In the developed world, small bowel obstruction accounts for 20% of all acute surgical admissions. The aetiology for majority of these cases includes postoperative adhesions and herniae. However, a relatively uncommon cause is a Meckel's diverticulum. Although this diagnosis is primarily reported in the adolescent population, it should also be considered in adults.
In the present report, we present a rare case where a fit and healthy 74-year-old gentleman, with no previous history of abdominal surgery, presented with the cardinal symptoms and signs of small bowel obstruction as the result of a Meckel's diverticulum encircling his terminal ileum. Initial investigations included a supine abdominal x-ray showing dilated loops of small bowel and computerised tomographic imaging of the abdomen, which revealed a stricture in the terminal ileum of unknown aetiology. At laparotomy, multiple loops of distended small bowel were seen from the duodeno-jeujenal junction to the terminal ileum, which was encircled by a Meckel's diverticulum. The Meckel's diverticulum was then divided to release the obstruction, mobilised and subsequently removed. Finally, the small bowel contents were decompressed into the stomach and the nasogastric tube aspirated, before returning the loops of bowel into the abdomen in sequence. The patient made a good postoperative recovery and was discharged home 5 days later.
This report highlights the importance of considering a Meckel's diverticulum as a cause of small bowel obstruction in individuals from all age groups and especially in a person with no previous abdominal pathology or surgery.
在发达国家,小肠梗阻占所有急性外科住院病例的20%。这些病例大多数的病因包括术后粘连和疝气。然而,一个相对不常见的病因是梅克尔憩室。尽管该诊断主要报道于青少年人群,但在成年人中也应予以考虑。
在本报告中,我们呈现了一例罕见病例,一名74岁身体健康的男性,既往无腹部手术史,因梅克尔憩室环绕其回肠末端而出现小肠梗阻的主要症状和体征。初始检查包括仰卧位腹部X光片显示小肠肠袢扩张,以及腹部计算机断层扫描成像,结果显示回肠末端有一病因不明的狭窄。在剖腹手术中,从十二指肠空肠交界处至回肠末端可见多个扩张的小肠肠袢,其被一个梅克尔憩室环绕。然后将梅克尔憩室切断以解除梗阻,游离并随后切除。最后,将小肠内容物减压至胃内并抽吸鼻胃管,之后依次将肠袢放回腹腔。患者术后恢复良好,5天后出院。
本报告强调了将梅克尔憩室视为所有年龄组小肠梗阻病因的重要性,尤其是对于既往无腹部病变或手术史的患者。
