Insights

Multidetector computed tomography accurately diagnoses high-grade intestinal obstruction. This review focuses on closed-loop obstruction, a rare but serious condition requiring precise imaging for timely intervention.

Area of Science:

  • Radiology
  • Gastroenterology
  • Surgical Pathology

Background:

  • High-grade intestinal obstruction necessitates accurate diagnostic methods.
  • Closed-loop obstruction, a subset of small-bowel obstruction, carries a significant risk of vascular compromise.
  • Accurate diagnosis of closed-loop obstruction is crucial due to its potential for severe complications.

Purpose of the Study:

  • To review the multidetector computed tomography (MDCT) imaging features of closed-loop bowel obstruction.
  • To discuss the various underlying etiologies of closed-loop obstruction.
  • To highlight the technical aspects and diagnostic utility of MDCT in identifying closed-loop obstruction.

Main Methods:

  • Review of relevant medical literature and imaging studies.
  • Analysis of multidetector computed tomography (MDCT) findings in cases of closed-loop obstruction.
  • Correlation of imaging findings with underlying causes such as internal hernias, adhesions, and malrotation.

Main Results:

  • Multidetector computed tomography demonstrates high accuracy in evaluating high-grade intestinal obstruction.
  • Specific MDCT findings can identify closed-loop patterns, differentiating them from simple small-bowel obstruction.
  • MDCT effectively visualizes associated pathologies contributing to closed-loop obstruction.

Conclusions:

  • Multidetector computed tomography is an essential imaging modality for diagnosing closed-loop small-bowel obstruction.
  • Understanding MDCT features aids in identifying the cause and extent of obstruction.
  • Prompt diagnosis via MDCT facilitates appropriate management and reduces the risk of vascular impairment.

Imaging 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...
Intestinal Obstruction I: Introduction01:29

Intestinal 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,...
Intestinal Obstruction II: Pathophysiology01:07

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
Assessment of the Rectum and Anus01:25

Assessment 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.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...
Computed Tomography01:10

Computed 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...

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...
