| 1 | Contraindications for video capsule endoscopy显示文摘Video capsule endoscopy(VCE) has been applied in the last 15 years in an increasing field of applications. Although many contraindications have been put into perspective, some precautions still have to be considered. Known stenosis of the gastrointestinal tract is a clear contraindication for VCE unless surgery is already scheduled or at least has been considered as an optional treatment modality. In patients with a higher incidence of stenosis, as in an established diagnosis of Crohn's disease, clinical signs of obstruction, prior radiation or surgical small bowel resection, a preceding test with the self-dissolving patency capsule can override this contraindication. Endoscopic placement of the capsule should be considered in patients with swallowing disorders to avoid aspiration. Esophageal or gastric motility disorders may require endoscopic capsule transport or application of prokinetics if the real-time viewer proofs delayed transit. In pregnant women, VCE should be restricted to urgent cases where diagnosis cannot be postponed after delivery, as data on safety are missing. There is theoretical and clinical evidence that patients with implanted cardiac devices such as a pacemaker, cardioverters or left heart assist devices, can safely undergo VCE in spite of still existing contraindication by manufacturers. Children from the age of 2 years have safely undergone VCE. Although video capsules are not proven safe with magnetic resonance imaging(MRI), first single cases of patients incidentally undergoing MRI with an incorporated capsule have been reported, showing susceptibility artifacts but no signs of clinical harm. | Dirk Bandorski Niehls Kurniawan Peter Baltes Reinhard Hoeltgen Matthias Hecker Dominik Stunder Martin Keuchel | 2016 | World Journal of Gastroenterology2016，22，45： | 2 |

| 5 | PillCamColon2 after incomplete colonoscopy-A prospective multicenter study显示文摘AIM To evaluate the ability of PillCamColon2 to visualize colonic segments missed by incomplete optical colonoscopy(OC) and to assess the diagnostic yield.METHODS This prospective multicentre study included 81 patients from nine centres who underwent second-generation colon capsule endoscopy(CCE) following incomplete OC performed by an experienced gastroenterologist(> 1000 colonoscopies). Patients with stenosis were excluded. According to patient preferences, CCE was performed the following day(protocol A) after staying on clear liquids and 0.75 L Moviprep in the morning or within 30 d after new split-dose Moviprep(protocol B). Boosts consisted of 0.75 L and 0.25 L Moviprep, and phospho-soda was given as a rescue if the capsule was not excreted after seven hours.RESULTS Seventy-four patients were analysed(51% of them in group A; 49% in group B). Bowel cleansing was adequate in 67% of cases, and CCE could visualize colonic segments missed by incomplete colonoscopy in 90% of patients under protocol A and 97% of patients under protocol B(P = 0.35, n.s.). Significant polyps including adenocarcinoma were detected in 24% of cases. Detection rates for all polyps and significant polyps per patient were similar in both protocols. Polyps were found predominantly in the right colon(86%) in segments that were not reached by OC. Extracolonic findings-such as reflux esophagitis, suspected Barrett esophagus, upper GI-bleeding, gastric polyps, gastric erosions and angiectasia-were detected in eight patients. Pill Cam Colon2 capsule was retained in the ileum of one patient(1.4%) without symptoms and removed during an uneventful resection for unknown Crohn's disease that was diagnosed as the cause of anemia, which was the indication for colonoscopy. CCE was well tolerated. One patient suffered from selflimiting vomiting after consuming the phospho-soda.CONCLUSION Second-generation CCE using a low-volume preparation is useful after incomplete OC, and it allows for the detection of additional relevant findings, but cleansing efficiency could be improved. | Peter Baltes Marc Bota Jorg Albert Michael Philipper Hans-Georg Horster Friedrich Hagenmüller Ingo Steinbrück Ralf Jakobs Matthias Bechtler Dirk Hartmann Horst Neuhaus Jean-Pierre Charton Rupert Mayershofer Horst Hohn Thomas Rosch Stefan Groth Tanja Nowak Peter Wohlmuth Martin Keuchel | 2018 | World Journal of Gastroenterology2018，24，31： | 1 |
