Insights
Anti-adhesive barriers may help prevent adhesional small bowel obstruction (ASBO) in pediatric abdominopelvic surgery. However, current evidence is limited by study bias and heterogeneity, necessitating further research.
Area of Science:
- Pediatric Surgery
- Gastrointestinal Surgery
- Surgical Innovation
Background:
- Adhesional small bowel obstruction (ASBO) is a significant concern following pediatric abdominopelvic surgery.
- The effectiveness of anti-adhesive barriers in preventing ASBO in children remains unclear.
Purpose of the Study:
- To review the current literature on the efficacy of anti-adhesive barriers in preventing ASBO in pediatric patients.
- To evaluate the utility of these barriers in pediatric populations undergoing abdominopelvic surgery.
Main Methods:
- A systematic literature search was conducted across multiple databases including Embase, Medline, Cochrane Central, and WHO ICTRP.
- Key outcome measures included ASBO, overall complications, re-operation rates, and surgical site infections.
Main Results:
- Analysis of two studies (912 patients) indicated that anti-adhesive barriers significantly reduced the risk of ASBO (OR 0.39).
- Insufficient evidence exists to support a benefit in reducing overall postoperative complications or surgical site infections.
Conclusions:
- Anti-adhesive barriers show potential for preventing ASBO in pediatric open abdominopelvic surgery.
- However, findings are limited by moderate-to-high risk of bias, small sample sizes, and clinical heterogeneity, requiring further prospective validation.
Background And Aims:
The efficacy of anti-adhesive barriers in preventing clinically significant adhesional small bowel obstruction (ASBO) in the pediatric population is poorly defined. This review seeks to evaluate the utility of anti-adhesive barriers in pediatric populations undergoing abdominopelvic surgery.
Methods:
A literature search was performed on Embase, Medline, Cochrane Centra,l and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) on 20 August 2024. Our main outcome measures included ASBO, total complications, return to theater and surgical site infection.
Results:
A total of three studies were included in this review; however, two studies were published from the same group and institution. Separate analyses were performed due to the potential for overlapping cohorts. Analysis of two studies involving 912 patients comparing anti-adhesive barriers (n = 462) to control (n = 440) suggested that anti-adhesive barriers reduced the risk of ASBO compared with control (OR 0.39, 95% CI 0.19-0.84, p = 0.02). There is insufficient evidence to suggest that anti-adhesive barriers were superior to control in reducing overall postoperative complications (OR 0.81, 95% CI 0.41-1.58, p = 0.63), surgical site infection (OR 0.95, 95% CI 0.35-2.57, p = 0.09).
Conclusion:
Anti-adhesive barriers may have a role in the prevention of ASBO in pediatric populations undergoing open abdominopelvic surgery. However, this occurs on the background of moderate to high risk of bias, small sample size, and high clinical heterogeneity with poor control for confounders. Further prospective research is required to further validate these effects.
