“…Esophageal capsule endoscopy (ECE), a minimally invasive endoscopic technique, is preferred by patients who have suspected esophageal pathology but reject conventional esophageal endoscopy examination [1]. Previous studies have shown that ECE only has moderate sensitivity and specificity for the detection of distal esophageal diseases [2,3]. The limited diagnostic accuracy of ECE results mainly from partial or incomplete visualization of the distal esophagus, especially the Z-line.…”

“…This system was found to be highly sensitive in detecting PCG (93.9%) and fairly sensitive in detecting esophageal varices (82.4%). These results are somewhat better than those of previous-generation SB capsules, including esophageal capsules [36,37]. However, the system could not detect any of the six gastric varices probably because gastric varices are present as more localized lesions than PCG.…”

Background/AimsTo evaluate patients with portal hypertension (PH) of varied etiologies for portal hypertensive enteropathy (PHE) using the PillCam SB3 capsule endoscopy (CE) system. MethodsConsecutive patients with PH presenting with unexplained anemia and/or occult gastrointestinal bleeding were evaluated using the PillCam SB3 CE system. Abnormal findings were categorized as vascular or non-vascular. The patients with ongoing bleeding caused by PHE were treated. The correlation of the CE scores of PHE with the clinical, laboratory, and endoscopic features was determined. ResultsOf the 43 patients included in the study, 41 (95.3%) showed PHE findings. These included varices (67.4%), red spots (60.5%), erythema (44.2%), villous edema (46.5%), telangiectasia (16.3%), and polyps (16.3%). The CE scores varied from 0 to 8 (mean±standard deviation, 4.09±1.8). Five patients (11.6%) showed evidence of ongoing or recent bleeding due to PHE. Three of these five patients underwent endotherapy, and one patient underwent radiological coil placement. ConclusionsThe PillCam SB3 CE system revealed a high prevalence of PHE in the patients with PH. Using this system, evidence of bleeding due to PHE was found in a small but definite proportion of the patients.

“…Recently, McCarty et al evaluated ECE for the diagnosis and grading of medium to large EV in patients with portal hypertension in a systematic review and meta-analysis [ 24 ]. The authors collected 17 studies performed between 2005 and 2015 for a total patient pool of 1,328 [ 18 - 21 , 23 , 25 - 31 ]. The diagnostic accuracy of ECE in the diagnosis of EV was 90% (95% confidence interval [CI], 0.88–0.93).…”

Capsule endoscopy can be a diagnostic option for patients with esophageal diseases who cannot tolerate esophagogastroduodenoscopy.Functional modifications of the capsule allow for thorough examination of the esophagus. Esophageal capsule endoscopy has so farfailed to show sufficient performance to justify the replacement of traditional endoscopy for the diagnosis of esophageal diseasesbecause the esophagus has a short transit time and common pathologies appear near the esophagogastric junction. However,technological improvements are being introduced to overcome the limitations of capsule endoscopy, which is expected to become agood alternative to conventional endoscopy.
