Percutaneous endoscopic gastrostomy vs surgical gastrostomy in infants with congenital heart disease

Gastrostomy tube placement in congenital cardiac surgery: a multi-institutional database study

INTRODUCTION

Neonates and infants who undergo congenital cardiac surgery frequently have difficulty with feeding. The factors that predispose these patients to require a gastrostomy tube have not been well defined. We aimed to report the incidence and describe hospital outcomes and characteristics in neonates and infants undergoing congenital cardiac surgery who required gastrostomy tube placement.

MATERIALS AND METHOD

A retrospective review was performed on patients undergoing congenital cardiac surgery between October 2015 and December 2020. Patients were identified by International Classification of Diseases 10th Revision codes, utilising the performance improvement database Vizient® Clinical Data Base, and stratified by age at admission: neonates (<1 month) and infants (1-12 months). Outcomes were compared and comparative analysis performed between admissions with and without gastrostomy tube placement.

RESULTS

There were 11,793 admissions, 3519 (29.8%) neonates and 8274 (70.2%) infants. We found an increased incidence of gastrostomy tube placement in neonates as compared to infants following congenital cardiac surgery (23.1% versus 6%, p = <0.001). Outcomes in neonates and infants were similar with increased length of stay and cost in those requiring a gastrostomy tube. Gastrostomy tube placement was noted to be more likely in neonates and infants with upper airway anomalies, congenital abnormalities, hospital infections, and genetic abnormalities.

DISCUSSION

Age at hospitalisation for congenital cardiac surgery is a definable risk factor for gastrostomy tube requirement. Additional factors contribute to gastrostomy tube placement and should be used when counselling families regarding the potential requirement of a gastrostomy tube.

Outcomes of Gastrostomy Tubes in Newborns With Congenital Heart Disease and Comparison of Techniques

INTRODUCTION

Gastrostomy tube (GT) placement for enteral access is one of the most common procedures for infants with numerous conditions such as congenital heart disease (CHD). Discrepancies in the literature exist regarding outcomes of newborns with CHD undergoing GT placement. This study sought to characterize postoperative outcomes and readmission complications in this patient population.

METHODS

The Nationwide Readmission Database was queried from 2010 to 2014 for all newborns who underwent GT placement during their index hospitalization. Newborns with or without CHD other than an isolated atrial or ventricular septal defect were compared using standard statistical tests. A propensity score-matched analysis was performed among newborns with or without CHD using > 100 covariates.

RESULTS

Seven thousand seven hundred thirty six patients underwent GT placement. Newborns with CHD (27%) more frequently underwent open GT (59% versus 55%) and less frequently underwent laparoscopic (17% versus 19%) or percutaneous (24% versus 26%) GT placement compared to those without CHD, P = 0.043. GT-related complications on index admission were similar between groups (7% versus 7%, P = 0.770). Newborns with CHD had higher overall readmission rates (39% versus 31%), more GT-related readmission complications (7% versus 3%), and higher readmission costs ($35,787 versus $20,073) compared to newborns without CHD, all P < 0.001. Laparoscopic GT was associated with the lowest rate of GT-related complications (0%) and overall readmission rates (27%) compared to open or percutaneous endoscopic gastrostomy (all P < 0.001).

CONCLUSIONS

Compared to newborns without CHD, newborns with CHD had higher rates of overall readmissions, readmission costs, and GT-related complications on readmission. The laparoscopic GT approach was underused despite fewer complications and readmissions.

Gastrostomy Button Placement in Infants With Cyanotic Versus Acyanotic Congenital Heart Disease

BACKGROUND

Infants with congenital heart disease (CHD) may exhibit increased metabolic demands, and many will undergo placement of a gastrostomy to achieve adequate nutritional intake. There is a paucity of data, however, comparing the operative risks and overall complications of gastrostomy placement in cyanotic versus acyanotic infants with CHD. We hypothesized that patients with cyanotic CHD would have a higher rate of gastrostomy-associated complications than infants with acyanotic CHD.

METHODS

We retrospectively reviewed patients who underwent gastrostomy button placement after cardiac surgery for CHD between 2013 and 2018. Patients were stratified into cyanotic CHD and acyanotic CHD cohorts. Patient data were extracted from the Society of Thoracic Surgeons database and merged with clinical data related to gastrostomy placement and complications from chart review. Unadjusted analyses were used to find covariates associated with cyanotic CHD and acyanotic CHD, using a t-test or Wilcoxon rank-sum test for continuous data, depending on normalcy, and χ² or Fisher's exact tests for categorical data depending on the distribution.

RESULTS

There were 257 infants with CHD who underwent gastrostomy placement during the study period, of which 86 had cyanotic CHD. There were no significant differences in baseline weight or preoperative albumin levels between the two groups. Patients with cyanotic CHD had a lower incidence of comorbid syndromes (P = 0.0001), higher Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery scores (P < 0.0001), and higher postoperative mortality rate (P = 0.0189). There was a higher rate of granulation tissue formation in patients with acyanotic CHD (48.5% versus 22.1%, P < 0.0001). There were no differences in other gastrostomy button-related complications, including leakage, wound infection, or dislodgement.

CONCLUSIONS

Patients with acyanotic CHD demonstrated a higher incidence of granulation tissue. We found no difference in gastrostomy-specific complication rates between the two groups, with the notable exception of granulation tissue formation. Based on this study, the diagnosis of cyanotic CHD does not increase the risk of gastrostomy-related complications.

A comparison of laparoscopic gastrostomy tubes and percutaneous endoscopic gastrostomy in infants: results from a single institution

BACKGROUND/PURPOSE

Laparoscopic gastrostomy (LG) and percutaneous endoscopic gastrostomy (PEG) are two common methods for gastrostomy feeding tube placement in children. There have been limited studies evaluating these surgical interventions in infants under 12 months of age.

METHODS

This study is a retrospective review of 186 patients who underwent either LG or PEG placement over a 5-year period at a single institution. The primary outcome for this study was the complication rate between the two groups.

RESULTS

Of 186 patients who underwent gastrostomy tube placements, n = 130 patients comprised the PEG cohort, and n = 56 made up the LG cohort. The demographics of the two cohorts were comparable in weight, age, and co-morbidities. The overall complication rate was 29.6% The breakdown of 31.5% complications in the PEG group vs. 25% in the laparoscopic group was not statistically different. However, the PEG group did have significantly more patients who required general anesthetic for additional procedures related to G tube placement.

CONCLUSION

Laparoscopy and endoscopy are both acceptable options for gastrostomy tube placements in infants. However, this study identifies that PEG placements are associated with significantly increased risk for the need of additional procedures requiring general anesthesia in this patient population.

Gastrostomy tubes appear to be safe following pediatric orthotopic heart transplant

BACKGROUND

Gastrostomy tube (GT) placement is a common pediatric surgical procedure typically indicated for oral aversion. This may develop in patients with congenital heart disease (CHD) who require an orthotopic heart transplant (OHT). The safety profile of GT placement in OHT patients who are immunosuppressed is unknown. Given the potential increased risk of wound site complications on a patient receiving immunosuppression, we sought to determine the safety profile of GT placement in pediatric patients with OHT.

MATERIALS AND METHODS

We performed a retrospective case series of all pediatric OHT recipients who subsequently underwent GT placement from January 1, 2009, to August 1, 2018, at the University of Virginia Children's Hospital. Major GT complications of wound breakdown, wound infection, peristomal GT leakage, ileus, or persistent emesis, and minor GT complication including the presence of granulation tissue are reported.

RESULTS

Six patients who had a pediatric OHT subsequently underwent GT placement over the study period. There were no major 30-day or 90-day GT complications. One patient had excessive granulation tissue at their GT site. There were no accounts of acute kidney injury, urinary tract infection, sepsis, or pneumonia.

CONCLUSION

Gastrostomy tube (GT) placement appears to be safe in pediatric OHT patients who are on immunosuppressive medications and unable to feed orally. This is the first study documenting the safety profile of GTs in pediatric OHT patients and may aid clinicians to make decisions regarding this intervention.
