Esophageal Varices-II: Clinical Features and Management01:28

Esophageal Varices-II: Clinical Features and Management

322
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Disorders of Erythrocytes01:27

Disorders of Erythrocytes

2.0K
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...

Inflammatory Bowel Disease I: Ulcerative Colitis

807
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...

Esophageal Varices-I: Introduction01:24

Esophageal Varices-I: Introduction

1.0K
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

978
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,...

Inflammatory Bowel Disease II: Crohn's Disease

876
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...

Area of Science:

  • Gastroenterology
  • Vascular Surgery
  • Endoscopy

Background:

  • Vascular ectasias, including arteriovenous malformations (AVMs), constitute about 3% of lower gastrointestinal bleeding cases.
  • Colonic AVMs typically present as solitary, large, flat, or elevated red lesions during endoscopic examination.

Observation:

  • A rare case of a polypoid, ulcerated AVM in the transverse colon was identified.
  • The patient presented with symptomatic anemia attributed to the colonic AVM.

Findings:

  • The polypoid colonic AVM was successfully resected using endoscopic techniques.
  • Post-resection, the patient's symptoms of anemia resolved, confirming the effectiveness of the intervention.

Implications:

  • This case underscores the rarity of polypoid colonic AVMs, with only 15 previously reported instances.
  • The successful endoscopic management highlights a viable approach for these uncommon gastrointestinal vascular lesions.
  • Further understanding of endoscopic management strategies for rare colonic AVM presentations is warranted.
