    Background and Aims Gastric neurostimulation (GNS) and gastric peroral myotomy (G-POEM), therapies for refractory gastroparesis, are associated with suboptimal outcomes. We studied the role of G-POEM as a salvage therapy in patients with refractory symptoms after GNS implantation. Methods This was a multicenter, retrospective, matched case-control study. Consecutive patients with a GNS device and who underwent G-POEM as a salvage therapy for clinical failure (cases) and patients without GNS implantation and who underwent G-POEM for refractory gastroparesis (control) between October 2018 and August 2021 were included. The primary outcome was clinical success after G-POEM. Results A total of 123 patients (mean age 45.7 ± 14.7 years; 88 female subjects [72%]) underwent G-POEM therapy during the study: 41 cases and 82 controls. Clinical success was achieved in 66% in the case group and 65% in the control group (P = .311), during a median total clinical follow-up time of 11.8 (interquartile range, 2.4-6.3) months. In the case group, the mean Gastroparesis Cardinal Symptom Index score decreased from 2.8 ± 1.8 to 1.5 ± 1.9 (P = .024), and gastric retention at 4 hours improved from 45% ± 25.8% to 16.6% ± 13.1% (P = .06). The mean delta improvement in the subscales of nausea/vomiting (1.3 ± .6 vs .9 ± 1.1, P = .044) and bloating (1.6 ± 1.3 vs 1.2 ± 1.4, P = .041) were significantly higher in cases than in controls. Conclusions Among patients with refractory symptoms after GNS, G-POEM can be a reasonable salvage therapy to provide further symptomatic relief with evidence of a potential additive effect of both G-POEM and GNS.
