Abstract

Background: The Naples Prognostic Score (NPS) has proven efficacy as a prognostic tool for postoperative outcomes in patients undergoing surgery for neoplastic diseases. However, the role of the NPS score in inflammatory surgical diseases has not yet been studied. We aimed to evaluate NPS predictive value in patients undergoing colectomy due to diverticulitis. Methods: A single-center retrospective study including all patients who underwent colectomy for diverticulitis between July 2008 and March 2020 was established. Patients' demographics, clinical and surgical data were recorded and analyzed. Patients were scored on a scale of 0-4 and received one point for preoperation albumin <4 g/dL, cholesterol ≤180 mg/dL, Neutrophil to Lymphocyte Ratio >2.96, and Lymphocyte to Monocyte ≤4.44. Results: Out of 3292 patients admitted because of diverticulitis during the study period, 159 patients (4.83%) underwent colectomy. Of those patients, fifty patients were eligible for NPS analysis. 35 patients (70%) were females with a mean age of 62.81 ± 14.51. Thirty-two (64%) patients underwent an elective operation. The postoperative complications rate was 36% (N = 18). The mortality rate was 6% (N = 3). ROC showed a strong association between the NPS and mortality (area = .88, P = .03) and wound infection (area = .78, P = .01). In patients who underwent urgent surgery, there was an association between NPS and re-operation ( P = .04). There was a correlation between NPS and Clavien-Dindo score (Spearman's coefficient = .284, P = .045). Conclusions/Discussion: The Naples prognostic score is an effective tool for predicting postoperative complications in patients undergoing colectomy for diverticulitis. It may assist the surgeon in deciding on extent of the operation for diverticulitis and in elective cases also on timing.
