Abstract:
Meckel diverticulum was diagnosed preoperatively as the cause of recurrent rectal bleeding in a 2-year-old child by means of a sodium pertechnetate Tc 99m scan. Although false-negative scans have been reported to occur in approximately 50% of all cases of Meckel diverticulum, the procedure should be considered in any case of unexplained, painless rectal bleeding, especially in pediatric patients.
Insights
A sodium pertechnetate Tc 99m scan diagnosed Meckel diverticulum in a child with rectal bleeding. This scan is valuable for unexplained bleeding in children, despite potential false negatives.
Area of Science:
- Pediatric Surgery
- Diagnostic Imaging
Background:
- Recurrent rectal bleeding in children often presents a diagnostic challenge.
- Meckel diverticulum is a congenital anomaly that can cause significant gastrointestinal issues.
Observation:
- A 2-year-old child presented with recurrent, painless rectal bleeding.
- Preoperative diagnosis was crucial for effective management.
Findings:
- A sodium pertechnetate Tc 99m scan successfully identified Meckel diverticulum as the source of bleeding.
- The scan's utility is highlighted despite a known false-negative rate of approximately 50%.
Implications:
- The Tc 99m scan should be considered in the workup of unexplained pediatric rectal bleeding.
- Early diagnosis of Meckel diverticulum can prevent complications and guide surgical intervention.
