Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy01:26

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 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...

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:
Diverticular Disease of the Colon01:27

Diverticular Disease of the Colon

Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...

Appendicitis-II: Diagnostic Studies and Management

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...
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,...

Multimodality Diagnosis of Mesenteric Ischemia

Published on: July 21, 2023

Area of Science:

  • Radiology and Medical Imaging
  • Gastroenterology
  • Surgical Diagnosis

Background:

  • Small bowel volvulus (SBV) is a surgical emergency requiring prompt diagnosis.
  • Accurate preoperative assessment of SBV is crucial for effective surgical intervention.

Purpose of the Study:

  • To evaluate the diagnostic utility of multiphasic MDCT with 3D CT angiography (CTA) and CT portal venography (CTPV) for small bowel volvulus (SBV).

Main Methods:

  • Retrospective review of nine surgically confirmed SBV cases.
  • Analysis of multiphasic MDCT, including non-contrast and contrast-enhanced scans.
  • 3D CTA and CTPV reconstructions were utilized for detailed anatomical assessment.

Main Results:

  • MDCT revealed characteristic findings such as bowel dilatation, wall thickening, halo appearance, whirl sign, and closed loops.
  • CTA/CTPV demonstrated abnormal courses of the superior mesenteric artery (SMA) and vein (SMV) in most cases.
  • The location, direction, and degree of SBV were accurately determined in all cases using CTA/CTPV, correlating with surgical findings.

Conclusions:

  • Multiphasic MDCT combined with 3D CTA/CTPV is a valuable tool for diagnosing SBV.
  • This imaging modality enables precise preoperative definition of SBV characteristics, guiding surgical management.
