Intussusception
|
What is it?
|
Intussusception occurs when a portion of the intestine folds like a telescope, with one segment slipping inside another segment. It can occur anywhere in the intestines. This causes an obstruction, preventing the passage of food that is being digested through the intestine.
|
Etiology
|
The cause of intussusception is not known. Though rare, an increased incidence of developing intussusception may be seen in children:
· Who have abdominal or intestinal tumors or masses
· Who have appendicitis
|
Occurrence/Epidemiology
|
Children less than 3 years old, can also occur in older children, teenagers, and adults.
· Intussusception occurs more often in boys than girls.
|
Clinical Presentation
(subjective and physical examination)
|
Subjective: Pain, Sudden loud crying, Straining, Draw knees up, Irritable.
|
Objective: red mucus or jelly like stool, fever, lethargic, vomiting bile, diarrhea, sweating, dehydration, abdominal distention or lump.
|
Diagnostic Testing
|
X-Ray: may demonstrate an elongated soft tissue mass with a bowel obstruction proximal to it.
|
Ultrasound: ‘Target Sign’
also known as the doughnut sign or bull’s eye sign. appearance is generated by concentric alternating echogenic and hypoechogenic bands.
|
Upper & Lower GI Series (Barium Swallow & Enema): giving the “coiled spring” appearance
|
3 Differential Diagnosis
(include difference between each differential diagnosis & the main diagnosis)
|
Intussusception:
Pain, sudden crying, red mucus or jelly like stool, fever, lethargic, vomiting bile, diarrhea, sweating, dehydration, abdominal distention or lump.
|
Gastroenteritis: vomiting that are typically nonbilious, often with anorexia, fever, lethargy, and diarrhea.
No jelly like stool
|
Gastric Volvulus: Epigastric pain tenderness and distention, vomiting, bloody diarrhea
No jelly like stool
|
Appendicitis: abdominal pain that has migrated from a periumbilical position to the right lower quadrant.
No jelly like stool or masses.
|
Non-Pharmacologic Management
|
There are currently no nonpharmacological treatments.
|
Pharmacologic Management
|
May fix itself while being diagnosed with barium enema. Air enema (aids in moving intestines back).
Antibiotics if infection present
Surgery: push the telescoped intestine back out. Rare cases a resection of intestines may happen, and stoma created.
|
Follow Up
|
With toleration of diet, patients treated with nonoperative reduction are usually discharged 12-18 hours after the therapeutic enema. After operative reduction, postoperative progress dictates the length of stay.
