I am Dr Quah Hak Mien, Colorectal Surgeon based in Gleneagles Hospital Singapore. I graduated from the University of Bristol (United Kingdom) in 1997. I received majority of my training in Singapore but had the opportunity to train overseas in Surgery at Glan Clwyd Hospital, United Kingdom in 2002. I obtained my Master of Medicine in Surgery from National University of Singapore in 2002. I became a Fellow of the Royal College of Surgeon of Edinburgh and a Fellow of the Academy of Medicine of Singapore in 2005. In 2006, I was awarded the SingHealth HMDP award for further training subspecialising in Colorectal Surgery. I went for my fellowship training at Memorial Sloan-Kettering Cancer Center in New York, USA in 2006. I had the privilege of working with Late Dr Douglas Wong, who was the Chief of Colorectal Service, focusing my clinical training and research on colorectal cancer, in particular, sphincter-preservative surgery for rectal cancer and recurrent pelvic cancer operations. My clinical interests are in the areas of prevention, endoscopic diagnosis and treatment of colorectal cancer. I was formerly Consultant at the Department of Colorectal Surgery, Singapore General Hospital. During my time in Singapore General Hospital, I held the post of Director of the Singapore Polyposis Registry. I was also Visiting Consultant to the Department of Surgical Oncology, National Cancer Centre of Singapore. I also held the concurrent appointment of Adjunct Assistant Professor with Duke-NUS Graduate Medical School. I have keen clinical interest in minimally invasive colorectal surgery. I am proficient in laparoscopic (keyhole) colorectal surgery and single incision laparoscopic (single keyhole) colorectal surgery. I am also one the few surgeons in Singapore accredited to perform Robotic-Assisted colorectal surgery. I am passionate about the training and education of young specialist doctors and medical students. I have conducted laparoscopic and endoscopic skill courses for local and overseas trainee surgeons. I have particular interest in the use of simulation machines for the training of laparoscopic and endoscopic surgical skills. I have also developed expertise in functional bowel disorders and pelvic floor disorders, such as patients suffering from chronic constipation, obstructed defaecation syndrome, faecal incontinence and rectal prolapse. Another area of my interest is that of perianal diseases and haemorrhoids (piles). I have published numerous academic articles in local and international peer-reviewed journals and book chapters, and I am a reviewer for the Singapore Medical Journal and Annals of Surgical Oncology.

Doctor, my father is 71 years old. In a day, he can defecate up to 5 times, but only a brownish liquid comes out of his bowels. We try to control his diet, providing vegetables and fruits which are rich in fiber, but still there is no solid stool coming out of him, only liquid stools. Why is this so, Doc?
Yesterday, I defecated 3 times and all three times, there was blood. My stomach hurt and after that, my anus was hot. Is there anything wrong with my anus or intestines, Doc?
Doctor, lately my bowel movement has red liquid in it, and I have pain in the lower abdomen radiating to the back of the hip. Please give me your advice.
Doctor, I am a 36 year old female. Why do I feel pain in my anus when I urinate? Is this due to infection, or something may be torn? Or is there likely another cause?
There is a lump in my father's anus that makes him bleed when he defecates. The doctor suggested he undergo surgery and it has been scheduled. I am worried. Does it mean the lump is dangerous if he has to undergo surgery, Doc? Is it cancer or haemorrhoids?
I have rectal cancer. These 6 months, I have been taking herbal medicines. My bowel movement is normal in terms of frequency, but it hurts and my feces are slimy and small. If I want to seek help from professional doctors, what is the first step I should take? Will I need to undergo a surgery, Doc?
Doctor, what is the solution for obstructed bowel movement? I haven’t defecated for 5 days. My stomach bloats and it is hard, but the stool cannot come out.
Is there any way to treat recurring haemorrhoids? It recurs if I eat spicy food. On the other hand, I love spicy food.
Good afternoon, Doctor. I have had a diarrhoea problem for 2 weeks now. How do I treat this?
