摘要
AIM： To evaluate the clinical significance of preand intra-operative colonoscopy for the detection of synchronous lesions in colon cancer.METHODS： Two hundred and sixty-five pre-operative and 51 intra-operative colonoscopic evaluations were performed in 316 colorectal cancer patients who underwent curative resection from January 2001 to June 2006. The incidence and characteristics of synchronous lesions and their influence on surgery were evaluated.RESULTS： Two hundred and eighty-two synchronous lesions were detected in 124 （39.2%） of 316 patients including all lesions regardless of their histologic type. True adenomatous polyps were found in 91 （28.8%） of 326 patients, and 27 （5.4% of all patients） patients had synchronous colon cancers. The preoperative identification of synchronous lesions altered the planned surgery in 37 （14.0%） of 265 patients. In 18 patients among the surgically removed cases, the lesions were removed by extending the resection range. Further segmental resection or polypectomy through enterotomy was necessary in 29 patients. Nineteen （37.2%） of 52 intraoperative colonoscopy cases had synchronous lesions. Additional surgical procedures including segmental bowel resection and polypectomy with enterotomy were necessary in 7 （23.7%） of 52 intraoperative colonoscopy cases to remove the lesions.CONCLUSION： Synchronous colorectal polyps or cancer are frequent and their preoperative detection is important for optimal surgical planning and treatment. Intraoperative colonoscopy is a useful option in cases where a preoperative colonoscopy is not feasible.
