Meckel's diverticulum is the congenital anomaly of the gastrointestinal tract affecting about 2% of the population. It is a true diverticulum containing all layers of the ileum wall. Heterotopic tissue is frequently present (25%): gastric mucosa, duodenal mucosa, jejunal mucosa and pancreatic tissue. Meckel's diverticulum is localized about 50 cm from the ileo-colic valve on the external border of the ileum. Most of Meckel's diverticula are clinically silent; clinical symptoms (19%) are in cases of complications such as: strangulation of the bowel in a ring formed by the diverticulum, intussusception of the diverticulum into the ileum, volvulus, incarceration of the diverticulum in hernia, tumour originating in the diverticulum. The diagnosis of Meckel's diverticulum is very difficult. The most useful in the diagnosis are plain abdominal radiographs, barium studies, CT, sonography and scintigraphy Abdominal sonography shows a tubular fluid structure localized far from the coecum. The wall of the diverticulum is swollen and in the lumen are chyme or fat.
梅克尔憩室是一种胃肠道先天性异常，影响约2%的人群。它是一个真正的憩室，包含回肠壁的所有层。常存在异位组织（25%）：胃黏膜、十二指肠黏膜、空肠黏膜和胰腺组织。梅克尔憩室位于回肠距回盲瓣约50厘米处的回肠外侧缘。大多数梅克尔憩室临床上无症状；临床症状（19%）出现在并发症的情况下，如：憩室形成的环导致肠绞窄、憩室套入回肠、肠扭转、憩室嵌顿于疝、起源于憩室的肿瘤。梅克尔憩室的诊断非常困难。诊断中最有用的是腹部平片、钡剂造影、CT、超声检查和闪烁扫描。腹部超声检查显示一个远离盲肠的管状液性结构。憩室壁肿胀，腔内有食糜或脂肪。
