Inflammatory Bowel Disease II: Crohn's Disease01:30

Inflammatory Bowel Disease II: Crohn's Disease

205
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory Bowel Disease I: Ulcerative Colitis

159
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Histology of the Small Intestine01:27

Histology of the Small Intestine

584
The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

414
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

328
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory Bowel Disease V: Surgical Management

133
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:

Area of Science:

  • Gastroenterology
  • Radiology
  • Pathology

Background:

  • Diffuse small bowel wall thickening is a common finding with multiple causes.
  • Infiltrative disorders, due to immunologic, neoplastic cells, or substance accumulation, underlie this thickening.
  • Distinguishing between these infiltrative diseases can be challenging due to overlapping imaging appearances.

Purpose of the Study:

  • To provide a comprehensive review of infiltrative small bowel disorders.
  • To organize these disorders by pathophysiologic features.
  • To aid radiologists in recognizing and differentiating these conditions using imaging.

Main Methods:

  • Review of cross-sectional imaging (CT and MRI) findings.
  • Correlation with clinicopathologic features.
  • Organization of disorders based on pathophysiology with case examples.

Main Results:

  • Detailed descriptions of pathologic features, clinical presentations, and imaging findings for common infiltrative small bowel disorders.
  • Illustrative case examples demonstrating characteristic imaging features.
  • Emphasis on ancillary imaging features and clinicopathologic correlation for differential diagnosis.

Conclusions:

  • A thorough understanding of imaging features and clinical context is crucial for diagnosing infiltrative small bowel disorders.
  • Radiologists play a key role in synthesizing information to guide patient workup.
  • This review enhances the ability to differentiate these conditions, improving diagnostic accuracy.
