Meckel's diverticulum is the most common congenital anomaly of the small bowel and is caused by the incomplete obliteration of the omphalomesenteric duct during the eighth week of gestation.
We report the case of a 51-year-old male who presented to the emergency department with epigastric pain, vomiting, and abdominal distension. Clinically, he had a high intestinal obstruction without any mechanical cause on computed tomography scan. A median laparotomy was proposed.
An internal ileum hernia was identified twisted around a giant Meckel's diverticulum with a mesodiverticular artery, coursing from the base of the mesentery to the diverticulum. A small bowel segmental resection was performed, containing the diverticulum. Histology revealed a 15-cm long Meckel's diverticulum with no heterotopic mucosa.
Small bowel obstruction due to an internal ileum hernia twisted around a giant Meckel's diverticulum with a mesodiverticular artery is very rare, and its diagnosis is challenging, requires a high level of suspicion, and it is only performed by exploratory surgery.
梅克尔憩室是小肠最常见的先天性异常,由妊娠第8周时卵黄管未完全闭塞引起。
我们报告了一例51岁男性患者,因上腹部疼痛、呕吐和腹胀就诊于急诊科。临床上,他在计算机断层扫描中表现为高位肠梗阻且无任何机械性病因。建议行正中剖腹术。
发现一个内疝性回肠围绕一个巨大的梅克尔憩室扭转,该憩室有一条憩室系膜动脉,从肠系膜根部延伸至憩室。进行了包含憩室的小肠节段性切除。组织学检查显示一个15厘米长的梅克尔憩室,无异位黏膜。
内疝性回肠围绕一个带有憩室系膜动脉的巨大梅克尔憩室扭转导致的小肠梗阻非常罕见,其诊断具有挑战性,需要高度怀疑,且仅通过探查性手术进行诊断。
