeding from small bowel angiodysplasia and result in reduction of blood loss and transfusion requirements along with a significant improvement in levels of hemoglobin.
