Feasibility of E-PASS score to predict postoperative complications in laparoscopic nephrectomy.

ABSTRACT

PURPOSE: To evaluate the usefulness of E-PASS score to predict postoperative complications after laparoscopic nephrectomy. METHODS: Between 2008 and 2020, 424 patients (179 patients simple nephrectomy, 158 patients radical nephrectomy, 87 patients donor nephrectomy) who underwent laparoscopic nephrectomy in our clinic, were included in the study. Patient groups separated according to the presence of postoperative complications were compared retrospectively regarding demographic, clinical, intraoperative, and postoperative data, comorbidities, and E-PASS scores (PRS, SSS, and CRS). The relationship between postoperative complications and E-PASS scores was examined. RESULTS: Postoperative complications occurred in 43 (10.1%) of the patients. Age, previous abdominal/retroperitoneal surgery, radical nephrectomy rate of surgeries, operation time, amount of bleeding, need for blood transfusion, rate of conversion from laparoscopic surgery to open surgery, hospitalization time, E-PASS PRS, SSS, and CRS were statistically significantly higher in the group with postoperative complications. The cutoff value of the E-PASS CRS was - 0.2996 to predict the development of postoperative complications (AUC = 0.706; 95% CI 0.629-0.783; p < 0.001). According to multivariate analysis, presence of previous abdominal/retroperitoneal surgery (OR 2.977; 95% CI 1.502-5.899; p = 0.002), laparoscopic radical nephrectomy (OR 2.518; 95% CI 1.224-5.179; p = 0.012), conversion from laparoscopic surgery to open surgery (OR 4.869; 95% CI 1.046-22.669; p = 0.044) and E-PASS CRS > - 0.2996 (OR 2.816; 95% CI 1.321-6.004; p = 0.007) were found to be independent risk factors predicting postoperative complications. CONCLUSION: The E-PASS scoring system is an effective and convenient system for predicting postoperative complications after laparoscopic nephrectomy.
