Key Takeaway
Note that preoperative chronic corticosteroid exposure is associated with higher odds of mortality and sepsis in GI surgery.

This meta-analysis evaluates the impact of preoperative chronic corticosteroid exposure on outcomes for patients undergoing gastrointestinal surgery, excluding those with inflammatory bowel disease. The analysis included a large sample of 776,681 patients to assess mortality, sepsis, and surgical site infections (SSI).

The primary finding is that patients with prior corticosteroid exposure had significantly higher odds of 30-day mortality (aOR 1.51; 95% CI 1.26-1.81) and sepsis (aOR 1.40; 95% CI 1.36-1.43). Additionally, these patients showed higher odds of readmission (aOR 1.26; 95% CI 1.07-1.48), reoperation (aOR 1.32; 95% CI 1.10-1.59), and organ-space surgical site infection (aOR 1.26; 95% CI 1.16-1.37). Results for superficial and deep SSI were not statistically significant.

The authors note several limitations, including mixed exposure definitions, residual confounding, and low or very low certainty of evidence. Not all findings were consistent across sensitivity analyses. Because of these factors, associations cannot be attributed to corticosteroids alone or generalized to all gastrointestinal procedures. The findings may support more intensive perioperative risk stratification and postoperative monitoring for patients with a history of chronic corticosteroid use.

How this fits prior evidence

This meta-analysis addresses a gap in understanding how pre-existing conditions or treatments affect outcomes in surgical patients with sepsis. It specifically identifies a higher risk of mortality (aOR 1.51) and sepsis (aOR 1.40) in patients with chronic corticosteroid exposure. This finding complements the evidence that malignancy is a prognostic factor for higher mortality in sepsis (odds ratios up to 2.41) and that myocardial dysfunction occurs in patients with sepsis.

When a patient prepares for gastrointestinal surgery, every factor in their medical history matters. A large review of data from over 776,000 patients suggests that those who have been taking corticosteroids—medicines often used to manage inflammation—long-term before surgery may face higher risks. Specifically, these patients showed higher odds of developing sepsis, a dangerous and severe infection, and a higher risk of death within 30 days of their procedure.

The study also looked at other complications like being readmitted to the hospital, needing a second operation, or developing infections at the surgical site. While the evidence for these specific complications was less consistent, the link between prior steroid use and serious issues like sepsis was more consistent across different types of data checks.

It is important to note that the evidence for these findings is currently considered low to very low in certainty. Because the study used varied definitions for how patients were exposed to steroids, we cannot say for certain that steroids alone cause these issues. However, the findings suggest that doctors should carefully monitor patients who use these medications before and after surgery to manage potential risks.

What this means for you:
Long-term steroid use before gut surgery is linked to higher risks of sepsis and death in some patients.

Common questions

Does taking steroids before surgery increase the risk of infection?

The data shows that patients with a history of chronic corticosteroid use had higher odds of developing sepsis, which is a severe infection, after gastrointestinal surgery. The study also found higher odds of organ-space surgical site infections for these patients.

Are there risks of death for patients on steroids before surgery?

The analysis of over 776,681 patients found that those with prior chronic corticosteroid exposure had higher odds of 30-day mortality following their gastrointestinal procedure.

Will these findings change how doctors treat patients on steroids?

Because the evidence certainty is low or very low, these findings are not a definitive rule. However, they may help doctors better identify and monitor patients who are at higher risk for complications like sepsis or readmission after surgery.

BackgroundPreoperative chronic corticosteroid use has been associated with an increased risk of postoperative complications. However, its association with postoperative outcomes following gastrointestinal surgery remains unclear. This systematic review and meta-analysis aimed to evaluate this association.MethodsPubMed, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched from inception to September 1, 2026. Eligible observational cohort studies compared patients with and without preoperative chronic corticosteroid exposure; studies restricted to inflammatory bowel disease were excluded. Adjusted estimates were pooled using random-effects models with restricted maximum likelihood and Hartung-Knapp confidence intervals after outcome-specific exclusion of potentially overlapping cohorts. Risk of bias and certainty of evidence were assessed using the Risk of Bias in Non-randomized Studies of Exposures (ROBINS-E) tool and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, respectively.ResultsFourteen retrospective cohort studies were included, seven of which contributed to quantitative synthesis. Bariatric surgery accounted for 65.2% of reported participants. The primary mortality analysis included five studies comprising 776,681 patients after overlap exclusions. Preoperative exposure was associated with higher odds of 30-day mortality (adjusted odds ratio [aOR] 1.51, 95% confidence interval [CI] 1.26–1.81), readmission (aOR 1.26, 95% CI 1.07–1.48), reoperation (aOR 1.32, 95% CI 1.10–1.59), sepsis (aOR 1.40, 95% CI 1.36–1.43), and organ-space surgical site infection (SSI; aOR 1.26, 95% CI 1.16–1.37). No statistically significant associations were found for superficial or deep SSI. Mortality and sepsis associations persisted in corticosteroid-specific analyses; readmission, reoperation, and organ-space SSI findings were less consistent across sensitivity analyses. Individual SSI analyses included only two studies and predominantly reflected colorectal surgery. Composite outcomes were summarized narratively. Evidence certainty was low or very low.ConclusionsPreoperative chronic corticosteroid exposure, as defined in the included studies, was associated with higher odds of adverse postoperative outcomes. The associations with mortality and sepsis were more consistent across sensitivity analyses. Given the mixed exposure definitions and residual confounding, the observed associations cannot be attributed to corticosteroids alone or generalized to all gastrointestinal procedures. These findings may support careful perioperative risk stratification and postoperative monitoring in these patients.Systematic Review Registrationhttps://www.crd.york.ac.uk/PROSPERO/view/CRD420261359719, identifier CRD420261359719.
