Identification of technical errors and hazard zones in sleeve gastrectomy using OCHRA : "OCHRA for sleeve gastrectomy".
Observational study in Surgical endoscopy, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers, 3 of them syntheses that pooled it.
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
backgroundThe sleeve gastrectomy is an example of minimally invasive surgery. It is important to determine the critical steps of the procedure in order to reduce complications and increase safety and efficiency.
objectiveThe aim of this study was to detect the key elements of the sleeve gastrectomy and find the potential hazard zones of the procedure.
settingBariatric department of a large teaching hospital in the Netherlands.
methodsA prospective clinical observation study was performed including 60 sleeve gastrectomy procedures. An expert panel determined the key steps, and two experts assessed the procedures systematically for technical errors according to the principles of Observational Clinical Human Reliability Assessment (OCHRA).
resultsA total of 213 technical errors have been made, and the majority were made during mobilization of the greater curvature and during stapling of the stomach. In 44.6 %, errors had consequences and 96 additional actions were performed. There was a significant correlation between errors during opening of the lesser sac and postoperative complications, and between repositioning of the stapler and postoperative complications.
conclusionsIn this study, the 13 key steps of the SG were defined, and OCHRA was considered a valuable assessment tool for surgical performance and potential hazard zones. Most consequential errors are made during dissection of the greater curvature and during stapling of the stomach. Errors during the start of mobilization of the greater curvature and repositioning of the stapler lead to longer duration of the procedure and are associated with a higher risk of postoperative complications.
