Gastric peroral endoscopic pyloromyotomy versus gastric electrical stimulation in the treatment of refractory gastroparesis: a propensity score-matched analysis of long term outcomes.

BACKGROUND : Gastric peroral endoscopic pyloromyotomy (G-POEM) and gastric electrical stimulation (GES) have been reported as treatment options for refractory gastroparesis. In this study, we compared the long term clinical outcomes of G-POEM versus GES in the treatment of such patients. METHODS : We retrospectively evaluated 111 consecutive patients with refractory gastroparesis between January 2009 and August 2018. To overcome selection bias, we used propensity score matching (1:1) between G-POEM and GES treatment. The primary outcome was the duration of clinical response. RESULTS : After propensity score matching, 23 patients were included in each group. After a median follow-up of 27.7 months, G-POEM had a significantly better and longer clinical response than GES (hazard ratio [HR] for clinical recurrence 0.39, 95 % confidence interval [CI] 0.16 - 0.95;
