• Intussusception
      • Invagination of one portion of the bowel into itself—proximal portion usually drawn into distal portion by peristalsis.
      • Male-to-female ratio: 2:1 to 4:1
      • Peak incidence – 5 to 12 months
      • Age range: 2 months to 5 years
      • Causes
        • Idiopathic.
        • Viral (enterovirus in summer, rotavirus in winter).
        • A “lead point” (or focus) is thought to be present in older children
        • These lead points can be caused by:
          • Meckel’s diverticulum ,Polyp ,Lymphoma
          • Henoch–Schönlein purpura  ,Cystic fibrosis
      • Signs and symptoms
        • Classic triad:
          • Intermittent colicky abdominal pain
          • Bilious vomiting
          • Currant jelly stool
        • Neurologic signs:
          • Lethargy
          • Shock-like state
          • Seizure-like activity
          • Apnea
        • RUQ mass:
          • Sausage shaped
          • Ill defined
          • Dance’s sign—absence of bowel in right lower quadrant (RLQ)
        • AXR:
          • Paucity of bowel gas
          • Loss of visualization of the tip of liver
          • “Target sign”—two concentric circles of fat density
        • Ultrasound:
          • “Target” or “donut” sign
            • single hypoechoic ring with hyperechoic center
          • “Pseudokidney” sign —
            • superimposed hypoechoic (edematous walls of bowel) and hyperechoic (areas of compressed mucosa) layers
        • Barium enema
      • Treatment
        • Correct dehydration
        • NG tube for decompression
        • Hydrostatic reduction
        • Barium enema:
          • Cervix-like mass
          • Coiled spring appearance on the evacuation film
          • Contraindications:
            • Peritonitis
            • Perforation
            • Profound shock
        • Air enema:
          • Decreased radiation
          • Fewer complications
        • With radiologic reduction: 7–10%
        • With surgical reduction: 2–5%
      • Clinical Pearls :
        • Most common cause of acute intestinal obstruction under 2 years of age.-Intusussception
        • Most common site is ileocolic (90%).
        • Intussusception and link with rotavirus vaccine led to withdrawal of vaccine from the market.
        • Intussusception:
          • Classic triad is present in only 20% of cases.
          • Absence of currant jelly stool does not exclude the diagnosis.
          • Neurologic signs may delay the diagnosis.
        • Barium enema for intussusception is both diagnostic and therapeutic.
        • Rule of threes:
          • Barium column should not exceed a height of 3 feet
          • No more than three attempts
          • Only 3minutes/attempt

    An intussusception is a medical condition in which a part of the intestine has invaginated into another section of intestine, similar to the way in which the parts of a collapsible telescope slide into one another

    Laparoscopic Surgery For Ileal Intussusception In Adult
    This was an acute onset of abdominal pain with obstructive symptoms in 25 years male, ultrasound showing a 15 cm long Ileal intussusception, which was released by laparoscopic technique and an intra Ileal fibromatous lesion excised and ileal rent sutured and procedure completed by Laparoscopic technique.
