Clinical Report: Endoscopic Ultrasound-Guided Transmural Interventions for Afferent Loop Syndrome

Overview

This comprehensive review and meta-analysis evaluates the efficacy and safety of endoscopic ultrasound (EUS)-guided transmural interventions for afferent loop syndrome (ALS). The findings indicate high technical and clinical success rates, with a notable incidence of adverse events.

Background

Afferent loop syndrome is a rare but significant complication following upper gastrointestinal and pancreaticobiliary surgeries, often seen in patients with recurrent malignancy. Traditional management options can be invasive and carry substantial risks, making minimally invasive alternatives like EUS-guided interventions increasingly relevant.

Data Highlights

Key Findings

• Technical success was achieved in 132 out of 134 patients (98.5%).
• Clinical success was reported in 127 out of 134 patients (94.8%).
• The overall adverse event rate was 14.6%, with common events including procedure-related pain and stent misdeployment.
• Electrocautery-enhanced lumen-apposing metal stents were predominantly used in the studies reviewed.
• Follow-up duration varied from 1 to 15 months across the included studies.

Clinical Implications

Clinicians should consider EUS-guided transmural bypass procedures as a minimally invasive option for managing afferent loop syndrome, while remaining aware of the potential for adverse events.

Conclusion

EUS-guided interventions for afferent loop syndrome warrant further investigation through larger comparative studies.
