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,...
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...
Appendicitis01:19

Appendicitis

Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
Inflammatory Bowel Disease I: Ulcerative Colitis01:27

Inflammatory Bowel Disease I: Ulcerative Colitis

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...
Traumatic Brain Injury l: Introduction01:28

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...
Esophageal Perforation-I: Introduction01:22

Esophageal Perforation-I: Introduction

Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus.

Summary

Traumatic intussusception is rare, especially when caused by an intramural hematoma. This case highlights CT findings of a duodenojejunal hematoma leading to jejunojejunal intussusception in a pediatric patient.

Area of Science:

  • Gastroenterology
  • Pediatric Surgery
  • Radiology

Background:

  • Intussusception is a common cause of bowel obstruction in children.
  • Traumatic intussusception is uncommon, with various potential lead points.
  • Intramural hematomas can rarely serve as the lead point for intussusception.

Observation:

  • A 12-year-old boy presented with symptoms suggestive of bowel obstruction.
  • Computed Tomography (CT) revealed a large intramural hematoma in the duodenojejunal region.
  • The hematoma was identified as the lead point causing a jejunojejunal intussusception.

Findings:

  • CT imaging demonstrated a significant duodenojejunal intramural hematoma.
  • This hematoma acted as the lead point for a secondary jejunojejunal intussusception.

  • The findings underscore the diagnostic utility of CT in identifying rare causes of intussusception.

    • Implications:

    • This case expands the spectrum of known causes for pediatric intussusception.
    • Accurate CT interpretation is crucial for diagnosing traumatic intussusception secondary to intramural hematoma.
    • Understanding this rare etiology aids in appropriate surgical planning and management.
