Intussusception

Intussusception is a serious gastrointestinal condition characterized by the telescoping of one segment of the intestine (the intussusceptum) into an adjacent, more distal segment (the intussuscipiens). This causes mechanical bowel obstruction, venous and lymphatic congestion, and, if untreated, arterial compromise leading to intestinal ischemia, necrosis, and perforation.

• Pediatric (Idiopathic): Up to 90% of pediatric cases have no identifiable lead point. It is often linked to viral infections (e.g., adenovirus) causing hypertrophy of Peyer's patches in the terminal ileum.
• Pathological Lead Points: Meckel's diverticulum, intestinal polyps, duplication cysts, Henoch-Schönlein purpura hematomas, or lymphoma.
• Adult Etiology: Rare (~5% of cases). Almost always secondary to a pathological lead point, primarily benign or malignant neoplasms (e.g., adenocarcinoma, lipoma).

The telescoping process begins when a segment of the bowel is swept forward by normal peristaltic activity. As the intussusceptum invaginates into the intussuscipiens, it pulls its mesentery along. This constricts mesenteric blood vessels, causing venous obstruction, edema, mucosal ischemia, and hemorrhage. The resulting mucosal sloughing, mixed with mucus, creates the classic "currant jelly" stool. Unrelieved pressure leads to arterial insufficiency, tissue necrosis, peritonitis, and bowel perforation.

• Age: Predominantly occurs in infants aged 3 to 36 months; it is the most common cause of bowel obstruction in this age group.
• Gender: Male-to-female ratio is approximately 3:2.
• Incidence: Highly seasonal, often peaking during seasons with high rates of gastroenteritis.

• Age (3 months to 3 years)
• Male sex
• Recent viral gastrointestinal or upper respiratory tract infection
• Anatomical abnormalities (e.g., Meckel's diverticulum, polyps)
• Celiac disease or cystic fibrosis

• Vital Signs: Tachycardia, tachypnea, fever (late stage), hypotension (shock).
• Inspection: Abdominal distension, lethargy, or pallor.
• Palpation: Sausage-shaped mass in the right upper quadrant or epigastrium; emptiness in the right lower quadrant (Dance’s sign). Guarding or rigidity indicates peritonitis.
• Auscultation: Hyperactive bowel sounds early on, progressing to absent bowel sounds.

• Abdominal Ultrasound: The diagnostic gold standard. It features a high sensitivity and specificity (>98%). Typical findings include the "target" or "doughnut" sign on transverse views and the "pseudokidney" sign on longitudinal views.
• Abdominal Plain Radiograph: Shows signs of bowel obstruction (dilated bowel loops, air-fluid levels) or free air under the diaphragm in cases of perforation.
• Contrast or Air Enema: Both diagnostic and therapeutic. Shows a classic "claw sign" or "filling defect."

• Gastroenteritis: Presents with diarrhea and fever, but lacks paroxysmal pain cycles and a palpable mass.
• Acute Appendicitis: Pain is localized to the right lower quadrant, is constant, and typically lacks the intermittent colicky nature of intussusception.
• Volvulus: Rapid progression of bilious vomiting, identified by a "whirlpool sign" on ultrasound or malrotation on upper GI contrast series.

• Bowel necrosis
• Intestinal perforation
• Peritonitis
• Sepsis and septic shock
• Recurrent intussusception

• Children: Excellent if diagnosed and treated early. Mortality is <1% with timely intervention. Recurrence rates range from 5% to 10% after successful non-operative reduction.
• Adults: Prognosis depends heavily on the nature of the underlying lead point (e.g., benign vs. malignant tumor).

No definitive primary prevention exists for idiopathic pediatric cases, though monitoring post-rotavirus vaccination is advised. Prompt recognition of clinical signs is key to secondary prevention of ischemic complications.
