Summary

Adult intussusception caused by an inverted Meckel's diverticulum is rare. Prompt surgical intervention, prioritizing intestinal preservation, leads to favorable outcomes for this challenging condition.

Area Of Science

Gastroenterology
Surgical Case Report

Background

Ileum-ileum-colon intussusception is a rare form of intussusception.
Adult intussusception and Meckel's diverticulum are uncommon, with few documented cases of Meckel's diverticulum inversion causing ileum-ileum-colon intussusception in adults.

Purpose Of The Study

To report a rare case of ileum-ileum-colon intussusception in an adult.
To highlight the diagnostic and surgical challenges associated with this condition.

Main Methods

A 33-year-old male presented with chronic, intensifying abdominal pain.
Computed tomography (CT) scan suggested intussusception secondary to a small intestinal lipoma.
Emergency laparotomy revealed an inverted Meckel's diverticulum as the lead point for intussusception.

Main Results

Surgical resection of the Meckel's diverticulum, terminal ileum, and cecum was performed with ileum-colon anastomosis.
The patient was discharged on postoperative day 7 with no complications.
One-month follow-up showed no discomfort and normal bowel function.

Conclusions

Adult ileum-ileum-colon intussusception secondary to inverted Meckel's diverticulum is exceedingly rare and difficult to diagnose preoperatively.
Prompt surgical intervention with an emphasis on preserving intestinal length is crucial for favorable outcomes.
Surgical reduction of intussusception should be attempted first, prioritizing intestinal viability.
