In one study, researchers compared outcomes, including diagnostic yield, examination time, complications and maximal depth of insertion, for patients that underwent spiral and single-balloon enteroscopy. Results showed no different in diagnostic yield of examination duration between the two procedures. Spiral enteroscopy demonstrated a greater depth of maximal insertion than single-balloon enteroscopy. The author, however, points out that neither procedure was performed via retrograde approach and that the study was not a prospective, randomized trial.
In conclusion, Dr. Ross says the question of which system to purchase for deep small-bowel endoscopy remains a mystery, as there is still not sufficient data to support any one modality.
