A Matched Cohort Comparison of Long-term Outcomes of Roux-en-Y Gastric Bypass (RYGB) Versus Single-Anastomosis Duodeno-ileostomy with Sleeve Gastrectomy (SADI-S).

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 long-term effectiveness of Roux-en-Y gastric bypass (RYGB) and single-anastomosis duodeno-ileostomy with sleeve gastrectomy (SADI-S) is unknown. PURPOSE: Compare the long-term outcomes.
settingSingle private institute, USA. MATERIALS AND
methodsData from 1254 patients who underwent primary RYGB or SADI-S were used for a retrospective matched cohort. Data were obtained by matching every RYGB patient to a SADI-S patient of the same sex, body mass index (BMI), and weight. Only patients out 5 years and had at least one > 5-year follow-up visit were included.
resultsThe matched cohort included 61 RYGB and 61 SADI-S patients. There was no statistical, demographic difference between the two groups. At 5 years, a 100% follow-up was available in each group. The intraoperative outcomes were significantly better with SADI-S. The 30-day readmission, reoperation, emergency department (ED) visits, and complication rates were statistically similar between the two groups. The long-term complication rates, Clavien-Dindo grade IIIb complications, and number of patients with more than one complication were significantly lower with SADI-S. Weight loss was significantly greater in the SADI-S group at 5 years. The long-term weight-loss failure rate was significantly higher in the RYGB group. The SADI-S procedure was associated with fewer reintervention through 6 years (14.7% patients vs. 39.3% patients, p = 0.001). Conversion or reversal of the procedure was required only in the RYGB group. There also was no significant difference in nutritional outcomes between the two procedures.
conclusionsThis study showed that problems, including long-term complications, reinterventions, weight-loss failure, and conversion, were more often associated with RYGB than with SADI-S. The SADI-S may be considered one of the viable alternatives to RYGB.
