Patients are usually referred to a gastroenterologist by a primary care doctor. You should see a gastroenterologist if you have any symptoms of a digestive health disorder or if you need a colon cancer screening.

Endoscopy is a nonsurgical procedure used to examine a person's digestive tract. During an upper endoscopy, an endoscope is easily passed through the mouth and throat and into the oesophagus, allowing the doctor to view the oesophagus, stomach, and upper part of the small intestine.

A colonoscopy is an outpatient procedure in which the inside of the large intestine (colon and rectum) is examined. A colonoscopy is commonly used to evaluate gastrointestinal symptoms, such as rectal and intestinal bleeding, or changes in bowel habits.

Flexible sigmoidoscopy is a procedure used to investigate problems with your lower bowel or rectum, including pain, bleeding or inflammation. A sigmoidoscopy can also be used to diagnose bowel cancer, or to remove non-cancerous growths, called polyps, from your bowel.

Before your operation

On being referred to us for the gastroenterology service you will be contacted by our friendly staff to arrange a convenient appointment usually within two weeks of the referral.  Please be aware your first initial appointment with the gastroenterologist may be by telephone due to Covid.  

At your initial consultation you will be assessed by either Dr Agrawal (consultant gastroenterologist, Mr Balchandra (consultant upper GI and bariatric surgeon or Mr Khetan (consultant colorectal surgeon). You can ask any questions around your care during this appointment. Your initial appointment includes a full assessment and may include an intimate examination. Your appointment takes approximately 20 minutes. You may be required to have further investigations which the consultant will discuss with you. If an endoscopy procedure is required this will be discussed in detail and if bowel preparation is required this will also be discussed in detail.

Following the appointment you will be given a date for your procedure and an appointment for a covid test.  The covid test will be 3 to 5 days prior to your appointment.  At your covid swab appointment you will be given your bowel preparation (if required) and all the relevant information leaflets to take home with you to read.  You will be contacted by telephone or text with the results of your covid test.

On the day of the procedure

Your procedure will be performed by one of the consultants in our endoscopy suite.

On arrival please ring the number on your letter and one of our nursing staff will collect you from the car park and will support you through our pre-admission process. Prior to your procedure nursing staff will take your blood pressure and do vital observations. If you are having a flexible sigmoidoscopy an enema will be administered.  

You will then be seen by the consultant, prior to your procedure, and you can ask any questions related to the procedure. The consultant will then discuss the risks and benefits of the procedure and you will sign the consent form with the consultant.

You will then be taken to the endoscopy suite for the procedure which usually takes 15 to 30 minutes depending on which procedure you are having.

After the procedure you will be given post procedure instructions regarding after care advice. You will also be given a copy of your endoscopy report. A contact number is also provided for if you have any concerns.

If you do have any concerns or problems after the procedure please contact the surgery and speak to a member of our admin or healthcare team so that arrangements can be made for you to be seen immediately.
