title: Small bowel enteroscopy: territory conquered, future horizons.
abstract: OBJECTIVE
  To review recent advances in small bowel enteroscopy, focusing on indications, modifications to improve imaging and techniques, pitfalls, and clinical applications.
  
  
  RESULTS
  The need for endoscopic access to improve diagnosis and treatment of small bowel disease has led to the development of novel technologies, video capsule, and double balloon endoscopy. Newer devices, single balloon and spiral endoscopy, are just entering clinical use. With new technologies come the trials and tribulations of learning new endoscopic skills and determining their role in the diagnosis and treatment of small bowel disease. Identification of small bowel lesions has dramatically improved. However, small bowel angulations, peristalsis, and bilious fluid in the lumen can result in false readings or missed lesions. Studies are underway to determine the best strategy to apply new enteroscopy technologies for the diagnosis and management of small bowel disease, particularly bleeding.
  
  
  CONCLUSIONS
  Complete enteroscopy of the small bowel is now possible. However, because of the length of the small bowel, endoscopic examination and therapeutic maneuvers require patience and significant skill. Prospective randomized studies are needed to guide diagnostic testing and therapy with these new endoscopic techniques.
