Patterns of negative trauma laparotomy worldwide: a sub-analysis of a global dataset.
Observational study in European journal of trauma and emergency surgery : official publication of the European Trauma Society, 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
purposeTrauma remains a major contributor to global disability. While the trauma laparotomy can be a life-saving procedure in abdominal injury, a select proportion are performed with no pathology identified intra-operatively, potentially exposing patients to unnecessary morbidity. We aimed to assess the global prevalence of negative laparotomy and identify any influencing factors at both the patient- and system-level.
methodsThis was a secondary analysis of the GOAL-Trauma study, a multicentre prospective international observational study on trauma laparotomy patients, conducted from April to December 2024. We defined a negative laparotomy as where no intra-abdominal injuries were identified during the index operation. A multivariable logistic regression was performed to identify predictive factors for a negative laparotomy.
resultsOf the 1769 patients included, 128 patients (7.2%) underwent a negative laparotomy. Regression analysis demonstrated that a penetrating mechanism of injury (OR 2.37, CI:1.53-3.69, p < 0.001) and a lower grade of surgeon (surgical registrar relative to consultant - OR 2.91, CI:1.90-4.47, p < 0.001) were independent predictors for negative laparotomy. Neither human development index nor hospital resource level impacted negative laparotomy rates.
conclusionOne in every fourteen trauma laparotomies performed in our global cohort was negative, with injury type and surgeon experience having a significant deterministic role. As trauma systems develop globally, recognition in the value of both training and a structured assessment pathway is paramount. The rate of negative trauma laparotomy, either institutionally or regionally, may act as a useful benchmark of trauma system performance and warrants further exploration.
