Capsule endoscopy in patients refusing conventional endoscopy. World J Gastroenterol 2014; 20(23):7424-743320141007-9327http://hdl.handle.net/10668/2697Journal Article; Review;Capsule endoscopy is nowadays the diagnostic technique of choice in the study of small bowel pathologies, allowing the non-invasive study of the entire mucosa. This has led, together with new technical advances, to the creation of two new models (PillCam ESO and PillCam Colon) for the study of esophageal and colonic diseases. These two new capsules offer an interesting alternative to conventional endoscopy in the study of the upper and lower digestive tracts, because traditional endoscopy is often unpleasant and uncomfortable for the patient, can be painful, often requires moderate or deep sedation and is not without complications (hemorrhage, perforation, etc.). PillCam Colon is particularly important for its usefulness in the diagnosis of colonic polyps, and is a potentially useful tool in cases of incomplete colonoscopy or in colorectal cancer screening, even more when most patients are reluctant to undergo screening programs due to the said disadvantages of conventional colonoscopy. This article discusses the advantages of capsule endoscopy over conventional endoscopy, its current application possibilities and indications in routine clinical practice. In the various sections of the work, we assess the application of endoscopic capsule in different sections of the digestive tract (esophagus, stomach, and colon) and finally the potential role of panendoscopy with PillCam Colon.enConventional endoscopyCapsule endoscopyEsophageal capsule endoscopyColon capsule endoscopyPanendoscopyEndoscopía capsularColonoscopíaGastroscopíaConocimientos, actitudes y práctica en saludNegativa del paciente al tratamientoMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Techniques, Surgical::Endoscopy::Endoscopy, Digestive System::Endoscopy, Gastrointestinal::Capsule EndoscopyMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Equipment and Supplies::Diagnostic Equipment::EndoscopesMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Techniques, Digestive System::Endoscopy, Digestive System::Endoscopy, Gastrointestinal::ColonoscopyMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Equipment DesignMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Equipment and Supplies::Diagnostic Equipment::Endoscopes::Endoscopes, Gastrointestinal::EsophagoscopesMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Techniques, Digestive System::Endoscopy, Digestive System::Endoscopy, Gastrointestinal::EsophagoscopyMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Equipment and Supplies::Diagnostic Equipment::Endoscopes::Endoscopes, Gastrointestinal::GastroscopesMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Techniques, Digestive System::Endoscopy, Digestive System::Endoscopy, Gastrointestinal::GastroscopyMedical Subject Headings::Health Care::Health Care Quality, Access, and Evaluation::Delivery of Health Care::Attitude to Health::Health Knowledge, Attitudes, PracticeMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Named Groups::Persons::PatientsMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Research Design::Sensitivity and Specificity::Predictive Value of TestsMedical Subject Headings::Disciplines and Occupations::Social Sciences::Sociology::Social Control, Formal::Human Rights::Patient Rights::Treatment RefusalMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Equipment and Supplies::Diagnostic Equipment::Endoscopes::Endoscopes, Gastrointestinal::Capsule Endoscopesreview article24966612open access10.3748/wjg.v20.i23.74242219-2840PMC4064087
