Insights
Gagging and slow gastric emptying increase the risk of postoperative paraesophageal hernia (PPEH) in children. Small PPEH cases can be managed nonoperatively, while crural plication reduces PPEH incidence but may increase morbidity.
Area of Science:
- Pediatric Surgery
- Gastrointestinal Surgery
- Hernia Repair
Background:
- Postoperative paraesophageal hernia (PPEH) is a potential complication following antireflux surgery in children.
- Identifying risk factors and optimal treatment strategies for PPEH is crucial for improving patient outcomes.
Purpose of the Study:
- To determine key factors contributing to the development of postoperative paraesophageal hernia (PPEH) in pediatric patients.
- To evaluate the effectiveness of different treatment approaches for PPEH.
Main Methods:
- Retrospective analysis of 464 children undergoing primary antireflux operations between 1985 and 1997.
- Comparison of patients with and without PPEH regarding surgical technique (Nissen fundoplication with or without crural plication), patient age, and clinical course.
- Assessment of preoperative corrected gastric emptying in 289 patients using radionuclide studies.
Main Results:
- The incidence of PPEH was 4.5% (21 of 464).
- Patients with PPEH showed a higher prevalence of preoperative gagging (14.3% vs 1.6%) and slow gastric emptying (53% vs 29%).
- Crural plication during Nissen fundoplication reduced PPEH incidence (3% vs 10%) but was associated with esophageal leaks in two cases.
Conclusions:
- Preoperative gagging and slow gastric emptying are significant risk factors for developing PPEH in children.
- Nonoperative management is a viable option for small PPEH.
- While crural plication lowers PPEH rates, it carries a risk of significant morbidity, necessitating careful consideration.
Purpose:
The aim of this study was to determine the important factors in the development and subsequent treatment of postoperative paraesophageal hernia (PPEH).
Methods:
A retrospective analysis was performed in 464 consecutive children (ages 3 days to 18 years) for PPEH after a primary antireflux operation performed at a Children's Hospital and University Hospital between 1985 and 1997. All operations included a crural repair, but the Nissen fundoplication was performed with (n = 162) and without (n = 70) plication of the esophagus to the crus at 3 points. Patients with and without PPEH were compared with respect to the type of antireflux operation, the patient's age at operation, and the preoperative and postoperative clinical courses. A preoperative corrected gastric emptying value was obtained from a radionuclide gastric emptying study in 289 patients. The treatment of PPEH also was examined.
Results:
The incidence of PPEH in our patients was 4.5% (21 of 464). Although there was a lower incidence of PPEH in patients with crural plication compared with patients without crural plication during Nissen fundoplication (5 of 162, 3% v 7 of 70, 10%; P = .035), 2 patients with crural plication had a postoperative esophageal leak. Patients with PPEH had a significantly increased prevalence of gagging before the initial antireflux operation compared with patients without PPEH (3 of 21, 14.3% v 7 of 443, 1.6%; P = .007). A higher prevalence of slow corrected gastric emptying preoperatively also was seen in patients with PPEH compared with patients without PPEH (8 of 15, 53% v 79 of 274, 29%; P = .046). The prevalences of central nervous system disease, young age (<6 months) at initial operation, and a particular type of antireflux operation were not higher in patients with PPEH. Nine patients with a small PPEH treated by simple observation alone subsequently had resolution of symptoms.
Conclusions:
Patients who have gagging or slow corrected gastric emptying before an antireflux operation are at higher risk for a postoperative paraesophageal hernia. Patients with a small postoperative paraesophageal hernia can be treated nonoperatively. Crural plication of the esophagus during Nissen fundoplication reduces the occurrence of postoperative paraesophageal hernia, but also may result in significant morbidity.
