The successful completion of colonoscopy can be limited by endoscopist skill, bowel preparation, and loop- ing. 1 A variety of different techniques are available to manage looping, such as abdominal splinting, use of variable-stiffness colonoscopes, and reduction maneu- vers. 1-3 If cecal intubation remains difficult despite these maneuvers, overtube-assisted colonoscopy may help achieve this goal. This may include the use of single- balloon or double-balloon enteroscopy, spiral enteroscopy, or colonic overtubes.
