Summary
A new bowel preparation allows for same-day computed tomography (CT) colonography and colonoscopy, regardless of the procedure order. This method effectively tags fecal matter without hindering visualization or causing scope clogs.
Area of Science:
- Gastroenterology
- Radiology
- Medical Imaging
Background:
- Bowel preparation is crucial for both CT colonography and colonoscopy.
- A single preparation suitable for both procedures could streamline patient care and reduce costs.
Purpose of the Study:
- To assess the suitability of a CT colonography bowel preparation for same-day colonoscopy.
- To determine if the preparation works effectively regardless of the procedure sequence.
Main Methods:
- Seventy-five patients underwent colonoscopy after receiving a bowel preparation containing contrast material for fecal tagging.
- Endoscopists evaluated colon cleanliness, dryness, and any impairment from contrast material.
- Patients underwent either CT colonography followed by same-day colonoscopy, or vice versa.
Main Results:
- The contrast material was minimally perceptible and did not impede mucosal visualization or cause endoscope clogging.
- The bowel preparation was well-tolerated by patients.
- Same-day CT colonography and colonoscopy using fecal tagging proved technically feasible.
Conclusions:
- A cost-effective, 1-day bowel preparation with fecal tagging is suitable for both CT colonography and colonoscopy performed on the same day.
- Widespread adoption may be limited by endoscopist preferences and the availability of oral contrast agents.

01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
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 solid...

01:23Lower GI Series: Barium Enema
A Barium Enema, or a lower GI series, is a specialized radiographic examination designed to visualize the lower gastrointestinal tract, specifically the colon and rectum. This procedure is instrumental in diagnosing various conditions such as colorectal cancer, polyps, diverticulosis, and inflammatory bowel disease.
Procedure Details
The examination begins by inserting a lubricated rectal tube into the patient's rectum to administer a radiopaque barium solution. The barium flow is carefully...

01:25Endoscopic 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:
01:26Endoscopic 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...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

01:28Endoscopic 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...
