Meckel’S Diverticulum

(Meckel’s diverticulum)

As Meckel’s diverticulum is called a congenital aneurysm in the distal ileum. It occurs in 2-3% of people. In general, it has a distance of up to 100 cm from the ileocecal valve and contains heterotopic gastric and / or pancreatic tissue. Symptoms are rare, they may be in circulation, intestinal obstruction and inflammation (diverticulitis). Diagnosis is difficult, often scintigraphy and a barium enema should be performed. Treatment consists of resection.

Symptoms are rare, they may be in circulation, intestinal obstruction and inflammation (diverticulitis). Diagnosis is difficult, often scintigraphy and a barium enema should be performed. Treatment consists of resection. Pathophysiology When the fetus Dottergang that draws from the terminal ileum to the navel and yolk sac is normally closed to the 7th week. If the portion that connects the ileum, not atrophied, resulting in formation of a Meckel’s diverticulum. This congenital diverticulum contains all layers of the normal intestine. At about 50% of diverticula are found ectopic gastric (and parietal cells that release hydrochloric acid) or pancreatic tissue, or both. Only about 2% of the carriers of a Meckel’s diverticulum develop complications. Although diverticula equally often occur in men and women, it comes to 3 times more likely to complications in men 2. Complications include: bleeding bowel obstruction Divertikulitiden tumors bleeding are more common in young children (<5 years) and then occur when the acid formation in the ectopic gastric mucosa of the diverticulum causes ulceration in the adjacent ileum. A bowel obstruction can occur at any age but is more common in older children and adults. In children, the most common cause is an intussusception of the diverticulum. A closure may also be caused by adhesion, volvulus, impacted debris, tumors, or by incarceration in a hernia (Littré hernia). Acute Meckel's diverticulitis can occur at any age, but has its peak age in later childhood. Tumors, incl. Carcinoid tumors, a total not frequent, but occur v. a. while in adults. Symptoms and complaints in all ages, a bowel obstruction by crampy abdominal pain, nausea and vomiting manifested. Typical of the acute Meckel diverticulitis are abdominal pain and tenderness under or next to the navel. These are often accompanied by vomiting, and overall results except for the localization of pain a clinical picture like appendicitis. In children, repeated episodes of painless rectal bleeding bright red can occur, which is not as hard as a rule, that it leads to circulatory shock. And adults may experience bleeding, typically more than melena than as fresh blood. Diagnosis As per the symptoms bleeding scintigraphy in CT in pain The diagnosis is difficult and the investigation methods used are based on the symptoms. If deflected in a rectal blood flow to the suspected source of bleeding in Meckel's diverticulum, a 99m Tc-pertechnetate scintigraphy can identify an ectopic gastric mucosa and thus the diverticula. In patients with abdominal pain and local Druchschmerzhaftigkeit a CT should be used with oral contrast agents. If vomiting and signs of the closure feature prominently, you will use Abdomenleeraufnahmen lying down and upright. Whenever a normal appendix is ??found, the suspicion towards Meckel's diverticulum must steer. Sometimes the diagnosis can be made only in an operative exploration on a suspected appendicitis.
