Outcomes of Zenker's peroral endoscopic myotomy (Z-POEM) for treatment of Zenker's diverticulum at our tertiary care center: a single-institution retrospective cohort study.

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
backgroundTreatment of Zenker's diverticulum (ZD) has been revolutionized with the introduction of endoscopic techniques. Z-POEM has been shown to have excellent safety and efficacy. We report our experience with the Z-POEM for the treatment of ZD.
methodsThis is a single-institution retrospective study from 2020 to 2024. The primary outcome was clinical success, defined as improvement in dysphagia score to ≤ 1 without need for a reintervention the first 6 months. Secondary outcomes included technical success, rate of reintervention, and post-procedural complications.
resultsA total of 32 patients (male 62.5%, mean age 74.2 ± 10.7 years) underwent Z-POEM for treatment of Zenker's diverticulum. The mean diverticulum size was 26.7 ± 9.9 mm. The American Society of Anesthesiologists (ASA) grade was 3 in 56.3% of patients; the rest of the patients were ASA grade 2. Technical success was achieved in 100% of patients (n = 32) and clinical success was achieved in 96.9% of patients (n = 31). The mean procedure time was 48.6 ± 19.1 min. More than two thirds of the patients (68.8%) were discharged home the same day. One patient developed atrial fibrillation postprocedurally. Mean dysphagia scores improved from 1.5 ± 0.8 before the procedure to 0.09 ± 0.3 after the procedure at most recent follow-up (p < 0.001). Mean regurgitation scores improved from 2.3 ± 1.2 before the procedure to 0.13 ± 0.3 after the procedure at most recent follow-up (p < 0.001). Reintervention due to recurrence of symptoms was required in six patients (18.8%) during a mean length of follow-up of 10.8 months (range 1 to 43 months). Most of the reinterventions (80%) were required after 17 months from the initial Z-POEM.
conclusionsZ-POEM is a safe, effective, and durable treatment for Zenker's diverticulum, but reoperation is needed in 1 out of 5 patients in the short term.
