食管憩室是较多见的食管良性疾患之一,根据一些国外文献报道,少数病例可能导致食管癌变,但国内文献尚无报告。我院最近有一食管中段外牵性憩室病例,在连续四年多的观察中,发现于原憩室基础上发生癌变。兹将此例的观察治疗经过报告如下。 Esophageal diverticulum is one of the more common benign disorders of the esophagus. According to some foreign reports, a few cases may lead to esophageal canceration, but there is no report in the domestic literature. In our hospital recently, there was a case of external esophageal diverticulum in the middle esophagus. During the observation for more than four consecutive years, it was found that cancer occurred on the basis of the original diverticulum. The observational treatment of this case is reported below.
