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

purposeRecurrence is a known complication to inguinal herniotomy with an incidence of 10 to 15 percent (Hernia Surge Group in Hernia 22:165, 2018). Previous studies have shown that direct hernia or large defects are risk factors for postoperative seroma formation (Morito et al. in Surg Endosc https://doi.org/10.1007/s00464-021-08814-2 , 2021). These types of defects are often closed during open herniotomy (Rosenberg et al. in Dan Med Bull 58: C4243, 2011). This is not routine during laparoscopic surgery. A recent study has indicated that closure of the medial defect during laparoscopy may reduce recurrence and seroma formation. As a result, we performed the present systematic review to evaluate the efficacy of this add on to the standard procedure.

methodsAn extensive search was carried out in PubMed and Embase. All studies involving adults undergoing laparoscopic direct hernioplasty were enrolled and screened with predefined inclusion criteria, to be part of a systematic review with data synthesis and meta-analysis.

resultsThe search identified 108 publications of which four met the inclusion criteria. Two studies (Ng et al. in Hernia 24:1093-1098, 2020; Usmani et al. in Hernia 24:167-171, 2020) showed reduced risk of recurrence. The remaining studies (Zhu et al. in Surg Laparosc Endosc Percutan Tech 29:18-21, 2019; Li and Zhang in Surg Endosc 32:1082-1086, 2018) reported no recurrence in any of the patients included. Two articles (Usmani et al. in Hernia 24:167-171, 2020; Zhu et al. in Surg Laparosc Endosc Percutan Tech 29:18-21, 2019) showed a decrease in risk of postoperative seroma, one showed a significant increase (Ng et al. in Hernia 24:1093-1098, 2020). None of the included studies showed an increase in the risk of postoperative pain or postoperative complications.

conclusionThis review suggests that closure versus non-closure of the medial hernia defect in laparoscopic inguinal hernioplasty reduces the risk of recurrence and seroma formation without an increase in postoperative pain or complications. Further randomized controlled trials are needed for further evaluation.
