The Cold Revolution: How Far Can It Go?

Cold resection for small colonic polyps, and larger lesions, is being rapidly and widely adopted. Driven by an impressive safety and cost profile compared with conventional polypectomy, these advantages are offset by the limitations of smaller and shallower resection, and absent thermal effects that may permit persistence of residual neoplasia. To overcome this, optimal cold snare technique requires inclusion of a margin of normal mucosa and a piecemeal resection technique for larger polyps.

Cold EMR of large sessile serrated polyps at colonoscopy (with video).

Background And Aims: The optimal technique for the resection of sessile serrated polyps (SSPs) is unknown, with established limitations and risks with conventional polypectomy. Although cold snare polypectomy is safe, the efficacy of piecemeal resection for large lesions is untested. In this study we evaluate the safety and efficacy of cold EMR for large SSPs.

Patient acceptance of the optical diagnosis and misdiagnosis of diminutive colorectal polyps.

Background And Aims: Optical diagnosis allows for real-time endoscopic assessment of colorectal polyp histology and consists of the resect and discard and diagnose and leave paradigms. This survey assessed patient acceptance of optical diagnosis and their responses to a hypothetical doomsday scenario.

Methods: We conducted a 3-month cross-sectional survey of colonoscopy outpatients presenting to an Australian academic endoscopy center.

Feasibility and Safety of Overtubes for PEG-Tube Placement in Patients with Head and Neck Cancer.

Background. Percutaneous endoscopic gastrostomy (PEG) placement using the "pull" technique is commonly utilized for providing nutritional support in head and neck cancer (HNC) patients, but it may be complicated by peristomal metastasis in up to 3% of patients. Overtube-assisted PEG placement might reduce this risk.
