Upper Endoscopy (OGDS)
OGDS-picUpper endoscopy examination enables visualization of the upper digestive tract which includes oesophagus, stomach and first few centimeters of the small intestine. It is performed by introducing a flexible fiberoptic scope through the mouth to the stomach and intestine. The scope will be passed gently through the tract.

The actual procedure will only take about 5 minutes. Patients are usually sedated by an injection just before the procedure. Most patients will not experience any discomfort or pain during the procedure if they are sedated. As endoscopy allows rapid and accurate evaluation of the digestive tract, it is now an accepted and preferred assessment tool for many gastroenterologists.

Tissue samples can also be taken and endoscopic treatment can be delivered eg. polyp removal and treatment of bleeding ulcers during the procedure. Upper endoscopy especially diagnostic endoscopy procedures ( purely for evaluation and not treatment) are safe if it is performed by experienced and trained specialists.

Indications for upper endoscopy
– Upper abdominal discomfort or pain which failed to respond to treatment.
– Upper abdominal discomfort or pain with evidence of serious organic disease such as loss of weight or appetite.
– Difficulty in swallowing.
– Persistent or refractory reflux symptoms.
– Evaluation of abnormal radiological abnormality.
– Family history of gastrointestinal cancer.
– Known to have or family history of any diseases that is a predisposition to gastrointestinal cancer such as familial
– Adenomatous polyposis.
– Confirmation of healing of peptic ulcers.

capsule-endoscopyWhat is a capsule endoscopy?
It’s a non-invasive test to diagnose cause of obscure GI bleeding and other small intestinal disorders such as Crohn’s disease. It can also be used to diagnosed gastroesophageal reflux disease.The procedure entails swallowing a capsule with the size of a pill that has a camera.

Picture will be taken as it moves through the intestine and will be transmitted to a small data recorder that the patient wears on his/her belt. These pictures are later downloaded into a computer and interpreted by a physician.

Indications for capsule endoscopy
– Unexplained GI bleeding
– Chronic abdominal pain
– Small bowel tumours
– Inflammatory bowel disease
– Malabsorption syndromes

Esophageal pH monitoring
Gastroesophageal reflux is a common condition that is due to backflow of stomach contents and acid into the esophagus and sometimes into the mouth or airways. Esophageal pH monitoring is a diagnostic test to confirm the disease by temporarily installing a probe at the lower part of the esophagus to record the pH for 24 hours.

Colonoscopy
Colonoscopy is done to enable visualization of the lower intestinal tract which includes the rectum, large intestine, caecum and sometimes the last few centimeters of the small intestine.It is done by introducing a long flexible tube with fiberoptics through the anus. Abnormalities on the lining of the large intestine such as inflammation, ulcers, growths, abnormal blood vessels and diverticulum can be detected. Since the large intestine is soiled with faeces, patients must perform proper bowel cleansing before the examination. The bowel must be specially prepared for at least 2 days prior to the examination by restricting their diet and taking laxatives. These steps are of utmost importance for a desirable outcome. (please refer to our doctors or nurses for further advice).

Indications for colonoscopy
– Presence of blood in the stools.
– Rectal bleeding.
– Evaluation of any radiological abnormalities.
– Colon cancer screening.
– Family history of cancer of the large intestine.
– Disorders which has predisposition to colon cancer.
– Chronic diarrhoea of unexplained cause

– Loss of weight or appetite without obvious cause.

Sigmoidoscopy
Sigmoidoscopy is similar to colonoscopy but the examination will only cover the distal part of the large intestine. It will enable a thorough examination of the wall of the large intestine and also provide tissue sampling. It will take only about 5-10 minutes and sedation need not be used.
Indications for Sigmoidoscopy
– To evaluate and diagnose diseases confined to the distal part of the large intestine.
– To assess fresh per rectal bleeding in younger patients.
– Colorectal cancer screening among patients with normal or low risk.

Haemorrhoid band ligation
Haemorrhoid is a very common condition that can be asymptomatic but may also present with extremely distressing manifestations like profuse rectal bleeding, anal mass or pain. Haemorrhoid band ligation is a simple daycare procedure to treat internal haemorrhoids which are chronic, symptomatic or have developed complications. The procedure is usually done under direct visualisation with the help of a proctoscope.It is usually painless, does not require sedation and takes only 5-10 minutes.
