What Is a Meckel's Diverticulum?

[Overview]

Michael's diverticulitis

[Overview]

Congenital malformation left over due to the yolk duct not being closed. Occurred on the opposite side of the mesangium from 25 to 100 cm from the ileocecal segment in the terminal ileum. Simple Michael's diverticulum generally does not cause clinical symptoms. Once pathological changes occur, inflammation, ulcers, bleeding, perforation, and intestinal obstruction can occur, and have different clinical manifestations. The diagnosis is difficult, and can usually be diagnosed during barium examination or intraoperatively.

diagnosis

1. Lower abdomen pain is the lower right, accompanied by nausea or vomiting, with varying degrees of fever; diverticulum ulcers, which may have different degrees of intestinal bleeding.

2. The right lower abdomen has tenderness, rebound pain, and muscle tension near the midline; when purulent perforation may show signs of acute diffuse peritonitis.

3. The total number of white blood cells and neutrophil count increased.

4. X-ray digestive tract barium examination can show diverticulum.

5. Nuclide scans can show diverticulum shadows of ectopic gastric mucosa.

6. When acute appendicitis is diagnosed and no lesions are found in the appendix during surgery, 100 cm of the terminal ileum should be routinely explored to avoid missed diagnosis of Michael's diverticulopathy.

[Treatment]

1. Diverticulum basement diameter less than 1.0cm, can be treated according to appendectomy.

2. The base of diverticulum is wide and can not be simply ligated. The diverticulum can be resected along the intestinal canal or the diverticulum can be removed and part of the intestinal canal is anastomosed.
