Objectives: Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is an emerging procedure for gastric outlet obstruction (GOO) as an alternative to endoscopic stent placement in the duodenum or surgery; however, it is technically challenging. This study aimed to evaluate the safety, success rate, and adverse events rate associated with retrieval anchor-assisted EUS-GE.
Methods: Data from patients who underwent retrieval anchor-assisted EUS-GE for malignant and benign GOO were retrospectively analyzed. Patients' clinical and demographic characteristics, procedure time, and success and adverse event rates were recorded.
Results: A total of 10 patients (6 females; mean age 63.2 ± 5.8 years) were included in our study. Nine cases were malignant and one case was benign GOO. Nine patients received retrievable anchor-assisted EUS-GE for GOO. One patient received retrievable anchor-assisted EUS-GE and concurrent EUS-guided hepatogastrostomy due to the biliary obstruction. There were no complications during any of the procedures. The rate of technical and clinical success was 100%.
Conclusions: EUS-GE is a safe and effective procedure for GOO. The retrieval anchor can make EUS-GE easier to perform successfully.
