Early experience with use of an endoscopic "hot" scissor-type knife for myotomy during per-oral endoscopic myotomy procedure.

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
aimsCurrent devices used for per-oral endoscopic myotomy (POEM) function predominantly to either cut tissue or coagulate vessels. When bleeding vessels are encountered within the submucosa or muscle, dedicated coagulation grasping devices are often necessary. An endoscopic "hot" scissor-type knife is available that combines coagulation and cutting functions. Scissor-type knives may therefore be helpful during the POEM procedure.
methodsWe report 4 cases of achalasia that were treated by the POEM procedure using the Stag Beetle scissor-type knife for myotomy. Patients were identified from a prospectively maintained database of patients undergoing POEM at our center between September and October 2017. A single operator (K.J.C.) performed all of the procedures using both a hybrid knife and an SB knife. Demographic and clinical data were collected for all patients.
resultsAll 4 POEM procedures were performed successfully without any adverse events. Only 3 spontaneous bleeding episodes occurred among the 4 procedures, and no perforation occurred. The patients were all doing very well at clinic follow-up at 4 weeks.
conclusionsThe technique of using the SB knife during myotomy during the POEM procedure is feasible and appears safe. Muscle tissue and blood vessels can be coagulated and cut simultaneously, reducing bleeding and improving control. Further comparative studies are warranted to evaluate the efficacy, safety, and cost effectiveness against existing techniques.
