The incidence of synchronous carcinoma of the colon and rectum is rising and ranges from 0.6 to 11% in the international literature. We present a study on 410 patients with colorectal cancer; 10 patients (2.4%) had synchronous carcinoma. The group of patients with synchronous carcinomas were older than the group with nonsynchronous carcinomas (70.5 versus 67.4 years). The choice of surgery depended on the involved portions of the colon and the distance between the lesions. For tumoral sites in 2 different segments was performed subtotal colectomy, in the other cases (cancers located on one segment) was performed segmental colectomy. The incidence of synchronous tumors is sufficiently high to suggest that the preoperative identification of lesions by either colonoscopy is important for the proper treatment of patients with carcinoma of the colon and rectum and moreover an so high incidence, more the risk of not recognising the disease, especially in the case of small lesions, emphasizes the importance of postoperative endoscopic and clinical controls.
结肠和直肠癌同时发生的发病率正在上升，国际文献报道其范围为0.6%至11%。我们对410例结直肠癌患者进行了一项研究；其中10例患者（2.4%）患有同时性癌。同时性癌患者组比非同时性癌患者组年龄更大（70.5岁对67.4岁）。手术方式的选择取决于结肠受累部位以及病变之间的距离。对于位于2个不同节段的肿瘤部位，施行次全结肠切除术，在其他情况下（癌症位于一个节段），施行节段性结肠切除术。同时性肿瘤的发病率足够高，这表明通过结肠镜检查对病变进行术前识别对于结肠和直肠癌患者的恰当治疗很重要，而且如此高的发病率，尤其是未识别出疾病的风险，在小病变的情况下更为突出，这强调了术后内镜检查和临床监测的重要性。
