BACKGROUND: Gastric peroral endoscopic pyloromyotomy (G-POEM) was introduced for treating refractory gastroparesis. AIM: To present a series of patients focussed on clinical mid-term efficacy and predictive outcomes factors. METHODS: This was a single centre study of 29 patients operated on between January 2014 and April 2016, with disturbed gastric emptying scintigraphy (GES) and/or elevated Gastroparesis Cardinal Symptoms Index (GCSI). The procedures were performed as previously described. The primary endpoint was the efficacy at 3 and 6 months, based on GCSI and symptoms. The secondary endpoints were GES evolution, procedure reproducibility and safety, and identification of predictive factors for success. RESULTS: There were 10 men, 19 women (mean age 52.8±18). The technical success rate was 100% (average 47 minutes). There were two complications managed conservatively: one bleeding and one abscess. The median follow-up was 10±6.4 months. The clinical success rate was 79% at 3 months, 69% at 6 months, with a significant decrease in the mean GCSI compared to pre-operatively (3.3±0.9 vs 1±1.2 and 1.1±0.9 respectively). The GES (n=23) normalised in 70% of cases, with a significant improvement of the mean half emptying time and retention at 2 hours, and a discordance in 21% of the cases. In univariate analysis, diabetes and female gender were significantly associated with risk of failure, but not confirmed in multivariate analysis. CONCLUSIONS: The mid-term efficacy of G-POEM reaches 70% at 6 months. The procedure remains reproducible and safe. Diabetes and female gender were predictive of failure.
