RESUMO
BACKGROUND AND AIMS: EUS-guided gastroenterostomy (EUS-GE) is increasingly used for malignant gastric outlet obstruction (GOO) in inoperable patients. However, the impact of EUS-GE on patient quality of life (QoL) has not been evaluated prospectively. METHODS: Consecutive patients with unresectable malignant GOO who underwent EUS-GE between August 2019 and May 2021 at 4 Spanish centers were prospectively assessed using the European Organization for Research and Treatment of Cancer QoL Questionnaire Core 30 at baseline and 1 month after the procedure. Centralized follow-up by telephone calls was undertaken. The Gastric Outlet Obstruction Scoring System (GOOSS) was used to assess oral intake, defining clinical success as a GOOSS ≥2. Differences between baseline and 30-day QoL scores were assessed using a linear mixed model. RESULTS: Sixty-four patients were enrolled, 33 (51.6%) men, with a median age of 77.3 years (interquartile range, 65.5-86.5). The most common diagnoses were pancreatic (35.9%) and gastric (31.3%) adenocarcinoma. Thirty-seven patients (57.9%) presented a 2/3 baseline Eastern Cooperative Oncology Group performance status score. Oral intake was restarted within 48 hours in 61 patients (95.3%), and the median postprocedure hospital stay was 3.5 days (interquartile range, 2-5). The 30-day clinical success rate was 83.3%. A clinically significant increase of 21.6 points (95% confidence interval, 11.5-31.7) in the global health status scale was documented, with significant improvements in nausea and vomiting, pain, constipation, and appetite loss. CONCLUSIONS: EUS-GE relieves GOO symptoms in patients with unresectable malignancy, allowing rapid oral intake and hospital discharge. It also provides a clinically relevant increase in QoL scores at 30 days from baseline. (Clinical trial registration number: NCT04660695.).
