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

purposeGuidelines recommend that the reoperation of a recurrent inguinal hernia should be by the opposite approach (anterior-posterior) than the primary repair. However, the level of evidence supporting the guidelines is partially low. The purpose of this study was to compare re-reoperation rates between repairs performed according to the guidelines with the ones performed against it.

methodsThis cohort study was based on the Danish Hernia Database, including 4344 patients with two inguinal hernia repairs in the same groin. Four groups were compared as follows: Lichtenstein-Lichtenstein vs. Lichtenstein-Laparoscopy, and Laparoscopy-Laparoscopy vs. Laparoscopy-Lichtenstein. The outcome was re-reoperation rates, which were compared by crude rates, cumulated rates, and hazard ratios.

resultsThere was no difference in the re-reoperation rates when the primary repair was laparoscopic, regardless of the type of reoperation. However, Lichtenstein-Lichtenstein had a significantly higher re-reoperation rate compared with Lichtenstein-Laparoscopy (crude rate 8.7 vs. 3.1 %, p value <0.0005; Hazard Ratio 2.46, 95 % CI 1.76-3.43). Further analysis showed that the higher risk of re-reoperation for Lichtenstein-Lichtenstein was only seen if the primary hernia was medial.

conclusionsA primary Lichtenstein repair of a primary medial hernia should be reoperated with a laparoscopic repair. A primary Lichtenstein repair of a primary lateral hernia can be reoperated with either a Lichtenstein or a laparoscopic repair according to surgeon's choice. For a primary laparoscopic operation, the method of repair of a recurrent hernia did not affect the re-reoperation rate.
