New endoscopes and add-on devices to improve colonoscopy performance

引用

World Journal of Gastroenterology 2017年第21期23卷 3784-3796页

作者： paraskevas gkolfakis georgios tziatzios george d dimitriadis konstantinos triantafyllou hepatogastro--enterology unit second department of internal medicine propaedeutic research institute and diabetes center medical school national and kapodistrian university of athens attikon university general hospital

Colonoscopy is the gold standard for colorectal cancer prevention; however, it is still an imperfect modality. Precancerous lesions can be lost during screening examinations, thus increasing the risk of interval cancer. A variety of factors either patient-, or endoscopist dependent or even the procedure itself may contribute to loss of lesions. Sophisticated modalities including advanced technology endoscopes and add-on devices have been developed in an effort to eliminate colonoscopy's drawbacks and maximize its ability to detect potentially culprit polyps. Novel colonoscopes aim to widen the field of view. They incorporate more than one cameras enabling simultaneous image transmission. In that way the field of view can expand up to 330°. On the other hand a plethora of add-on devices attachable on the standard colonoscope promise to detect lesions in the proximal aspect of colonic folds either by offering a retrograde view of the lumen or by straightening the haustral folds during withdrawal. In this minireview we discuss how these recent advances affect colonoscopy performance by improving its quality indicators(cecal intubation rate, adenoma detection rate) and other metrics(polyp detection rate, adenomas per colonoscopy, polyp/adenoma miss rate) associated with examination's outcomes.

An unusual case of prolonged post-endoscopic retrograde cholangiopancreatography jaundice

引用

Hepatobiliary & Pancreatic Diseases International 2016年第2期15卷 220-222页

作者： georgios Tziatzios Paraskevas Gkolfakis Ioannis S Papanikolaou George dimitriadis Konstantinos Triantafyllou Hepatogastroenterology Unit 2nd Department of Internal Medicine and Research Institute "Attikon" University General Hospital Medical School University of Athens

Despite the effectiveness of endoscopic retrograde cholangiopancreatography（ERCP） for the treatment of choledocholithiasis, various complications have been described. We herein report the first case of prolonged postERCP jaundice due to toxicity of the contrast agent Iobitridol（~174;XENETIX, Guerbet, Roissy Cd G Cedex, France） in a patient who underwent ERCP with sphincterectomy and common bile duct stone removal. While clinical improvement and normalization of aminotransferases and cholestatic enzymes after the procedure, an unexplained increase of direct bilirubin was noticed. A second ERCP was performed one week later, excluding possible remaining choledocholithiasis. Nevertheless, serum direct bilirubin increased further up to 15 mg/d L. Other potential causes of direct hyperbilirubinemia were ruled out and patient＇s liver biopsy was compatible with drug-induced liver toxicity. Additionally, the cause-result time connection between the use of Iobitridol and bilirubin increase indicated the possibility of a toxic effect related to the repeated use of the particular contrast agent. Iobitridol, a contrast agent, can induce prolonged direct hyperbilirubinemia.
