Zenker's peroral endoscopic myotomy for treating zenker's diverticulum in an elderly patient: a case report and literature review.
Article in Frontiers in surgery, 2026. 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: Zenker's diverticulum (ZD) is a rare esophageal disorder, and traditional surgical interventions are associated with significant trauma and poor tolerance in elderly patients. Case summary: An 85-year-old female presented with a one-year history of progressive dysphagia, accompanied by regurgitation, coughing, and a 5 kg weight loss. Diagnostic evaluations, including barium esophagography, chest computed tomography (CT), and endoscopy, confirmed an upper esophageal ZD (3 cm in diameter). Treatment: The patient underwent submucosal tunneling endoscopic septum division (STESD), which is widely standardized in current literature as Zenker's peroral endoscopic myotomy (Z-POEM). Key procedural steps included mucosal incision, submucosal tunneling, complete septum myotomy, and mucosal closure using titanium clips. Postoperative recovery was uneventful, with no complications such as bleeding or perforation. Conclusion: Z-POEM demonstrates minimally invasive advantages, safety, and efficacy in treating ZD, particularly for elderly patients with high surgical risks. This technique represents a promising therapeutic option in this population.
