Abstract
Despite its rarity in the general population, small bowel adenocarcinoma risk is increased in individuals with hereditary colorectal cancer syndromes (HCCS). In the last decade, the advent of capsule endoscopy and device-assisted balloon enteroscopy procedures in patients with HCCS have allowed to investigate the whole small bowel, increasing the diagnostic yield of small bowel tumor. Nonetheless, there is a significant variability in the international guideline recommendations. The aim of this review is to provide an update on surveillance of small bowel in HCCS and to identify the key points for the clinical management of these patients.

Abstract
AIM: To analyze the characteristics of the small intestine of patients with gastrointestinal disorders by capsule endoscopy.
METHODS: Fifty-three patients who underwent MiroCam capsule endoscopy from August 2010 to August 2011 were included in the study. According to clinical data, the patients were classified as having obscure gastrointestinal bleeding, suspected functional gastrointestinal disease, abdominal pain, diarrhea, and abdominal distension. The characteristics of the normal or abnormal small bowel were analyzed.
RESULTS: Of 53 patients, one failed capsule endoscopy due to the absence of signal, and one could not successfully complete the examination procedure for personal reason. The capsule endoscope reached the colon in the remaining 51 cases (96.22%). The average time for the passage of the capsule endoscope to the stomach and small intestine is 69.78 and 513.25 min, respectively. Capsule endoscopy revealed abnormal changes in 48 cases, and the positive rate is 90.57%. For all 51 patients with suspected small bowel disease, the overall positive diagnosis rate of intestinal lesions was 92.15% (47/51), and that of jejunal and ileal lesions was 52.94%, including 12 cases of non-specific inflammation (1 patient diagnosed with Crohn's disease), 3 cases of polyps, 3 cases of unknown mass, 1 case of hyperplasia of lymphoid follicles, 7 cases of intestinal lymphangiectasia, and 1 case of hookworm disease. In addition, 1 case of of reflux esophagitis, 26 cases of chronic gastritis, 7 cases of erosive gastritis, 3 cases of stomach polyps, 5 cases of colon polyps, 3 cases of colitis, and 2 cases of colon melanosis were found. Capsules were removed from the body naturally, and no complications such as obstruction occurred.
CONCLUSION: MiroCam capsule endoscopy is a safe and non-invasive means of revealing small intestinal lesions.

Abstract
Capsule endoscopy (CE) has been increasingly used for diagnosing disease of the small bowel. It is an attractive technique for assessing celiac disease (CD) because it is noninvasive and provides a close and magnified view of the mucosa of the entire small bowel. The aim of this paper is to update the current data on the use of CE for diagnosing villous atrophy and complications of CD.

Abstract
Capsule endoscopy has been widely used since it was approved by the Food & Drug Administration in the USA in 2001. It plays an important role in the investigation of obscure gastrointestinal bleeding, Crohn's disease and complications of coeliac disease, and surveillance of polyposis syndromes in adults. Despite a lag in its use in paediatrics, capsule endoscopy offers an accurate and effective means of investigating the small bowel in children. It has opened up new horizons and provided a noninvasive approach to identify occult lesions in the small bowel. This article reviews the recent advance in clinical applications of capsule endoscopy.

Abstract
The hereditary polyposis syndromes and non-polyposis colorectal carcinoma have been considered as scarcely occurring but inheritable dominant autosomal syndromes. The increasing risk of small bowel carcinoma and prevention of obstruction and intussusception have been making frequent and acute surgical interventions unavoidably led to the necessity of screening and surveillance the patients. Earlier the diagnosis of these symptoms was difficult to establish because traditional radiological methods have a low yield for small polyps. Furthermore, small bowel is only partially accessible with traditional endoscopic techniques such as upper endoscopy, colonoscopy and push-enteroscopy. The "wireless" capsule endoscopy has opened the way then for the non-invasive and painless test of the entire small intestine. - Test results have been cumulated to justify the efficiency and safety of capsule endoscopy concerning the syndromes above. This method can be applied safely even consequently to repeatedly performed surgical interventions by low risk of capsule retention. As the results compared of the diagnosed familial adenomatous polyposis and of Peutz-Jeghers syndrome reflect on capsule endoscopy, its diagnostic sensitiveness is stated as significantly higher than the Barium-contrast X-Ray and MR-enterography. Nevertheless, determination of size and location of polyps has become more problematic when evaluating the test results.

Abstract
GOALS To assess the effectiveness, safety, and clinical use of capsule endoscopy (CE) in the diagnosis of small bowel diseases. STUDY Systematic review carried out in the main electronic databases, including MEDLINE, EMBASE, and COCHRANE. Papers were selected independently by the 2 researchers and the quality was determined using a purpose-designed scale. RESULTS A total of 9 systematic reviews and 28 original papers were included [11 assessed obscure gastrointestinal bleeding, 9 Crohn's disease (CD), and 4 hereditary polyposis syndromes]. The diagnostic yield of CE for the diagnosis of obscure gastrointestinal bleeding ranged from 39% to 77%. The diagnostic yield of push enteroscopy was lower than 40% in all but 1 study. CE detected suggestive findings in 19% to 71% of patients with suspected CD, whereas radiologic techniques did so in only 0% to 37% of the cases. In patients with suspected recurrence, detection with these techniques was 58% to 81% and 19% to 67%, respectively. Endoscopic capsule detected a greater number of polyps in patients with polyposis syndromes but other techniques allowed for better localization. CONCLUSIONS Although CE occupies a preferential place in the diagnosis of gastrointestinal bleeding and CD; there is insufficient evidence to establish whether it could be used as a first line diagnostic test. The evidence is insufficient to ascertain this technique's usefulness in small bowel disorders other than obscure bleeding or CD.

Abstract
PURPOSE OF REVIEW The small bowel has been a technically difficult area to examine. Indirect modalities such as barium follow-through have the disadvantage of attendant radiation exposure. Capsule endoscopy, a novel wireless method of investigation of the small bowel, has acquired an important role in both adult and paediatric medicine. RECENT FINDINGS The clinical utility of capsule endoscopy has rapidly expanded since its approval by the Food & Drug Administration in the USA in 2001. It has developed an established role in adults, in the investigation of obscure gastrointestinal bleeding, small bowel Crohn's disease, complications of coeliac disease and surveillance of polyposis syndromes. Despite a lag in its use in paediatrics, capsule endoscopy offers an accurate and effective means of investigating the small bowel in children. It has opened up new horizons and permitted a noninvasive approach to identifying occult lesions in the small bowel of children when conventional imaging has been unhelpful. SUMMARY This review appraises the current literature to define the clinical indications and practical aspects of capsule endoscopy that are of interest to the paediatrician.

Abstract
OBJECTIVES Duodenal biopsy is the current gold standard for diagnosis of celiac disease. Videocapsule endoscopy examines the entire small bowel and allows visualization of mucosal villi. We evaluated the potential of videocapsule endoscopy in assessing the severity and extent of mucosal changes in patients with suspected celiac disease. METHODS Consecutive patients with signs/symptoms suggesting celiac disease and positive anti-gliadin and/or anti-endomysial and/or anti-tissue transglutaminase antibodies underwent upper gastrointestinal endoscopy and videocapsule endoscopy. Duodenal biopsies were classified according to modified Marsh's criteria. Capsule findings were evaluated for the presence of lesions compatible with celiac disease (scalloping of duodenal folds, fissures, flat mucosa, and mosaic appearance). RESULTS Forty-three patients were studied. Duodenal histology was normal in 11 and compatible with celiac disease in 32. Using duodenal histology as the gold standard, the performance characteristics of capsule endoscopy for the diagnosis of celiac disease were: sensitivity 87.5% (95% CI 76.1-98.9%), specificity 90.9% (95% CI 81.0-100%), positive predictive value 96.5% (95% CI 90.1-100%), negative predictive value 71.4% (95% CI 55.8-87%), positive and negative likelihood ratios 9.6 and 0.14, respectively. Eighteen patients had mucosal changes extending beyond the duodenum, involving the entire small bowel in three. These patients tended to have more severe symptoms, but the difference was not statistically significant. Interobserver agreement for the diagnosis of celiac disease by capsule endoscopy ranged between 79.2 and 94.4%; kappa values ranged between 0.56 and 0.87. CONCLUSIONS Videocapsule endoscopy shows good sensitivity and excellent specificity for the detection of villous atrophy in patients with suspected celiac disease.

Abstract
BACKGROUND Video capsule endoscopy (VCE) may be useful for surveillance of small-bowel polyps in patients with familial adenomatous polyposis (FAP). OBJECTIVE To compare VCE to standard endoscopy for diagnosing small-bowel polyps in a defined segment of small bowel (proximal to a tattoo) and the entire examined small bowel. DESIGN Prospective. SETTING Single tertiary referral center. PATIENTS Participants with FAP (n = 32). The majority were selected for their high number of proximal small-bowel polyps and prior endoscopic tattoo placement in the proximal small bowel. INTERVENTIONS VCE (interpreted by 2 readers), push enteroscopy (PE), and lower endoscopy (LE) to count and measure small-bowel polyps. RESULTS In the defined segment, VCE detected a median of 10.0 (interquartile range [IQR], 5.0-19.0) and 9.0 (IQR, 6.0-16.0) polyps for each reader compared with a median of 41.0 (IQR, 19.0-64.0) polyps on PE (P = .002). Agreement between the 2 methods was fair (kappa = 0.34, 0.36). Agreement between VCE and PE was poor to fair (kappa = 0.10, 0.22) for estimating the size of the largest polyp and poor (kappa = -0.20, -0.27) for detecting large polyps (> or =1 cm). In the entire examined small bowel, VCE diagnosed a median of 38.0 (IQR, 10.5-71.5) and 54.0 (IQR, 13.0-100.0) polyps for each reader compared with a median of 123.0 (IQR, 38.5-183.0) for combination endoscopy (PE and LE) (P < .001). Agreement between the 2 methods was fair to moderate (kappa = 0.21, 0.56). LIMITATIONS Participants selected for high polyp burden, and results may not be applicable to all patients with FAP. CONCLUSIONS VCE underestimates the number of small-bowel polyps in persons with FAP and does not reliably detect large polyps.

Abstract
Video capsule endoscopy (VCE) is the most recent major practical and conceptual development in the field of endoscopy. The video capsule endoscope-a small, pill-sized, passive imaging device-has been demonstrated to be the pre-eminent imaging device for disorders of the small intestine. The initial use for VCE was to detect the origin of obscure gastrointestinal bleeding. Several other indications have now been justified, or are in the process of evaluation. More than 200,000 of these disposable devices have been used worldwide, with an extraordinarily good safety record: indeed, the device has been approved for use in children as young as 10 years of age. In addition, a double-ended capsule has now been approved for the evaluation of mucosal disease in the esophagus. The now-widespread deployment of the device into gastrointestinal practice in the US and many other countries suggests that VCE has achieved mainstream utility. The development of similar competitor devices, and devices whose movement can be controlled, is in progress.

Abstract
BACKGROUND AND AIMS Small bowel MR enteroclysis and wireless capsule endoscopy (WCE) are new diagnostic tools for the investigation of the small bowel. The aim of this study was to compare the diagnostic yield of WCE with MR enteroclysis in the detection of small bowel pathologies. METHODS A total of 36 patients were included in the study. Indications for imaging of the small bowel were proven or suspected small bowel Crohn's disease (CD; n=18), obscure gastrointestinal (GI) bleeding (n=14) and tumour surveillance (n=4). RESULTS In patients with Crohn's disease WCE detected significantly more inflammatory lesions in the first two segments of the small bowel compared with MR enteroclysis (12 patients vs. 1 patient, p=0.016). In 5 out of 14 (36%) patients with GI bleeding, angiodysplasia was detected as a possible bleeding source. Three of these patients had active bleeding sites detected by WCE. One patient had scattered inflammation of the mucosa. MR enteroclysis did not reveal any intestinal abnormalities in this patient group. MR enteroclysis provided extraintestinal pathologies in 10 out of 36 (28%) patients. CONCLUSION In patients with Crohn's disease WCE revealed significantly more inflammatory lesions in the proximal and middle part of the small bowel in comparison to MR enteroclysis, whereas in patients with obscure GI bleeding WCE was superior to MR enteroclysis.

Abstract
PURPOSE Ileal pouch-anal anastomosis is one of the two main options available for the surgical treatment of patients with familial adenomatous polyposis. Its main advantage is the minimal risk of rectal cancer but a possible Achilles heel is the recurrence of epithelial neoplasia at the ileal pouch-anal anastomosis and within the ileal pouch. The significance of ileoanal anastomotic and ileal pouch adenomas is not yet fully appreciated, and there is a false sense of security about this operation. The consequences of worsening pouch polyposis are serious in that endoscopic treatment is unlikely to be an effective way of controlling it. This study has been done to alert those caring for patients with familial adenomatous polyposis to the looming danger of pouch polyposis and to suggest ways to deal with it. METHODS Studies reporting ileoanal pouch adenomas, ileal pouch-anal anastomotic cancers, and ileal pouch cancers in patients with familial adenomatous polyposis were reviewed. Reports of adenomas in Kock pouches and in Brooke ileostomies in the setting of familial adenomatous polyposis were included. The primary end points of the study were the time between pouch construction and the diagnosis of neoplasia, the age of the patients at the diagnosis of neoplasia, and the severity of the neoplasia. RESULTS There were 18 studies reporting pouch neoplasia, 15 with adenomas, and 3 with cancer. Ten were case reports, five were retrospective studies, and three were prospective studies. All three prospective studies showed that the incidence of pouch adenomas increases with time of follow-up and that the severity of the polyposis varies. The median time from pouch construction to diagnosis of pouch adenomas was 4.7 years and the range was 0.5 to 12 years. There were six studies reporting eight patients with cancer at the ileal pouch-anal anastomosis, diagnosed a median of 8 years after pouch construction (range, 3-20 years). One-half of the cancers were locally advanced (T4) and one-half were not (T1 or T2). One-half followed stapled anastomosis and one-half were after mucosectomy. There were eight case reports of cancer described in an ileostomy in patients with familial adenomatous polyposis. The median time from ileostomy construction to the ileostomy cancers was 25 (range, 9-40) years. DISCUSSION The combination of fecal stasis, adenomatous epithelium, and a germline APC mutation is a potent recipe for epithelial neoplasia. There is increasing evidence that this happens in an ileostomy but that the process is much faster in an ileal pouch. Endoscopic treatment of ileal adenomas is likely to be difficult, reducing the options for their control to excising the entire pouch or chemoprevention.

Abstract
BACKGROUND Capsule endoscopy has demonstrated its clinical utility in the evaluation of the small bowel, and, accordingly, it has been suggested that it could be useful for the identification of small-intestinal polyps in patients with polyposis syndromes. The objective was to establish the effectiveness of wireless capsule endoscopy for detecting small-bowel polyps in patients with hereditary GI polyposis syndromes in comparison with barium contrast series. METHODS Consecutive patients with GI polyposis syndromes were included. Small-bowel follow-through series and capsule endoscopy were performed within 1 week, in a blind fashion. The number and the location of polyps were analyzed. RESULTS Twenty-four patients with familial adenomatous polyposis (n = 20) or Peutz-Jeghers syndrome (n = 4) were included. Capsule endoscopy detected small-bowel polyps in 7 of 24 patients (29%), whereas a barium contrast study identified small-intestinal polyps in only 3 of these 7 patients. In the 4 remaining patients, all of them with familial adenomatous polyposis, polyps detected by the capsule but missed in radiographic series were located at either ileum (2 patients), jejunum (1), or duodenum (1). No procedure-related complication was observed in any patient. CONCLUSIONS Wireless capsule endoscopy is a highly accurate technique for the detection of small-bowel polyps in patients with hereditary GI polyposis syndromes, and it represents a valuable alternative to barium contrast series in the surveillance of patients with Peutz-Jeghers syndrome.

Abstract
Few advances in the history of gastroenterology have made as dramatic an impact on the diagnosis of gastrointestinal disease as the development and rapid clinical implementation of wireless capsule endoscopy. Less than 4 years after the landmark publication, capsule endoscopy is widely considered an essential component of the diagnostic workup of obscure gastrointestinal bleeding, and its role is expanding in the diagnosis of small bowel diseases such as Crohn's disease. This review appraises the available literature and highlights practical aspects of capsule endoscopy of interest to the clinician. We discuss safety concerns, optimal preparation for the procedure, diagnostic utility as compared to conventional methods, indications for capsule endoscopy, and outcomes.

Abstract
Capsule endoscopy represents a significant advance in the investigation of small bowel diseases and the beginning of wireless endoscopic imaging. Capsule endoscopy involves swallowing a video capsule endoscope, which is painless and relatively safe. Its use has been established for suspected small bowel bleeding, and the role of capsule endoscopy in the investigation of inflammatory bowel disease, iatrogenic disease, polyposis syndromes and coeliac disease is evolving. It is likely that in many instances it will become the next test after standard endoscopic evaluation. Early data suggest that capsule endoscopy improves outcome in patients with suspected small bowel bleeding, but more data are required on outcomes for the other indications.
