Endoscopic Procedures II: Colonoscopy

295
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Assessment of the Rectum and Anus

611
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Area of Science:

  • Gastroenterology
  • Clinical Research
  • Health Services Research

Background:

  • Adenoma detection rate (ADR) shows significant variability across clinical practices.
  • National estimates for ADR are currently unavailable.
  • Understanding ADR is crucial for colonoscopy quality assessment.

Purpose of the Study:

  • To determine the national average ADR in the US.
  • To investigate the variability of ADR over time.
  • To identify factors associated with ADR in a large patient cohort.

Main Methods:

  • Analysis of 2,646,833 colonoscopies from the GI Quality Improvement Consortium registry (2014-2018).
  • Inclusion of adults aged 50-89 years.
  • Utilized hierarchical logistic models to assess factors influencing ADR.

Main Results:

  • The average ADR was 36.80% (SD 10.21), with higher rates in men (44.08%) than women (31.20%).
  • The national average ADR, adjusted to the US population, was 39.08%.
  • A significant increase in ADR was observed from 33.93% in 2014 to 38.12% in 2018.

Conclusions:

  • The national average ADR in the US is approximately 39.05% and has demonstrated an upward trend.
  • Findings provide a benchmark for ADR and highlight temporal improvements.
  • Further research can explore specific factors contributing to ADR variations.
