Esophageal Varices-II: Clinical Features and Management01:28

Esophageal Varices-II: Clinical Features and Management

102
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...

Esophageal Varices-I: Introduction

206
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...

Summary

This study found intestinal hemangiomas in eight horses, primarily in the small intestine. These vascular tumors were often incidental findings in middle-aged to older horses.

Area of Science:

  • Veterinary Pathology
  • Equine Medicine
  • Gastrointestinal Oncology

Background:

  • Intestinal hemangiomas are rare vascular tumors.
  • Previous reports in horses are limited, with no documented cases in the large colon.

Purpose of the Study:

  • To describe the clinicopathological features of intestinal hemangiomas in horses.
  • To report the first case of equine intestinal hemangioma in the large colon.

Main Methods:

  • Retrospective analysis of eight cases diagnosed via postmortem examination or surgical biopsy.
  • Review of histopathological findings and gross lesion descriptions.

Main Results:

  • Eight cases of intestinal hemangioma identified, solely affecting the intestine.
Keywords:

  • Lesions were focal or multifocal, predominantly in the small intestine (jejunum).
  • One case in the left dorsal colon represents the first report in equine large colon; lesions were cavernous type, mural, and incidental.

    • Conclusions:

    • Intestinal hemangiomas in horses are uncommon and typically incidental findings.
    • These vascular tumors can occur in both small and large intestines.
    • Further research may elucidate potential risk factors or clinical significance.
