Innovative noninsufflation EFTR: sufficient endoscopic operative field by mechanical counter traction device.
Article in Surgical endoscopy, 2013. 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
backgroundNo reliable pure natural orifice transluminal endoscopic surgery (NOTES) mechanical counter traction (MCT) device for the flexible endoscope to obtain a sufficient surgical endoscopic field has yet been developed. Our experience with 10 cases of hybrid NOTES prompted the realization of the importance of an MCT device for the flexible endoscope and inspired us to establish innovative noninsufflation endoscopic full-thickness resection (EFTR) with an MCT device.
methodsWe performed 40 EFTR 40 mm in diameter on excised whole porcine stomachs. Twenty were resected by an MCT device to obtain a surgical field (MCT group), and another 20 were resected with a conventional endoscopic attachment (control group). We evaluated the successful resection rates of EFTR and procedure times between two groups. Next, we implemented EFTR with a custom prototype MCT device in three cases of stomach pseudotumors in female dogs. Gastric pseudotumors ~40 mm in diameter were marked within the open surgical field created by the MCT device. After resecting the pseudotumors, we conducted full-thickness suturing using over-the-scope clips.
resultsIn the MCT group, all 20 cases were completely resected. On the other hand, in the control group, only 8 cases were performed via EFTR (P < 0.01). The mean ± standard deviation EFTR procedure times for the MCT and control groups were 4.13 ± 0.824 and 36.26 ± 8.67 min, respectively (P = 0.001). In three dogs, sufficient surgical working spaces were obtained up to 78 mm (range, 65-78 mm), and full-thickness resections were performed safely and sutured with over-the-scope clips.
conclusionsOur new prototype MCT device effectively obtains a sufficient surgical endoscopic field during EFTR. We are developing a new MCT with a bending function to perform EFTR in any location in the stomach.
