Final answer:
A Meckel's diverticulum is typically discovered during surgery for diverticulitis.
Step-by-step explanation:
A Meckel's diverticulum is typically discovered during surgery for diverticulitis. Diverticulitis is a digestive disease in which tiny pouches in the wall of the large intestine become infected and inflamed. The infection and inflammation of the pouches (diverticulitis) occur in about 10 to 25 percent of people with diverticulosis and is more common at older ages. Surgery may be necessary to treat severe cases of diverticulitis or to address complications such as abscess formation or perforation of the colon.
