Evaluation of safety, efficacy, and ease of use for screening and surveillance colonoscopy by using a single-use colonoscope with wide-angle field of view

Post written by Nathan Gluck, MD, PhD, from the Research Center for Digestive Diseases, Gastroenterology Department, Tel-Aviv Sourasky Medical Center, and Tel-Aviv University Sackler Faculty of Medicine, Tel-Aviv, Israel.


We studied a novel single-use colonoscope with an extended 200º field of view, enabling view behind colonic folds and eliminating concerns related to reprocessing of devices.

Lesions missed by colonoscopy may lead to interval cancers, so extending the field of view may be beneficial. A single-use endoscope could alleviate concerns about infection transmission and potentially increase the uptake of colonoscopy for colorectal cancer screening.

In addition, low-volume endoscopy units could spare investments in reprocessing equipment, infrastructure, and personnel and improve their workflow.

Cecal intubation with the single-use device was achieved in all 79 participants with no serious adverse events or device effects. Physician proficiency was achieved rapidly after 3 to 6 procedures. Therapeutic interventions were successfully performed, and adenoma detection rate benchmarks were reached.

Larger screening trials will be required to confirm and quantify the benefit of the extended view.
