While intussusception is relatively common in children, it is a rare clinical entity in adults, where the condition is almost always secondary to a definable lesion.
Thirteen cases of intussusception occurring in individuals older than 16 were encountered at our institute between 1981 and 1994.
Presenting signs/symptoms included recurrent bowel obstruction, intermittent pain, and red blood per rectum. Correct preoperative diagnosis was made in six patients using colonoscopy, flexible sigmoidoscopy, upper gastrointestinal (GI) series and computed tomography (CT). At surgery the lead point was identified in the small intestine in eight cases, in the colon in four cases, and one small intestinal intussusception was considered idiopathic. Twelve patients underwent laparotomy and one patient was both diagnosed and treated by colonoscopy alone.
Adult intussusception is an unusual cause of bowel obstruction. The likelihood of neoplasia, particularly in the colon as a cause, is high. Operative management is thus almost always necessary.
肠套叠在儿童中相对常见，但在成人中是一种罕见的临床病症，成人肠套叠几乎总是继发于可明确的病变。
1981年至1994年间，我院共收治16岁以上肠套叠患者13例。
主要症状包括反复肠梗阻、间歇性疼痛和直肠便血。6例患者通过结肠镜检查、乙状结肠镜检查、上消化道造影和计算机断层扫描（CT）在术前得到正确诊断。手术中，8例套叠的起始点位于小肠，4例位于结肠，1例小肠套叠被认为是特发性的。12例患者接受了剖腹手术，1例患者仅通过结肠镜检查得到诊断和治疗。
成人肠套叠是肠梗阻的罕见病因。肿瘤形成的可能性很高，尤其是在结肠作为病因的情况下。因此，几乎总是需要进行手术治疗。
