Association between intraoperative irrigation volume and postoperative abdominal abscess in perforated peptic ulcer.

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
backgroundPerforated peptic ulcer is a critical emergency disease requiring surgery, and postoperative intra-abdominal abscess (IAA), an organ/space surgical site infection (SSI), is a common complication. Intraoperative irrigation is a common IAA prevention approach; however, scientific evidence supporting its effectiveness is lacking. We aimed to investigate the association between intraoperative irrigation volume and IAA using multicentre data.
methodsThis multicentre retrospective cohort study was conducted between January 2011 and December 2023. The study included patients aged ≥ 18 years who underwent laparotomy or laparoscopy for perforated peptic ulcer, defined as perforation of a gastric or duodenal ulcer. The primary and secondary outcomes were IAA incidence and superficial incisional SSI, respectively, and their association with the intraoperative irrigation volume was determined through multivariable logistic regression analyses.
resultsThe study included 478 patients with a median age of 66 years (interquartile range [IQR]: 54-75 years), 344 (72.0%) of whom were males. The median irrigation volume was 7.0 (IQR: 5-10) L. Among the 478 patients, IAA and superficial incisional SSI occurred in 52 (10.9%) and 71 (14.9%), respectively. The irrigation volume and the outcomes exhibited no significant association (for IAA: adjusted odds ratio [AOR] = 1.04, 95% confidence interval [CI] = 0.97-1.11, p = 0.25; for superficial incisional SSI: AOR = 1.07, 95% CI = 1.00-1.14, p = 0.053).
conclusionsThere was no statistically significant association between increased intraoperative irrigation volume and a decreased incidence of postoperative IAA formation. These findings suggest that alternative strategies, rather than uncontrolled high-volume irrigation, are required for IAA prevention.
