Conversion of Sleeve Gastrectomy to Roux-en-Y Gastric Bypass: Indications, Prevalence, and Safety.

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
backgroundSleeve gastrectomy (SG) frequently requires conversion to Roux-en-Y gastric bypass (RYGB) due to gastroesophageal reflux disease (GERD) or weight recurrence. Current evidence evaluating the safety of conversion from SG to RYGB and its indications is limited to single centers.
methodsThe objective was to determine the rate of serious complications and mortality of conversion of SG to RYGB (SG-RYGB) compared to primary RYGB (P-RYGB). This was a retrospective analysis of the MBSAQIP database which includes 30-day outcomes. Individuals undergoing P-RYGB or SG-RYGB were included. Multivariable logistic regression was performed to determine if revisional surgery was an independent predictor of serious complications or mortality.
resultsIn 2020 and 2021, 84,543 (86.3%) patients underwent P-RYGB and 13,432 (13.7%) underwent SG-RYGB. SG-RYGB cohort had lower body mass index, lower rates of diabetes and hypertension, and higher rates of GERD. GERD was the most common indication for revision (55.3%) followed by weight regain (24.4%) and inadequate weight loss (12.7%). SG-RYGB had longer operative times (145 vs. 125 min, p < 0.001) and a higher rate of serious complications (7.2 vs. 5.0%, p < 0.001). This included higher rates of anastomotic leak (0.5 vs. 0.4%, p = 0.002), bleeding (2.0 vs. 1.6%, p < 0.001), and reoperation (3.0 vs. 1.9%, p < 0.001) but not death (0.1 vs. 0.1%, p = 0.385). On multivariable analysis, SG-RYGB was independently predictive of serious complications (OR 1.21, 95%CI 1.12 to 1.32, p < 0.001) but not mortality (p = 0.316).
conclusionsWhile SG-RYGB is safe with a low complication rate, SG-RYGB was associated with a higher rate of serious complications compared to P-RYGB.
