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

backgroundThe safety of emergent laparoscopic repair of incarcerated ventral hernias is not well established. The objective of this study was to determine if emergent laparoscopic repair of incarcerated ventral hernias is comparable to open repair with respect to short-term clinical outcomes.

methodsPatients undergoing emergency repair of an incarcerated ventral hernia with associated obstruction and/or gangrene were identified using the ACS-NSQIP 2012-2016 dataset. One-to-one coarsened exact matching (CEM) was conducted between patients undergoing laparoscopic and open repair. Matched cohorts were compared with respect to morbidity, mortality, readmission, reoperation, missed enterotomies, and length of stay. Missed enterotomy was defined as any re-operative procedure within 30 days that required resection of large or small bowel segments, based on CPT codes. Multivariate analysis was conducted to determine adjusted predictors of morbidity.

resultsA total of 1642 patients were identified after CEM. Laparoscopic compared to open repair was associated with a lower rate of 30-day wound-morbidity (OR 0.35, 95% CI 0.22-0.57, p < 0.001). Laparoscopic repair was not associated with lower 30-day non-wound morbidity (OR 0.73, 95% CI 0.51-1.06, p = 0.094). Laparoscopic repair was associated with shorter LOS (3.6 days vs. 4.3 days, p = 0.014). A higher rate of missed enterotomies was observed in the laparoscopic cohort (0.7% vs. 0.0%, p = 0.031). There were no group differences with respect to 30-day readmission, reoperation, or mortality.

conclusionsEmergency laparoscopic repair of incarcerated ventral hernias is associated with lower rates of wound-morbidity and shorter hospital stays compared to open repair. However, laparoscopic repair is associated with a higher rate of missed enterotomies; a rate which is low and comparable to elective non-incarcerated ventral hernia repairs.
