Background: EUS-guided gastroenterostomy (EUS-GE) is a minimally invasive therapy for the management of gastric outlet obstruction (GOO). EUS-GE has demonstrated excellent short-term efficacy without the risks of surgical bypass. However, there is limited data on follow-up outcomes. In this study, we collected 6-month follow-up data on patients who underwent EUS-GE for benign and malignant etiologies, to aim to show the shift in paradigm in their management algorithm.
Methods: This was a retrospective multicenter study across 7 international centers of consecutive patients undergoing EUS-GE over a 4-year period who were entered in a dedicated registry. Demographic characteristics, procedure-related information, and follow-up data were collected. Primary outcome was the 6-month data on clinical resolution of GOO.
Results: Ninety-one patients were included (71 malignant and 20 benign cases). Technical success was 99% due to high expertise and volume. Clinical success at 48 hours was 97% (88/90) with an average procedure time of 47 minutes and length of stay of 5.86 days. At 3 months, 87 (95.6%) patients had achieved clinical resolution. At 6 months, 48 (53%) subjects were alive, 40 (44%) were deceased, 3 were lost to follow-up (3.3%) and 1 (1%) had a recurrence of GOO. Clinical success at 6 months follow-up was 98% (47/48).
Conclusions: The majority of patients with GOO who undergo EUS-GE showed clinical resolution at 6-month follow-up. Patients with malignant etiology are appropriately palliated during their life span. Further prospective studies are necessary to obtain long-term data regarding EUS-GE for benign etiologies.
