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

The reported incidence of trocar site hernias in bariatric surgery ranges between 0.5 and 3%. The best available evidence derives from retrospective studies analysing prospective databases, thus including only patients who presented with symptoms or received surgical treatment due to trocar site hernias after a laparoscopic bariatric procedure. A systematic literature research was conducted up until September 2017. Search strategies included proper combinations of the MeSH terms 'laparoscopy' and 'bariatric surgery', 'trocar/port' and 'hernia'. Searches were not limited by publication type or language. The review was registered in PROSPERO (ID 85102) and performed according to the PRISMA guidelines. Sixty-eight publications were included. Pooled hernia incidence was 3.22 (range 0-39.3%). Thirteen trials reported systematic closure of the fascia; 12 trials reported no closure. Data availability did not allow for pooling to calculate relative risk. Higher BMI and specific hernia examination using imaging modalities were associated with a significantly higher incidence of trocar site hernias. Studies dedicated to detection of TsH reported a pooled incidence of 24.5%. Trocar site hernias are an underestimated complication of minimally invasive multiportal bariatric surgery. While high-quality trials are not available allowing for a precise calculation of the incidence, existing data are indicative of very high incidence rates. Risk factors for developing a trocar site hernia in bariatric surgery have not yet been systematically analysed. Prospective studies in this field are necessary.
