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

backgroundVentral hernias are a common finding during bariatric surgery; however, the risks and benefits of repair during surgery remain unclear. Using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database, we examined the short-term outcomes of patients undergoing bariatric surgery with concurrent ventral hernia repair (VHR) versus bariatric surgery alone.

methodsPatients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) were included. A propensity-matched analysis was performed between laparoscopic bariatric surgery with and without concurrent VHR. The primary outcome was the 30-day major complication rate which includes but is not limited to 30-day reoperation, deep surgical site infection, and sepsis. Secondary outcomes included operative time, length of hospital stay, 30-day readmission, and 30-day mortality.

resultsA total of 430,225 patients were included, of which 4690 (1.1%) received concomitant VHR. With one-to-one propensity score matching, 4648 pairs were selected. Concurrent VHR was associated with a higher major complication rate (5.8 vs 3.8%, p < 0.001) but no significant difference in mortality (0.3 vs 0.2%, p = 0.531). Both LSG with VHR (3.2 vs 2.4%, p = 0.007) and RYGB with VHR (9.3 vs 5.7%, p < 0.001) were associated with an increase in major complications.

conclusionsPatients undergoing VHR during bariatric surgery do not experience higher mortality. However, these patients have an elevated risk of major complications with this risk being higher among patients undergoing VHR and LRYGB. Bariatric surgeons should consider these risks when choosing to perform VHR at the time of bariatric surgery.
