RESUMO

BACKGROUND AND AIMS: Limited data exist concerning the long-term efficiency of gastric peroral endoscopic myotomy (G-POEM) as a treatment of refractory gastroparesis. This study evaluated the 3-year results of G-POEM in patients with refractory gastroparesis. METHODS: This was a prospective multicenter study of all G-POEM operations performed in 2 expert French centers for 46 patients with refractory gastroparesis with at least 3 years of follow-up. RESULTS: Clinical success was 65.2% at 36 months. There was significant improvement in symptom severity. Median Gastroparesis Cardinal Symptom Index decreased from 3.33 to 1.80 (P < .0001), with improvement in all subscales. We created a predictive score concerning G-POEM success (G-POEM predictive score) to which points were assigned as follows: nausea subscale <2: predictive of success, 1 point; satiety subscale >4: predictive of success, 1 point; bloating subscale >3.5: predictive of success, 1 point; percentage of gastric retention at 4 hours on scintigraphy >50%: 1 point. A threshold of 2 was identified by receiver operating characteristic curve analysis with an area under the curve of .825 that predicted clinical success with a sensitivity of 93.3% (95% confidence interval [CI], .77-.99), specificity of 56.3% (95% CI, .33-.77), positive predictive value of 80% (95% CI, .67-.93), negative predictive value of 81.8% (95% CI, .59-1.00), and accuracy of 80.4% (95% CI, .69-.92). Patients with a score ≥2 were significantly more likely to be responders at 3 years than were patients with a score <2 (80% and 18%, respectively; P = .0004). CONCLUSIONS: The clinical success of G-POEM for refractory gastroparesis was 65.2% at 36 months. Our predictive score offers an easy tool that needs to be confirmed in other studies.

RESUMO

BACKGROUND: Both gastric electrical stimulation (GES) and gastric-peroral endoscopic myotomy (G-POEM) can be offered to patients with gastroparesis and predominant nausea and vomiting. The study's aim was to compare GES and G-POEM efficacy on nausea and vomiting scores in patients with gastroparesis. METHODS: Two multicenter cohorts of patients with medically refractory gastroparesis with predominant nausea and vomiting (defined as a score >2 on nausea and vomiting subscale that varied from 0 to 4) were treated either with GES (n = 34) or G-POEM (n = 30) and were followed for 24 months (M). Clinical response was defined as a decrease of ≥1 point in nausea and vomiting subscale without premature exclusion due to switch from one to the other technique before M24. Changes in symptomatic scales and quality of life were also monitored. KEY RESULTS: Patients from both groups were comparable although the mean score of nausea and vomiting subscale was higher in GES (3.0) compared to G-POEM group (2.6; p = 0.01). At M24, clinical response was achieved in 21/34 (61.7%) patients with GES and in 21/30 (70.0%; p = 0.60) patients with G-POEM. Mean scores of nausea and vomiting subscale decreased at M24 in both GES (from 3.0 to 1.6; p < 0.001) and G-POEM (from 2.6 to 1.2; p < 0.001) groups, although there was no difference between groups (difference adjusted from baseline: -0.28 [-0.77; 0.19]; p = 0.24). Likewise, symptomatic and quality of life scores improved at M24 in both groups, without difference according to treatment group. CONCLUSIONS AND INFERENCES: At M24, we did not observe significant difference in efficacy of GES and G-POEM in medically refractory gastroparesis with predominant nausea and vomiting.
