Details and patient eligibility

About

  1. Balloon-assisted enteroscopy (BAE) is a new tool to investigate small intestinal diseases.
  2. Deep enteroscopy made possible by balloon expansion and manipulation of small intestines.
  3. However, whether intestinal barrier injured during BAE predispose patients to bacteremia or clinical relevant infection is not studied.
  4. We will also examine relevant patient factors.

Full description

The newly developed balloon-assisted enteroscopy systems allow insertion of the enteroscopy deeply into the small intestines by fixation of the soft, redundant small intestines with an inflatable balloon over the tip of the overtube. However, the inflation of balloon might stimulate the intestinal mucosa, and the deep manipulation of intestinal segments might also compromise the intestinal barrier function. According to our preliminary experience of balloon-assisted enteroscopy (which is among the first groups in Taiwan), we experienced a significant case of suspected post-procedural bactermia patient. Besides, there is also a published case report from the UK reporting Streptococcus milleri bacteremia which is suspected as bacterial translocation after balloon-assisted enteroscopy. However, currently there is no original study focusing on the intestinal barrier / permeability defects or bacterial translocation. This is a timely and novel research topic in the current developing era of balloon-assisted enteroscopy.
