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

backgroundSeroma formation is a prevalent postoperative complication following laparoscopic inguinal hernia repair. While seromas are mostly self-absorbed, they can cause discomfort for the patient and complicate the assessment of hernia recurrence. Two primary techniques for managing the hernia sac are sac transection and complete sac reduction. This article aims to evaluate whether sac transection leads to a higher incidence of seroma compared to sac reduction and to review the main preventive strategies for seroma.

methodsFour databases (PubMed, MEDLINE, Embase and Cochrane Library) and ClinicalTrials.gov were comprehensively searched for relevant studies. The date of the last search was 25 March 2024. The results reported should include reliable information on seroma incidence, mean operation time, hospital stay and postoperative complications.

resultsThe present study included 6 studies compared the results of indirect hernia sac transection and complete sac reduction. The pooled results indicated that indirect hernia sac transection was associated increased seroma formation (OR = 1.74, 95% CI: 1.35-2.24%), and there was no statistical difference in mean operation time, hospital stay and recurrence between the sac transection (TS) and sac reduction (RS) groups. Postoperative pain was evaluated in 4 studies. There was no statistical difference between the two groups in postoperative pain reported in each of the four articles.

conclusionsThe study revealed that transection of the indirect hernia sac is associated with a higher incidence of seroma, but does not increase the occurrence of other complications.
