Intussusception is defined as invagination of a proximal segment of gastrointestinal tract into distal segment and is an uncommon pathology. It is more common in children. In the adult population, it is often due to a polyp or tumor. We report an interesting case of a vanishing colonic polyp in a 55-year-old man who presented with a three-month history of intermittent right abdominal pain, altered bowel habit, and weight loss. Colonoscopy demonstrated a large, elongated polyp in the ascending colon, which vanished during attempts to intubate proximally. A computed tomography scan showed a lipomatous polyp in the distal ileum confirmed on a repeat colonoscopy. The patient proceeded with surgical resection, and histology confirmed the polyp to be an ileal submucosal lipoma. There is literature on ileocolic intussusceptions secondary to ileal submucosal lipoma; however, our case is interesting and unique in that the intussusception was seen and reduced during the colonoscopy.
肠套叠被定义为胃肠道近端节段套入远端节段，是一种罕见的病理情况。它在儿童中更为常见。在成人中，通常是由息肉或肿瘤引起的。我们报告了一例55岁男性患者，其结肠息肉消失，该患者有三个月间歇性右腹痛、排便习惯改变和体重减轻的病史。结肠镜检查显示升结肠有一个大的、细长的息肉，在向近端插管时息肉消失。计算机断层扫描显示回肠末端有一个脂肪瘤性息肉，再次结肠镜检查得以证实。患者接受了手术切除，组织学检查证实息肉为回肠黏膜下脂肪瘤。有关于回肠黏膜下脂肪瘤继发回结肠套叠的文献报道；然而，我们的病例有趣且独特之处在于，在结肠镜检查过程中观察到并复位了肠套叠。
