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

backgroundParastomal hernia repair is a complex surgical procedure with high recurrence and complication rates. This retrospective nationwide cohort study presents the results of different parastomal hernia repair techniques in Finland.

methodsAll patients who underwent a primary end ostomy parastomal hernia repair in the nine participating hospitals during 2007-2017 were included in the study. The primary outcome measure was recurrence rate. Secondary outcomes were complications and re-operation rate.

resultsIn total, 235 primary elective parastomal hernia repairs were performed in five university hospitals and four central hospitals in Finland during 2007-2017. The major techniques used were the Sugarbaker (38.8%), keyhole (16.3%), and sandwich techniques (15.4%). In addition, a specific intra-abdominal keyhole technique with a funnel-shaped mesh was utilized in 8.3% of the techniques; other parastomal hernia repair techniques were used in 21.3% of the cases. The median follow-up time was 39.0 months (0-146, SD 35.3). The recurrence rates after the keyhole, Sugarbaker, sandwich, specific funnel-shaped mesh, and other techniques were 35.9%, 21.5%, 13.5%, 15%, and 35.3%, respectively. The overall re-operation rate was 20.4%, while complications occurred in 26.3% of patients.

conclusionThe recurrence rate after parastomal hernia repair is unacceptable in this nationwide cohort study. As PSH repair volumes are low, further multinational, randomized controlled trials and hernia registry data are needed to improve the results.
