Procedures Performed At The DEC
A colonoscopy procedure allows physicians to examine the entire colon, from the rectum to the lower end of the small intestine. Using a lighted flexible tube with a camera that transmits pictures of the colon on a video stream, the doctor examines the colon for ulcers, swelling (inflammation) or polyps (small growths). The physician can also take small tissue samples (biopsy) to look for infection, illness, early signs of cancer, and also remove polyps. Removed polyps are examined closely to determine if they are pre-cancerous. During a colonoscopy procedure patients receive a mild sedative and pain medication for comfort. A Registered Nurse assists the doctor during the procedure and a Sedationist/Anaesthetist monitors vital signs.
A flexible sigmoidoscopy is very similar to a colonoscopy and allows the physician to examine the rectum up into the descending colon. Sigmoidoscopy allows physicians to look for causes of diarrhoea, constipation or abdominal pain, and early signs of cancer in the descending colon and rectum. Polyps can also be removed during this procedure. This procedure is mildly uncomfortable and may be performed in the Doctor’s office.
Upper Endoscopy (Gastroscopy also known as Panendoscopy)
An upper endoscopy (gastroscopy) enables physicians to see inside the oesophagus, stomach and duodenum. This diagnostic tool is used to analyse swallowing difficulties, nausea, vomiting, reflux, bleeding, indigestion, and abdominal pain or chest pain. Biopsies can be obtained for further analysis during a gastroscopy. A sedative and pain medication is normally used for patient comfort.
Oesophageal Dilatation is performed during Panendoscopy, to open up a stricture (narrowing) of the oesophagus. During Panendoscopy, a fine guiding wire is passed through the endoscope down the oesophagus and through the blockage. The endoscope is slightly pulled back to allow the dilating tube to be inserted next to the blockage. The dilator then slides along the guiding wire allowing the Gastroenterologist to expand the blocked oesophagus. This procedure is performed while the patient is sedated, resulting in little if any discomfort for the patient.
This procedure is useful for treating numerous Upper stricture-producing GI conditions such as:
- Barrett’s Oesophagus
- Gastro Oesophageal Reflux Disease (GORD)
- Oesophageal Cancer
- Dysphagia due to narrowing
- Hiatus Hernia with narrowing
- Eosinophilic Oesophagitis
Small Bowel Enteroscopy
Small bowel enteroscopy allows physicians a direct look at the small intestine using a lighted flexible tube with a tiny camera that transmits pictures of the small intestine to a video screen. The Doctor can examine the small intestine for ulcers, inflammation or disease. Physicians can also take small samples (biopsy) of the tissue to look for infection, illness or early signs of cancer. During the procedure patients receive a mild sedative and pain medication for comfort. A Registered Nurse assists the doctor during the procedure and a Sedationist/Anaesthetist monitors vital signs.
A liver biopsy is performed to obtain a sample (biopsy) of liver tissue for examination under a microscope. From the results of a liver biopsy physicians are able to determine the type and severity of liver disease or liver damage, evaluate the presence of tumours or infection, or check existing conditions such as hepatitis or liver scar tissue (cirrhosis). During liver biopsy the Doctor injects a local anaesthetic around the biopsy site. A thin needle is inserted into the edge of the liver to remove a tissue sample. A Registered Nurse assists the doctor during the procedure and a Sedationist/Anaesthetist monitors vital signs. Patients are closely monitored for several hours prior to discharge.
Endoscopic Retrograde Cholangio Pancreatography (ERCP)
ERCP allows physicians to examine gastrointestinal bile duct systems of the liver, gallbladder and pancreas. Useful in diagnosing and treating problems causing jaundice or abdominal pain, many pancreas and bile duct system problems can be identified and corrected during ERCP. Tumour diagnosis and biopsy, stone removal, and using endoscopic balloons or stent placement can open strictures or scarring. Performed in a procedure fitted with radiographic equipment, ERCP employs a lighted flexible tube with a tiny camera that transmits pictures to a video screen. X-rays are also used with the endoscope to obtain a complete picture of the bile duct system. During an ERCP procedure patients receive a mild sedative and pain medication for comfort. A Registered Nurse assists the doctor during the procedure and a Sedationist/Anaesthetist monitors vital signs.
Percutaneous Endoscopy Gastrostomy Placement (PEG)
Placement of a gastrostomy tube is required for patients who are unable to consume sufficient kilojoules. These patients are unable to eat or swallow enough nutrition for their daily activities. The gastrostomy tube is placed through the abdomen into the stomach and can be used for nutrition, fluids or medications. Gastrostomy can be used for a short time or long-term for patients with diagnoses such as facial trauma, dysphagia and tumours of the head and neck. Physicians will use a lighted flexible tube through the mouth and into the stomach to place the tube. During gastrostomy tube placement procedure patients require a mild sedative and pain medication for comfort. A Registered Nurse assists the doctor during the procedure and a Sedationist/Anaesthetist monitors vital signs. After the endoscopy procedure patients and/or carers must learn how to use and care for the tube.
