Cap-assisted 5-cm diameter cold snare treatment for phytobezoars: A retrospective study.
Article in PloS one, 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
BACKGROUND AND
aimsThe current treatment options for phytobezoars include endoscopic therapy, chemical lysis, and surgical treatment. These methods are often less efficient or are associated with more adverse events in large-diameter phytobezoars. This study aimed to evaluate the feasibility, effectiveness, and safety of the cap-assisted 5-cm diameter cold snare technique for the treatment of huge phytobezoars.
methodsThis retrospective study enrolled 24 patients with huge phytobezoars treated with the cap-assisted 5-cm diameter cold snare technique in the Department of Gastroenterology, Nanchong Central Hospital, between December 25, 2022, and October 1, 2023. Patients' clinical characteristics and bezoar features were evaluated, the procedure was recorded, and patients were reviewed and followed with gastroscopy 1 day and 1 month after the procedure.
resultsTwenty-four patients with huge phytobezoars were treated with the cap-assisted 5-cm diameter cold snare technique during the study period. The median phytobezoar size, break-up time, and extraction time were 5 × 3 cm (range 4-10, 3-5), 10.08 minutes (range 3.31-31.48), and 9.63 minutes (range 6.5-35.71), respectively. All patients achieved satisfactory treatment results, with no residual phytobezoars or gastrointestinal injuries on gastroscopy review 1 day after the procedure, and no postoperative adverse events were found on gastroscopy follow-up 1 month after the procedure.
conclusionsThe results of this study indicated that the cap-assisted 5-cm diameter cold snare technique is safe, feasible, and effective for treating huge gastric bezoars, offering a new treatment method for this disease. Given the limitations inherent in the retrospective nature and relatively small sample size of this study, a prospective, multicenter, large-sample clinical trial is warranted to evaluate the efficacy and generalizability of this technique comprehensively.
