“…Previous studies investigating the yield of WCE in the detection of small intestinal lesions in comparison with various imaging techniques have shown that WCE is superior to CT enteroclysis and small-bowel follow-through [18][19][20][21]. Indeed, the introduction of WCE has significantly improved the diagnostic yield of small bowel tumors whose detection has been notoriously challenging due to the limitations of other imaging modalities.…”

Background & Aims: Neuroendocrine tumors (NETs) are a heterogeneous group of neoplasms with unclear etiology that may show functioning or non-functioning features. Primary tumor localization often requires integrated imaging. The European Neuroendocrine Tumors Society (ENETS) guidelines proposed wireless-capsule endoscopy (WCE) as a possible diagnostic tool for NETs, if intestinal origin is suspected. However, its impact on therapeutic management is debated. We aimed to evaluate the yield of WCE in detecting intestinal primary tumor in patients showing liver NET metastases when first-line investigations are inconclusive.Method: Twenty-four patients with histological diagnosis of metastatic NET from liver biopsy and no evidence of primary lesions at first-line investigations were prospectively studied in an ENETS-certified tertiary care center. Wireless-capsule endoscopy was requested before explorative laparotomy and intra-operative ultrasound. The diagnostic yield of WCE was compared to the surgical exploration.Results: Sixteen subjects underwent surgery; 11/16 had positive WCE identifying 16 bulging lesions. Mini-laparotomy found 13 NETs in 11/16 patients (9 small bowel, 3 pancreas, 1 bile ducts). Agreement between WCE and laparotomy was recorded in 9 patients (Sensitivity=75%; Specificity=37.5%; PPV=55%; NPV=60%). Correspondence assessed per-lesions produced similar results (Sensitivity=70%; Specificity=25%; PPV=44%; NPV=50%). No capsule retentions were recorded.Conclusions: Wireless-capsule endoscopy is not indicated as second-line investigation for patients with gastro-entero-pancreatic NETs. In the setting of a referral center, it might provide additional information when conventional investigations are inconclusive about the primary site.Abbreviations: DBE: double balloon enteroscopy; GEP-NET: gastro-entero-pancreatic neuroendocrine tumor; GI: gastrointestinal; ENETS: European Neuroendocrine Tumor Society; NET: neuroendocrine tumor; SSRS: somatostatin receptor scintigraphy; WCE: wireless capsule endoscopy.

Videocapsule endoscopy (VCE) has revolutionized our ability to visualize the small bowel mucosa. This modality is a valuable tool for the diagnosis of obscure small bowel Crohn's disease (CD), and can also be used for monitoring of disease activity in patients with established small-bowel CD, detection of complications such as obscure bleeding and neoplasms, evaluation of response to anti-inflammatory treatment and postoperative recurrence following small bowel resection. VCE could also be an important tool in the management of patients with unclassified inflammatory bowel disease, potentially resulting in reclassification of these patients as having CD. Reports on postoperative monitoring and evaluation of patients with ileal pouch-anal anastomosis who have developed pouchitis have recenty been published. Monitoring of colonic inflammatory activity in patients with ulcerative colitis using the recently developed colonic capsule has also been reported. Capsule endoscopy is associated with an excellent safety profile. Although retention risk is increased in patients with small bowel CD, this risk can be significanty decreased by a routine utilization of a dissolvable patency capsule preceding the ingestion of the diagnostic capsule. This paper contains an overview of the current and future WJG 20 th Anniversary Special Issues (3): Inflammatory bowel disease TOPIC HIGHLIGHTclinical applications of capsule endoscopy in inflammatory bowel disease.

“…Since then, more than 340 000 examinations (Given Imaging Ltd, Yoqneam, Israel, Spring 2006) have been performed worldwide with an overall complication rate of only 0.75% (6). Based on meta-analyses of published clinical results VCE has evolved to be the first line procedure in many hospitals (7)(8)(9)(10)(11)(12)(13), keeping small bowel radiology as method of choice for patients who cannot take the capsule (13). In order to understand the diagnostic algorithm of modern small bowel examination we will discuss the video capsule technique, its indications and contraindications, advantages and disadvantages, types of true and false lesions and comparative studies of VCE and radiological methods of investigation of the small intestine.…”

Capsule Enteroscopy and Radiology of the Small Intestine 2 ABSTRACT In a very few years, the video capsule for small bowel enteroscopy has gained widespread clinical acceptance. It is readily ingested, disposable, and allows for a complete, low-invasive endoscopic examination of the entire mucosa of the small bowel. It is a patient-friendly method and a first line procedure in the difficult evaluation of obscure gastrointestinal bleeding. It has the highest proven figure of diagnostic sensitivity for detecting lesions of the mucosa, irrespective of aetiology. The limitations of capsule endoscopy include difficulty in localizing mucosal lesions anatomically and its restricted use in patients with dysphagia, strictures or motor dysfunction. Strictures, transmural and extra-mural lesions in patients with small bowel Crohn's disease are evaluated by MRI-enterography and CT-enterography.Capsule Enteroscopy and Radiology of the Small Intestine 3 Imaging of the small bowel was, until recently, the responsibility of the radiologist, who, in dedicated centres, offered the patient not just a small-bowel follow-through with single exposures over time, but a dedicated, real time, fluoroscopic examination of a well distended small bowel, displayed in double-contrast and documented on spot films (1). This enteroclysis technique, well accepted by gastroenterologists, significantly improved both the detection of mucosal disease and the mapping of involved bowel segments. However, the duration of the examination, discomfort related to nasojejunal intubation and infusion of large volumes of contrast and distension materials, be it methyl cellulose or air (2), reduced general acceptance and dissemination of this method (3). VCE has evolved to be the first line procedure in many hospitals (7-13), keeping small bowel radiology as method of choice for patients who cannot take the capsule (13). In order to understand the diagnostic algorithm of modern small bowel examination we will discuss the video capsule technique, its indications and contraindications, advantages and disadvantages, types of true and false lesions and comparative studies of VCE and radiological methods of investigation of the small intestine. The video capsuleVCE was primarily developed for examination of small bowel mucosa (14,15). Rapid technical refinement has since resulted in a dedicated capsule for the oesophagus, and recently capsules for the study of both stomach and colon (16).The capsule measures 11 by 27mm and includes a light source and a camera inside a clear, transparent dome, batteries and a radio-transmitter (Figure 1). Whilst ushered forward by peristalsis the capsule transmits images continuously at two frames per second for around eight hours, a total of more than 60.000 images. The image has a 140° field of view, a focus depth of 1-30 mm, and an 8:1 magnification (17). An array of eight external detectors, applied to the abdominal wall, receives the images for storage in a solid state data recorder. Capsule Enteroscopy and Radiology of the Smal...
