Meckel's Diverticulum
Meckel's Diverticulum samer kareem 5,811 Views • 2 years ago

The differential diagnosis for this child's painless hematochezia includes Meckel's diverticulum as well as vascular malformations. Meckel's diverticulum results from a failure of the vitelline duct to obliterate during the first 8 weeks of gestation, leaving behind a blind pouch often containing ectopic gastric tissue. Meckel's diverticulum classically affects children age ~:2 but can also occur in older children or even adults. Young children are more likely to experience painless bleeding due to mucosal irritation from gastric acid; adolescents and adults are more likely to have signs of obstruction. A technetium-99 nuclear scan will identify the diverticulum, which is usually located in the right lower quadrant of the abdomen within 2 feet of the ileocecal valve. Technetium-99 concentrates in the parietal cells of the diverticulum and stomach. The scan is also known as "Meckel's scan" due to its high specificity. A symptomatic Meckel's diverticulum is generally treated with surgical resection.

They are over 90% effective against sexually transmitted diseases (STDs), and of course, they help to reduce the risk of pregnancy by 98%. Some guys claim that they’re not comfortable to wear, which is why some companies have come up with new condoms that have a more natural fit and provide pleasure for both partners.
