Insights

A rare tumor, myoepithelial hamartoma (MEH), caused intussusception in a 5-month-old infant. Surgical intervention was necessary after hydrostatic reduction failed, highlighting MEH as an unusual cause of pediatric intussusception.

Area of Science:

  • Pediatric Surgery
  • Gastrointestinal Pathology
  • Oncology

Background:

  • Intussusception is a common surgical emergency in infants and children.
  • Hydrostatic reduction is the primary treatment modality for ileo-ileal intussusception.
  • Tumors are an uncommon leading point for intussusception in the pediatric population.

Observation:

  • A 5-month-old female infant presented with ileo-ileal intussusception.
  • Initial management with hydrostatic reduction was unsuccessful.
  • Surgical exploration identified a 1.5 cm tumor as the leading point.

Findings:

  • Histopathological diagnosis confirmed the tumor as a myoepithelial hamartoma (MEH).
  • Myoepithelial hamartomas are rare neoplasms, particularly in pediatric small bowel intussusception.
  • This case highlights an atypical etiology for intussusception in a young child.

Implications:

  • Myoepithelial hamartomas should be considered in the differential diagnosis of pediatric intussusception, especially when standard reduction methods fail.
  • Early surgical intervention may be required for intussusception caused by intraluminal masses.
  • Further research into the occurrence and management of MEH in pediatric intussusception is warranted.

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,...

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...

Histology of the Large Intestine

The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...
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...

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:
