Improving suboptimal bowel prep using a novel on-demand overtube device: an in vivo animal study
Inadequate bowel preparation for a colonoscopy can occur in more than 25% of cases.1 This is associated with increased patient cost because of the need for additional examinations, reduced diagnostic yield, and increased risk of interval colorectal cancer.2,3 A recently developed, novel overtube (OT) device (IzoScope; IzoMed Inc, Irvine, Calif, USA) can safely and efficiently seal a compartment of the colon to administer targeted fluid lavage (eg, right colonic enema). We performed a proof-of-concept study using a single domestic pig to describe the use of this device to address segmental suboptimal bowel preparation and improve visibility during colonoscopy (Video 1, available online at www.giejournal.org ).Quit screwing around: magnetic retrieval of an appendiceal foreign body
Appendiceal foreign bodies are uncommon but can lead to serious adverse events such as appendicitis and perforation. Patients can remain asymptomatic for many years before these adverse events develop. Data on incidence and optimal management are limited and largely restricted to case reports in both adults and children.1-6 In a review spanning 100 years with 250 identified case reports, objects that were sharp, thin, stiff, and pointed increased the risk of adverse events.7 Timely intervention is recommended before the development of localized inflammation or perforation.
