Operative Complications Following Gastrostomy Tube Placement After Cardiac Surgery During Infancy

Gastrostomy tube (GT) placement is common in infants following repair of congenital heart defects. We aimed to determine rate of operative complications and predictors of short-term GT use to counsel parents regarding the risks and benefits of GT placement.

We reviewed infants aged <1 y with congenital heart disease who underwent GT placement after cardiac surgery between 2018 and 2021. Demographics and clinical data were collected and analyzed. Comparisons were made between infants who required the GT for more than 1 y and those who required the GT for less than 1 y.

One hundred thirty three infants were included; 35 (26%) suffered one or more complication including wound infection (4, 3%), granulation tissue (3, 2%), tube dislodgement (10), leakage from the tube (9), unplanned emergency department visit (15), and unplanned readmission (1). Thirty-four infants used the GT for feeds for 1 y or less (26%) including 17 (13%) who used it for 3 mo or less. Fifty-six infants had their GT removed during the study period (42%), 20 of whom required gastrocutaneous fistula closure (36%). Thirty-three infants had a GT placed on or before day of life 30, 17 (52%) used the GT for less than 1 y, and 10 (31%) used it for 3 mo or less.

GT placement is associated with a relatively high complication and reoperation rate. GT placement in infants aged less than 30 d is associated with shorter duration of use. Risks, benefits, and alternatives such as nasogastric tube feeds should be discussed in the shared decision-making process for selected infants.
