Abstract
(1) Background: Villous atrophy is an indication for small bowel capsule endoscopy (SBCE). However, SBCE findings are not described uniformly and atrophic features are sometimes not recognized; (2) Methods: The Delphi technique was employed to reach agreement among a panel of SBCE experts. The nomenclature and definitions of SBCE lesions suggesting the presence of atrophy were decided in a core group of 10 experts. Four images of each lesion were chosen from a large SBCE database and agreement on the correspondence between the picture and the definition was evaluated using the Delphi method in a broadened group of 36 experts. All images corresponded to histologically proven mucosal atrophy; (3) Results: Four types of atrophic lesions were identified: mosaicism, scalloping, folds reduction, and granular mucosa. The core group succeeded in reaching agreement on the nomenclature and the descriptions of these items. Consensus in matching the agreed definitions for the proposed set of images was met for mosaicism (88.9% in the first round), scalloping (97.2% in the first round), and folds reduction (94.4% in the first round), but granular mucosa failed to achieve consensus (75.0% in the third round); (4) Conclusions: Consensus among SBCE experts on atrophic lesions was met for the first time. Mosaicism, scalloping, and folds reduction are the most reliable signs, while the description of granular mucosa remains uncertain.

Abstract
Background Gastrointestinal stromal tumors (GISTs) are rare tumors, accounting for 1–3% of all gastrointestinal malignancies; they are, however, the most common gastric and small bowel mesenchymal tumors. The length and relative inaccessibility of the small bowel have long constrained the diagnosis of GISTs mainly presenting with chronic or intermittent bleeding as the sole clinical manifestation. Aim To report on the prevalence of small bowel GISTs in a prospectively recorded series of patients undergoing capsule endoscopy (CE). Patients and methods Between 2001 and 2007 five hundred patients were referred to our endoscopy unit for small bowel evaluation with capsule endoscopy. We retrospectively evaluated all charts. The main indications for CE were obscure-occult or obscure-overt bleeding. Two hundred eighty-nine patients underwent CE for either obscure-occult or obscure-overt bleeding and 211 for other indications. Patient outcome and care processes were measured by follow-up telephone interviews and chart review. Statistical computations were performed using Fisher's exact test and Student's t-test. Results CE identified a small bowel tumor in 20 patients (4.0%) and 9 tumors turned out to be GISTs (45.0%). Traditional endoscopic and radiological imaging failed to detect the GIST in all these cases. In one case a small bowel GIST was diagnosed by angiography and CE proved false negative. Overall, CE was able to diagnose a small bowel GIST in 9 out of 10 cases. All patients underwent surgical treatment and showed normalized hemoglobin levels at follow-up. The main limitation of this study is the small number of cases. Conclusions CE is an effective and sensitive diagnostic device compared with conventional radiology and plays an important role in the algorithm for the diagnostic work-up of suspected small bowel tumors.

Abstract
Objective: The aim of this study was to evaluate the detection rate accuracy of Double-balloon Enteroscopy (DBE) after Capsule Endoscopy (CE) in patients with suspected small bowel diseases. Methodology: From January 2009 to March 2012, sixty-two patients with obscure small bowel diseases who underwent CE followed by DBE were included in this study. Introduction of the endoscope by DBE was either orally or anally according to CE. Results: Sixty-two patients are reported. The overall detection rate of small bowel diseases using CE was 70.9% (44/62). Sixty-eight DBE procedures following capsule endoscopy were carried out, There was no significant difference (χ2=0.6739, P>0.05) of Positive findings between CE and CE +DBE. Furthermore, the detection rate of small bowel diseases in patients with obscure small intestinal bleeding using CE +DBE (90.9%, 30/33) was superior to that of CE (78.8%, 26/33); χ2=1.8857, P>0.05. Conclusions: Capsule Endoscopy (CE) can cover the whole GI tract and provide the selection of the route of Double-balloon enteroscopy (DBE). DBE can also serve as a good complementary approach after an initial imaging using CE. It can verify the findings of CE and provide therapeutic intervention. Using of CE followed by DBE is effective in the diagnosis and management of patients with obscure small bowel diseases.

Abstract
This paper presents a novel solution of a hand-held external controller to a miniaturized capsule endoscope in the gastrointestinal (GI) tract. Traditional capsule endoscopes move passively by peristaltic wave generated in the GI tract and the gravity, which makes it impossible for endoscopists to manipulate the capsule endoscope to the diagnostic disease areas. In this study, the main objective is to present an endoscopic capsule and a magnetic field navigator (MFN) that allows endoscopists to remotely control the locomotion and viewing angle of an endoscopic capsule. The attractive merits of this study are that the maneuvering of the endoscopic capsule can be achieved by the external MFN with effectiveness, low cost, and operation safety, both from a theoretical and an experimental point of view. In order to study the magnetic interactions between the endoscopic capsule and the external MFN, a magnetic-analysis model is established for computer-based finite-element simulations. In addition, experiments are conducted to show the control effectiveness of the MFN to the endoscopic capsule. Finally, several prototype endoscopic capsules and a prototype MFN are fabricated, and their actual capabilities are experimentally assessed via in vitro and ex vivo tests using a stomach model and a resected porcine stomach, respectively. Both in vitro and ex vivo test results demonstrate great potential and practicability of achieving high-precision rotation and controllable movement of the capsule using the developed MFN.

Abstract
AIM: To investigate and evaluate the feasibility of the computer-aided screening diagnosis for enteric lesions in the capsule endoscopy (CE).
METHODS: After developing a series of algorithms for the screening diagnosis of the enteric lesions in CE based on their characteristic colors and contours, the normal and abnormal images obtained from 289 patients were respectively scanned and diagnosed by the CE readers and by the computer-aided screening for the enteric lesions with the image-processed software (IPS). The enteric lesions shown by the images included esoenteritis, mucosal ulcer and erosion, bleeding, space-occupying lesions, angioectasia, diverticula, parasites, etc. The images for the lesions or the suspected lesions confirmed by the CE readers and the computers were collected, and the effectiveness rate of the screening and the number of the scanned images were evaluated, respectively.
RESULTS: Compared with the diagnostic results obtained by the CE readers, the total effectiveness rate (sensitivity) in the screening of the commonly-encountered enteric lesions by IPS varied from 42.9% to 91.2%, with a median of 74.2%, though the specificity and the accuracy rates were still low, and the images for the rarely-encountered lesions were difficult to differentiate from the normal images. However, the number of the images screened by IPS was 5000 on average, and only 10%-15% of the original images were left behind. As a result, a large number of normal images were excluded, and the reading time decreased from 5 h to 1 h on average.
CONCLUSION: Though the total accuracy and specificity rates by the computer-aided screening for the enteric lesions with IPS are much lower than those by the CE readers, the computer-aided screening diagnosis can exclude a large number of the normal images and confine the enteric lesions to 5000 images on average, which can reduce the workload of the readers in the scanning of the images. This computer-aided screening technique can make a correct diagnosis as efficiently as possible in most of the patients.

Abstract
This paper describes a technique to control the navigation of traditional wireless endoscopic capsules and reports preliminary proof-of-concept investigations. These capsules are used for noninvasive explorations of the digestive tube. At present, their motion cannot be controlled and they proceed by means of the visceral peristalsis. In order to enable motion controls, the technique proposed here adopts magnetic shells which are to be applied to available capsules, immediately before their use. The shells are used to control the capsule movement by means of external magnetic fields. This solution is readily applicable to any endoscopic capsule, avoiding internal modifications. Prototype elastic shells made of silicone elastomers mixed with magnetic particles were fabricated. They were tested with the most diffused capsule (model M2A, Given Imaging Ltd., Yoqneam, Israel), by studying the performance of the capsule/shell complex in simplified experimental conditions. Bench tests permitted to demonstrate controlled translations, rotations, and rototranslations of the capsule/shell complex within tubular structures coated with pieces of bovine tissues. The use of a new instrumentation, recently developed for cardiovascular treatments, is proposed as a potential means enabling the application of controlled magnetic fields for intrabody navigations.
