Frequently Asked
Questions
When Should Someone Be Referred To A Colorectal Surgeon?
Patients are commonly referred after symptoms such as rectal bleeding, a change in bowel habit, abdominal or anal pain, or an abnormal finding on a scan or screening test. A referral is an assessment, not a decision that surgery is needed. See our colorectal care services for an overview of the conditions assessed.
What Is The Difference Between A General Surgeon And A Colorectal Surgeon In Singapore?
The Singapore Medical Council maintains a Register of Specialists in which General Surgery is the registrable specialty. Colorectal surgery is a subspecialty practised within general surgery rather than a separate register. Dr Chok is a Registered Specialist in General Surgery who practises with a subspecialty focus on colorectal surgery, which is why both titles appear alongside his name.
Can I Verify Dr Chok’s Specialist Registration Independently?
Yes. The Singapore Medical Council publishes a Register of Medical Practitioners and a Register of Specialists, both of which can be searched online at smc.gov.sg. Patients travelling from overseas are welcome to confirm a doctor’s registration status through that register before arranging a consultation.
What Do The HMDP Award And PelvEx Collaborative Membership Involve?
The Health Manpower Development Plan (HMDP) is a Singapore Ministry of Health award that funds senior clinicians to undertake further training at overseas institutions. Dr Chok received the award in 2019 and trained at the Royal Marsden Hospital in London. The PelvEx Collaborative is an international research group studying pelvic exenteration surgery for advanced pelvic cancers, to which he has contributed as an author.
Will My Consultation And Any Procedure Take Place At The Same Location?
Not necessarily. Consultations take place at Aelius Surgical Centre at Mount Elizabeth Medical Centre or Parkway East Medical Centre. Procedures requiring an operating theatre or an inpatient stay are carried out at an affiliated hospital where Dr Chok holds privileges. The arrangement for your case is confirmed during consultation.
Does Dr Chok Manage Urgent Or Emergency Surgical Cases?
Yes. His practice includes emergency surgical treatment for presentations such as bowel obstruction from colorectal cancer, intussusception and bowel perforation. For urgent situations, our contact lines operate 24 hours, and we also provide urgent care coordination for patients requiring immediate attention.
Is Dr Chok On My Insurance Panel?
Panel and extended panel arrangements vary between insurers, policies and riders, and they change over time. Please check directly with your insurance provider for their current list of panel doctors in Singapore. Our team can also assist with insurance-related queries when you submit an enquiry.
