Bowel intussusception in adult: Prevalence, diagnostic tools and therapy

Area of Science:

• Gastroenterology
• Surgical Pathology

Background:

• Intussusception is the invagination of one bowel segment into an adjacent one.
• While common in children, adult intussusception is rare and typically has an identifiable underlying cause.

Purpose of the Study:

• To review the clinical presentation, diagnostic approaches, and management strategies for adult intussusception.
• To highlight the distinct etiology and characteristics of intussusception in adults compared to pediatric cases.

Main Methods:

• Literature review of adult intussusception cases.
• Discussion of diagnostic modalities including imaging and endoscopy.
• Analysis of various surgical and non-surgical treatment options.

Main Results:

• Adult intussusception is frequently associated with identifiable causes, such as tumors or adhesions.
• Symptoms can be nonspecific, mimicking other acute abdominal conditions.
• Diagnosis often relies on advanced imaging techniques.

Conclusions:

• Adult intussusception requires a high index of suspicion, especially when common causes of acute abdomen are excluded.
• Understanding the specific etiologies and presentation in adults is crucial for timely diagnosis and effective management.
• This review provides a comprehensive overview for clinicians managing this rare condition.
