Subtotal resection of gastric duplication cysts using endoscopic submucosal dissection: A case report.
Article in World journal of gastrointestinal surgery, 2025. 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
backgroundGastric duplication cysts (GDCs) are rare congenital anomalies, and consensus guidelines for their diagnosis and management are currently lacking. We report a rare case of a GDC in a female child presenting as a submucosal tumor in the gastric antrum. Subtotal resection was achieved using endoscopic submucosal dissection (ESD), resulting in complete symptom relief and pathological confirmation. This case demonstrates the therapeutic potential of ESD for intraluminal GDCs and underscores the importance of complete resection for definitive diagnosis. CASE SUMMARY: A 12-year-old girl presented with abdominal distension and pain for > 1 year. Gastroscopy revealed a protruding lesion approximately 30 mm in diameter in the gastric antrum. Superficial biopsies revealed moderate chronic inflammation and intestinal metaplasia. Contrast-enhanced computed tomography showed a mass protruding into the gastric lumen with homogeneous cyst wall enhancement. Endoscopic ultrasonography identified a hypoechoic mass originating from the muscularis mucosa. The patient underwent ESD for diagnosis and symptom relief. Intraoperatively, due to firm adhesion between the cyst base and the muscularis propria, selective preservation of the adherent cyst base was performed to mitigate perforation and stenosis risks. Histopathology confirmed a GDC, with cyst lumen lined by gastric-type columnar epithelium and an outer smooth muscle layer. Focal ectopic pancreatic tissues were identified. The patient recovered without complications and remained asymptomatic during 6-month follow-up. Repeat gastroscopy showed the residual cyst wall conforming to antral mucosa, with no recurrence.
conclusionSubtotal resection of GDCs using ESD demonstrates a favorable prognosis.
