The small intestine is the longest portion of the digestive tract. It runs from the stomach to the colon.
Meckel's diverticulum is one of the most common congenital abnormalities. It occurs when the connection between the intestine and the umbilical cord doesn't completely close off during fetal development. This results in a small outpouching of the small intestine, know as a Meckel's diverticulum. In most cases, Meckel's diverticula do not cause any problems. In a small number of patients however, these diverticula can become infected (diverticulitis) cause an obstruction of the intestine, or cause bleeding from the intestine. The most common symptom of Meckel's diverticulitis is painless bleeding from the rectum. The stools may contain fresh blood or may look black and tarry. Diverticulitis, or infection, of a Meckel's diverticulum is often mistaken for appendicitis.
Treatment of a Meckel's diverticulum involves resection of the involved portion of the small intestine. Often, symptoms from a Meckel's diverticulum are thought to be due to appendicitis- and the Meckel's diverticulum is discovered only after the operation has begun. While the patient is deep asleep and pain-free (general anesthesia), an incision is made in the right side of the lower abdomen.
The small intestine is found and the Meckel's diverticulum is removed. The intestine is repaired and the incision is closed.
Intravenous fluids will be given until the patient is able to eat by mouth (after bowel sounds are heard). A nasogastric tube may be in place to empty the stomach. Antibiotics may be given to prevent or treat infection. Discharge from the hospital can be expected within a week after surgery, barring complications.
