Proximal Leakage After Laparoscopic Sleeve Gastrectomy: an Analysis of Preoperative and Operative Predictors on 1738 Consecutive Procedures.

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 purpose of this paper was to search for predictive factors for proximal leakage after laparoscopic sleeve gastrectomy (LSG) in a large cohort from a single referral center. MATERIALS AND
methodsOne thousand seven hundred and thirty-eight patients, collected in a prospectively held database from 2008 to 2016, were retrospectively analyzed. The correlation between postoperative leakage and both preoperative (age, gender, height, weight, BMI, and obesity-related morbidities) and operative variables (the distance from pylorus at which the gastric section was started, operative time, experience of surgeons who performed the LSG, and the surgical materials used) was analyzed. The experience of the surgeons was calculated in the number of LSGs performed. The surgical materials considered were stapler, cartridges, and reinforcement of the suture.
resultsProximal leakage was observed in 45 patients out of 1738 (2.6%). No correlation was found between leakage and the preoperative variables analyzed. The operative variables that were found to be associated with lower incidence of leakage at the multivariate analysis (p < 0.05) were the reinforcement of the staple line (or overriding suture or buttressing materials) and the experience of the surgeons. A distance of less than 2 cm from the pylorus resulted to be significantly related to a higher incidence of fistula at the univariate analysis.
conclusionsIn this large consecutive cohort study of LSG, proximal staple line reinforcement (buttress material or suture) reduced the risk of a leak. The risk of a proximal leak was much higher in the surgeons first 100 cases, which has implications for training and supervision during this "learning curve" period.
