Small bowel endoscopy in 2013: the reality and the potential.

2013 saw several advances in small bowel endoscopy: new 3D visualization software, increased battery life, side-viewing cameras and higher frame rate. Studies on prokinetics for patient preparation, safety in the elderly, rebleeding after negative capsule endoscopy and defining optimum training requirements for fellows were encouraging. Procedure time and small bowel length evaluated by double-balloon and spiral endoscopy were shown to be comparable.
