Dual-function robotic gripper for traction and closure in gastric endoscopic submucosal dissection: an in vivo porcine model study (with video).
Article in Surgical endoscopy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivesEndoscopic submucosal dissection (ESD) is a technically complex procedure associated with prolonged operative duration and a heightened risk of complications. To enhance procedural efficiency and safety, various adjunctive techniques have been introduced, particularly for tissue traction and mucosal defect closure. This study aimed to assess the feasibility and efficacy of a novel robotic dual-function gripper capable of performing both tissue traction and defect approximation in an in vivo model.
methodsA dual-function robotic gripper was developed to facilitate submucosal dissection and post-ESD closure. Comparative experiments were conducted using robot-assisted ESD (RESD) and conventional ESD (CESD) on 24 gastric lesions created in six live pigs. In the RESD group, mucosal defects were closed using the robotic gripper in combination with through-the-scope (TTS) clips, whereas closure in the CESD group was performed using standard TTS clips alone. Primary outcomes included total procedure time, dissection speed, blind dissection rate, and success rate of defect closure. Endoscopic and histological evaluations were conducted on postoperative day 14.
resultsAll lesions were resected without adverse events. Specimen sizes were comparable between groups (928.1 ± 74.5 mm
conclusionThe robotic dual-function gripper significantly enhanced technical performance and mucosal healing in gastric ESD within a porcine model, suggesting its potential as an effective adjunct for gastric therapeutic endoscopy.
