INTRODUCTION: Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is increasingly used in the setting of malignant gastric outlet obstruction (GOO). However, little is known about the role of primary EUS-GE. The aim of the present study is to compare the outcomes of EUS-GE by using the freehand technique as a first- and second-line approach after enteral stenting (ES). METHODS: This is an observational single-center study using a prospectively collected database. All consecutive patients who underwent an EUS-GE using the freehand technique due to malignant GOO were included. Patients with previous gastric surgery, a wire-guided EUS-GE technique, or those presenting without GOO were excluded. The primary outcome was the clinical success, defined as a solid oral intake at 1 week after the procedure (GOO Score, GOOSS ≥ 2). The secondary outcomes were technical success and adverse event (AE) rates. The impact on nutritional parameters was also assessed. RESULTS: Forty-five patients underwent an EUS-GE for all indications. Finally, 28 patients (mean age: 63 ± 17.2 years, 57.1% male) with (n = 13, 46.4%) and without (n = 15, 53.6%) a previous ES were included. The technical success was achieved in 25 cases (89.3%), with no differences between the two groups (92.3% vs. 86.7%, p = 1). The median limb diameter and procedure time were 27 mm (range:15-48) and 37 min. Overall, clinical success was achieved in 22 cases (88%), with three failures due to AEs (n = 2) or peritoneal carcinomatosis (n = 1). The diet progression was quicker in patients with a previous ES (GOOSS at 48 h, 2 vs. 1, p = 0.023), but the GOOSS at 1 week (p = 0.299), albumin gain (p = 0.366), and BMI gain (0.257) were comparable in the two groups. The AE rate was 7.1%. CONCLUSIONS: EUS-GE achieves a high technical and clinical success in patients with GOO regardless of the presence of a previous ES. Patients with previous ES may have a quicker progression of their diet, but the GOOSS and nutritional status in the long term at 1 week or 1 month are comparable. Primary EUS-GE might require fewer procedures and less discontinuation of chemotherapy to achieve a comparable result. ispartof: CANCERS vol:14 issue:22 ispartof: location:Switzerland status: published |
