RESUMEN
PURPOSE: Endoscopic ultrasound-guided gastro-enterostomy (EUS-GE) is a relatively novel technique that has been shown to require less re-intervention than standard endoscopic enteral stenting for gastric outlet obstruction and is less invasive, quicker, and more cost-effective than surgery. This study evaluated the outcomes and safety of EUS-GE in patients treated for gastric outlet obstruction across two Australian centers. METHODS: Retrospective data on demographics, presenting symptoms, disease, endoscopic and clinical outcomes, and safety were collected on all patients who underwent EUS-GE from 2021 to 2022. Descriptive statistics were used to evaluate outcomes and safety and survival were calculated using Kaplan-Meier analysis. RESULTS: Eleven patients underwent EUS-GE during the defined period, 10 of whom had a malignant etiology (median age 73 years, interquartile range [IQR] 13; 63.6% male). Technical success was 90.9%. Of those patients, clinical success (the ability to tolerate at least a full liquid diet during follow-up) was 100%. The median length of hospital stay post-procedure was 6 days (IQR 14 days). No severe adverse events occurred, and one patient (10%) required a repeat endoscopy. Median survival post-EUS-GE was 298 days (95% confidence interval 0-730.1 days) CONCLUSION: EUS-GE is an effective, safe, and durable therapy for patients with gastric outlet obstruction. This study presents Australian data on outcomes and safety that is comparable to international literature. EUS-GE should be considered for patients where local expertise allows.
