Intussusception in adults is rare. Even more unusual is jejunal intussusception secondary to a heterotopic pancreas. The presence of pancreatic tissue in an ectopic location and lacking contiguity with the main pancreatic gland is defined as pancreatic heterotopia. It is very rarely symptomatic and usually diagnosed incidentally during surgical intervention for other conditions. We report the case of a 78-year-old lady who presented with a history of constipation, abdominal pain, and vomiting. A CT scan revealed features of a proximal jejunojejunal intussusception secondary to a small soft tissue density lead point. After laparotomy and segmental jejunal resection, histopathology confirmed the diagnosis of ectopic pancreatic tissue as the lead point. Although uncommon, heterotopic pancreatic tissue should be included in the differential diagnosis for proximal small bowel intussusception.
成人肠套叠很少见。更为罕见的是继发于异位胰腺的空肠套叠。胰腺组织出现在异位位置且与主胰腺腺体不连续被定义为胰腺异位。它很少有症状，通常在因其他病症进行手术干预时偶然被诊断出来。我们报告一例78岁女性病例，她有便秘、腹痛和呕吐病史。CT扫描显示近端空肠-空肠套叠的特征，继发于一个小的软组织密度的套叠起始点。剖腹手术和节段性空肠切除术后，组织病理学证实套叠起始点为异位胰腺组织。尽管不常见，但异位胰腺组织应列入近端小肠套叠的鉴别诊断中。
