Purpose: Unplanned reoperation (URO) after radical gastrectomy for gastric cancer (GC) mostly results from serious postoperative complications. At present, there is still controversy over the predictive factors for URO. Our goal was to identify the risk factors for URO and to investigate its potential impact on long-term survival.
Patients and methods: We included 2,852 GC patients who underwent a gastrectomy. Multivariate logistic regression analyses were performed to determine the risk factors for URO. Patients were randomly selected from the non-URO group by 1:4 propensity score matching with multiple parameters with patients from the URO group. The survival disparity of 34 URO patients and 136 non-URO patients was examined using the Kaplan–Meier method and the multivariate Cox proportional hazard model.
Results: The incidence of URO was 1.4% (39/2, 852). The primary cause of URO was intra-abdominal bleeding (53.9%, 21/39). Multivariate logistic regression analyses revealed that male gender (OR = 4.630, 95% CI = 1.412–15.152, P = 0.011), diabetes (OR = 4.189, 95% CI = 1.705–10.290, P = 0.002), and preoperative hypoproteinemia (OR = 2.305, 95% CI = 1.079–4.923, P = 0.031) were independent risk factors for URO. With regard to early surgical outcomes, patients undergoing URO had a longer hospital stay (P < 0.001), higher incidence of postoperative complications (P < 0.001), and greater mortality (P < 0.001) compared with the non-URO group. No significant correlation was found between URO and cancer-specific survival in univariate (P = 0.275) and multivariate (P = 0.090) survival analyses.
Conclusion: Male gender, diabetes, and preoperative hypoproteinemia were suggested as independent risk factors for URO. URO was associated with longer hospital stay and increased perioperative mortality, but might not be correlated with long-term mortality.
