Abstract

BACKGROUND AND AIM:Intubation of the terminal ileum (TI) demonstrates a complete colonoscopy, but its clinical value during screening exams is unknown. We aimed to determine whether TI intubation during screening colonoscopy is associated with colonoscopy quality measures or identifies subclinical pathology. METHODS:We performed a retrospective cohort study examining average-risk screening colonoscopies performed at an academic health system between July 2016 and October 2017. Data were extracted from an internal colonoscopy quality registry and the electronic health record. Appropriate statistical tests were used for group comparisons, to correlate TI intubation rate (TIIR) with measures of colonoscopy quality and to examine factors associated with the likelihood of TI intubation. RESULTS:There were 7799 colonoscopies performed with adequate prep quality by 28 gastroenterologists. Most patients were female (56.4%) with a median age of 58. The median TIIR was 37.0%, with significant variability among physicians (2-93%). The detection rates for all polyps, adenomas, and sessile serrated polyps were 62.1%, 45.5%, and 7.2%, respectively, and none correlated with TIIR. Intubation of the TI was associated with significantly longer withdrawal times. In a random 10% sample of cases with TI intubation, no clinically significant pathology was found. CONCLUSIONS:There is wide variability in TIIR among endoscopists. Except to provide photodocumentation of exam extent when other images may be difficult to obtain, the lack of correlation between TI intubation and meaningful clinical outcomes together with the associated time costs suggest routine TI intubation during screening colonoscopy may not be warranted.

David Asher Leiman

Associate Professor of Medicine

Dr. Leiman is an Associate Professor of Medicine and gastroenterologist specializing in esophageal diseases and swallowing disorders, such as eosinophilic esophagitis (EoE), motility disorders such as achalasia, and gastroesophageal reflux disease (GERD) as well as its associated complications including Barrett’s esophagus (BE). His busy clinical practice dovetails with his academic focus on health services research, including patient outcomes and clinical quality measurement. He is also a PI for several ongoing multicenter clinical trials investigating novel therapies for EoE and GERD.

Dr. Leiman has mentored numerous medical students, residents, and GI fellows on research and quality improvement projects resulting in research awards, presentations at national meetings, and peer-reviewed publications.

Richard Kevin Wood

Associate Professor of Medicine

I am an academic esophagologist and medical educator.

I am the program director for the Gastroenterology and Hepatology Training Program at Duke.

My clinical area of specialty is in esophageal disorders.  I see patients with a wide range of esophageal problems including: gastroesophageal reflux diseaase (GERD); swallowing disorders; primary esophageal motility disorders including achalasia, esophageal spasm, and jackhammer esophagus; Barrett's esophagus; and Esophageal cancer.

I also practice as a general gastroenterologist and see patients for routine screening colonoscopies.
