Surgical Gastrostomy in Pediatric Patients Undergoing Cardiac Surgery.

BACKGROUND Practices of performing gastrostomy tubes vary across institutions for patients undergoing cardiac surgery. We aim to elucidate the outcomes of gastrostomy and the duration of feeding assistance in these patients. MATERIALS AND METHODS Patients undergoing cardiac surgery (CS) at our institution from 2013 to 2017 were retrospectively reviewed using the Society of Thoracic Surgery database. A cohort of non-CS patients undergoing gastrostomy tube (g-tube) placement from 2013 to 2015 was used as control. Technical complications and postoperative feeding intolerance were analyzed. Duration of need for g-tube was also analyzed in patients undergoing CS. RESULTS The CS group had 144 patients, and the non-CS group had 677 patients. CS patients had a higher incidence of feeding intolerance (18.8% versus 5.6%, P < 0.001) and took longer to attain full feeds (median of 2 versus 1 d, P < 0.001), and this was confirmed on propensity matched analysis. In addition, technical g-tube complications were similar in the two groups. No mortality in CS was attributed to the g-tube. 58% of patients undergoing CS were able to wean from g-tube feeding by 6-12 mo after g-tube placement. CONCLUSIONS G-tube placement in patients undergoing CS by any technique is safe without increased complications. A significant portion of these patients was able to wean off supplemental enteral feeding assistance by a year after g-tube placement.
