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

introductionParastomal hernias are frequent and highly recurrent. The sandwich technique is a combination of the keyhole and Sugarbaker techniques, using a double intraperitoneal mesh. The objective of this study was to assess the outcomes of the sandwich technique, specifically focusing on recurrence rates. MATERIALS AND

methodsObservational retrospective study conducted in two tertiary referral centers in Catalonia, Spain. All consecutive patients who underwent parastomal hernia repair using the sandwich technique between 1st January 2016 and 31st December 2021 were included.

resultsA total of 38 patients underwent the laparoscopic sandwich technique for parastomal hernia repair. The overall recurrence rate was 7.9% (3/38), with a median follow-up of 39 months (IQR: 12.3-56.5). According to the EHS classification for parastomal hernia, there were 47.4% (18/38) type I defects, 10.5% (4/38) type II defects, 28.9% (11/38) type III defects, and 13.2% (5/38) type IV defects. The used mesh was predominantly TiMesh® (76.3%; 29/38), followed by DynaMesh® IPOM (23.7%; 9/38). Patients with recurrence exhibited higher rates of seroma, hematoma, surgical site infection, and one case of early recurrence attributed to mesh retraction. Consequently, postoperative complications emerged as the primary risk factor for hernia recurrence.

conclusionThe sandwich technique demonstrated recurrence rates consistent with those reported in the existing literature.
