Insights
Prophylactic anti-reflux surgery during laparoscopic gastrostomy in children is not routinely necessary. A pre-operative pH study helps identify patients who may benefit, avoiding longer operative times and higher conversion rates associated with unnecessary anti-reflux procedures.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Surgical Outcomes
Background:
- Laparoscopic gastrostomy is common for pediatric enteral nutrition.
- The necessity of prophylactic anti-reflux surgery during gastrostomy is debated.
Purpose of the Study:
- To assess the role and impact of prophylactic anti-reflux surgery in children undergoing laparoscopic gastrostomy.
Main Methods:
- Retrospective analysis of 79 children without pre-existing reflux undergoing laparoscopic gastrostomy.
- Comparison of outcomes between gastrostomy alone and gastrostomy with prophylactic anti-reflux surgery groups.
Main Results:
- Prophylactic anti-reflux surgery group had longer operative times and higher conversion rates.
- No major complications in either group.
- De novo reflux occurred in 11.6% of the gastrostomy-alone group, managed conservatively.
Conclusions:
- Routine prophylactic anti-reflux surgery is not indicated.
- Pre-operative pH studies aid in selecting patients for anti-reflux procedures, preventing unnecessary interventions.
- Low rates of de novo reflux after gastrostomy can be managed without surgery.
Aim:
Laparoscopic gastrostomy is a frequently performed procedure in children requiring long-term enteral nutrition. The role of prophylactic anti-reflux surgery during gastrostomy placements is controversial. The current study aims to evaluate the role of prophylactic anti-reflux procedures during gastrostomy placement.
Methods:
A retrospective single-center analysis of all children without reflux receiving laparoscopic gastrostomy from January 2005 through December 2021 was performed. Demographics and clinical outcomes were compared between patients receiving gastrostomy placement alone and patients receiving gastrostomy with prophylactic anti-reflux surgery.
Results:
A total of 79 patients had a confirmed absence of reflux by a 24-h pH/impedance study before operation. Thirty-six of these patients underwent prophylactic anti-reflux surgery (PAR) while 43 received gastrostomy (PG) alone. The operative time and conversion rate were significantly higher in the PAR group (140.5 ± 67.5 vs. 80.2 ± 66.8 min, p = 0.0001 and 8.3% vs. 0%, p = 0.04). There were no major complications in either group. De novo reflux was detected in five patients (11.6%) in the PG group. None of these patients progressed to require anti-reflux surgery.
Conclusion:
The occurrence of de novo reflux after laparoscopic gastrostomy was low and could be managed without anti-reflux surgery. A routine pre-operative pH study is helpful for appropriate patient selection to avoid unnecessary anti-reflux surgery, which lengthens operative time and increases the conversion rate.
