소화성 궤양 합병증으로 응급수술을 시행한 환자에서 수술 후 합병증 예측인자로서 POSSUM-physiological Score의 유용성

Abstract

Purpose: The POSSUM (Physiological and Operative Severity Score for Enumeration of Mortality and Morbidity) score was developed to predict post-operative mortality and morbidity rates. The aim of this study was to validate the POSSUM physiologic score (POSSUM-P) in emergent operations for peptic ulcer complications. Methods: We retrospectively collected data on patients who underwent emergent operation for peptic ulcer complications at Boramae Hospital between January 2003 and April 2009. The data included patients` characteristics (underlying disease, medication, duration of symptoms), operative characteristics (operation method, Morbidity, and mortality) and the items for the POSSUM-P (basic information (age, sex, etc.), circulatory and respiratory signs, electrocardiogram, blood pressure, hemoglobin, white blood cell count, potassium level, sodium level, urea level and Glasgow coma scale). The POSSUM-P was calculated and compared according to the morbidity and mortality. Results: One hundred and twelve patients were included. As for operation methods, primary repair (48.2%) was most common, followed by truncal vagotomy with pyloroplasty (27.7%). Thirty-seven patients had morbidities including wound infections (20), pneumonias (14), fluid collections (9), and so on. Eight patients died due to sepsis or pulmonary edema. The means of POSSUM-P were significantly different between patients with and without mortality (37.8 vs. 19.2, P < 0.001) and between patients with and without morbidity (26.7 vs. 17.3, P < 0.001). Those were different between patients with and without postoperative postoperative pneumonia and wound infection (P=0.002 and P=0.029, respectively). Conclusion: The POSSUM physiologic score Could help to predict the mortality or morbidity after emergency operation for complications of peptic ulcer disease, especially postoperative pneumonia or wound infection.
