Background: Infants with congenital heart disease (CHD) often require the placement of a gastrostomy button to ensure proper nutrition. Some also require a Nissen fundoplication (NF) to further improve nutrition capabilities in the setting of reflux, however, the clinical and diagnostic imaging characteristics that support NF are variable. The aims of this study were as follows: (1) identify the factors associated with NF in patients with CHD and (2) determine the incidence of NF complications in patients with CHD.
Methods: All patients with CHD who underwent cardiac repair and subsequent creation of a gastrostomy at a single institution between 6/1/2013 and 9/1/2018 were included. We then identified which patients underwent NF.
Results: Two-hundred fifty-seven CHD patients who had a gastrostomy button placed after CHD repair, with 17% undergoing a simultaneous NF or an NF at a later time. The presence of acyanotic heart disease, neurologic comorbidities, and vocal cord dysfunction was not univariately associated with a higher likelihood of NF. On multivariable model, only prematurity was significantly associated with NF (P = 0.022). Abnormal findings on imaging studies (upper gastrointestinal series, gastric emptying studies, motility studies, upper endoscopies, swallow studies, and pH probe studies) were not associated with an NF (all P's > 0.05). The overall complication rate was 23%.
Conclusions: Prematurity was the only factor associated with an NF. Surprisingly, cyanotic heart disease, neurologic comorbidities, age at first cardiac surgery, and vocal cord dysfunction were not associated with an NF. We identified an area for quality improvement at our institution given the lack of standardized work-up for the NF in this high-risk population.
