Inflammatory Bowel Disease II: Crohn's Disease01:30

Inflammatory Bowel Disease II: Crohn's Disease

1.5K
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 V: Surgical Management

843
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:

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

1.8K
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,...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

913
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...

Lower GI Series: Barium Enema01:23

Lower GI Series: Barium Enema

2.4K
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...

Inflammatory Bowel Disease I: Ulcerative Colitis

1.4K
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...

Area of Science:

  • Gastroenterology
  • Abdominal Radiology
  • Surgical Pathology

Background:

  • Small and large bowel obstructions represent a significant portion of acute abdominal surgical conditions.
  • Accurate radiologic assessment is vital for timely diagnosis and management.

Purpose of the Study:

  • To outline the radiologic approach to suspected bowel obstruction.
  • To detail key imaging findings for diagnosing and characterizing bowel obstructions.

Main Methods:

  • Review of radiologic imaging techniques for evaluating bowel obstruction.
  • Correlation of imaging findings with clinical presentation and surgical outcomes.

Main Results:

  • Radiologists must answer critical questions regarding obstruction presence, level, cause, and severity.
  • Imaging can differentiate simple from closed-loop obstructions and identify complications like strangulation, ischemia, or perforation.

Conclusions:

  • A systematic radiologic approach is essential for effectively managing patients with bowel obstruction.
  • Comprehensive imaging interpretation aids in surgical planning and improves patient outcomes.
