Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

602
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:

Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

870
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

705
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

512
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

2.7K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

548
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Summary

Gastroenterologists and colorectal surgeons show similar adenoma detection rates (ADR) during colonoscopies, even when comparing high-volume endoscopists. This study highlights comparable quality indicators between these specialties for colon cancer screening.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Endoscopy Quality Metrics

Background:

  • Adenoma detection rate (ADR) is a key colonoscopy quality indicator.
  • Prior studies suggest higher ADR for gastroenterologists versus other specialists.
  • Previous comparisons often involved varied colonoscopy volumes for non-gastroenterologists.

Purpose of the Study:

  • To compare ADR between gastroenterologists and colorectal surgeons.
  • To analyze ADR in endoscopists with comparable annual colonoscopy volumes.
  • To evaluate quality indicators in screening colonoscopies at a single institution.

Main Methods:

  • Retrospective chart review of screening colonoscopies.
  • Inclusion of procedures performed by gastroenterologists and colorectal surgeons.
  • Univariate statistical analysis using GraphPad Prism v9.3.0.

Main Results:

  • Overall ADR was not significantly different between gastroenterologists (36.3%) and colorectal surgeons (30.8%).
  • Colorectal surgeons had longer withdrawal times; gastroenterologists collected more specimens.
  • High-volume endoscopists in both groups met established ADR benchmarks.

Conclusions:

  • Colorectal surgeons and gastroenterologists detect adenomas at similar rates.
  • Gastroenterologists removed more non-adenomatous polyps, including hyperplastic and sessile serrated types.
  • No significant difference in ADR was found between high-volume colorectal surgeons and gastroenterologists.
