Since its introduction into clinical practice 15 years ago,capsule endoscopy(CE)has become the first-line investigation procedure in some small bowel pathologies,and more recently,dedicated esophageal and colon CE have expanded the fields of application to include the upper and lower gastrointestinal disorders.During this time,CE has become increasingly popular among gastroenterologists,with more than 2 million capsule examinations performed worldwide,and nearly 3000Pub Med-listed studies on its different aspects published.This huge interest in CE may be explained by its noninvasive nature,patient comfort,safety,and access to anatomical regions unattainable via conventional endoscopy.However,CE has several limitations which impede its wider clinical applications,including the lack of therapeutic capabilities,inability to obtain biopsies and control its locomotion.Several research groups are currently working to overcome these limitations,while novel devices able to control capsule movement,obtain high quality images,insufflate the gut lumen,perform chromoendoscopy,biopsy of suspect lesions,or even deliver targeted drugs directly to specific sites are under development.Overlooking current limitations,especially as some of them have already been successfully surmounted,and based on the tremendous progress in technology,it is expected that,by the end of next 15years,CE able to perform both diagnostic and therapeutic procedures will remain the major form of digestive endoscopy.This review summarizes the literature that prognosticates about the future developments of CE.
