30-Day Outcomes After Intraoperative Leak Testing for Bariatric Surgery Patients.
Observational study in The Journal of surgical research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundIntraoperative testing of anastomoses and staples lines is commonly performed to minimize the risk of postoperative leaks in bariatric surgery, but its impact is unclear. The aim of this study was to determine the association between leak testing and 30-d postoperative leak, bleed, reoperation, and readmission rates for patients undergoing laparoscopic sleeve gastrectomy (LSG) or Roux-en-Y gastric bypass (RYGB).
methodsThis is a retrospective observational study utilizing 2015-2016 data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database. Postoperative outcomes were compared using χ
resultsWe included 237,081 patients. Leak testing was performed on 73.0% and 92.1% of LSG and RYGB patients, respectively. LSG was associated with lower rates of leak, bleed, reoperation, and readmission than RYGB. On multivariable analysis, intraoperative leak testing was associated with increased rates of postoperative leak for LSG and RYGB (OR 1.48 and 1.90, respectively) and lower rates of bleed for LSG (OR 0.76). There were no significant associations between leak testing and rates of reoperation or readmission.
conclusionsUse of intraoperative leak testing was not associated with improved outcomes for either LSG or RYGB. A prospective trial investigating leak testing is warranted to better elucidate its impact.
