Technical aspects of endoscopic internal drainage procedure, secured by endoscopic suture fixation: Experimental study.

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
Techniques of interventional endoscopy such as implantation of stents, leak closure by clips, or endoscopic suturing can help in reducing risk of an unfavorable outcome for patients with fistulas in the gastrointestinal tract. One method is endoscopic internal drainage (EID), which has been reported to have remarkable success. Because dislocation can reduce success, endoscopic suture techniques have been applied; however, devices could be cumbersome and/or expensive. The purpose of this experimental study was to evaluation the new endoscopic suturing needle-holder SutuArt for fixation of internal drains at a gastric fistula site. This suturing system is a through-the-scope needle-holder, which can be rotated within the working channel 360 degrees and maneuvered with the endoscope tip in many positions. The experiment was performed using an explanted porcine stomach with attached esophagus. Three consecutive running stitches were performed to provide sufficient fixation of the drain at an experimental "fistula" site. Afterward, the force was measured to dislocate the fixed drain. The results of 12 measurements (median duration 23 minutes; range: 19-44) at 6.7 Newton were compared with the reference value of 12 Newton (full-thickness open-stitch), thus withstanding a substantial pulling force. In conclusion, this study demonstrates the conceptual possibility of using an endoscopic needle holder for suture-fixation of a drain. Further clinical investigations are required to establish a full feasibility test of the concept.
