Purpose : To describe the usefulness of small bowel enteroclysis using a hemodialysis blood pump. Materials and Methods : Over a 16 month period, 135 double contrast small bowel enteroclysis examinations were performed in 132 patients using a hemodialysis blood pump. Following intubation of the proximal jejunum, barium at a dilution of 50% and 0.5% methylcellulose were infused at a constant rate using a hemodialysis blood pump and multiple spot films of the small intestine were obtained. Success rate, quality of radiographs, positive findings, fluoroscopic time and complications were evaluated. Results : Only two of 135 examinations (1.5%) failed due to lack of cooperation by the patient. Rates of good distensability were 97.6% in the proximal portion, 91.2% in the mid portion and 52% in the distal portion and rates of good transparency were 96%, 84% and 56% respectively. Transparency and distensability of the small intestine were better in proximal than distal small bowel. The radiographs showed positive findings in 25% of cases. The mean fluoroscopic time was 21min, 10 sec(8min, 22sec-57min, 30sec). No major complication was found during or after examination. Conclusion : It spite of the long fluoroscopic time and invasiveness, double contrast small bowel enteroclysis is useful for the evaluation of small bowel disease. The infusion of barium and methylcellulose using a hemodialysis blood pump give radiographs of good quality.
