About this study
Official title: Cognitive Changes After Surgery in the Elderly: Does Minimally Invasive Surgery Influence the Incidence of Postoperative Cognitive Changes Compared to Open Colon Surgery?
A study will be conducted to determine if there is any cognitive benefit in elderly patients having open versus minimally invasive colon cancer surgery.
Read the detailed description
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.

Questions about this trial
What is this clinical trial studying?
An observational study of Confusion and Inflammation, run by New York Hospital Queens at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 19 Jun 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Mitchell Chorost, MD (718-670-1185, mchorost@nyp.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Confusion (time frame: 6 Months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01623297, which also lists 24 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jun 2012.
