Abstract: Background: Prolonged postoperative hospital stay after cholecystectomy for acute cholecystitis may reflect baseline vulnerability and disease severity. We assessed preoperative factors associated with prolonged postoperative stay in a Peruvian emergency hospital. Methods: We conducted a retrospective cohort study of patients undergoing cholecystectomy for acute cholecystitis in 2024. All potentially eligible source records were screened. Prolonged postoperative stay was defined as >3 days from surgery to discharge. Adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) were estimated using modified Poisson regression with robust variance in a prespecified model restricted to preoperative variables. Results: Of 540 records screened, 422 patients were eligible. Median postoperative stay was 2.4 days (IQR, 1.0-3.8), and 158 patients (37.4%) stayed >3 days. Higher risk was observed for age 45-64 years (aRR, 1.51; 95% CI, 1.09-2.10), age ≥65 years (aRR, 1.95; 95% CI, 1.37-2.76), diabetes mellitus (aRR, 1.31; 95% CI, 1.02-1.67), and ASA IV-V status (aRR, 1.50; 95% CI, 1.04-2.16). Hypertension and active smoking showed inverse associations and require cautious interpretation. Postoperative complications occurred in 111 patients (26.3%) and were analyzed descriptively. Conclusion: Older age, diabetes mellitus, and higher preoperative ASA status were associated with prolonged postoperative stay. These findings warrant prospective validation and should not be interpreted as causal.
