Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

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 II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

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 III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

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, unexplained...
Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

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...
Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

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.

Upper GI Series: Barium Swallow01:24

Upper GI Series: Barium Swallow

The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

Summary
This summary is machine-generated.

Underuse of upper gastrointestinal endoscopy was identified in 11.8% of patients with digestive symptoms. This study highlights the need to reduce both overuse and underuse of medical procedures for better healthcare quality.

Area of Science:

  • Gastroenterology
  • Health Services Research

Background:

  • Healthcare cost-reduction efforts may lead to underuse of medical procedures.
  • Previous research in this cohort identified overuse of upper gastrointestinal endoscopy.

Purpose of the Study:

  • To prospectively assess the underuse of upper gastrointestinal endoscopy.
  • To determine the rate and reasons for underuse in a patient cohort.

Main Methods:

  • Formal necessity criteria for endoscopy were established by an expert panel.
  • Outpatients from primary care and an outpatient clinic were consecutively included.
  • Data were collected from 8135 patient visits across two clinical settings.

Main Results:

  • Underuse of endoscopy was identified in 72 patients (11.8%) with upper digestive symptoms.
  • Key reasons for underuse included uninvestigated peptic symptoms and dysphagia.
  • At one-year follow-up, the underuse rate decreased to 5%, similar to overuse rates.

Conclusions:

  • Prospective evidence confirms the existence of medical procedure underuse.
  • Both overuse and underuse of endoscopy were found to be approximately equal (5%) in this cohort.
  • Improving healthcare quality necessitates reducing both overuse and underuse of medical procedures.
