1 · What the graph read from 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.

2 · The registry

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

backgroundBariatric surgery outcomes have been examined in Germany since January 1, 2005. All data were registered prospectively in cooperation with the Institute of Quality Assurance in Surgery at the Otto-von-Guericke University Magdeburg.

methodsThe data were collected from an online data bank. Data collection began in 2005 for gastric banding (GB) and Roux-en-Y gastric bypass (RYGB) results. In addition to primary bariatric operations, data regarding the complications of revision procedures and redo operations were analyzed. Participation in the quality assurance study was required for all certified centers in Germany.

resultsRYGBs are a popular redo operation after failed gastric banding. In the German Bariatric Surgery Registry (GBSR), we analyzed data from 263 RYGB operations that used a one-step approach after GB and 116 operations that used a two-step approach. The leakage rates for primary RYGB decreased to 1.8%. The incidence of leakage after a one-step RYGB after GB was lower (1.9%) than after the two-step procedure (2.6%).

conclusionRYGBs are popular procedures after failed GB in Germany. The multivariable analysis for overall intraoperative complications revealed a significant difference between the two-step and the one-step procedure. In an unadjusted and multivariate assessment, the one-step procedure had statistically lower general postoperative complications than the two-step approach. Therefore, we suggest performing band removal and RYGB as a one-step procedure. Further analysis is necessary to evaluate the risk factors for the one-step procedure. Follow-up investigations must be performed to determine whether RYGB is an effective and safe option after GB.
