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

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.
