Synchronous Colorectal Carcinoma
摘要
Purpose: The reported incidence of synchronous colorectal carcinoma ranged between 2-5%. The purpose of this study was to analyze the patients with diagnosis of multiple colon cancers and results of en bloc resection for synchronous colorectal cancers.Materials and Methods: From Jan 1999 to Dec 2008, a total of 1,583 patients underwent surgical resection of primary colorectal cancers by a single surgeon were reviewed. The incidence and characteristics of synchronous lesions were evaluated.Results: There were a total of 25 patients (1.58%) diagnosed as having synchronous colorectal carcinoma. Seventeen patients were male and eight patients were female. Age ranged from 49 to 84 years old, with an average of 69.7 years old. Synchronous colorectal cancer occurs at older age and occurs more frequently in the group of male. Operative mortality was 12% (3/25).Conclusion: Synchronous colorectal cancers are not infrequent. Surgeons should be alert about the possibility of presence of multiple lesions and be able to avoid second operation for missing lesion.
