I am Dr Mark Wong, Senior Consultant, General & Colorectal Surgeon practicing at Mount Elizabeth Novena Hospital Singapore and Mount Alvernia Hospital Singapore. My special interests are in minimally invasive (laparoscopic) and robotic surgery for both cancer and benign bowel disorders. Prior to starting my private practice, I practiced at the Department of Colorectal Surgery at Singapore General Hospital, where I pursued my interests in minimally-invasive (robotic and laparoscopic) colorectal cancer surgery and functional disorders (piles, constipation and incontinence). I was the longest-serving Director of the SGH Pelvic Floor Disorders Service. In this position, I led a multidisciplinary team of specialists, comprising colorectal surgeons, gynaecologists and urologists to provide holistic care for patients with pelvic floor disorders, including incontinence, chronic constipation and organ prolapse. In 2016, I was appointed Director of the SGH Gastrointestinal Function Unit, where I led a team of gastroenterologists and surgeons to evaluate patients with functional gastrointestinal disorders. I am well-versed in laparoscopic and robotic surgery for both cancer and benign disorders, proctology (piles, abscess, fistula and fissure), advanced therapeutic endoscopy (gastroscopy and colonoscopy) and functional bowel disorders (constipation and incontinence). I have worked with colorectal surgeons throughout Europe, USA and Asia, gaining a global perspective in treating patients. I am an opinion leader in the field of minimally invasive (laparoscopic and robotic) colorectal cancer and pelvic floor surgery, having been invited to lecture at numerous international colorectal meetings. I have also mentored and trained doctors from all across Southeast Asia, including Bangladesh, Myanmar, the Philippines and Vietnam. I am a dedicated educator and was appointed Adjunct Assistant Professor at the Duke-NUS Graduate Medical School and Senior Clinical Lecturer at the Yong Loo Lin School of Medicine, NUS. I was faculty of the Singhealth General Surgery Residency Programme and have contributed to maintaining high standards in surgical education.

Hello, Doctor. I want to ask. I feel so much pain when I defecate, there was once I saw blood. I read an article online that maybe there is a boil in my anus. If it is so, how do I treat this, Doc?
Doctor, my grandfather was diagnosed with stage-4 anal cancer and has undergone several chemotherapy sessions. I read an online article that said cancer is a hereditary disease. Are there any tips for me to avoid the risk of having anal cancer? Thank you
My uncle has rectal cancer and now we are considering chemotherapy. But he is currently complaining about having smelly liquid discharge from his anus. Does it mean his disease has worsened, Doc?
Doctor, I have bowel obstruction, and sometimes it is hard for me to defecate. I feel like there is a lump in my anus, but I am not sure either because I have never seen a doctor. When I cannot defecate, I take laxatives. Is this normal? Do I need to see a doctor?
Doctor, I always have diarrhea if I eat spicy food. Is this normal? Can it be cured?
Doctor, my father has colon cancer. Now he defecates through a hole in his stomach. My question is, is this permanent, Doc? What can I do to ease his pain because sometimes I can see from his facial expressions that he is struggling with the pain. He said it is difficult for him to defecate.
My father was diagnosed with colorectal cancer when he was 71. I am his daughter, and I am 35 years old. I want to ask, am I at risk to inherit this cancer? What are the signs of colorectal cancer that I should watch out for? Do you have any advice to prevent it, Doc?
Doctor, can piles be totally cured? When I take medication for it, it keeps recurring. Is there any advice, doc?
