Colon and Rectal Surgery

Screening and Diagnostics

Oftentimes, patients come to our offices with symptoms and are unsure of what their medical issue might be. To make sure that we make the right diagnosis, our physicians use a number of screening tools including:

Colonoscopy

A colonoscopy is an examination of the colon that is used to find the cause of your symptoms. In order for our doctors to have a clear view of your colon and a successful examination, we often ask patients to take a number of steps to clean out the bowels. This includes:

  • Diet – on the day prior to your procedure, you should follow a clear liquid diet. Do not drink or eat anything within 8 hours of the procedure.
  • Medications – if you have regularly prescribed medicines, ask your Tufts Medical Center doctor whether or not you should take them before this procedure.
  • Bowel preparation – starting at 2:00pm on the afternoon prior to your procedure, you will need to either follow the Magnesium Citrate Prep, PEG Prep or Miralax prep to clean out the bottle. Your doctor will give you instructions for this process. 

Most patients are able to go home 1-2 hours after their procedure, under supervision of a responsible adult.

Proctology Examination

A proctology examination is a minor procedure used to check the lower colon and rectum for any abnormalities such as hemorrhoids, polyps, fistulas and fissures. The examination usually takes only 3-5 minutes but we do ask you to take steps to clear the lower bowel so that we can see everything clearly.

After your evening meal on the day before your appointment, you should not eat any solids until after the exam is complete. Two hours before your examination administer a Fleet enema. View additional instructions.

Transit Time Study

A transit time study is a test of intestinal function that is designed to determine the time it takes for markers to pass through the gastro-intestinal tract. Over the course of 3 days, your doctor will ask you to swallow three capsules that will contain small markers which are visible on X-rays of the abdomen.

The transit time is calculated by counting the number of markers on each X-ray film. Learn more about the preparation for this procedure.
