Conversions of Roux-en-Y gastric bypass to duodenal switch (SADI-S and BPD-DS) for weight regain.

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
backgroundDuodenal switch is a choice of conversion when patients fail to lose or regain weight after Roux-en-Y gastric bypass (RYGB). This study aims to evaluate the effectiveness and safety of duodenal switch as a secondary operation for patients who presented with insufficient weight loss or weight regain after a RYGB.
methodsA retrospective chart review was performed on 15 patients who underwent a conversion of RYGB to single anastomosis duodeno-ileal bypass with sleeve (SADI-S) or biliopancreatic diversion with duodenal switch (BPD-DS) due to weight regain between December 31, 2013 and October 31, 2018. For the body mass index (BMI) analysis, the multilevel model for change was used.
resultsOf 15 patients, 10 underwent a conversion to SADI-S, and 5 underwent a conversion to BPD-DS. Also, 7 patients underwent the conversion in two-stages, while 8 did as single-stage. One patient had a duodenal stump leak after SADI-S, and another patient had a sleeve leak after BPD-DS. One patient underwent a reoperation to increase the common channel 20 months after the conversion to BPD-DS due to malnutrition. There was no mortality. Mean percentage of total weight loss (TWL) was 18.4% at 6 months, 25.0% at 12 months, 26.4% at 18 months, and 25.7% at 24 months after the conversion. The rate of decrease in BMI was slower in SADI-S patients than in BPD-DS patients (p < 0.01), adjusting for preoperative BMI.
conclusionConversions of RYGB to SADI-S and BPD-DS can provide significant additional weight loss. However, complications and malnutrition can develop after the conversion, and further research is needed for evaluating safety.
