We report three cases of adult intussusception due to advanced colorectal cancer that could be treated with elective laparoscopic resection without emergency treatment. Case 1: An 81-year-old man was given a diagnosis of transverse colon cancer. CT image revealed an intussusception at the site of the tumor, but no signs of bowel ischemia. In addition, since the patient was asymptomatic, we performed an elective laparoscopic right hemicolectomy. Case 2: A 76-year-old man was found to have rectal cancer. Although CT image led to a diagnosis of an intussusception at the site of the tumor, no signs of bowel ischemia were found and he had no symptoms. Thus, we performed an elective laparoscopic high anterior resection. Case 3: In a 49-year-old man with sigmoid colon cancer the CT image revealed an intussusception at the site of the tumor. No signs of bowel ischemia were found and he had only mild symptoms. As a result, we performed an elective laparoscopic Hartmann's operation. All three patients were discharged without any complications. Conclusion: If the symptoms are only mild in patients with adult intussusception due to colorectal cancer, elective laparoscopic resection without preoperative emergency management can be performed safely.
