All-in-one sphincterotome with high rotation performance and freely bendable blade for endoscopic sphincterotomy in patients with surgically altered anatomy (a case series with video).
Article in DEN open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
A new type of sphincterotome released to the market recently has high rotation performance and a freely bendable blade. It is devised to be singly capable of accommodating not only normal anatomy but also cases with surgically altered anatomy. This study was undertaken for clinical evaluation of the usefulness of this new sphincterotome. Eight cases in a reconstructed intestine for which cannulation or endoscopic sphincterotomy (EST) had been performed were extracted from 32 cases for which endoscopic retrograde cholangiopancreatography-related procedures were performed using the sphincterotome developed during November 2023 through February 2024. The cases were investigated retrospectively. Among these, EST was applied to six cases. Cannulation was performed using the developed sphincterotome in the native papilla in four cases. The primary endpoints were the success rate of cannulation in surgically altered anatomy and the success rate of EST. Secondary endpoints were complications and usability for operators. Usability for operators was evaluated by questionnaire for several items on a 5-point scale. EST was conducted successfully in all six cases subjected to EST. Mild hemorrhage was observed in one case (17%) as an adverse event after EST. Deep cannulation to the native papilla with the developed sphincterotome was conducted successfully in three cases (75.0%). Evaluation results by operators were 4.4 ± 0.55 for rotation performance, 4.00 ± 0.63 for incision performance, 4.29 ± 0.49 for deep cannulation performance, and 4.07 ± 0.19 for overall evaluation. In conclusion, this developed sphincterotome might be very useful for EST and cannulation in cases with surgically altered anatomy.
