Prognostic Scoring System in Colonic Diverticular Perforation

Abstract

Objective: To evaluate whether the prognostic scoring system is appropriate for colonic diverticular perforation as well as colonic perforation of other etiologies. The scoring system for colonic diverticular perforation was also evaluated. 【Methods】 We retrospectively evaluated the data of 81 consecutive cases of colonic perforation at our institution. Patient information, laboratory results, perioperative information, and the Prognostic Scoring System data were compared between the 27 cases of diverticular perforation and 54 cases of colonic perforation of other etiologies. The data were also compared between the living and deceased surviving and non-surviving patients with diverticular perforation. 【Results】A statistically significant difference between the group with diverticular perforation and that with colonic perforation of other etiologies was observed only in the interval from onset to the hospital visit. Between the surviving and non-surviving patients with diverticular perforation, statistically significant differences were observed in the data on preoperative organ disorders, Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM), and the Mannheim peritonitis index. 【Conclusion】 The prognostic scoring system is applicable and useful for the evaluation of patients with colonic diverticular perforation in addition to those with colonic perforation of other etiologies.
