Abdominal Pain

Abdominal pain is an especially common and complex condition in adults and children with many possible causes. Our experienced doctor is able to go through your history, examination and tests to identify the cause of your pain and prescribe the correct treatment and medications. He has a special interest in adults and children with abdominal pain that is difficult to treat.

Painless Gastroscopy & Colonoscopy

Painless gastroscopy and colonoscopy is our doctor's special skill. Indeed, he is a Master of these procedures. His technique has evolved after many years of research and the use of a gentle touch that combines Japanese and Western styles of endoscopy. For maximum patient safety and comfort, sedation is given and the procedure is performed in a hospital setting. Oxygen is administered and continuous monitoring of blood oxygen levels and pulse rate is routine. Some patients prefer to have the procedure done awake and this request can be accommodated on a case-by-case basis. Without sedation, "awake" gastroscopy and colonoscopy may be slightly uncomfortable but tolerable. This painless technique has been requested particularly by fellow doctors and by patients who demand no sedation and yet do not mind a mild degree of discomfort.

Patient safety is our highest priority

Our track record is perfect for diagnostic gastroscopy and colonoscopy: there have been zero perforations and no sedation mishaps in over 10,000 examinations. Our doctor's personal philosophy is reflected in our motto: "Perfection and Professionalism in Practice". As of May 2014, our doctor's Polyp Detection Rate is an astonding 44% for the last 100 cases, attesting to his careful and meticulous examination technique. Dr Yap's attitude is that every colonoscopy should be conducted meticulously, as if it was his own colon !!
