Summary
Pediatric gallbladder polyps (PLG) are rare but manageable. Small, isolated polyps in children can be monitored conservatively, while larger or symptomatic ones may require surgery.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Diagnostic Imaging
Background:
- Gallbladder polyps (PLG) are uncommon in children, with fewer than 20 reported cases.
- High-quality ultrasonography aids in detecting these rare pediatric lesions.
Purpose of the Study:
- To review the management experience of polypoid lesions of the gallbladder (PLG) in pediatric patients.
- To establish evidence-based guidelines for PLG treatment in children.
Main Methods:
- A retrospective multicenter review of pediatric patients with ultrasonographically defined PLG.
- Data collected from 12 pediatric surgery centers between 2006 and 2016.
Main Results:
- Eighteen pediatric patients were analyzed; nine symptomatic patients underwent cholecystectomy with histopathological confirmation of adenomas.
- Nine asymptomatic children with smaller polyps (median 7mm) were monitored non-operatively, with two lesions resolving spontaneously.
- No malignant transformations or new symptoms were observed during follow-up.
Conclusions:
- A conservative management approach, including annual clinical and ultrasound follow-up, is appropriate for small, isolated pediatric PLG.
- Surgical intervention is recommended for pediatric PLG exceeding 10mm or those presenting with symptoms.
- The potential for spontaneous resolution of small pediatric gallbladder polyps supports a watchful waiting strategy.
