Using a prediction tool to improve complete small-bowel exams with double-balloon enteroscopy

Effect of Predictive Model on Total Double-Balloon Enteroscopy Rate: a Randomized Controlled Trial

Not applicable Interventional Shandong University · NCT07288346

This trial will test whether a preoperative prediction model helps doctors achieve complete small-bowel examination during double-balloon enteroscopy in adults being evaluated for suspected small-bowel disease.

What this trial studies

Investigators will run a multicenter randomized trial comparing use of a preoperative predictive model to usual planning for double-balloon enteroscopy across three hospitals in Shandong, China. The model, previously developed and externally validated by the Department of Gastroenterology at Qilu Hospital, provides an individualized estimate of how difficult achieving total enteroscopy may be. Primary and secondary outcomes include total enteroscopy rate, detection of positive findings, procedure time, and adverse events. Eligible adults scheduled for an attempt at total enteroscopy must have a recent abdominal CT and meet standard anesthesia and consent criteria.

Who should consider this trial

Good fit: Adults aged 18–80 who are scheduled for an attempt at total enteroscopy for suspected small-bowel disease and who have had an abdominal CT within two weeks are the intended participants.

Not a fit: Patients with poor bowel preparation, high-risk esophageal varices, non-oral/anal altered anatomy, those unable to undergo general anesthesia, pregnant patients, or cases terminated at a target lesion are unlikely to benefit from the prediction model.

Why it matters

Potential benefit: If successful, the model could increase the rate of complete small-bowel exams and improve lesion detection while helping tailor procedure planning to lower procedure time and complications.

How similar studies have performed: This is the first prediction model developed specifically for double-balloon enteroscopy and it has undergone external validation, but randomized multicenter testing of its clinical impact is novel.
