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...
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,...
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...

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:
Esophageal Varices-I: Introduction01:24

Esophageal Varices-I: Introduction

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 summary is machine-generated.

Intestinal volvulus caused death in 18 cetaceans, primarily toothed whales. This condition involves twisting of the intestine, leading to acute illness and often fatal outcomes in marine mammals.

Area of Science:

  • Marine Mammal Pathology
  • Veterinary Medicine
  • Gastroenterology

Background:

  • Intestinal volvulus is a critical gastrointestinal condition.
  • It has been identified as a cause of mortality in various animal species, including cetaceans.
  • Understanding its occurrence in marine mammals is vital for conservation and welfare.

Purpose of the Study:

  • To identify intestinal volvulus as a cause of death in cetaceans.
  • To describe the pathological findings associated with cetacean intestinal volvulus.
  • To explore potential predisposing factors and clinical signs for early diagnosis.

Main Methods:

  • Retrospective case analysis of 18 cetacean deaths attributed to intestinal volvulus.
  • Review of pathological findings from 11 global institutions.
  • Analysis of available clinical histories and gross pathological descriptions.

Main Results:

  • Intestinal volvulus was the cause of death in 18 cetaceans (8 species of toothed whales).
  • Pathological findings included distended, congested, and edematous intestines with associated mesenteric and lymph node lesions.
  • The cranial portion of the intestines was involved in 85% of cases, and predisposing factors were identified in 72% of cases.

Conclusions:

  • Intestinal volvulus is a significant cause of mortality in toothed whales.
  • Clinical signs include acute dullness, and pathological findings are consistent across species.
  • Further research into predisposing factors is crucial for prevention and improved clinical management.
