(Niv Y et al, 2004;Cave D et al, 2004;Ning D et al, 2005) However, a number of recent studies and meta-analyses concluded that bowel preparation is not necessary, as it does not improve the image quality or diagnostic rate of CE investigations. This conclusion is also supported by the latest consensus reports (de Franchis R et al, 2005) as well as by official recommendations given by several major capsuleproducing companies.…”

“…Efforts are being made to control the transit of the capsule and to optimize cleansing of the small bowel (20,21). The consensus at this point is that the use of bowel preparations and pro-kinetics may reduce the number of failed examinations, but the optimal solution has yet to be found (22).…”

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...

“…At present, although all published papers strongly underlined that small bowel cleanliness is a key point to ensure a complete and accurate examination, and several papers aimed at evaluating factors (dietary restrictions and/or laxatives and/or prokinetic and/or postural tricks) potentially affecting small bowel cleanliness [12,14,16,17,[89][90][91][92][93] have been published, there are still no recommendations about small bowel preparation for capsule endoscopy.…”

Capsule endoscopy has revoluzionized the study of the small bowel by providing a reliable method to evaluate, endoscopically, the entire small bowel. In the last six years several papers have been published exploring the possible role of this examination in different clinical conditions. At the present time capsule endoscopy is generally recommended as a third examination, after negative bidirectional endoscopy, in patients with obscure gastrointestinal bleeding. A growing body of evidence suggests also an important role for this examination in other clinical conditions such as Crohn's disease, celiac disease, small bowel polyposis syndromes or small bowel tumors. The main complication of this examination is the retention of the device at the site of a previously unknown small bowel stricture. However there are also some other open issues mainly due to technical limitations of this tool (which is not driven from remote control, is unable to take biopsies, to insufflate air, to suck fluids or debris and sometimes to correctly size and locate lesions).The recently developed double balloon enteroscope, owing to its capability to explore a large part of the small bowel and to take targeted biopsies, although being invasive and time consuming, can overcome some limitations of capsule endoscopy. At the present time, in the majority of clinical conditions (i.e. obscure GI bleeding), the winning strategy seems to be to couple these two techniques to explore the small bowel in a painless, safe and complete way (with capsule endoscopy) and to define and treat the lesions identified (with double balloon enteroscopy).

Capsule endoscopy: role of bowel preparation in successful visualization

Abstract: Bowel preparation with sodium phosphate before capsule endoscopy offers better visualization than overnight fasting alone and induces fewer disturbances by intraluminal turbid fluid.
