The abdominal technetium scan (a decade of experience)

Area of Science:

• Pediatric Surgery
• Diagnostic Imaging
• Gastroenterology

Background:

• Meckel's diverticulum is a common congenital anomaly causing gastrointestinal issues in children.
• Accurate diagnosis is crucial for appropriate surgical management and to avoid unnecessary procedures.

Purpose of the Study:

• To evaluate the diagnostic accuracy of technetium scanning for Meckel's diverticulum in pediatric patients.
• To assess the scan's utility in identifying other gastrointestinal pathologies.

Main Methods:

• Retrospective analysis of 270 children with gastrointestinal symptoms undergoing technetium scanning.
• Correlation of scan findings with surgical exploration and histopathological results.

Main Results:

• Technetium scan identified Meckel's diverticulum in 12 of 26 surgically explored patients (46%) with positive scans.
• The scan detected other surgical lesions in 9 patients and had a 15% false-positive rate (5 patients).
• In patients with negative scans, 2 Meckel's diverticula and 6 other surgical lesions were found upon exploration.

Conclusions:

• Technetium scanning is a reliable tool for detecting Meckel's diverticulum in children, with an estimated detection rate of 80-90%.
• The scan demonstrates high accuracy in excluding Meckel's diverticulum, with over 90% of negative scans correctly ruling out the condition.
