Olympus reviewed the literature titled "incidence and management of cystic duct perforation during endoscopic transpapillary gallbladder drainage for acute cholecystitis"by kazunari nakahara, et al.This retrospective single-center study was aimed to investigate the incidence of cystic duct perforation (cdp) as a specific adverse event during the endoscopic transpapillary gallbladder drainage (etgbd) procedure, also the management and the clinical outcome of cdp during etgbd.Out of 249 consecutive patients with acute cholecystitis (ac) included who underwent etgbd, cdp was observed in 23 (9.2%) patients and was caused by the gw and cannula, with no perforations by stents or catheters.The study reported technical success rate was 53.5% (8/15) for cdp caused by gws and 25.0% (2/8) for cdp caused by cannulas with a reported rate of technical success was 53.5% (8/15) for cdp caused by gws and 25.0% (2/8) for cdp caused by cannulas.The study also claimed that etgbd technical success rates, procedure times, and hospitalization periods were significantly inferior in the cdp group (n = 23) compared with the non-cdp group (n = 216).In conclusion, the cdp reduced the etgbd technical success rate.However, even in patients with cdp, an improvement of ac was achieved by subsequent successful etgbd or additional procedures.Adverse events: cdp group: acute pancreatitis (mild and moderate severity in one each); both improved with conservative treatment.(n=2).Cdp during etgbd, caused by guidewire (n=15): an improvement of acute cholecystitis was achieved by subsequent successful etgbd or additional procedures, such as percutaneous drainage.Cdp was defined as the dislocation of devices, such as gw or cannula, or the leakage of contrast media into the peritoneal cavity from the cystic duct lumen confirmed by fluoroscopic imaging.Non-cpd group: pancreatitis - (11).Bleeding - (1).This article includes 2 reports for the olympus devices and reported adverse events: (b)(6): jf-260v or tjf-260v, evis lucera duodenovideoscope.Jf-260v was selected as a representative device.(b)(6): tjf-q290v, evis lucera elite duodenovideoscope this is report 1 of 2 for (b)(6): jf-260v or tjf-260v, evis lucera duodenovideoscope.Jf-260v was selected as a representative device.
