An intussusception due to colonic adenocarcinoma has sometimes been reported. However, to the best of our knowledge, reports of intussusception due to rectal adenocarcinoma are extremely rare. In this report, the case of a young man with rectal adenocarcinoma causing intussusception is described. A 24-year-old man visited a hospital complaining of abdominal pain, and an upper rectal cancer was diagnosed by colonoscopy. Computed tomography showed intussusception caused by a large tumor in the pelvis and absence of distant metastases. Locally advanced rectal cancer causing intussusception was diagnosed, and a low anterior resection was performed. Intraoperatively, repair of the invagination could not be accomplished easily; therefore, the repair was abandoned. Instead, the tumor was removed en bloc to avoid dissemination of the cancer. Histopathologically, the tumor was diagnosed as a poorly differentiated adenocarcinoma, pStage IIA. The patient has no evidence of recurrence at 10 mo after the operation.
有时会有结肠腺癌导致肠套叠的报道。然而，据我们所知，直肠腺癌导致肠套叠的报道极为罕见。在本报告中，描述了一名患有直肠腺癌并导致肠套叠的年轻男性病例。一名24岁男性因腹痛就诊于医院，经结肠镜检查诊断为上段直肠癌。计算机断层扫描显示盆腔内有一个大肿瘤导致肠套叠，且无远处转移。诊断为局部进展期直肠癌导致肠套叠，遂行低位前切除术。术中，无法轻易完成肠套叠的修复；因此，放弃了修复。取而代之的是，将肿瘤整块切除以避免癌症扩散。组织病理学检查显示，肿瘤被诊断为低分化腺癌，p分期为IIA期。术后10个月，患者无复发迹象。
