Background And Aims:
Interventional gastroenterologists typically perform colonoscopies at lower volumes than general gastroenterologists, and we sought to determine whether this disparity affects their overall adenoma detection rates (ADRs). Our study aimed to identify any difference in ADR between interventional gastroenterologists and general gastroenterologists.
Methods:
A retrospective cohort study from January 2020 to January 2023 was performed to determine ADRs for interventional gastroenterologists and general gastroenterologists at a single academic tertiary care center, as well as assessing for other quality indicators of screening colonoscopy.
Results:
We reviewed 9755 screening colonoscopies. On univariate analysis, ADR differed between groups (46.9% vs 41.5%, P = .033), but on multivariate analysis, provider type was not associated with ADR (odds ratio = 0.99; 95% confidence interval, 0.80-1.22; P = .919).
Conclusions:
ADR was similar between interventional and general gastroenterologists after adjustment for patient characteristics, supporting inclusion of interventional gastroenterologists in colorectal cancer screening practices.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
