“…The clinical significance of synchronous polyps or cancer may be different based on these epidemiologic factors. Most prior studies on perioperative colonoscopy have been performed in Western countries; there are only a limited number of reports in Asia [9,10] . The present study was performed to evaluate the status of synchronous colon cancer in Korea and efficacy of perioperative colonoscopy.…”

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 316 patients, and 17 (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 19 patients. Nineteen (37.2%) of 51 intraoperative colonoscopy cases had synchronous lesions. Additional surgical procedures including segmental bowel resection and polypectomy with enterotomy were necessary in 7 (13.7%) of 51 intraoperative colonoscopy cases to remove the lesions.

“…Nosso grupo de assintomáticos com idade acima de 50 anos teve a taxa de 29 % de adenoma, semelhante à encontrada por outros autores que foi de 21,3% (20). Lesões sincrônicas malignas no cólon ocorreram somente nos portadores de CCR sintomáticos, correspondendo à alíquota de 2,4%, que pode ser vista na Tabela-7 e é semelhante à encontrada por outros autores, variando de 2,12 a 4 % 21,22,23,24 . A nossa distribuição topográfica do CCR seguiu o padrão habitual para população de risco médio tanto no Grupo A como no grupo B, como podemos ver na Tabela-5 predominando portanto em cólon esquerdo, incluindo reto, correspondendo a 66 e 69 % respectivamente e diferente do padrão inverso alcançado na HNPCC e ou na síndrome de Lynch, como se observa na literatura 25,26,27,28,29,30,31,32,33,34,35,36,37 .…”
