| 1 | Capsule endoscopy:Present status and future expectation显示文摘Video capsule endoscopy(CE)since its introduction 13years back,has revolutionized our approach to small intestinal diseases.Obscure gastrointestinal bleed(OGIB)continues to be the most important indication for CE with a high sensitivity,specificity as well as positive and negative predictive values.It is best performed during ongoing bleed or immediately thereafter.Overt OGIB has a higher diagnostic yield than occult OGIB.However,even in iron deficiency anemia,CE is emerging as important investigation after initial negative work up.In suspected Crohn’s disease(CD),CE has been shown superior to traditional imaging and endoscopic technique and should be considered after a negative ileocolonoscopy.Although CE has also been used for evaluating established CD,a high capsule retention rate precludes its use ahead of cross-sectional imaging.Celiac disease,particularly where gastro-duodenoscopy cannot be performed or is normal,can also be investigated by CE.Small bowel tumor,hereditary polyposis syndrome,and non-steroidal anti-inflammatory drugs induced intestinal damage are other indications for CE.Capsule retention is the only significant adverse outcome of CE and occurs mostly in presence of intestinal obstruction.This can be prevented by use of Patency capsule prior to CE examination.Presence of cardiac pacemaker and intracardiac devices continue to be relative contraindications for CE,though data do not suggest interference of CE with these devices.Major limitations of CE today include failure to control its movement from outside,inability of CE to acquire tissue for diagnosis,and lack of therapeutic help.With ongoing interesting and exciting developments taking place in these areas,these issues would be solved in all probability in near future.CE has the potential to become one of the most important tools in diagnostic and possibly in the therapeutic field of gastrointestinal disorder. | Mahesh K Goenka Shounak Majumder Usha Goenka | 2014 | World Journal of Gastroenterology2014，20，29： | 9 |
| 2 | Small bowel capsule endoscopy:Where are we after almost 15 years of use?显示文摘The development of capsule endoscopy(CE) in 2001 has given gastroenterologists the opportunity to investigate the small bowel in a non-invasive way. CE is most commonly performed for obscure gastrointestinal bleeding, but other indications include diagnosis or follow-up of Crohn's disease, suspicion of a small bowel tumor, diagnosis and surveillance of hereditary polyposis syndromes, Nonsteroidal anti-inflammatory drug-induced small bowel lesions and celiac disease.Almost fifteen years have passed since the release of the small bowel capsule. The purpose of this review is to offer the reader a brief but complete overview on small bowel CE anno 2014, including the technical and procedural aspects, the possible complications and the most important indications. We will end with some future perspectives of CE. | Cedric Van de Bruaene Danny De Looze Pieter Hindryckx | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，1： | 2 |
