Endoscopic fenestration for benign complete anastomotic obstruction following rectal surgery

Post written by Jun Takada, MD, PhD, from the Department of Gastroenterology, Gifu University Graduate School of Medicine, Gifu, Japan. This video case is about a 62-year-old man who developed an obstruction in the anastomotic region 6 months after Hartmann’s surgery for rectal cancer. Colonoscopies performed through the anal and ileal stoma showed complete anastomotic …

New concept for colonoscopy including side optics and artificial intelligence

Post written by Joel Troya, MSc, from Interventional and Experimental Endoscopy (InExEn), Internal Medicine II, University Hospital Würzburg, Würzburg, Germany. The combination of artificial intelligence (AI) and side optics might help detect adenomas that otherwise could be missed. Several studies have demonstrated that the adenoma detection rate is the critical parameter for reducing the incidence …

Linked color imaging, mucosal exposure device, their combination, and standard colonoscopy for adenoma detection

Post written by Satimai Aniwan, MD, from the Gastrointestinal Endoscopy Excellence Center, Division of Gastroenterology, Chulalongkorn University and King Chulalongkorn Memorial Hospital, Thai Red Cross Society, Bangkok, Thailand.    Colonoscopy primarily aims to detect and remove colorectal adenomas, which is a precancerous lesion. Most postcolonoscopy colorectal cancer is attributed to the missed lesion at the previous …

Acute physiologic effects of N95 respirator use on gastroenterologists performing simulated colonoscopy

Post written by Asif Khalid, MD, from the VA Pittsburgh HealthCare System, and the University of Pittsburgh Medical System, Pittsburgh, Pennsylvania, USA. Gastroenterologists and GI lab staff are required to use N95 respirators while performing aerosol generating endoscopic procedures during the SARS-CoV-2 pandemic. Unfortunately, N95 respirator use is associated with the development of multiple symptoms. …

Water-assisted colonoscopy: an international modified Delphi review on definitions and practice recommendations

Post written by Sauid Ishaq, FRCP, PhD, from Russell Hall, Dept. of Gastroenterology, and Birmingham City University, Birmingham, United Kingdom. The focus of the study was to get consensus among experienced colonoscopists (experts and non-experts in WAC) on definitions and practice of water immersion (WI), water exchange (WE), and UWR. Water-assisted colonoscopy (WAC) and underwater …

Editor’s Choice: Second-generation distal attachment cuff improves adenoma detection rate

GIE Associate Editor, Dr. Seth Gross, highlights this article from the March issue “Second-generation distal attachment cuff improves adenoma detection rate: meta-analysis of randomized controlled trials” by Harsh K. Patel, MBBS, et al. This study shows the benefits of mechanical enhancement during colonoscopy, which can improve a key quality metric, adenoma detection rate. Colonoscopy is a …

The National Polyp Study at 40: challenges then and now

Post written by Sidney J. Winawer, MD, and Ann G. Zauber, PhD, from the Gastroenterology, Hepatology and Nutrition Service, Department of Medicine, and the Department of Epidemiology and Biostatistics, Memorial Sloan Kettering Cancer Center, New York, New York, USA. Colonoscopy was introduced in the 1970s, making it possible for the first time to directly examine …

New insights on missed colonic lesions during colonoscopy through artificial intelligence–assisted real-time detection

Post written by Wai K. Leung, MD, from the Department of Medicine, Queen Mary Hospital, University of Hong Kong, Hong Kong. This study aimed to determine whether the use of artificial intelligence (AI)-assisted real-time detection could reduce colorectal adenoma miss rate during colonoscopy. Previous studies showed that up to 26% of adenomas could be missed …

Use of a rigidizing overtube to complete an incomplete colonoscopy

Post written by Mike T. Wei, MD, from Stanford University, Stanford, and Veterans Affairs Palo Alto, Palo Alto California. We present a case of a 64-year-old man with history of C5 spinal cord injury who presented for screening colonoscopy. Unfortunately, due to significant looping, the colonoscope was only able to reach the transverse colon. The colonoscope …
