Efficacy and safety of esophageal submucosal tumors treated with internal traction method-assisted submucosal tunneling endoscopic resection: a single-center, single-blind, randomized controlled study.
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
BACKGROUND AND
objectivesSubmucosal tunnel endoscopic resection (STER) is an effective technique for treating esophageal submucosal tumors, but the efficacy and safety of treating esophageal submucosal tumors with internal traction method-assisted STER have not been determined. The objectives of this study were to assess the feasibility, safety, and efficacy of internal traction method-assisted STER for the removal of esophageal submucosal tumors. PATIENTS AND
methodsEighty patients who underwent STER for esophageal submucosal tumors were included in the study. They were randomized and assigned to the two groups. The dual-knife method was used for STER. Forty patients underwent conventional STER (control group) and 40 underwent internal traction method-assisted STER in which self-made rubber band traction with clips was used (study group). In the study group, one end of the self-made rubber band was fixed on the surface of esophageal submucosal tumors with a clip, and the other end of the self-made rubber band was set on the anal side of the contralateral esophageal wall with a clip.
resultsSTER was successful in all cases. Lesion features and demographics were similar between the two groups. In addition, broad exposure of the submucosal tissue was obtained by applying tension to the self-made rubber band traction with clips. The en bloc resection rate and complete resection rate were both 100% in the study group. However, the en bloc resection rate and complete resection rate were 85.0% and 100%, respectively, in the control group. Complications, such as perforation and pneumomediastinum, were significantly reduced in the study group, and there was a significant difference in the number of occurrences of bleeding, operation duration, fasting time, and patient length of stay between the study group and control group (P < 0.05). During the mean 13.7 month follow-up, there were no patients with esophageal fistula, recurrence, or distant metastasis in either group.
conclusionsThis original study showed that esophageal submucosal tumors could be effectively and safely treated with internal traction method-assisted STER, and this technique might be superior to conventional STER due to its fewer complications, shorter operation duration, and shorter inpatient length of stay.
