A small number of patients manifest wound infections several months to several years after their operations. A study was undertaken to delineate the clinical characteristics of patients whose infections became apparent after a prolonged time interval from surgery. Twenty-six patients were admitted to the New York Hospital-Cornell University Medical Center, with wound infections that occurred more than six months postoperatively. There were three distinct groups. The first group consisted of patients with Staphylococcus aureus infections related to superficial stitch abscesses. The second group comprised patients with pacemaker infections; S epidermidis was the most frequently recovered organism. The third group consisted of patients with more clinically significant infections. These infectious complications followed genitourinary, gastrointestinal, and biliary surgery. The findings of this study suggest that most of these infections are caused by organisms introduced into the wound at the time of surgery; these organisms may become active because of alterations in the host's resistance.
少数患者在手术后数月至数年出现伤口感染。开展了一项研究以描述那些在手术很长时间间隔后出现明显感染的患者的临床特征。26名患者入住纽约医院 - 康奈尔大学医学中心，术后6个月以上发生伤口感染。有三个不同的组。第一组由与浅表缝线脓肿相关的金黄色葡萄球菌感染患者组成。第二组包括起搏器感染患者；表皮葡萄球菌是最常分离出的微生物。第三组由具有更具临床意义感染的患者组成。这些感染并发症发生在泌尿生殖系统、胃肠道和胆道手术后。这项研究的结果表明，这些感染大多是由手术时引入伤口的微生物引起的；这些微生物可能由于宿主抵抗力的改变而变得活跃。
