ASK DR QUAN WAI LEONG: ENDOSCOPY & GALLSTONES
August 7th, 2018

Endoscopy is a procedure where your doctor inserts a narrow flexible tube equipped with a camera through your mouth to examine your digestive tract. 

New advances in medical technologies allow endoscopists to do not only diagnostic procedures (identification and confirmation of disease situations) but also therapeutic (treatment of disease conditions such as removal of bile duct stones) endoscopies that would be minimally invasive and hence promote faster healing.

Join Dr Quan as he hosts a QnA session where he answers all your questions on endoscopy and gallstones.
