The development of new capsules now allows endoscopic diagnosis in all segments of the gastrointestinal tract and comes with new needs for differentiated preparation regimens. Although the literature is steadily increasing, the results of the conducted trials on preparation are sometimes conflicting. The ingestion of simethicone before gastric and small bowel capsule endoscopy for prevention of air bubbles is established. The value of a lavage before small bowel capsule endoscopy (SBCE) is recommended, although not supported by all studies. Ingestion in the morning before the procedure seems useful for the improvement of mucosa visualization. Lavage after swallowing of the capsule seems to improve image quality, and in some studies also diagnostic yield. Prokinetics has been used with first generation capsules to shorten gastric transit time and increase the rate of complete small bowel visualization. With the massively prolonged battery capacity of the new generation small bowel capsules, prokinetics are only necessary in significantly delayed gastric emptying as documented by a real-time viewer. Lavage is crucial for an effective colon capsule or pan-intestinal capsule endoscopy. Mainly high or low volume polyethylene glycol (PEG) is used. Apart from achieving optimal cleanliness, propulsion of the capsule by ingested boosts is required to obtain a complete passage through the colon within the battery lifetime. Boosts with low volume sodium picosulfate (NaP) or diatrizoate (gastrografin) seem most effective, but potentially have more side effects than PEG. Future research is needed for more patient friendly but effective preparations, especially for colon capsule and pan-intestinal capsule endoscopy.

Capsule endoscopy (CE) has proven to be a valuable diagnostic modality for small bowel diseases over the past 20 years, particularly Crohn’s disease (CD), which can affect the entire gastrointestinal tract from the mouth to the anus. CE is not only used for the diagnosis of patients with suspected small bowel CD, but can also be used to assess disease activity, treat-to-target, and postoperative recurrence in patients with established small bowel CD. As CE can detect even mildly non-specific small bowel lesions, a high diagnostic yield is not necessarily indicative of high diagnostic accuracy. Moreover, the cost effectiveness of CE as a third diagnostic test employed usually after ileocolonoscopy and MR or CT enterography is an important consideration. Recently, new developments in colon capsule endoscopy (CCE) have increased the utility of CE in patients with ulcerative colitis (UC) and pan-enteric CD. Although deflation of the colon during the examination and the inability to evaluate dysplasia-associated lesion or mass results in an inherent risk of overestimation or underestimation, the convenience of CCE examination and the risk of flare-up after colonoscopy suggest that CCE could be used more actively in patients with UC.

Abstract Background Crohn’s disease (CD) can involve the upper gastrointestinal (GI) tract as well as the small and large bowel. PillCam colon capsule endoscopy (PCCE-2) enables observation of the whole GI tract, but its diagnostic yield for CD lesions in the whole GI tract remains unknown. Aim To elucidate the diagnostic yield of PCCE-2 in patients with CD. Methods Patients with CD who underwent PCCE-2 and double-balloon endoscopy (DBE) using oral and anal approaches were evaluated for CD lesions in the whole GI tract. We divided the small bowel into three segments (jejunum, ileum, and terminal ileum), and the large bowel into four segments (right colon, transverse colon, left colon, rectum). Detection of ulcer scars, erosion, ulcers, bamboo joint-like appearance, and notch-like appearance was assessed in each segment. The diagnostic yield of PCCE-2 was analyzed based on the DBE results as the gold standard. Results Of the total 124 segments, the sensitivities of PCCE-2 for ulcer scars, erosion, and ulcers were 83.3%, 93.8%, and 88.5%, respectively, and the specificities were 76.0%, 78.3%, and 81.6%, respectively. For the 60 small bowel segments, the sensitivities were 84.2%, 95.5%, and 90.0%, respectively, and the specificities were 63.4%, 86.8%, and 87.5%, respectively. For the 64 large bowel segments, the sensitivities were 80.0%, 90.0%, and 83.3%, respectively, and the specificities were 84.7%, 72.2%, and 77.6%, respectively. Conclusion PCCE-2 provides a high diagnostic yield for lesions in the whole GI tract of patients with CD. Thus, we recommend its use as a pan-enteric tool in clinical settings.

Observing the entire small bowel is difficult due to the presence of complex loops and a long length. Capsule endoscopy (CE) provides a noninvasive and patient-friendly method for visualizing the small bowel and colon. Small bowel capsule endoscopy (SBCE) has a critical role in the diagnosis of small bowel disorders through the direct observation of the entire small bowel mucosa and is becoming the primary diagnostic tool for small bowel diseases. Recently, colon capsule endoscopy (CCE) was also considered safe and feasible for obtaining sufficient colonic images in patients with incomplete colonoscopy, in the absence of bowel obstruction. This review article assesses the current status of CE in terms of the diagnostic yield and the clinical impact of SBCE in patients with obscure gastrointestinal bleeding, who have known or suspected Crohn’s disease, small bowel tumor and inherited polyposis syndrome, celiac disease, and those who have undergone CCE.

Introduction. The small bowel capsule endoscopy is the first line procedure in patients with suspected small bowel bleeding. Data regarding overt suspected small bowel bleeding and its predictive factors remain still limited. Aim. To assess the diagnostic yield of the capsule endoscopy and the factors predicting positive findings in patients with overt suspected small bowel bleeding. Methods. Patients with overt suspected small bowel bleeding (melena or enterorrhagia) and negative upper and lower endoscopy were included. A positive diagnostic yield was considered when the capsule endoscopy diagnosed one or more P2 or P3 type lesions (Modified Saurin Classification) Demographic and laboratory data were recorded. Results. 79 patients were included (mean age 62.92 (15-89); F:M 46:33). The diagnostic yield of the capsule endoscopy was 62%. The most frequent finding was angioectasia (44.8%), followed by nonspecific inflammation/ulceration (20.4%). The multivariate analysis found that age older than 50 years and male sex were independent variables that were associated with an increased risk of positive findings and angioectasia. Conclusions. In this group of patients with overt suspected small bowel bleeding, the capsule endoscopy was useful (with a diagnostic yield of 62%). The most frequent lesions were the vascular ones. Age over 50 and male sex were independent predictors of finding lesions and angioectasia.

Abstract Background Small-bowel capsule endoscopy is advocated and repeat upper gastrointestinal (GI) endoscopy should be considered for evaluation of recurrent or refractory iron deficiency anemia (IDA). A new device that allows magnetic steering of the capsule around the stomach (magnetically assisted capsule endoscopy [MACE]), followed by passive small-bowel examination might satisfy both requirements in a single procedure. Methods In this prospective cohort study, MACE and esophagogastroduodenoscopy (EGD) were performed in patients with recurrent or refractory IDA. Comparisons of total (upper GI and small bowel) and upper GI diagnostic yields, gastric mucosal visibility, and patient comfort scores were the primary end points. Results 49 patients were recruited (median age 64 years; 39 % male). Combined upper and small-bowel examination using the new capsule yielded more pathology than EGD alone (113 vs. 52; P < 0.001). In upper GI examination (proximal to the second part of the duodenum, D2), MACE identified more total lesions than EGD (88 vs. 52; P < 0.001). There was also a difference if only IDA-associated lesions (esophagitis, altered/fresh blood, angioectasia, ulcers, and villous atrophy) were included (20 vs. 10; P = 0.04). Pathology distal to D2 was identified in 17 patients (34.7 %). Median scores (0 – 10 for none – extreme) for pain (0 vs. 2), discomfort (0 vs. 3), and distress (0 vs. 4) were lower for MACE than for EGD (P < 0.001). Conclusion Combined examination of the upper GI tract and small bowel using the MACE capsule detected more pathology than EGD alone in patients with recurrent or refractory IDA. MACE also had a higher diagnostic yield than EGD in the upper GI tract and was better tolerated by patients.
