Single-operator Versus Two-operator Technique in Single-balloon Enteroscopy

Condition(s) studied

Investigational drug(s) / intervention(s)

Single-Balloon Enteroscopy: Insertion procedure of single-balloon enteroscopy. (1) Insert the scope. (2) Angulate the scope to hold the gut and deflate the balloon. (3) Advance the splinting tube. (4) Inflate the balloon. (5) Withdraw both the scope and splinting tube while releasing the angulation. (6) Withdraw both the scope and splinting tube to shorten the intestine. (7) Repeat these steps until the scope reaches the deep part of the small bowel.

Study summary

Compared to two-operator single-balloon enteroscopy, single-operator procedure not only offer better maneuverability but may also prevent prolonged examination times and potential complications caused by poor coordination between operators. Additionally, it can optimize staffing in the endoscopy suite. However, there are no studies comparing the effects of single-operator and two-operator techniques on single-balloon enteroscopy.

Eligibility
