Endoscopic ultrasound-guided colo-colostomy for the treatment of benign complete occlusion of colonic anastomosis: a case series and description of technique.

Aim: The incidence of benign colonic anastomotic stricture is approximately 2% in patients undergoing left hemicolectomy or anterior resection and as high as 16% in patients undergoing low anterior or intersphincteric resection. In the majority, rather than complete occlusion, a stenosis forms, which can be managed with endoscopic balloon dilatation, a self-expanding metallic stent or endoscopic electroincision. In the less common scenario of a completely occluded colonic anastomosis, surgery is often required.

Safety of the colonoscope magnetic imaging device (ScopeGuide) in patients with implantable cardiac devices.

Background And Study Aims: Use of the colonoscope magnetic imaging device (ScopeGuide, Olympus Medical Systems, Tokyo, Japan) is currently contraindicated by the manufacturer for patients with implantable cardiac devices, a group of patients that is increasing annually along with the number of colonoscopies performed in the era of colorectal cancer screening. This is the first study to examine the safety of ScopeGuide in patients with permanent pacemakers, implantable cardioverter defibrillators, and cardiac resynchronization therapy.

Patients And Methods: Nonimplanted cardiac devices were exposed to the electromagnetic field of ScopeGuide ex vivo and assessed for evidence of interference or change in device settings.

Comparison of Pentax HiLine and Olympus Lucera systems at screening colonoscopy.

Aim: To compare the performance characteristics of Pentax HiLine (PHL) (with i-scan) and Olympus Lucera (OL) systems in a screening population.

Methods: Screening colonoscopies in asymptomatic guaiac faecal occult blood test-positive patients with PHL (n = 58) and OL (n = 425) colonoscopes were analysed. All procedures were performed by a single colonoscopist.
