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 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 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.

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 Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

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 to...
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...

Summary
This summary is machine-generated.

Interactive voice response (IVR) system calls are as effective as nurse calls for improving patient attendance and preparation for endoscopic procedures like flexible sigmoidoscopy (FS) and colonoscopy.

E-Patient Counseling Trial (E-PACO): Computer Based Education versus Nurse Counseling for Patients to Prepare for Colonoscopy

Published on: August 1, 2019

Area of Science:

  • Gastroenterology
  • Health Informatics
  • Patient Education

Background:

  • Effective patient preparation is crucial for the success of endoscopic procedures such as flexible sigmoidoscopy (FS) and colonoscopy.
  • Traditional methods of patient education and appointment reminders often rely on direct human interaction, which can be resource-intensive.

Purpose of the Study:

  • To compare the effectiveness of an interactive voice response (IVR) system with nurse-delivered phone calls in preparing patients for FS and colonoscopy.
  • To assess whether IVR calls could equally ensure patient attendance and adequate preparation for these examinations.

Main Methods:

  • A three-arm randomized controlled trial involving 3610 patients scheduled for FS or colonoscopy.
  • Intervention groups received either a nurse phone call or an IVR system call 7 days prior, or an IVR system call 3 days prior.
  • All calls provided appointment reminders, preparation information, and encouragement.

Main Results:

  • No statistically significant differences were observed in appointment attendance or preparation adherence between the IVR and nurse call groups.
  • A higher proportion of patients in the IVR groups reported neutral perceptions, while more in the nurse call group reported very positive perceptions.
  • The study included 1229 FS and 2381 colonoscopy appointments.

Conclusions:

  • Interactive voice response (IVR) systems are an effective alternative to nurse-delivered calls for ensuring patient attendance and adequate preparation for endoscopic examinations.
  • IVR systems offer a scalable solution for patient preparation in gastroenterology practices.
