Abstract:
Objective To understand the pathogenic characteristics of intra-abdominal infection after appendecto-my in patients with appendicitis.Methods Clinical data of patients undergoing appendectomy in a hospital from January 2013 to December 2015 were analyzed retrospectively,pathogenic characteristics,treatment,and prognosis of patients with intra-abdominal infection were analyzed.Results A total of 431 patients undergoing appendectomy were investigated,38 (8.82%)developed intra-abdominal infection.36 strains of pathogenic bacteria were isolated, 34 (94.44%)of which were gram-negative bacteria,mainly Escherichiacoli(n=29,80.55%);2 (5.56%)strains were gram-positive bacteria,1 of which was Staphylococcusaureus,and the other was Enterococcusavium.The re-sistance rates of 29 strains of Escherichia coli to commonly used antimicrobial agents (amoxicillin,piperacillin,ti-carcillin,cefuroxime,ceftazidime,and cefalotin)were 72.41%-93.10%,none of strains were found to be resistant to piperacillin/tazobactam,meropenem,imipenem,and amikacin.Conclusion Escherichiacoli is the most common pathogen causing intra-abdominal infection after appendectomy and it has high resistance rates to most commonly used antimicrobial agents,piperacillin/tazobactam,amikacin,and carbapenems are recommended for treating intra-abdominal infection after appendectomy.
