Adult intussusception is rare, often linked to underlying pathology. This case highlights an uncommon idiopathic presentation in a 66-year-old man, emphasizing the need for thorough investigation in adult intussusception.
Area of Science:
- Gastroenterology
- Surgical Case Reports
Background:
- Intussusception is well-documented in children but rare in adults (1-5% prevalence).
- Most adult intussusception cases involve an identifiable underlying pathology requiring investigation.
Purpose of the Study:
- To present a rare case of adult intussusception.
- To discuss the diagnostic and etiological considerations in adult intussusception.
Main Methods:
- Case report of a 66-year-old male presenting with anal mass and obstipation.
- Surgical intervention via laparotomy, sigmoid colectomy, and colostomy.
Main Results:
- Sigmoid colon intussusception into the rectum and anus identified during laparotomy.
- Histological findings revealed necrosis and chronic inflammation without an identifiable cause.
Conclusions:
- Adult intussusception typically has an identifiable cause (70-90%), unlike most pediatric cases.
- This case represents an uncommon idiopathic adult intussusception, lacking clear etiological factors despite examination and histology.
