Retrospective review of the outcome of endoscopic ultrasonography-guided gastroenterostomy: a single centre result

Aims Endoscopic ultrasonography-guided gastroenterostomy (EUS-GE) was one of the emerging methods to treat gastric outlet obstruction (GOO). The aim of this study was to review the outcome of EUS-GE.

Methods This was a single-centre retrospective study of consecutive patients undergoing EUS-GE for gastric outlet obstruction (GOO). The primary end point was the rate of technical success (successful placement of stent). The secondary end points were the rate of clinical success (one-point improvement in gastric outlet obstruction score within three day), adverse event, the rate of unplanned reintervention within one year and the possible factors affecting technical or clinical success.

Results Between Sep 2017 and Aug 2024, 65 EUS-GE procedures were included. It included 40 male and 25 female with mean (+ /-SD) age (year) of 68.23+/- 12.71. 61(93.85%) cases presented with GOO were due to malignancy with palliative treatment intent. 53 (81.54%) cases presented with complete obstruction that endoscope not able to pass, with 40 (61.54%) cases had the obstruction at duodenum. 27 (41.54%) cases performed EUS-GE with double balloon occluder (E-PASS) technique, while the remaining 38 (58.46%) cases was performed using the free hand direct puncture technique with the use of saline infusion. Technical success rate was 96.92% and clinical success rate was 98.46%. 2 (3.08%) early adverse events were found to be related to stent puncture. Unplanned reintervention due to recurrent GOO was performed in 4 (6.15%) cases. No factors were found to have a significant result that affect the technical or clinical success.

Conclusions Endoscopic ultrasonography-guided gastroenterostomy is a feasible method to treat gastric outlet obstruction.
