Are Drains After Trauma Splenectomy Associated with Organ Space Surgical Site Infections?
Article in Surgical infections, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionLeft upper quadrant (LUQ) drain use after trauma splenectomy varies, with minimal existing data to guide practice. We aimed to investigate the association of LUQ drains with organ space surgical site infection (OS-SSI) after splenectomy. We hypothesized that LUQ drains after trauma splenectomy are associated with increased odds of OS-SSI. PATIENTS AND
methodsA retrospective study of adult blunt trauma patients who underwent splenectomy from 7/2018 to 6/2024 was performed. We excluded patients who survived <5 days after operation, and those with an intraoperatively identified pancreatic injury. Demographics, surgical details, and drain information were abstracted from the medical record. Inverse probability of treatment weighting (IPTW) was used to balance variables between patients who did and did not receive an LUQ drain after splenectomy. Multivariable logistic regression with IPTW was performed to estimate the association of LUQ drains with OS-SSI.
resultsOf 179 patients, 68% (n = 121) were male, the median age was 38 years (interquartile range 28, 55), and 27% (n = 48) received an LUQ drain. Patients with a drain were more likely to be male and overweight. Age, injury severity, use of damage control, and bowel injuries and resections were similar in patients with and without drains. LUQ drains were associated with increased adjusted odds of OS-SSIs (aOR 5.6, 95% confidence interval 1.7-18.3, p ≤ 0.01). Seven patients, all with drains, had a pancreatic fistula (7/48 vs. 0/131).
conclusionLUQ drains after splenectomy for blunt trauma were associated with increased odds of OS-SSIs. Given the high likelihood of unmeasured confounders and the inability to capture surgeons' complex decision-making in this study, randomized controlled trials are needed to assess the risks and benefits of LUQ drains after splenectomy.
