Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

804
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 IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

795
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...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy01:26

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

460
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
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...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

693
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 III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

931
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 Procedures I: Esophagogastroduodenoscopy

1.4K
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:

Area of Science:

  • Gastroenterology
  • Health Services Research
  • Public Health

Background:

  • Increased insurance coverage has led to greater availability of colonoscopy for average-risk individuals.
  • Changes in insurance benefits prompted an examination of the colonoscopy workforce and practice patterns.

Purpose of the Study:

  • To identify changes in the colonoscopy workforce in South Carolina between 2001 and 2010.
  • To examine shifts in provider types and practice settings for colonoscopies over time and across urban/rural areas.
  • To explore variations in colonoscopy volume by facility and provider type.

Main Methods:

  • Retrospective analysis of all colonoscopy procedures using an all-payer outpatient discharge records database.
  • Data collected from South Carolina between 2001 and 2010.

Main Results:

  • Colonoscopies performed in ambulatory surgery settings increased by 127%, while hospital-based procedures saw a 2% rise.
  • The number of internists and family physicians performing colonoscopies increased by 65% and 212%, respectively.
  • Significant variation in annual colonoscopy volume was observed across specialties, with lower volumes among non-gastroenterologists.

Conclusions:

  • Substantial changes occurred in colonoscopy facilities and physician involvement in South Carolina since 2001, notably in urban counties.
  • Non-gastroenterologists appear to be addressing the demand for colonoscopies in rural areas.
  • The study highlights evolving trends in colonoscopy delivery and workforce utilization.
