Abstract
Background The role of capsule endoscopy in the evaluation of the small bowel is well established, and current guidelines position it as a first-line test in a variety of clinical scenarios. The advent of double-headed capsules further enabled the endoscopic assessment of colonic mucosa and the opportunity for a one-step noninvasive examination of the entire bowel (pan-enteric capsule endoscopy [PCE]). Summary We reviewed the technical procedure and preparation of patients for PCE, as well as its current clinical applications and future perspectives. In non-stricturing and non-penetrating Crohn's disease affecting the small bowel and colon, PCE monitors disease activity by assessing mucosal healing, a major treatment outcome, with a higher diagnostic yield than cross-sectional imaging or conventional colonoscopy. Also in ulcerative colitis, double-headed capsules have been used to monitor disease activity noninvasively. Currently, validated scoring systems have been specifically devised for these double-headed capsules and permit a standardized assessment of the inflammatory burden. In suspected mid-lower digestive bleeding, some exploratory studies have demonstrated the feasibility and high diagnostic yield of PCE, which may work as a filter indicating which patients may benefit of further invasive procedures, namely, for planned hemostatic procedures. The possibility of using PCE is also discussed in the context of polyposis syndromes with simultaneous involvement of the small intestine and colon. Key Messages PCE is a feasible, effective, and safe diagnostic procedure to evaluate the small bowel and colon. It has been increasingly explored in the setting of inflammatory bowel diseases and, more recently, in suspected mid-lower digestive bleeding. PCE is expected to reduce the demand for invasive procedures and expand the scope of noninvasive intestinal evaluation in the coming future.

Abstract
In 2000, the small bowel capsule revolutionized the management of patients with small bowel disorders. Currently, the technological development achieved by the new models of double-headed endoscopic capsules, as miniaturized devices to evaluate the small bowel and colon [pan-intestinal capsule endoscopy (PCE)], makes this non-invasive procedure a disruptive concept for the management of patients with digestive disorders. This technology is expected to identify which patients will require conventional invasive endoscopic procedures (colonoscopy or balloon-assisted enteroscopy), based on the lesions detected by the capsule, i.e., those with an indication for biopsies or endoscopic treatment. The use of PCE in patients with inflammatory bowel diseases, namely Crohn's disease, as well as in patients with iron deficiency anaemia and/or overt gastrointestinal (GI) bleeding, after a non-diagnostic upper endoscopy (esophagogastroduodenoscopy), enables an effective, safe and comfortable way to identify patients with relevant lesions, who should undergo subsequent invasive endoscopic procedures. The recent development of magnetically controlled capsule endoscopy to evaluate the upper GI tract, is a further step towards the possibility of an entirely non-invasive assessment of all the segments of the digestive tract, from mouth-to-anus, meeting the expectations of the early developers of capsule endoscopy.

Abstract
BACKGROUND In patients with obscure gastrointestinal bleeding, re-examination with standard upper endoscopes by experienced physicians will identify culprit lesions in a substantial proportion of patients. A common practice is to insert an adult-sized forward-viewing endoscope into the second part of the duodenum. When the endoscope tip enters after the papilla, which is a marker for the descending part of the duodenum, it is difficult to endoscopically judge how far the duodenum has been traversed beyond the second part.
CASE SUMMARY We experienced three cases of proximal jejunal masses that were diagnosed by standard upper gastrointestinal endoscopy and confirmed with surgery. The patients visited the hospital with a history of melena; during the initial upper gastrointestinal endoscopy and colonoscopy, the bleeding site was not confirmed. Upper gastrointestinal bleeding was suspected; thus, according to guidelines, upper endoscopy was performed again. A hemorrhagic mass was discovered in the small intestine. The lesion of the first patient was thought to be located in the duodenum when considering the general insertion depth of a typical upper gastrointestinal endoscope; however, during surgery, it was confirmed that it was in the jejunum. After the first case, lesions in the second and third patients were detected at the jejunum by inserting the standard upper endoscope as deep as possible.
CONCLUSION The deep insertion of standard endoscopes is useful for the diagnosis of obscure gastrointestinal bleeding.

Abstract
Video capsule endoscopy (VCE) is a crucial adjunct to conventional endoscopy in small intestinal bleeding, with a high positive and negative predictive value. Timing is critical in VCE, with earlier deployment associated with improved diagnostic yield. VCE is also useful as a first-line diagnostic modality in the evaluation of acute gastrointestinal bleeding, with accumulating evidence demonstrating expedited VCE can increase diagnostic yield, reduce unneeded admissions, and overall improve patient care. In resource-limited settings, first-line VCE also can reduce unneeded procedures and protect staff from dangerous exposures.

Abstract
Small bowel capsule endoscopy is a minimally-invasive endoscopic investigation that is often used in clinical practice to investigate overt or occult gastrointestinal (GI) bleeding among other clinical indications. International guidance recommends small bowel capsule endoscopy as a first-line investigation to detect abnormalities in the small bowel, when gastroscopy and colonoscopy fail to identify a cause of GI bleeding. It can diagnose with accuracy abnormalities in the small bowel. However, there has been increasing evidence indicating that small bowel capsule endoscopy may also detect lesions outside the small intestine that are within the reach of conventional endoscopy and have been probably missed during prior endoscopic investigations. Such lesions vary from vascular deformities to malignancy and their detection often alters patient management, leading to further endoscopic and/or surgical interventions. The current study attempts to review all available studies in the literature and summarise their relevant findings.

Abstract
BACKGROUND Location of bleeding can present a diagnostic challenge in patients without hematemesis more so than those with hematemesis. AIM To describe endoscopic diagnostic yields in both hematemesis and non-hematemesis gastrointestinal bleeding patient populations. METHODS A retrospective analysis on a cohort of 343 consecutively identified gastrointestinal bleeding patients admitted to a tertiary care center emergency department with hematemesis and non-hematemesis over a 12-month period. Data obtained included presenting symptoms, diagnostic lesions, procedure types with diagnostic yields, and hours to diagnosis. RESULTS The hematemesis group (n = 105) took on average 15.6 h to reach a diagnosis versus 30.0 h in the non-hematemesis group (n = 231), (p = 0.005). In the non-hematemesis group, the first procedure was diagnostic only 53% of the time versus 71% in the hematemesis group (p = 0.02). 25% of patients in the non-hematemesis group required multiple procedures versus 10% in the hematemesis group (p = 0.004). Diagnostic yield for a primary esophagogastroduodenoscopy was 71% for the hematemesis group versus 50% for the non-hematemesis group (p = 0.01). Primary colonoscopies were diagnostic in 54% of patients and 12.5% as a secondary procedure in the non-hematemesis group. A primary video capsule endoscopy yielded a diagnosis in 79% of non-hematemesis patients (n = 14) and had a 70% overall diagnostic rate (n = 33). CONCLUSION Non-hematemesis gastrointestinal bleeding patients undergo multiple non-diagnostic tests and have longer times to diagnosis and then compared those with hematemesis. The high yield of video capsule endoscopy in the non-hematemesis group suggests a role for this device in this context and warrants further investigation.

Abstract
BACKGROUND Capsule endoscopy was primarily designed for the investigation of the small bowel. However, it may also identify lesions in other segments of the gastrointestinal tract. The aim of the current study was to evaluate the incidence of gastroduodenal abnormalities during small bowel capsule endoscopy and its impact on patient diagnosis and management. PATIENTS AND METHODS This study is a retrospective analysis of data from 2,217 consecutive capsule endoscopy procedures performed at a single tertiary-care center between January 2008 and February 2016. Patient baseline characteristics, gastroduodenal lesions, diagnosis and management before and after capsule endoscopy were recorded and a descriptive analysis was performed. RESULTS Two thousands and two hundred seventeen patients were finally included in the analysis. One thousand and seventy patients were male (48.2%) and the mean age was 56.1 ± 19.5 years (range: 12-93). Obscure gastrointestinal bleeding (52.3%) and inflammatory bowel disease (18.3%) were the main procedure indications. Gastroduodenal abnormalities were detected by capsule endoscopy in 696 (31.4%) of 2,217 patients. The most common types of missed gastric and duodenal lesions found were gastric erosions (35.4%), findings suggestive of chronic gastritis (22.9%), duodenal erosions (28.1%) and duodenal erythema (23.5%). This information had a clinical or diagnostic impact of 26.2% and a therapeutic impact of 15.5%. CONCLUSION Capsule endoscopy detects not only small bowel lesions but also some gastroduodenal lesions that may be overlooked during an initial gastroscopy. Therefore, all gastroduodenal images should be read during small bowel capsule endoscopy as it may provide relevant information that result in changes in patient management.

Abstract
BACKGROUND Nowadays, capsule endoscopy is the first-line procedure to assess the small bowel. During small bowel procedures, other segments of the gastrointestinal tract may be visualized. The aim of the current study was to evaluate the incidence of colonic abnormalities in patients undergoing small bowel capsule and its impact on patient management. PATIENTS AND METHODS This study is a retrospective analysis of data from 526 consecutive capsule endoscopy procedures performed at a single tertiary-care centre between 2008 and 2011. Patients with incomplete procedures were excluded from the analysis. Patient baseline characteristics, colonic lesions, diagnosis and management before and after capsule endoscopy were recorded and a descriptive analysis was performed. RESULTS Four hundred and sixty four patients were finally included in the analysis. Two hundred and ninety three patients were male (57.3%) and the mean age was 61.3 ± 20.03 years (18-86). Obscure gastrointestinal bleeding (59%) and inflammatory bowel disease (19%) were the main indications for the procedure. Colonic abnormalities were detected by capsule endoscopy in 47 (9%) of 464 patients. The most common types of missed lesions were vascular lesions (34%) and colonic ulcers (32%). This information had a clinical or diagnostic impact of 7.55% and a therapeutic impact of 6.03%. CONCLUSION All images of the colon should be evaluated during small bowel capsule endoscopy as they may provide relevant information that may result in changes in patient management.

Abstract
BACKGROUND/AIM No prior experience with video capsule endoscopy (VCE) has been published from Saudi Arabia. In this study, we aim to report the first Saudi experience with VCE. PATIENTS AND METHODS A prospective study was conducted between March 2013 and September 2017 at King Abdulaziz Medical City, Riyadh, Saudi Arabia. Eligible patients underwent VCE and their data (age, sex, indication for VCE, type of obscure gastrointestinal bleeding [OGIB: overt vs occult], VCE findings, and complications) were recorded. Approval was obtained from the institutional ethics board before the study began and all patients provided verbal and signed consent for the procedure. The procedure was performed according to the established guidelines. RESULTS During the study period, a total 103 VCE procedures were performed on 96 patients. Overall, 60 participants (62.5%) were male (mean age, 58.8 years; range, 25-97 years) and 36 (37.5%) were female (mean age, 52.8 years; range, 18-78 years). The most frequent indication for VCE was OGIB (n = 91, 88.35%; overt, n = 46, 50.55%; occult, n = 45, 49.45%). Other indications were suspected Crohn's disease (n = 4, 3.88%), suspected complicated celiac disease (n = 4, 3.88%), and unexplained chronic abdominal pain (n = 4, 3.88%). The VCE results were categorized as incomplete (n = 2, 1.94%), poor-quality (n = 7; 6.8%), normal (n = 39, 37.86%), and abnormal (n = 55, 53.4%). The completion rate was 98.06% (n = 101), and the overall diagnostic yield was 53.4%. Of the 55 patients with abnormal VCE results, 43 (78.2%) had small bowel (SB) abnormalities and 12 (21.8%) had abnormalities in the proximal or distal gut. The most frequent SB abnormalities were angiodysplasia (n = 22, 40.0%) and tumors (n = 7, 12.7%). CONCLUSION The diagnostic yield of VCE for Saudi patients with OGIB is comparable to that reported internationally; however, data for other VCE indications, including inflammatory bowel disease, are still lacking.

Abstract
BACKGROUND AND AIMS The first small-bowel video-capsule endoscopy (VCE) with 360° panoramic view has been developed recently. This new capsule has wire-free technology, 4 high-frame-rate cameras, and a long-lasting battery life. The aim of the present study was to assess the performance and safety profile of the 360° panoramic-view capsule in a large series of patients from a multicenter clinical practice setting. METHODS Consecutive patients undergoing a 360° panoramic-view capsule procedure in 7 European Institutions between January 2011 and November 2015 were included. Both technical (ie, technical failures, completion rate) and clinical (ie, indication, findings, retention rate) data were collected by means of a structured questionnaire. VCE findings were classified according to the likelihood of explaining the reason for referral: P0, low; P1, intermediate; P2, high. RESULTS Of the 172 patients (94 men; median age, 68 years; interquartile range, 53-75), 142 underwent VCE for obscure (32 overt, 110 occult) GI bleeding (OGIB), and 28 for suspected (17) or established (2) Crohn's disease (CD). Overall, 560 findings were detected; 252 were classified as P2. The overall diagnostic yield was 40.1%; 42.2% and 30.0% in patients with OGIB and CD, respectively. The rate of complete enteroscopy was 90.2%. All patients but one, who experienced capsule retention (1/172, 0.6%), excreted and retrieved the capsule. VCE failure occurred in 4 of 172 (2.3%) patients because of technical problems. CONCLUSIONS This multicenter study, conducted in the clinical practice setting and based on a large consecutive series of patients, showed that the diagnostic yield and safety profile of the 360° panoramic-view capsule are similar to those of forward-view VCEs.

Abstract
Software tools have been developed as capsule endoscopy (CE) reading aids. The suspected blood indicator (SBI) tags possible areas of haemorrhage in the gastrointestinal (GI) tract. This meta-analysis aims to investigate the diagnostic accuracy of SBI in CE. Areas covered: A systematic literature search was conducted for studies on the use of SBI in CE. Sensitivity, specificity and diagnostic odds ratio (DOR) of SBI in diagnosing GI bleeding was evaluated. 2040 patients from 16 studies underwent 2049 CE examinations. The overall sensitivity of SBI for bleeding or potentially bleeding lesions was 0.553, specificity 0.578, DOR 12.354. The sensitivity of SBI for active bleeding was 0.988, specificity 0.646, DOR 229.89. Expert commentary: Currently, SBI has limited validity in CE reading. However, in active GI bleeding, it has good sensitivity, supporting its use in the acute setting.

Abstract
BACKGROUND/AIMS Obscure gastrointestinal bleeding (OGIB) accounts for 5% of all gastrointestinal (GI) bleeding cases. Dynamic contrast-enhanced multidetector-row CT (DCE-MDCT) is not generally recommended in OGIB patients due to its low sensitivity. However, it can be used to quickly and simply diagnose OGIB according to some guidelines. The aim of this study was to evaluate the clinical efficacy of DCE-MDCT in OGIB patients. METHODS We retrospectively analyzed the medical records of 362 patients who underwent DCE-MDCT between March 2009 and January 2014. A total of 45 patients diagnosed with OGIB were included in this study. Their baseline characteristics and treatment procedure were analyzed retrospectively. The positive rates of DCE-MDCT for the detection of bleeding and associated factors were assessed. RESULTS The mean age of the patients was 59 years, and males represented 51.1%. Melena was the most common symptom (44.4%). Positive rate of DCE-MDCT findings was 20.0% (9/45). Among these patients, intraluminal contrast extravasation was found in 5 patients (55.6%) and intraluminal hematoma or mass lesions were found in 2 patients each (22.2%). Thirty nine patients (86.7%) underwent conservative management, and 6 patients (13.3%) underwent specific treatment, such as endoscopic treatment, embolization, or surgery. Patients who showed positivity in DCE-MDCT more frequently received specific treatment compared with those who were negative (44.4% vs. 5.6%, p=0.010). CONCLUSIONS Although DCE-MDCT showed a low positive rate (20.0%), positive findings of DCE-MDCT could lead to specific treatment. Positive DCE-MDCT findings play a useful role in the management of patients with OGIB.

Abstract
Gastrointestinal (GI) bleeding cases in whom source cannot be identified after conventional upper and lower GI endoscopy are defined as potential small bowel bleeding. We aimed to search for lesions in the reach of conventional endoscopy in patients to whom video capsule endoscopy (VCE) had been applied for potential small bowel bleeding. 114 patients who had VCE evaluation for potential small bowel bleeding between January 2009 and August 2015 were retrospectively evaluated. Mean age of the patients was 55 ± 17 years. Female/male ratio is 39/75. In 58 patients (50.9%) bleeding lesion could be determined. Among these 58 patients 8 patients' lesions were in the reach of conventional endoscopes. Overall these 8 patients comprised 7% of patients in whom VCE was performed for potential small bowel bleeding. Among these 8 patients 5 had colonic lesions (4 angiodysplasia, 1 ulcerated polypoid cecal lesion), 2 had gastric lesions (1 GAVE, 1 anastomotic bleeding), and 1 patient had a bleeding lesion in the duodenal bulbus. Although capsule endoscopy is usually performed for potential small bowel bleeding gastroenterologists should always keep in mind that these patients may be suffering from bleeding from non-small bowel segments and should carefully review images captured from non-small bowel areas.

Abstract
BACKGROUND AND STUDY AIMS Delayed gastric emptying is a significant factor in incomplete small bowel capsule examinations. Gastric transit could be hastened by external magnetic control of the capsule. We studied the feasibility of this approach to improve capsule endoscopy completion rates. PATIENTS AND METHODS Prospective, single-center, randomized controlled trial involving 122 patients attending for small bowel capsule endoscopy using MiroCam Navi. Patients were randomized to either the control group (mobilisation for 30 minutes after capsule ingestion, followed by intramuscular metoclopramide 10 mg if the capsule failed to enter the small bowel) or the intervention group (1000 mL of water prior to capsule ingestion, followed by positional change and magnetic steering). Outcome measures were capsule endoscopy completion rate, gastric clarity and distention, relationship of body habitus to capsule endoscopy completion rate (CECR), and patient comfort scores. RESULTS 122 patients were recruited (61 each to the control and intervention groups: mean age 49 years [range 21 - 85], 61 females). There was no significant difference in CECR between the two groups (P = 0.39). Time to first pyloric image was significantly shorter in the intervention group (P = 0.03) but there was no difference in gastric transit times (P = 0.12), suggesting that magnetic control hastens capsular transit to the gastric antrum but does not influence duodenal passage. Gastric clarity and distention were significantly better in the intervention group (P < 0.0001 and P < 0.0001 respectively). CONCLUSIONS Magnetic steering of a small bowel capsule is unable to overcome pyloric contractions to enhance gastric emptying and improve capsule endoscope completion rate. Excellent mucosal visualisation within the gastric cavity suggests this technique could be harnessed for capsule examination of the stomach.

Abstract
INTRODUCTION Obscure gastrointestinal bleeding (OGIB) is defined as bleeding from the gastrointestinal tract with no obvious cause after assessment with upper and lower gastrointestinal endoscopy. In these cases, the source is suspected to be in the small bowel. Obscure bleeding can be occult or overt. The aim of this study was to analyze the clinical and analytical characteristics and findings on capsule endoscopy in patients with OGIB and to determine the factors related to the detection of lesions in both forms of presentation. METHODS We performed a retrospective study of capsule endoscopies carried out between November 2009 and November 2012 for OGIB. RESULTS We analyzed 284 capsule endoscopies in 272 patients. Initially, 12 procedures could not be evaluated and were repeated. A total of 272 procedures were finally included in the analysis. The results of 114 (41.9%) capsule endoscopies were normal. Compared with patients with occult OGIB, those with overt OGIB were significantly older (70.2 vs. 67.5 years; p = 0.04), consumed more NSAID (24.2% vs. 11.9%; p = 0.01), had higher hemoglobin levels (9.3 vs. 10.4; p < 0,001) and more frequently required transfusion (64.5% vs 32.2%; p < 0.001). No differences were found between the two forms of presentation in the detection of canker sores-ulcers and polyps-masses. Vascular lesions were more frequently detected in overt than in occult OGIB (40.3% vs. 25.7%, respectively), (p < 0.05). When the total number of diagnoses carried out by capsule endoscopy was analyzed, no differences were found in diagnostic yield between overt OGIB (57%) and occult OGIB (54%), (p = 0.6). In overt OGIB, multivariate analysis showed that the variables that significantly predicted the detection of lesions on capsule endoscopy were consumption of medication NSAID (OR 2.75; p = 0.01), antiplatelets and anticoagulants (OR 2.64; p = 0.03) and analytical data hemoglobin (OR 3.23; p < 0.001) and INR (OR 1.8; p = 0.02). In occult OGIB, multivariate analysis showed that the factors significantly related to the detection of lesions on endoscopy were age (OR 1.9; p = 0.04) and NSAID consumption (OR 2.1; p = 0.01). CONCLUSIONS Capsule endoscopy is essential in the assessment of OGIB. Although the diagnostic yield was similar in both forms of presentation, vascular lesions were more frequently detected in overt OGIB. The diagnostic yield of capsule endoscopy could be optimized by taking into account the form of presentation (overt vs. occult) and certain clinical and analytic data (age, drug consumption, hemoglobin).

Abstract
Obscure gastrointestinal bleeding (OGIB) refers to gastrointestinal (GI) bleeding of unclear origin that persists or recurs after negative findings on esophagogastroduodenoscopy and colonoscopy. OGIB accounts for approximately 5% of all types of GI bleeding. More than 80% of OGIB cases originate in the small bowel. The ability to detect OGIB in the small bowel has significantly advanced and been revolutionized since the introduction of the capsule endoscopy and double-balloon enteroscopy techniques in 2000 and 2001, respectively. With these new methods for small-bowel evaluation, new guidelines have been proposed for the diagnosis and management of OGIB. However, some issues remain unsolved. The purpose of this article is to review the various modalities used for evaluating OGIB, including capsule endoscopy and double-balloon enteroscopy, and to help guide clinicians in their decisions on which modality will be the most effective.

Abstract
BACKGROUND To date, there are no large studies on videocapsule endoscopy in systemic sclerosis (SSc). Consequently, the prevalence and features of gastrointestinal mucosal abnormalities in SSc have not been determined. AIMS To determine both prevalence and characteristics of gastrointestinal mucosal abnormalities in unselected patients with SSc, using videocapsule endoscopy. To predict which SSc patients are at risk of developing potentially bleeding gastrointestinal vascular mucosal abnormalities. METHODS Videocapsule endoscopy was performed on 50 patients with SSc. RESULTS Prevalence of gastrointestinal mucosal abnormalities was 52%. Potentially bleeding vascular mucosal lesions were predominant, including: watermelon stomach (34.6%), gastric and/or small intestinal telangiectasia (26.9%) and gastric and/or small intestinal angiodysplasia (38.5%). SSc patients with gastrointestinal vascular mucosal lesions more often exhibited: limited cutaneous SSc (P = 0.06), digital ulcers (P = 0.05), higher score of nailfold videocapillaroscopy (P = 0.0009), anaemia (P = 0.02), lower levels of ferritin (P < 0.0001) and anti-centromere antibody. CONCLUSIONS Our study identifies a high frequency of gastrointestinal mucosal abnormalities in SSc, with a marked predominance of vascular mucosal damage. Furthermore, our study shows a strong correlation between gastrointestinal vascular mucosal lesions and presence of severe extra-digestive vasculopathy (digital ulcers and higher nailfold videocapillaroscopy scores). This latter supports the theory that SSc-related diffuse vasculopathy is responsible for both cutaneous and digestive vascular lesions. Therefore, we suggest that nailfold videocapillaroscopy may be a helpful test for managing SSc patients. In fact, nailfold videocapillaroscopy score should be calculated routinely, as it may result in identification of SSc patients at higher risk of developing potentially bleeding gastrointestinal vascular mucosal lesions.

Abstract
AIM: To investigate the incidence of non-small-bowel abnormalities in patients referred for small bowel capsule endoscopy, this single center study was performed.
METHODS: Small bowel capsule endoscopy is an accepted technique to investigate obscure gastrointestinal bleeding. This is defined as bleeding from the digestive tract that persists or recurs without an obvious etiology after a normal gastroduodenoscopy and colonoscopy. Nevertheless, capsule endoscopy sometimes reveals findings outside the small bowel, i.e., within reach of conventional endoscopes. In this retrospective single center study, 595 patients undergoing capsule endoscopy between 2003 and 2009 were studied. The incidence of non-small bowel abnormalities was defined as visible abnormalities detected by capsule endoscopy that are located within reach of conventional endoscopes.
RESULTS: In 595 patients, referred for obscure gastrointestinal bleeding or for suspected Crohn’s disease, abnormalities were found in 306 (51.4%). Of these 306 patients, 85 (27.7%) had abnormalities within reach of conventional endoscopes; 63 had abnormalities apparently overlooked at previous conventional endoscopies, 10 patients had not undergone upper and lower endoscopy prior to capsule endoscopy and 12 had abnormalities that were already known prior to capsule endoscopy. The most common type of missed lesions were vascular lesions (n = 47). Non-small-bowel abnormalities were located in the stomach (n = 15), proximal small bowel (n = 22), terminal ileum (n = 21), colon (n = 19) or at other or multiple locations (n = 8). Ten patients with abnormal findings in the terminal ileum had not undergone examination of the ileum during colonoscopy.
CONCLUSION: A significant proportion of patients undergoing small bowel capsule endoscopy had lesions within reach of conventional endoscopes, indicating that capsule endoscopy was unnecessarily performed.

Abstract
BACKGROUND ESO-2 video capsule endoscopy provides images of the oesophageal mucosa and continues to transmit gastric, and often small bowel images, for up to 30 min. This study compares ESO capsule endoscopy capsule oesophago-gastro-duodenoscopy (Cap-OGD) with conventional endoscopy (OGD). METHODS 50 outpatients with uncomplicated dyspepsia underwent Cap-OGD followed by OGD which was recorded on DVD. Cap-OGD and OGD were each reported independently by two gastroenterologists. A benchmark report was also produced by two gastroenterologists viewing both Cap-OGD and OGD on side-by-side monitors. Major findings included large hiatus hernia, Barrett's oesophagus, oesophagitis, erosive gastritis, tumour and ulceration. Minor findings included histologically-proven superficial gastritis, pouting gastric folds and fundic gland polyps. A questionnaire assessed the patient experience. RESULTS 49 patients completed the study. In 61%, Cap-OGD transmitted in the duodenum. In the benchmark study, all the major OGD findings were observed on Cap-OGD. Cap-OGD revealed fewer minor findings. When reported independently, Cap-OGD and OGD reports indicated differences in interpretation most marked between the capsule readers with or without previous ESO-2 experience. Patients expressed a clear preference for Cap-OGD. CONCLUSIONS When compared side-by-side, all the major findings on OGD are seen on Cap-OGD while there is under-reporting of minor findings. Previous experience of ESO-2 capsule reporting improves reading accuracy and indicates the need for training. This pilot study provides a backdrop to explore the possible role of Cap-OGD, especially where patients are reluctant to undergo conventional OGD or where there is risk of prion contamination of the endoscope.

Abstract
Gastric antral vascular ectasia (GAVE) has been recognized as one of the important causes of occult and obscure gastrointestinal bleeding. The diagnosis is typically made based on the characteristic endoscopic features, including longitudinal row of flat, reddish stripes radiating from the pylorus into the antrum that resemble the stripes on a watermelon. These appearances, however, can easily be misinterpreted as moderate to severe gastritis. Although it is believed that capsule endoscopy (CE) is not helpful for the study of the stomach with its large lumen, GAVE can be more likely to be detected at CE rather than conventional endoscopy. CE can be regarded as “physiologic” endoscopy, without the need for gastric inflation and subsequent compression of the vasculature. The blood flow of the ecstatic vessels may be diminished in an inflated stomach. Therefore, GAVE may be prominent in CE. We herein describe a case of active bleeding from GAVE detected by CE and would like to emphasize a possibility that CE can improve diagnostic yields for GAVE.

Abstract
The diagnosis and management of patients with obscure gastrointestinal bleeding are often long and challenging processes. Over the last 10 years the introduction in clinical practice of new diagnostic and therapeutic procedures (i.e. Capsule Endoscopy, Computed Tomographic Enterography, Magnetic Resonance Enterography, and Device Assisted Enteroscopy) has revolutionized the diagnostic/therapeutic work-up of these patients. Based on evidence published in the last 10 years, international scientific societies have proposed new practice guidelines for the management of obscure gastrointestinal bleeding, which include these techniques. However, although these algorithms (the most recent ones are endorsed by the American Society for Gastrointestinal Endoscopy - ASGE) allow the management of the large majority of patients, some issues still remain unsolved. The present paper reports the results of the discussion, based on the literature published up to September 2011, among a panel of experts and gastroenterologists, working with Capsule Endoscopy and with Device Assisted Enteroscopy, attending the 6th annual meeting of the Italian Club for Capsule Endoscopy and Enteroscopy. Eight unresolved issues were selected: each of them is presented as a "Burning question" and the "Answer" is the strategy proposed to manage it, according to both the available evidence and the discussion among participants.

Abstract
BACKGROUND AND AIM Little is known about the causes of overt obscure gastrointestinal bleeding (OGIB) in patients using anti-thrombotic therapy. We aimed to describe video capsule endoscopy (VCE) findings and to identify factors associated with positive findings in these patients. METHODS We carried out a retrospective study of 56 patients who underwent VCE for evaluation of previous overt OGIB during anti-thrombotic therapy. VCE studies were re-evaluated by a gastroenterologist blinded to clinical details. Clinical data included in the multivariate analysis were sex, age, indication for and type of anti-thrombotic therapy, hemodynamic instability on admission, type of blood loss, hemoglobin on admission, use of a proton pump inhibitor, NSAID use, time between bleeding episodes and VCE, and whether or not anti-thrombotic therapy was resumed before the VCE study. RESULTS A probable cause for gastrointestinal bleeding was identified in 28 (50%) of the 56 studies. Angiodysplasia was found in 19 patients. Twenty-two studies showed a possible cause in the small bowel. Multivariate logistic regression analysis showed that reinstitution of anti-thrombotic therapy before VCE was carried out was the only independent predictor of positive VCE findings (OR: 8.61, 95% CI: 1.20-60.42, P=0.032). CONCLUSIONS Small intestinal angiodysplasia was the most common cause for overt OGIB. Reinstitution of withdrawn anti-thrombotic drugs before the VCE examination was carried out was associated with positive VCE findings in multivariate analysis.

Abstract
BACKGROUND The primary aim was to assess the value of immunochemical and guaiac fecal occult blood test (FOBT) as a screening test before capsule endoscopy (CE) in the setting of obscure gastrointestinal bleeding (OGIB). METHODS A prospective study from the St Vincent's Hospital, a tertiary referral hospital in Melbourne, Australia. Sixty-eight patients referred for CE to investigate OGIB underwent two immunochemical/guaiac FOBTs within 2 weeks preceding CE. The correlation between a positive FOBT before CE and clinically significant findings (CSFs) on CE was assessed. RESULTS Thirty of 68 (44%) patients with OGIB had significant findings on CE. The accuracy of a combined immunochemical and guaiac FOBT for predicting clinically significant findings on CE was 62% [95% confidence interval (CI): 0.50-0.72]. The sensitivity and specificity were low at 63% (95% CI: 0.50-0.75) and 61% (95% CI: 0.50-0.70), respectively. CONCLUSION FOBT has low accuracy as a screening test before CE and thus cannot be recommended for this purpose.

Bleeding lesions within reach of conventional endoscopy in capsule endoscopy examinations for obscure gastrointestinal bleeding: is repeating endoscopy economically feasible? Dig Dis Sci 2011; 56:1763-8.

Abstract
BACKGROUND Most tertiary gastroenterology centers currently offer an open-access capsule endoscopy (CE) service, including patients with obscure gastrointestinal bleeding. However, CE may identify lesions missed by conventional endoscopy. AIMS To determine the incidence of bleeding lesions missed by the preceding gastroscopy/colonoscopy that were revealed by CE and compare potential differences in the rate of identifying such lesions in patients that we investigated as opposed to those investigated elsewhere. METHODS We prospectively reviewed data from patients subjected to CE for obscure bleeding. We analyzed all cases where a source of bleeding was located in the stomach, duodenum, or colon. RESULTS A total of 317 consecutive patients were subjected to CE for obscure gastrointestinal bleeding within 28 months. Prior to CE examination, 174 patients had gastroscopy and colonoscopy in our institutions and 143 were referrals, all with negative endoscopic investigation. We identified 11 (3.5%) cases where the source of bleeding was found in the stomach (n = 4) or the cecum (n = 7). There was a significant difference of extra small intestinal lesions diagnosed by CE between referrals (9/143, 6.3%) and endoscopic investigation performed in our institutions (2/174, 1.15%), (p = 0.026). The estimated cost of re-endoscoping in our institution all CE referrals would be 50,050 euro (143 patients × 350 euro), to avoid unnecessary CE examinations (9 patients × 600 euro = 5,400 euro). CONCLUSIONS Reading the whole CE video is important, because small-bowel CE may identify lesions responsible for obscure bleeding missed by the preceding gastroscopy and colonoscopy. Repeating conventional endoscopy by experts before CE is not a cost-effective approach.

Abstract
PURPOSE Capsule endoscopy by enabling direct visualization of small bowel mucosa has conquered the last frontier of diagnostic endoscopy. However, its ability to simultaneously detect colonic lesions has not been evaluated. This study was done to evaluate frequency of detection of colonic abnormalities in patients undergoing small bowel capsule endoscopy and its impact on the clinical management. PATIENTS AND METHODS Eighty-seven patients (60 males; mean age: 51.2 ± 18.6 years) who had obscure gastrointestinal bleeding or unexplained abdominal pain or unexplained diarrhea underwent capsule endoscopy. The demographic data and capsule endoscopy findings were retrospectively evaluated. RESULTS Capsule endoscopy was normal in 26 (29.8%) patients and small bowel abnormalities were noted in 49 (56.3%) patients. Capsule endoscope did not reach the cecum during the battery life period of the capsule in five (5.7%) patients. Colonic abnormalities were noted in eight (9.1%) patients. These included cecal angiodysplasia (four), cecal carcinoma (one), transverse colon polyp (one), sigmoid colon ulcerations with histological diagnosis of Crohn's colitis (one), and cecal ulcers with final diagnosis of amebic colitis (one). CONCLUSION The colon should also be carefully evaluated in patients undergoing small bowel capsule endoscopy as significant lesions can be detected that helps in appropriate management.

Abstract
This is one of a series of statements discussing the use of GI endoscopy in common clinical situations. The Standards of Practice Committee of the American Society for Gastrointestinal Endoscopy (ASGE) prepared this text. In preparing this guideline, we performed a search of the medical literature by using PubMed. Additional references were obtained from the bibliographies of the identified articles and from recommendations of expert consultants. Guidelines for appropriate use of endoscopy are based on a critical review of the available data and expert consensus at the time the guidelines were drafted. Further controlled clinical studies may be needed to clarify aspects of this guideline. This guideline may be revised as necessary to account for changes in technology, new data, or other aspects of clinical practice. The recommendations are based on reviewed studies and are graded on the strength of the supporting evidence (Table 1).(1) The strength of individual recommendations is based both upon the aggregate evidence quality and an assessment of the anticipated benefits and harms. Weaker recommendations are indicated by phrases such as "we suggest," whereas stronger recommendations are typically stated as "we recommend." This guideline is intended to be an educational device to provide information that may assist endoscopists in providing care to patients. This guideline is not a rule and should not be construed as establishing a legal standard of care or as encouraging, advocating, requiring, or discouraging any particular treatment. Clinical decisions in any particular case involve a complex analysis of the patient's condition and available courses of action. Therefore, clinical considerations may lead an endoscopist to take a course of action that varies from these guidelines.

Abstract
AIM: To report the incidence of non-small-bowel bleeding pathologies encountered during double-balloon enteroscopy (DBE) procedures and to analyse their significance.
METHODS: A retrospective study of a prospective DBE database conducted in a tertiary-referral center was conducted. A total of 179 patients with obscure gastrointestinal bleeding (OGIB) referred for DBE from June 2004 to November 2008 were analysed looking for the incidence of non-small-bowel lesions (NSBLs; all and newly diagnosed) encountered during DBE.
RESULTS: There were 228 (150 antegrade and 78 retrograde) DBE procedures performed in 179 patients. The mean number of DBE procedures was 1.27 per patient. The mean age (SD) of the patients was 62 ± 16 years old. There were 94 females (52.5%). The positive yield for a bleeding lesion was 65.9%. Of the 179 patients, 44 (24.6%) had NSBLs (19 of them had dual pathology with small-bowel lesions and NSBLs); 27 (15.1%) had lesions not detected by previous endoscopies. The most common type of missed lesions were vascular lesions.
CONCLUSION: A significant proportion of patients (24.6%) had lesions within reach of conventional endoscopy. Careful repeat examination with gastroscopy and colonoscopy might be required.

Abstract
AIM To evaluate the Z-line visualization by the PillCam SB2 using three different ingestion protocols. METHODS Ninety consecutive patients undergoing small bowel capsule endoscopy (SBCE) between January and May 2008 were included in the study. They swallowed the capsule in the standing (Group A = 30), supine (Group B = 30) and right supine positions (Group C = 30). Baseline patient characteristics, difficulties in capsule ingestion, esophageal transit times (ETT) and Z-line visualization were noted. RESULTS No significant differences were found between the groups with regard to baseline patient characteristics, ingestion difficulties and complete SB examinations (P > 0.05). At least 1 frame of the Z-line was detected in 15.8%, 46.7% and 90% of patients in groups A, B and C, respectively (P < 0.001). The average number of Z-line images was 0.21 +/- 0.53, 3.23 +/- 6.59 and 5.53 +/- 7.55 and the mean % of the Z-line detected was 71.3, 25.1 and 8.3, in groups A, B and C, respectively (both P < 0.001). ETT times were longer in the supine group followed by the right supine and the standing groups (median of 237 s vs 64 s and 39 s, respectively; P < 0.001). CONCLUSION Z-line visualization in patients undergoing SBCE can be accurately achieved in most cases when the capsule is swallowed in the right supine position.

Abstract
Capsule endoscopy and balloon-assisted enteroscopy, have revolutionized our approach to the diagnosis and management of patients with obscure gastrointestinal bleeding, largely replacing intraoperative enteroscopy and conventional barium studies. Despite its limitations, capsule endoscopy may well be the most reasonable initial diagnostic strategy to evaluate most patients with obscure gastrointestinal bleeding, leaving balloon-assisted enteroscopy in reserve as a complementary tool. This article reviews the data on enteroscopy, with particular emphasis on the use of capsule endoscopy and balloon-assisted enteroscopy for the diagnosis and management of patients with obscure gastrointestinal bleeding.

Abstract
BACKGROUND AND AIM Medicare reimbursement for capsule endoscopy for the investigation of obscure gastrointestinal bleeding in Australia requires endoscopy and colonoscopy to have been performed within 6 months. This study aims to determine the diagnostic yield of repeating these procedures when they had been non-diagnostic more than 6 months earlier. METHODS Of 198 consecutive patients who were referred for the investigation of obscure gastrointestinal bleeding, 50 underwent repeat endoscopy and colonoscopy solely to enable reimbursement (35 females and 15 males; mean age 59.4 [range: 21-82] years). The average duration of obscure bleeding was 50.16 (range: 9-214) months. The mean number of prior endoscopies was 3 (median: 2) and 2.8 colonoscopies (median: 2). The most recent endoscopy had been performed 18.9 (median: 14; range: 7-56) months, and for colonoscopy, 19.1 (median 14; range 8-51) months earlier. RESULTS A probable cause of bleeding was found at endoscopy in two patients: gastric antral vascular ectasia (1) and benign gastric ulcer (1). Colonoscopy did not reveal a source of bleeding in any patient. Capsule endoscopy was performed in 47 patients. Twenty four (51%) had a probable bleeding source identified, and another five (11%) a possible source. These included angioectasia (17 patients), mass lesion (2), non-steroidal anti-inflammatory drug enteropathy (2), Cameron's erosions (2), and Crohn's disease (1). Four patients undergoing repeat capsule endoscopy had a probable bleeding source detected. CONCLUSION The yield of repeat endoscopy and colonoscopy immediately prior to capsule endoscopy is low when these procedures have previously been non-diagnostic. Such an approach is also not cost-effective.

Abstract
BACKGROUND To date, there are no large endoscopic studies in systemic sclerosis (SSc), and both prevalence and characteristics of watermelon stomach in SSc have not been determined. AIMS To determine the prevalence, clinical presentation, endoscopic appearance, therapy success and long-term outcome in SSc patients with watermelon stomach and make predictions about which SSc patients are at risk for watermelon stomach. Patients and methods From 1990 to 2008, 264 patients were seen for evaluation of SSc. Data were collected as regards patients' characteristics, time of watermelon stomach onset, features, therapy and outcome of watermelon stomach. RESULTS Fifteen SSc patients (5.7%) exhibited watermelon stomach. SSc onset preceded watermelon stomach manifestations in 13 patients (86.7%). Most patients (86.7%) presented with iron-deficiency anaemia, two other patients experienced gastrointestinal haemorrhage. Gastroscopy disclosed typical 'watermelon stomach' characterized by prominent, erythematous stripes, radiating in a spoke-like fashion from the antrum to the pylorus. All patients received conservative therapy; because of deterioration of watermelon stomach, eight patients (53.3%) underwent endoscopic procedures. During follow-up, five patients (33.3%) exhibited recurrences of watermelon stomach. CONCLUSIONS Our series indicates that watermelon stomach should be considered when unexplained iron-deficiency anaemia occurs in SSc patients. Moreover, because watermelon stomach may be the first manifestation of SSc, patients with unexplained watermelon stomach should systematically undergo physical examination and autoantibody testing to detect the underlying SSc.

Abstract
GOALS To evaluate the diagnostic yield of push enteroscopy in relation to indication and compare the yield in patients who had capsule endoscopy followed by push enteroscopy against capsule endoscopy naive patients. BACKGROUND With the advent of capsule endoscopy the role of push enteroscopy needs to be reevaluated. STUDY Patients who underwent push enteroscopy from January 2002 to May 2006 were included. RESULTS One hundred fifty-five patients underwent push enteroscopy: 93 females, average age 55 years. There were 74 cases where both push enteroscopy (PE) and capsule endoscopy (CE) were performed. Indications for PE were iron deficiency anemia (n=51), overt bleeding (n=31), suspected celiac disease (n=32), refractory celiac disease (n=19), assessment for Crohn's disease (n=10), and miscellaneous (n=12). In 148 patients, an average length of 70 cm of small bowel was examined (range 30 to 130 cm). PE was unsuccessful in 7 patients due to anatomic strictures or patient distress. The overall diagnostic yield was 30% with the highest yield in overt bleeding when compared with other subgroups (P<0.001). Nine percent of lesions were within the reach of a standard endoscope. Comparison of the diagnostic yield in patients who had CE followed by PE against CE naive patients was 41% versus 47%, respectively (P<1). There were no cases where push enteroscopy recognized a lesion that had not been already detected by capsule endoscopy. CONCLUSIONS Push enteroscopy has the greatest diagnostic yield in patients with overt bleeding when compared with other referral indications. PE should be used as an adjuvant to CE for therapeutic intervention.

Abstract
Our objective was to evaluate the diagnostic yield and effect of capsule endoscopy on patient management in routine clinical practice. Three hundred examinations were performed (176 females; mean age, 51 years), with a median follow-up of 17 months. Indications included overt bleeding (n=55), anemia (n=104), suspected Crohn's disease (n=68), celiac disease (n=35), suspected functional symptoms (n=23), polyposis (n=5), and miscellaneous (n=10). The overall diagnostic yield was 39%, but it was notably higher in overt bleeders, 66%, compared to 46% in the anemia group (P<0.025), 32% in the suspected Crohn's group (P<0.001), and 17% in the functional group (P<0.001). As a result of capsule endoscopy, management was altered in 26% of patients. This study shows that capsule endoscopy has both a high diagnostic yield and an impact on subsequent patient management. These data further support the role of capsule endoscopy in routine clinical practice.

Abstract
BACKGROUND Capsule endoscopy has involved a significant advance in techniques for imaging of the small bowel. Its most frequent indication is for studying patients with obscure gastrointestinal bleeding (OGIB). Small bowel tumors are infrequent, representing only 1% to 3% of all malignant gastrointestinal tumors. This study aimed to assess retrospectively the occurrence and characteristics of tumoral pathology diagnosed by means of capsule endoscopy in patients with OGIB. METHODS A retrospective review analyzed the first 320 patients submitted to capsule endoscopy because of OGIB (166 with obscure overt bleeding and 154 with obscure occult bleeding) at a single center. The patients with a tumor diagnosis were analyzed in terms of incidence, characteristics, and treatment of OGIB pathology. RESULTS Tumor incidence was of 7.18% (23/320), with 65.2% of the cases supported with histologic confirmation (15/23). Obscure overt bleeding was the most frequent form of presentation, with the jejunum as the most frequent location (65.2%). For 16 patients, an intervention was conducted with a healing intent. Capsule endoscopy allowed the diagnosis of two cecal adenocarcinomas missed by colonoscopy. CONCLUSIONS Small bowel tumors are not an infrequent cause of OGIB. Capsule endoscopy, even if it does not allow determination of the benign or malignant nature or the histologic type of the tumor, is a useful tool for the diagnosis and early management of these tumors.

Abstract
Background: Capsule endoscopy (CE) is a new diagnostic tool for the study of patients with suspected small bowel pathology. The aim of the study was to clarify the usefulness of CE in the group of patients with obscure (overt / occult) gastrointestinal (GI) bleeding. Patients and methods: Thirty patients (14 men, 16 women, mean age 50 years, range 9 -79 years) were enrolled in the study. All of them undergone non-diagnostic esophagogastroduodenoscopy, colonoscopy and barium follow-through of the small bowel. All patients underwent capsule endoscopy. Fourteen patients had overt and sixteen occult bleeding. The single senior endoscopist interpreted CE findings in an unblended manner. Results: CE identified a source of bleeding in 14/30 patients (46,6 %). Lesions identified were: tumors in five pts, vascular lesions, Crohn's disease and Meckel's diverticulum in two pts and fresh bleeding, segmental celiac disease and colonic diverticulosis in one patient each. CE identified a source of bleeding in 9/14 (64,3%) of patients with ongoing overt bleeding and in only 5/16 (31,3%) of patients with occult bleeding. The positive suspicious findings were seen in 6/30 (20%) of patients (2/14 with overt bleeding and 4/16 with occult bleeding. In 3/14 (21,4%) with overt and 7/16 (43,7%) with occult bleeding findings on CE were negative. All patients with negative findings on follow-up remained asymptomatic for one year.
