“…The new second-generation PCC2 is similar to PCC1 with many new features. PCC2 has a wider angle of view (172° versus 156° for the firstgeneration colon capsule), allowing almost 360° coverage [Adler and Metzger, 2011;Sieg, 2011]. A new data recorder (DR3) in PCC2 has an adaptive frame rate of 4-35 frames/s, the ability to generate customized alerts at different points to guide the patient or physician, and real-time visualization capacity.…”

Colon capsule endoscopy (CCE) is being actively evaluated as an emerging complementary or alternative procedure for evaluation of the colon. The yield of CCE is significantly dependent on the quality of bowel preparation. In addition to achieving a stool-free colon the bowel preparation protocols need to decrease bubble effect and aid propulsion of the capsule. An extensive English literature search was done using PubMed with search terms of colon capsule endoscopy, PillCam and bowel preparation. Full-length articles which met the criteria were included for review. A total of 12 studies including 1149 patients were reviewed. There was significant variability in the type of bowel preparation regimens. Large-volume (3-4 liters) polyethylene glycol (PEG) was the most widely used laxative. Lower volumes of PEG showed comparable results but larger studies are needed to determine efficacy. Sodium phosphate was used as an effective booster in most studies. Magnesium citrate and ascorbic acid are emerging as promising boosters to replace sodium phosphate when it is contraindicated. The potential benefit of prokinetics needs further evaluation. Over the past decade there has been significant improvement in the bowel preparation regimens for CCE. Further experience and studies are likely to standardize the bowel preparation regimens before CCE is adopted into routine clinical practice.

“…WCE has proven invaluable in evaluating various diseases of the small bowel such as obscure bleeding, polyps andneoplasm, Crohn's disease, celiac disease and mucosal ulcers [1] [17][29]. Ulcer isone of the most common lesions of the GI tract that affects approximately 10% of the people.The most usual causes are Helicobacter pylori bacteria and use of nonsteroidalantinflammatory drugs (NSAID).…”

the main contribution of this paper is the presentation of a novel tool for WCE image analysis and classification by exploiting color-texture features. The proposed scheme has based on the ingenious combination of optimal selection of image components (IMFs) ofBEEMD and DLac, applied on the green/red component of WCE images in order to identify ulcerations and polyp affected images from WCE images.Optimal IMF's of BEEMDwas exploited to reveal the intrinsic components (IMFs) of the images in order to achieve data driven, Coefficient of standard Deviation and efficient SVM classifier to boost the distinctness between polyp and ulcer regions. However, DLac analysis facilitates to extract efficient texturecharacteristics. The proposed approach has evaluated on selected WCE images, captured from patients, depicting ulcer and polyp tissue.The optimum image components (IMFs) that contain the majority of texture information include IMFs 5-8which produce 100% accuracy for ulcer images. Individual IMFs score up to 80 % classification accuracy, while their higher exploitation as a group enhances the detection rate up to 93.34% for ulcer and 90% for polyp tissue.

“…Yet the critical question to be addessed is whether this new capsule endoscope leads to improved diagnostic performance compared to traditional colonoscopy. Studies (Adler & Metzger, 2011) indicate that the diagnostic yield of WCE in colon has increased but still cannot surpass colonoscopy.…”
