Therapeutic Effect of Table Salt on Gastrostomy Granulomas in Pediatric Patients: A Prospective Study.

Abstract

Purpose: Gastrostomy granulomas frequently occur in pediatric patients with gastrostomy tubes, yet there is a notable lack of comprehensive data on the efficacy and safety of various treatment modalities. Commonly used treatments, such as silver nitrate, are often painful and require frequent clinic visits, posing challenges for patients and families. Additionally, research on home-based treatments is limited, despite their potential to offer more convenient and less painful alternatives. This study addresses the need for well-designed comparisons of different treatment options.

Methods: We conducted a prospective, open-label study at the Children's Hospital of San Antonio, enrolling 36 pediatric patients aged 6 months to 17 years with gastrostomy tubes. Patients were randomized into two groups: one treated with topical silver nitrate and the other with table salt, excluding those on chemotherapy or with immunologic disorders. Granuloma sizes were measured at the study's start with blinded physicians analyzing photographs to assess size reduction, and parent satisfaction surveys were conducted to evaluate treatment acceptability and side effects.

Results: The median reduction in granuloma size was significantly greater in the table salt group (3.12 mm) compared to the silver nitrate group (2.25 mm) (Wilcoxon p-value=0.04). Parental satisfaction and confidence were high in both groups, with minor, self-limited skin irritation reported as a side effect.

Conclusion: The study suggests that table salt could be a feasible, non-inferior, and cost-effective alternative to silver nitrate for treating gastrostomy granulomas in pediatric patients. Further research with a larger sample size is necessary to validate these findings.
