Insights

Adult intussusception is rare and presents insidiously, often requiring surgical intervention due to a lead point. This case highlights jejunal intussusception in a young adult, emphasizing the need for prompt diagnosis and surgical management.

Area of Science:

  • Gastroenterology
  • Surgical Pathology

Background:

  • Intussusception is common in children but rare in adults.
  • Adult intussusception often presents with non-specific, insidious symptoms, unlike the acute presentation in children.
  • Unlike idiopathic causes in children, adult intussusception typically involves an underlying pathology (lead point).

Observation:

  • This report details a case of jejunal intussusception in a 30-year-old male.
  • The patient presented with symptoms suggestive of intussusception, necessitating further investigation.
  • A computed tomography (CT) scan revealed characteristic findings of intussusception.

Findings:

  • Adult intussusception diagnosis can be challenging due to subtle signs and symptoms.
  • The underlying cause in adults is frequently a 'lead point', necessitating different treatment strategies compared to children.
  • Jejunal intussusception in this adult case required surgical intervention, specifically exploratory laparotomy and small bowel resection.

Implications:

  • Prompt diagnosis and surgical management are crucial for adult intussusception.
  • Understanding the varied causes of lead points in small versus large bowel intussusception is important for surgical planning.
  • This case underscores the importance of considering intussusception in adults presenting with abdominal pain, even with atypical symptoms.

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...

Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

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 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:

Acute Pancreatitis I: Introduction01:25

Acute Pancreatitis I: Introduction

Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
