A systematic review and meta-analysis of the use of packing in the management of perianal abscesses.

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.
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
backgroundPerianal abscesses are common presentations and reasons for emergency general surgery admissions. Management involves incision and drainage of the abscess and packing the cavity with internal wound dressings. This meta-analysis aimed to assess in adults if packing an abscess or leaving it unpacked leads to a significant difference in the outcomes of pain on wound dressing, time to healing, rate of fistulation and abscess recurrence.
methodsRandomised controlled trials (RCTs) with participants aged 18 years or older that compared packing of perianal abscess cavities with no packing between 2002 and 2022 were searched for in December 2022 on OVID Medline and Embase, the CENTRAL register of trials, PubMed and Google Scholar. Risk of bias was assessed using the Cochrane Risk of Bias tool. Random effects meta-analysis was conducted on the data extracted.
resultsThree RCTs involving 490 patients were analysed for the outcomes of abscess recurrence and postoperative fistula formation; the data were not adequate to assess pain on dressing and time to healing. For unpacked versus packed, the pooled relative risk of abscess recurrence was 1.57 (95% confidence interval (CI) 0.764, 3.29,
conclusionsAnalysis of the outcomes suggests there is no significant difference with regards to rates of abscess recurrence or fistula formation between the packed and unpacked groups; however, appropriately powered RCTs are required in this area to provide more primary evidence to inform best practice and clinical management.
