This procedure involves passing a flexible telescope (endoscope) to investigate the inside of the stomach / bowel. Mr Jayanthi performs
1. Oesophago Gastro-Duodenoscopy (OGD) or Upper Gastro-Intestinal (GI) Endoscopy
This procedure is performed either under sedation or a local anaesthetic throat spray or under general anaesthetic in specific situations. It involves passing the endoscope on the top of the tongue, into back of the throat and then into the oesophagus (gullet) and stomach and duodenum (first part of the bowel). This takes about 5 – 10 mins to complete. Some biopsies may be taken at the time of the procedure to help with diagnosis. Throughout the procedure, you can breathe freely. In fact focussing on the breathing makes the procedure more comfortable.
You will feel a bit bloated as some wire is put into the stomach to enable good views of the inside lining of the structures. Main complications include, bleeding and perforation of the gullet. However, there are very rare and an OGD in the vast majority a safe procedure. All the patients after a diagnostic OGD can go home the same day.
2. Flexible Sigmoidoscopy
This procedure is performed either awake or under sedation. It involves passing the endoscope through the tail end to examine the lower part of the bowel. This can take from 10 to 30 mins to complete. The risks of this procedure are bleeding and perforation of the bowel. The risk of perforation increase if the bowel have any abnormality.
You will require to have either a rectal or an oral medicine to clear the bowel of stools. This will ensure good views of the internal lining of the bowel. If there are any polyps, these can be excised at the same time. The risk of bleeding and perforation increase if there were any polyps requiring excision. All the patients after a diagnostic examination and after minor polyp excisions will be able to go home the same day of the procedure.
Remember you will not be able to drive after having sedation for these procedures. So ensure you have some one picking you up from the hospital if you have chosen to have sedation for these procedures.
