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

purposeOne-anastomosis-gastric-bypass (OAGB) has become a common bariatric procedure worldwide. Marginal ulcers (MU) are a significant non-immediate complication of gastric bypass surgeries. There seems to be concern among surgeons that MU are more common after OAGB compared with Roux-en-Y gastric bypass (RYGB) due to the constant and extensive exposure of the anastomosis to bile. The aim of this study was to compare the incidence, presentation, and management of MU between the two surgeries. MATERIALS AND

methodsA retrospective study of prospectively collected data was performed to include all consecutive patients between 2010 and 2020, who underwent elective OAGB or RYGB at our institution. Patients diagnosed with symptomatic MU were identified. Factors associated with this complication were assessed and compared between the two surgeries.

resultsSymptomatic MU were identified in 23/372 OAGB patients (6.2%) and 35/491 RYGB patients (7.1%) (p = 0.58). Time to ulcer diagnosis was shorter in OAGB patients (12 ± 11 vs. 22 ± 17 months, p < 0.01). Epigastric pain was the common symptom (78% OAGB vs. 88.5% RYGB, p = 0.7) and approximately 15% of ulcers presented with perforation upon admission (17% vs.11.4%, p = 0.7). Re-operation was required in 5/23 OAGB (21.7%) and 6/36 RYGB (17%) patients (p = 0.11) while the rest of the patients were managed non-operatively.

conclusionsThe risk of developing a marginal ulcer is similar between patients who underwent OAGB and RYGB. Patients diagnosed with MU following OAGB tend to present earlier; however, the clinical presentation is similar to RYGB patients. The management of this serious complication seems to be associated with acceptable outcomes with comparable operative and non-operative approaches.
