Summary
Computed tomography (CT) effectively diagnoses colonic obstruction with 96% sensitivity. This imaging technique is a satisfactory alternative to traditional contrast enema (CE) for evaluating patients with suspected bowel obstruction.
Area of Science:
- Radiology
- Gastroenterology
- Abdominal Imaging
Background:
- Colonic obstruction is a significant clinical concern.
- Accurate diagnosis and evaluation are crucial for patient management.
- Traditional diagnostic methods have limitations.
Purpose of the Study:
- To assess the diagnostic accuracy of computed tomography (CT) for suspected colonic obstruction.
- To compare CT performance against gold standards like surgery and endoscopy.
- To evaluate CT as a potential alternative to contrast enema (CE).
Main Methods:
- Prospective evaluation of 75 patients with suspected colonic obstruction using CT.
- Comparison of CT findings with surgical, endoscopic, or clinical outcomes.
- Direct comparison between CT and contrast enema (CE) in a subset of patients.
Main Results:
- CT demonstrated high sensitivity (96%) and specificity (93%) in diagnosing colonic obstruction and pseudo-obstruction.
- CT accurately localized the obstruction site in 94% of cases.
- Contrast enema (CE) showed lower sensitivity (80%) for obstruction detection.
Conclusions:
- Computed tomography (CT) is a satisfactory and accurate imaging modality for evaluating suspected colonic obstruction.
- CT offers advantages over traditional contrast enema (CE) in specific clinical scenarios.
- CT can reliably diagnose, evaluate, and localize colonic obstructions.

01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

01:25Assessment of the Rectum and Anus
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

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...

01:25Endoscopic 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:
01:27Imaging Studies III: Computed Tomography
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
01:29Intestinal Obstruction I: Introduction
Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...
