Gastric peroral endoscopic myotomy improves chronic diarrhea in patients with refractory gastroparesis.
Article in Annals of gastroenterology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: The main symptoms of gastroparesis are early satiety, nausea, vomiting and bloating. In our daily practice, we observed some patients presenting with concomitant chronic alteration of stool frequency. The present study describes retrospectively the impact of gastric peroral endoscopic myotomy (G-POEM) on patients presenting refractory gastroparesis and concomitant chronic diarrhea or constipation. Methods: This retrospective study analyzed the clinical course of patients with refractory gastroparesis and concomitant chronic alteration of stool frequency who were consecutively treated with G-POEM between January 2019 and October 2023 in a tertiary referral center. Results: Of 107 patients with refractory gastroparesis treated by G-POEM, 11 (10.3%) patients (mean age 60.4±16.2 years, 64% female) had altered bowel frequency for >6 months without any other underlying disease (diarrhea n=10; constipation n=1). Scintigraphy confirmed delayed gastric emptying in 10/11 (91%) of cases. G-POEM was technically feasible in all patients without adverse events during or after endoscopic treatment. The median follow-up period was 170 days (interquartile range [IQR] 33-1002). In 9/11 (81%) patients, G-POEM achieved clinical success with a mean gastroparesis cardinal symptom index (GCSI) of 3.1 (interquartile range [IQR] 2.7-3.4) before, and 0.9 (IQR 0.7-1.7) after the endoscopic treatment. Normalization of bowel movements after G-POEM was observed in 9/11 (81%) of patients. Two patients had partial symptom improvement (loose bowels, but normal frequency), 1 of them without improvement of GCSI and persistent delayed emptying on scintigraphy. Conclusion: Gastroparesis may present with concomitant chronic diarrhea that improves after endoscopic treatment by G-POEM.
