Randomized crossover trial comparing through-the-scope balloon enteroscopy via colonoscope with standard colonoscopy on depth of ileal insertion.

ABSTRACT:

Background and aims

Retrograde enteroscopy for evaluation of the small bowel can be performed using through-the-scope balloon-assisted enteroscopy (TTSE). TTSE consists of a balloon catheter designed for anchoring in the small bowel, inserted through the instrument channel of a standard colonoscope. We aimed to assess the ability of TTSE to improve the depth of maximal ileal insertion (DMI) compared with the colonoscope alone (C1).

Methods

We performed a prospective, randomized, crossover study to compare the DMI between TTSE and enteroscopy using the adult colonoscope alone. After measuring the DMI by the randomized sequence, the endoscopist switched the technique and measured the DMI again. The primary end point of the study was a comparison of DMI (centimeters) between th
