7 recent reports on interventional endoscopy

Healio Gastroenterology and Liver Disease presents the following reports on the most recent research in endoscopy.

These reports review some of the most recent developments on computer-assisted colonoscopy, new duodenoscopes and polypectomy during insertion.

Real-time colonoscopy system increases adenoma yield

A real-time colonoscopy quality improvement system known as ENDOANGEL helped improve adenoma detection, according to study results.

Honggang Yu, MD, PhD, of the department of gastroenterology at Wuhan University, and colleagues wrote that blind spots come up during colonoscopies because of endoscope slipping and differences in control among endoscopists. READ MORE

FDA clears endoscopy platform for use at ambulatory surgery centers

The FDA has given 510(k) clearance to the IMAGINA Endoscopy System, an endoscopy platform for gastrointestinal procedures at ambulatory surgery centers, according to a press release from the manufacturer, PENTAX Medical.

“It’s a completely new concept in endoscopy, featuring new technology that delivers superior visualization with an attractive cost model,” Stepan Suchanek, MD, PhD, of the Centre for Gastrointestinal Endoscopy in Czech Republic, said in the release. “Overall, it helps us provide efficient and effective treatment while reducing financial burdens to the health system.” READ MORE

Computer-aided colonoscopy improves adenoma detection

A computer-aided colonoscopy system helped detect adenomas that were initially missed by the endoscopist, according to study results.

Pu Wang, MD, of the department of gastroenterology at Sichuan Academy of Medical Sciences and Sichuan People’s Hospital in China, and colleagues wrote that even with recent advances in colorectal cancer screening technology, some adenomas are still missed. READ MORE

FDA encourages innovative duodenoscope designs, reprocessing procedures

In its ongoing effort to limit potential disease transmission due to difficult-to-clean devices, the FDA is recommending a transition to duodenoscopes with innovative designs and is encouraging the development of new methods to clean the scopes, according to recent safety communication.

In August, the FDA recommended a transition to duodenoscopes with disposable components. In this updated communication, the agency is recommending that hospitals and other endoscopy centers transition away from fixed endcap duodenoscopes to ones with newer features that “facilitate or eliminate the need for reprocessing.” READ MORE

Culture, quarantine effectively identify contaminated duodenoscopes

First and even second time high-level disinfection may not be enough to eliminate bacterial contamination in duodenoscopes, but a culture and quarantine program can help identify which scopes need more attention, according to study results.

“Because of the concerns of duodenoscope-transmitted infections, in 2015 our institution re-evaluated duodenoscope cleaning and reprocessing practices and instituted [high-level disinfection] followed by a culture and quarantine protocol to decrease risks of infection,” Jacob Mark, MD, of the division of pediatric gastroenterology, hepatology and nutrition at Children’s Hospital Colorado, and colleagues wrote. “This study aimed to evaluate the results of this protocol and with culture results and active monitoring for duodenoscope-transmitted infections.” READ MORE

Endocuff Vision misses fewer adenomas than cuff-assisted endoscopy

The Endocuff Vision endoscopy device achieved a higher adenoma detection rate and missed fewer adenomas than cap-assisted endoscopy, according to study results.

Rajaratnam Rameshshanker, MBBS, MRCP, from St. Mark’s Hospital and Academic Institute in the United Kingdom, and colleagues wrote that devices like Endocuff Vision (Arc Medical Design) and cap-assisted endoscopy (CAC) are designed to counteract some of the factors that make adenoma detection difficult, and they sought to compare the devices head-to-head.

Polypectomy during colonoscopy insertion reduces procedure time, missed polyps

Removing polyps that are unintentionally located during the colonoscopy insertion phase rather than waiting until withdrawal helped reduce the number of missed polyps and shortened the total procedure time, according to study results.

Akira Teramoto, MD, of the Sano Hospital gastrointestinal center in Japan, and colleagues wrote that there are currently no clear recommendations for the management of polyps that are found during insertion. READ MORE
