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

Modifiable Preoperative Risk Factors to Mitigate Postoperative Site Infection Following Pediatric Gastrostomy

PURPOSE

There are limited studies assessing modifiable preoperative risk factors for pediatric laparoscopic gastrostomy tubes (LGT) and percutaneous endoscopic gastrostomy (PEG) tubes. We sought to evaluate the effect of demographics and surgical/infectious history on the superficial infection rate following gastrostomy tube (GT) placement.

METHODS

After IRB approval, we conducted a single-institution retrospective cohort study from 2015 to 2021 of pediatric patients undergoing LGT or PEG tube. The primary outcome was cellulitis or abscess formation within 30-days and 90-days postoperatively. Statistical analyses were performed with t-tests, Chi-squared, and logistic regression(p ≤ 0.05).

RESULTS

There were 382 patients, with 181 (47%) LGT and 201 (53%) PEGs. LGT patients were younger (5.9 vs. 12.3 months, p < 0.001) and more likely to be admitted to the neonatal or cardiac intensive care unit prior to their GT. There were similar rates of prior surgical intervention (58% vs. 66%, p = 0.29) and previous infection (37% vs. 38%, p = 0.87) in both LGT and PEG patients. Within 30-days postoperatively, LGT patients had a higher superficial infection rate (12% vs. 6%, p = 0.04). On multivariate regression, Black race (Odds Ratio 0.10, p = 0.03) was protective and prior Staphylococcus colonization (OR 2.35, p = 0.04) increased the odds of infection. In those patients colonized with Staphylococcus, 21% developed a superficial site infection compared to 9% in those not colonized (p = 0.01).

CONCLUSION

These data suggest prior Staphylococcus colonization is a significant risk factor for superficial infection following GT. Further work into preoperative decolonization strategies may provide an avenue to decrease the high infection rate in this common pediatric procedure.

Percutaneous endoscopic gastrostomy tube placement via the introducer technique is safe and effective in children when compared to the laparoscopic technique

PURPOSE

We compare our experience of percutaneous endoscopic gastrostomy, introducer technique (PEG) and laparoscopic technique (LapGT) at a tertiary care pediatric hospital.

METHODS

Isolated PEGs and LapGTs placements were reviewed at our institution from August 2016 through January 2018. Demographics, procedure time, operative charges, and 30-day complications were reviewed. Means of quantitative values were compared using the student's t test. Categorical values were compared using the X² test.

RESULTS

Ninety-three isolated gastrostomy tubes were placed in children aged 2 weeks to 19 years. There were 56 PEGs (60%) and 37 LapGTs (40%), based on surgeon preference. There was no significant difference in demographics between the two groups. Mean operative time for PEG was 59% shorter (14 vs. 33 min, p < 0.001). Operating room charges averaged $4500 less in the PEG group ($11,400 vs. $15,900, p < 0.001). Neither group had complications that required a return to the operating room within 30 days postoperatively. There was no difference in the rate of fundoplication after gastrostomy tube placement. In two cases PEGs were converted to LapGTs after safety criteria for PEG were not met.

CONCLUSION

The PEG introducer technique, when used with clearly defined safety criteria, decreased operative time and cost without compromising safety.

Pediatric Gastrostomy Tube Placement: Less Complications Associated with Laparoscopic Approach

Background: There are few nationwide studies comparing outcomes of open, laparoscopic (LAP), and percutaneous endoscopic (PEG) gastrostomy tube (GT) placement in the pediatric population. Materials and Methods: The Nationwide Readmissions Database from 2010 to 2014 was used to identify patients ≤18 years (excluding newborns) who underwent GT placement. Demographics, hospital characteristics, and outcomes were compared by the GT approach. Results: There were 3278 patients (41% female, age 3 ± 5 years) identified who underwent GT placement (40% open versus 32% PEG versus 28% LAP). Following an open approach, there were higher rates of GT-related complications (10% versus 4% LAP versus 3% PEG) and postoperative gastrointestinal issues (24% versus 12% LAP versus 9% PEG) on index hospitalization, both P < .001. Readmission within 30 days and 1 year were 18% and 43%, respectively. Overall readmission rates were not affected by the GT approach (44% open versus 44% LAP versus 43% PEG, P = .773). However, readmission for GT-related complications was the lowest following the LAP approach (<0.3% versus 2% open versus 2% PEG, P < .001). When those who also underwent fundoplication were excluded, conversion to gastrojejunostomy or jejunostomy (GJ/J) on readmission was higher following open and PEG approaches (4% open versus 2% PEG versus 0% LAP, P = .039). Conclusions: Compared with PEG gastrostomy and open gastrostomy, LAP GT placement appears to have lower index complications and reoperation rates, and at least comparable readmission outcomes. Despite these advantages, LAP GT placement remains underutilized.

Gastrostomy Tube Outcomes Among Surgical and Non-Surgical Services: A Retrospective Review

BACKGROUND

Our objective was to evaluate differences in baseline characteristics, complications, and mortality among patients receiving a gastrostomy tube (GT) by surgical or non-surgical services.

METHODS

We performed a retrospective analysis of adult patients who underwent GT placement from 2014 to 2017 at a single institution. Using bivariate and multivariable analyses, we compared baseline characteristics, complications, and overall 30-day mortality of patients undergoing GT placement with surgical or non-surgical services.

RESULTS

Of the 1339 adults who underwent GT placement, surgical and non-surgical services performed 45% (n = 609) and 55% (n = 730) procedures, respectively. Gastrostomy tube-related complications were similar (29.6% surgical vs 28.8% non-surgical, P = .76). Thirty-day mortality was higher among non-surgical services (23.7% vs 16.5%, P = .004). On multivariable analysis, this was not significant (OR 1.21, 95% CI 0.83; 1.77).

CONCLUSION

Surgical and non-surgical service placement of GTs had equivalent GT-related mortality and complication rates.

Comparing Different Techniques in Children With or Without a Simultaneous Fundoplication: Does the Gastrostomy Technique Matter?

Purpose: To evaluate the results of different gastrostomy techniques and the impact of simultaneous fundoplication. Materials and Methods: The patients who underwent a gastrostomy procedure between 2009 and 2019 in a single tertiary center were evaluated retrospectively. The patients are divided into groups depending on the gastrostomy techniques as open gastrostomy (OG), laparoscopic gastrostomy (LG), percutaneous endoscopic gastrostomy (PEG), and laparoscopy-assisted PEG (LAPEG). Preoperative characteristics and postoperative outcomes are compared among the groups. Results: Two hundred forty-four patients (75, 60, 91, and 18 patients in OG, LG, PEG, and LAPEG groups, respectively) are enrolled in the study. Although rates of minor or major complications did not demonstrate a significant difference among the groups, no major complications were encountered in the LAPEG group, while the lowest minor complications were observed in the PEG group (P > .05). Length of postoperative initiation of enteral feeding and length of hospital stay (LOS) were highest in the OG group (P = .000). Performing a concurrent fundoplication procedure significantly delayed the initiation of enteral feeding and increased the LOS in all of the groups (P < .005). Conclusions: Although PEG is a safe and reproducible technique of gastrostomy in selected patients, LAPEG may expand the boundaries of PEG by reducing the major complication rates. Although simultaneous fundoplication may complicate the perioperative period, it does not have significance on outcomes.

NICU infants who require a feeding gastrostomy for discharge

OBJECTIVE

To determine population data for infants receiving a gastrostomy tube (GT) in our Neonatal Intensive Care Unit (NICU) to better understand the premature infant population at risk for GT prior to discharge.

STUDY DESIGN

We identified all NICU infants born 2015-2016 who received a GT and determined the birth gestational age below which GTs were placed due to oral feeding failure secondary to prematurity-related comorbidities, rather than anomalies or other reasons. Aggregate data were used to compare infants born <30 weeks (w) gestation who received a GT with those who did not.

RESULTS

GTs were placed in 117 infants. More than half of the NICU patients who receive GTs were actually >32 weeks gestation; a cut-off of <30w was a good identifier for those who failed achieving full oral feeds due to prematurity-related problems. Infants born <30w (n = 282) not receiving GTs were discharged at a significantly lower postmenstrual age (36w) and lower weight (2.3 kg) compared with infants who received a GT (49w, 5 kg).

CONCLUSIONS

The population of premature infants born <30w gestation constitute the population of infants at risk for a GT based solely on prematurity.

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.
