Background and aims
Until recently the study of small bowel was limited to the radiographic approach. This paper describes experience with the first 86 procedures evaluated and treated with the new technique of double-balloon enteroscopy (DBE).
Patients and Methods
Between August 2005 and September 2006, DBE was conducted in consecutive patients. The characteristics of the patients, indications for the procedures, procedural parameters, and diagnostic yield are described here. All conventional treatment options were available. All the patients had previously undergone esophagogastroduodenoscopy and colonoscopy.
Results
Eighty-six procedures in sixty-eight patients were carried out (41 women, 27 men; mean age 48.5 years, range 20–82). The most common indications were gastrointestinal bleeding (n = 40) and iron deficiency anemia (n = 7). The mean duration of the procedure was 63 (range 20–194) mins and 80 (range 20–150) minutes for the oral and anal routes, respectively. The mean depth of small-bowel insertion was 250 and 200 cm for the oral and anal routes, respectively. Impact in diagnosis and/or treatment was obtained in 50 patients (73.5%). The commonest findings in the 68 patients were angiodysplasia (n = 11), polyps (n = 8), nodular lymphoid hyperplasia (n = 5) and normal (n = 20). No major complications were observed.
Conclusion
DBE is a useful tool for the diagnosis and treatment of patients with small-bowel pathology in whom traditional methods have not been effective. In almost two-thirds of patients DBE was clinically useful for diagnosis and treatment. The complication rate with the procedure was very low.
