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

objectiveTo evaluate the safety and efficacy of revisional Roux-en-Y gastric bypass (RYGB) after adjustable gastric banding (AGB) or sleeve gastrectomy (SG) compared with primary RYGB, in regard to early and late morbidity, weight, and resolution of obesity-related comorbidities.

methodsThe group of patients undergoing revisional RYGB was matched in a 1:1 ratio with control patient who underwent a primary RYGB, based on age, gender, American Society of Anesthesiologist (ASA) score, preoperative body mass index (BMI), and diabetes mellitus. Demographics, anthropometrics, preoperative work-up, and perioperative data were retrieved.

resultsOne hundred fifteen patients (16 males and 99 females) with a mean age of 45.5 ± 1.5 years underwent revisional RYGB following either LAGB in 82 patients (71.3%) or laparoscopic sleeve gastrectomy (LSG) in 33 patients (28.7%). There was no conversion and no mortality in either group. Revisional RYGB was associated with similar early (16.5 vs 15.6%, ns) and late (42.6% vs 32.2%, ns) morbidity rates with a mean follow-up of 25.3 ± 16.6 months compared to primary laparoscopic Roux-en-Y gastric bypass. The revisional RYGB group had significantly less weight loss (mean %EWL 67.4 ± 20.7 vs 72.7 ± 22.9, p = 0.023 and mean %EBMI 68.1 ± 22 vs 78.3 ± 25.7, p = 0.01) at the time of 1 year. Improvement of comorbidities including hypertension (62.5 vs 70.5%; p > 0.05), diabetes (73.7 vs 79%; p > 0.05), and obstructive sleep apnea syndrome (100 vs 97%; p > 0.05) was similar.

conclusionThis large case-matched study suggests that conversion of SG or AGB to RYGB is feasible with early and late comparable morbidity in an accredited center; even weight results might be inferior.
