Efficacy of lidocaine injection method for esophageal endoscopic submucosal dissection: single-center, double-blind, randomized controlled trial.
Trial report in Surgical endoscopy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundIntraoperative body movements are one of the causes of difficulty in performing esophageal endoscopic submucosal dissection (ESD) under conscious sedation. The use of local anesthetics as local injection materials during ESD may overcome this difficulty. We clinically evaluated the lidocaine injection method (LIM) in the submucosa during esophageal ESD.
methodsThis was a single-center, prospective, double-blind, randomized trial. Patients who underwent esophageal ESD under conscious sedation from June 2018 to May 2021 were included in this study. In the LIM group, lidocaine was used for submucosal injection during ESD; in the control group, ESD was performed without lidocaine. The primary outcome was the presence of body movements.
resultsFifty patients were enrolled and randomized in a 1:1 ratio in two groups. The incidence of body movements was significantly lower in the LIM group (12% [3/25]) than in the control group (48% [12/25]; P = 0.01). The median additional dose of midazolam was 2 mg (interquartile range [IQR]: 0.5-4 mg) in the LIM group and 4 mg (IQR: 3-6 mg) in the control group, which was significantly lower in the LIM group (P < 0.01). The median visual analog scale score for endoscopist satisfaction was 7 (IQR: 5-8) in the LIM group and 5 (IQR: 4-6.5) in the control group, which was significantly higher in the LIM group.
conclusionsLIM during esophageal ESD reduced body movements while decreasing the level of sedation. Therefore, LIM during esophageal ESD is an option for maintaining good sedation (UMIN000032804).
