Abstract

The incidence of intussusception in adults is quite low. A preoperative diagnosis was quite difficult due to the atypical clinical features, but the success rate of preoperative diagnosis of intussusception has improved with the advances in abdominal US and CT. However, the value of colonoscopy in making a preoperative diagnosis is unclear. The incidence of multiple primary cancer of the colon and rectum can vary widely. We report a case of intussusception in a patient who had synchronous cecal and sigmoid colonic cancer. A 71-year-old man was visited our hospital for diarrhea and general weakness. The abdominal US and CT revealed a mass lesion in the cecal area. Preoperative colonoscopy confirmed the lesion to be cecal cancer with a synchronous sigmoid colon cancer. In conclusion, the rarity of these synchronous cancers may result in a misdiagnosis. Therefore, a preoperative colonoscopy or postoperative colonoscopy might be useful.
