Second-generation colon capsule endoscopy for detection of colorectal polyps: Systematic review and meta-analysis of clinical trials Open
Background and study aims Adherence to colorectal cancer (CRC) screening is still unsatisfactory in many countries, thereby limiting prevention of CRC. Colon capsule endoscopy (CCE), a minimally invasive procedure, could be an alternative …

A Single-Center Case Series of Endoscopically Treated Aorto-Gastrointestinal Fistula after Endovascular Aortic Repair: Surgery Is Still the Only Valid Solution Open
Introduction: Aortoesophageal fistula (AEF) is a life-threatening complication associated with endovascular aortic repair (EVAR) and occurs mostly in patients who undergo thoracic EVAR (TEVAR). To date, surgical treatment of AEF has been c…

Colon Capsule Endoscopy: Indications, Findings, and Complications – Data from a Prospective German Colon Capsule Registry Trial (DEKOR) Open
CCE seems to be a reliable and safe endoscopic tool for screening for CRC and detecting other diseases. Its patient acceptance and feasibility seems to be high, especially in the outpatient setting.

P417 10 years of endoscopic therapy of symptomatic Crohn’s disease stenoses: a retrospective analysis of long-term results Open
Endoscopic dilation of stenoses in patients with Crohn’s disease provides a less invasive way to avoid or reduce the number of bowel resections and, thereby, improve the quality of life. To the best our knowledge, only few studies with sma…
