Novel triangle tip-jet knife increases efficiency in peroral endoscopic myotomy for achalasia.

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
aimPeroral endoscopic myotomy (POEM) is performed globally for the treatment of achalasia. A newly available endoscopic knife, the triangle tip-jet (TTJ) (Olympus Triangle TipKnife-J, KD-645L), has the capability of knife dissection along with submucosal injection. We aim to present our experience with the TTJ knife in comparison to the conventional TT knife in POEM, with a focus on procedural characteristics including time, efficiency, and the number of instrument exchanges.
methodsAll patients with achalasia who underwent POEM between March 2016 and March 2020 at a single tertiary academic center were included in the retrospective cohort. Demographic, procedural, and outcomes data were compared.
resultsNinety-two procedures, 48 using the TT knife, and 44 with the TTJ knife were analyzed. Demographic data were similar. Procedure time was reduced using the TTJ knife (87
conclusionsThe use of the TTJ knife increases efficiency during POEM for Achalasia. The total procedure time is decreased by 28-41%, and procedural efficiency is increased by 22-34%.
