Malignant gastric outlet obstruction (GOO) requires prompt surgical or endoscopic decompression. Surgery is associated with significant morbidity and mortality. Fortunately, with the evolution of endoscopic palliative techniques such as duodenal self-expandable metal stent (D-SEMS) placement and EUS-guided gastroenterostomy (EUS-GE), gastroenterologists have available alternatives to palliate these patients. This multicenter (7 academic centers) observational study compared and evaluated the technical and clinical success, adverse events, patient survival, and stent failure-free survival rates of D-SEMS versus EUS-GE.
Ninety-seven patients were included in the D-SEMS group and 79 in the EUS-GE group. Pancreatic cancer was the etiology of GOO in 53.4% of patients. Both technical and clinical success rates were similar between the D-SEMS and EUS-GE groups (92.8% vs 93.7% and 83.5% vs 92.4%, respectively). Additionally, the adverse event rates did not differ between the groups (10.3% vs 10.1%); however, 2 patients from the EUS-GE group required surgical management. At 3 months, patients who underwent EUS-GE experienced improved stent patency compared with patients in the D-SEMS group (92.23% vs 80.6%; adjusted hazard ratio, 0.37; P=.033).
