Stapler-Less Robotic Partial Gastrectomy: a Safety and Feasibility Experimental Study.
Article in Obesity surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 true preliminary work has been performed and published on the use of the bipolar cautery devices for transection of the stomach when performed as a part of the sleeve gastrectomy or gastric wedge resection. The objective of this study was to investigate the feasibility and safety of substitution of linear surgical stapling devices for use of a bipolar electrosurgical sealing instrument in the performance of a totally robotic partial gastrectomy (TRPG).
methodsTen female pigs were assigned to an intervention or control group. Intervention included TRPG with a robotic bipolar tissue coagulation device. In the control group, TRPG was performed using the staplers. Assessed outcomes included presence of the intraoperative and postoperative bleeding or leak and features of the sections from the stapled line or sutured line.
resultsMean operating time was (130 ± 31 min) and (87 ± 23 min) in the study and control groups (p = 0.03). Intraoperative gastroscopy revealed slow bleeding associated with the staple line in 3/5 control pigs; oozing was not appreciated in any of the study pigs (0/5). No leak was detected during intraoperative gastroscopy. No major complications were suspected postoperatively or identified at postmortem exam in either group. Mean injury width was (1.12 ± 0.93 mm) in the control group with greater mean injury width (7.88 ± 3.73 mm) in the study group (p = 0.001). Mean depth of ulceration was (0.99 ± 0.94 mm) in the control group, with greater mean ulceration depth (2.25 ± 0.84 mm) in the study group (p = 0.002).
conclusionThe study showed the technical feasibility of performing stapler-less gastric wedge resection. The electrocautery alone failed to demonstrate the technical feasibility which was obtained with the concomitant use of a tissue clamp and a suture.
