Exploratory Laparotomy After Routine Cardiac Surgery: Results From 17,000 Patients.
Observational study in World journal of surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThis study sought to elucidate the incidence and risk factors for exploratory laparotomy ("exlap") after cardiac surgery, its associated perioperative complications, and its impact on long-term survival.
methodsThis was an observational study of consecutive STS index cardiac operations between 2010-2022, excluding circulatory arrest, transplant, and multivalvular cases. The cohort was dichotomized by the incidence of exlap in the postoperative period.
resultsA total of 17,362 patients were included, of which 77 (0.5%) underwent an exlap. Postoperatively, the exlap group required more intra-aortic balloon pumps (IABP), vasopressors, and rescue therapy (i.e., methylene blue or hydroxocobalamin) than the no-exlap group. The exlap group had higher operative mortality, stroke, prolonged ventilation, sepsis, dialysis, mediastinal re-exploration, and pRBC transfusions. On multivariable logistic regression, total number of postoperative pressors, use of rescue therapy, preoperative IABP, white race, chronic dialysis use, and history of cerebrovascular accident were associated with the need for postoperative exlap. On multivariable logistic regression, exlap was an independent risk factor for operative mortality (OR 3.67, 95% CI: 1.95-6.88, p < 0.001). Among patients surviving to discharge, Kaplan-Meier survival estimates were lower in the exlap group compared to the no-exlap group (p < 0.001), with 5-year survival being 58.9% (42.6-74.2) in the exlap group versus 84.4% (83.8-85.0) in the no-exlap group.
conclusionsExploratory laparotomy is rare after open-heart surgery, and it was performed for gastrointestinal complications that occurred in the context of other severe postoperative complications. Several factors were associated with the need for exlap, including increasing age, pre-existing renal and vascular disease, and pre- and post-operative shock.
