A comparison of balloon and nonballoon gastrostomy tubes in children

Area of Science:

• Pediatric Gastroenterology
• Medical Device Technology
• Surgical Outcomes

Background:

• Gastrostomy tubes (G-tubes) are crucial for nutritional support in pediatric patients.
• Choosing between balloon and nonballoon G-tube types impacts patient management and resource utilization.
• Understanding comparative outcomes is essential for optimizing G-tube selection.

Purpose of the Study:

• To compare primary outcomes, including emergency interventions and operative procedures, between balloon and nonballoon gastrostomy tubes.
• To evaluate the frequency of interventions required for G-tube maintenance and replacement.

Main Methods:

• Retrospective chart review of 145 pediatric patients over a 5-year period.
• Comparison of emergency room (ER) visits, radiologic interventions, and operative procedures for balloon versus nonballoon G-tube devices.
• Analysis of data including patient demographics, G-tube type, and reasons for intervention.

Main Results:

• Patients with nonballoon G-tubes experienced significantly more ER visits (1.14 vs. 0.48) and required more operative interventions (average 2.55 vs. 0.40) compared to those with balloon G-tubes.
• A higher percentage of nonballoon G-tubes required operative replacement (34.6%) versus balloon G-tubes (0%).
• The majority of patients initially receiving a nonballoon G-tube needed a second operation for device change (95.7%).

Conclusions:

• Balloon-type gastrostomy tubes are associated with fewer emergency room visits and operative interventions compared to nonballoon G-tubes.
• The findings suggest that balloon G-tubes may offer a safer and more cost-effective option for pediatric patients requiring gastrostomy.
• Further research could explore long-term outcomes and patient-reported satisfaction with different G-tube types.
