Evaluation and management of small-bowel tumors in the era of deep enteroscopy

“….05). 94 Last, a prospective, single-center study showed an obvious advantage of total enteroscopy of DBE over SBE (57.1% vs 0%; P Z .49); but no difference in diagnostic yield (SBE 50% vs DBE 61%; P Z .49) or therapeutic outcomes (SBE 27% vs DBE 35%; P Z .63). 85 The decision to use DBE versus SBE should depend on operator experience, equipment availability, and the need for total enteroscopy.…”

“…51,52 Lastly, DBE can be used to evaluate patients with small-bowel stenosis, which may be a contraindication for CE. 94 There is a developing concept of emergent DBE without a prior CE. A small study of 10 patients with ongoing overt bleeding used this method based on the presentation of a patient with melena (anterograde approach) or hematochezia (retrograde approach).…”
