A recent prospective longitudinal cohort study (J Franken et al. JPGN 2020; 70: e41-47) examined the development of gastroesophageal reflux (GER) in 50 children who underwent gastrostomy tube (GT) placement between 2012-2014.
- GER symptoms were present before and after GT placement: in 44% and 40% respectively.
Among the 25 who underwent pre- and post-operative impedance-pH analysis
- there was not a significant change in acid exposure: 6.2% vs. 6.1%
- there was not a significant change in reflux episodes
- Prior to GT placement, 18 of 25 (72%) had pathologic reflux. Afterwards, 18 of 25 (72%) had pathologic reflux –though this included 4 with new onset reflux and 4 with resolved reflux
My take: This study shows that reflux symptoms and documented reflux are commonplace in children undergoing GT placement. Based on this limited sample size, it appears that GER does not appreciably change following GT placement.
