Risk factors for complications after appendectomy in adults

[摘要] BACKGROUND: Risk factors for adverse outcomes after the surgical treatment of appendicitis in adults are poorly defined. Accurate presurgical assessment of the risk of preoperative complications and mortality is important in planning surgical therapy.METHODS: All patients undergoing surgical intervention for appendicitis from January 2003 and January 2004 were selected for study. Independent variables examined included 11 putative preoperative risk factors and 4 intraoperative process measures. Dependents variables were complications. Stepwise logistic regression analysis was used for construct models predicting complications.RESULTS: There was a high risk in female (OR=1,97, 95%, IC-1,19-3,13), in appendix with perforation (OR=4,67 95%, IC-2,43-8,94), appendix without perforation (OR=3,32, 95%, IC-1,72-6,38), drainage (OR=17,54, 95%,IC-4,83-63,77) and ASA II (OR=1,53, 95%, IC 2,52-15,89).CONCLUSION: Four factors, in the logistic regression analysis, predicted a high risk of complications after the surgical treatment of appendicitis: female, necrosis with or without ruptured appendix, drainage and ASA Class II.
