In five years, 15 patients were seen with anal carcinomas presenting as perirectal abscesses or fistulas. Nine patients had acute abscesses without histories of chronic anorectal disease, and six patients had long-standing anorectal disease in which carcinoma developed. Operative exploration was needed to establish the diagnosis in all patients. Early definitive surgery would certainly have prevented most if not all of the cancers from developing in the group with chronic anorectal disease.
在五年时间里，共诊治了15例以直肠周围脓肿或肛瘘形式出现的肛管癌患者。9例患者为急性脓肿，无慢性肛肠疾病史，6例患者有长期肛肠疾病并发展为癌症。所有患者均需进行手术探查以明确诊断。对于患有慢性肛肠疾病的患者群体，早期进行确定性手术肯定能预防大部分甚至所有癌症的发生。
