OBJECTIVE: To investigate the clinical and pathological features of synchronous @entity14 and explore the specificity of treatment for those @entity1 . METHODS: A retrospective evaluation of 326 @entity1 with primary @entity14 were performed. The @entity1 were divided into two groups: single cases (303 @entity1 ) and synchronous cases (23 @entity1 , index @entity5 and second @entity5 ). Clinical characteristics, routine pathological findings in the two groups were compared statistically. RESULTS: There was no difference in location of the lesions between the single cases and the index lesions of synchronous cases, while the differentiation and Ducke stage of index lesions were better than those in single cases. The secondary @entity5 of synchronous cases showed better grades and stages than those of single cases. The frequencies of complicating @entity652 and @entity1127 in synchronous cases were higher significantly than those in single cases, with the rate of 34.8% and 78.3%, 11.6% and 42.2%, respectively. All malignant lesions were resected radically, and @entity1127 (56.9%) were electro-resected under colonoscopy at 2 approximately 3 months after the @entity189 were radically resected. Of the @entity1 complicated with @entity652 , 79.1% (34 cases) were given one-stage local resection or local colectomy and the rest were given second stage electro-resection. CONCLUSIONS: For the clinical and pathological features of synchronous @entity14 , it is essential to perform a complete evaluation of all @entity14 , establish an individual surgical treatment and follow-up in time.
