RESUMO
OBJECTIVE: Gastrostomy tubes (G-tubes) provide long-term feeding assistance to children with severe feeding dysfunction. Although there are a host of complications that occur at home with current pediatric G-tube feeding, their prevalences and outcomes remain relatively unstudied. This study aims to identify and describe such complications. METHODS: A dual-round survey was administered to 98 participants through the Feeding Tube Awareness Foundation, a 501(c)(3) organization that supports parents and caretakers of G-tube-fed children. Information was collected broadly regarding G-tube complications, causes, and attitudes toward such complications. RESULTS: Infection (56%), itching/irritation/redness (52%), and leakage (51%) were the leading G-tube related complications. The average time that G-tubes were replaced was 3.4 ± 1.2 months as compared to the typical recommended period of up to 6 months. Of the caretakers who had not experienced G-tube displacement, 7.9% wanted to see a change in current G-tubes to address the issue, compared with 75% of those who had experienced displacement. This 67.1% differential in caretakers' attitudes toward G-tubes based on their prior experience with a particular complication was the largest gap among all other listed complications. CONCLUSIONS: G-tube complications are prevalent and varied. A sizable portion of G-tube users experience complications severe enough to require intervention. Of these, G-tube displacement is particularly critical and frequently precedes other prevalent complications, namely gastric leakage, infection, and tissue granulation.

Gastrostomy tubes (G-tubes) are the gold standard for feeding assistance for children with feeding dysfunction. Current G-tubes pose complications that interrupt the delivery of feed, including tube displacement and difficulty of at-home use. This study details an alternative, spoke-based, double-lumen G-tube design and preliminary validation of its function and usability. Pull force testing was performed on spoke G-tube models across three sizes and two classifications (hard/soft). Preliminary models were evaluated against market standards. Though the pull force of the spoke model was found to be lower than that of both market standards, hard modifications to the spoke model improved retentive force. Ease of use was tested amongst users unfamiliar with G-tube placement. The spoke design required 12.3 ± 4.7 s to deploy, less than half the time required for market standards. However, balloon G-tubes were still perceived to be easiest to use by 70% of participants, with indications that a spoke design may be easier to use if sized similarly to current G-tubes, with auxiliary improvements to factors such as grip. While there is a need for improvements in the material properties and manufacturing of the proposed design, this study provides early validation of the potential to address complications of existing G-tubes.
