Cognitive Changes After Surgery in the Elderly: Does Minimally Invasive Surgery Influence the Incidence of Postoperative Cognitive Changes Compared to Open Colon Surgery?
Cognitive changes in the elderly are common after surgery. It is not known if minimally
invasive or laparoscopic surgery can prevent these changes. A study will be conducted on
patients scheduled to have abdominal surgery. The patients will have cognitive evaluations
before and after surgery. A small amount of blood, about 2 tablespoons, will be collected no
more than 5 times in 6 months. The results will be analyzed to determine if there are
changes between those having open surgery versus patients having laparoscopic or minimally
invasive surgery, and if these changes coincide with cognitive changes.
