General Surgery

The Department of Surgery takes pride in delivering integrated and coordinated transdisciplinary surgical care to our patients.

Our surgeons share similar values of wanting to deliver progressive and collaborative surgical care, putting patient safety first and being compassionate.

This is delivered through various subspecialties:

  • Breast
  • Bariatric
  • Colorectal
  • Endocrine
  • Hepatobiliary
  • Neurosurgery
  • Vascular
  • Upper Gastrointestinal

We believe in doing the best for our patients be it benign or breast cancer related issues. 
Breast surgery is a very personal affair. Our waiting time for a clinic appointment is generally below two weeks.  Urgent cases can be seen earlier. 
Holistic care is at the forefront of our minds. Our dedicated and experienced staffs are always at your service to walk this journey with you.

Colorectal services at KTPH are provided at a one-stop “Colorectal Centre” that offers comprehensive care in the diagnosis, treatment and support for patients with both benign and malignant (cancer) conditions relating to the bowel (colon, rectum and anal canal).

Our team offers a full range of diagnostic services including Colonoscopy, CT colonography, MRI scanning, Endorectal / endoanal ultrasonography and Anorectal Manometry. All Consultant Surgeons in our team are accredited bowel cancer screening colonoscopists for early detection and treatment.

KTPH Colorectal team uses innovative techniques and collaborative care to make surgery safe and to shorten the length of stay. All the surgeons are trained in advanced laparoscopic (keyhole) surgery, and two-thirds of all elective operations for bowel cancer are completed laparoscopically.

A successful Geriatric Surgical Service (GSS) for elderly patients since 2007 has resulted in improved surgical outcomes. The team has an established and effective enhanced recovery (ERAS) care program with a median length of stay of 5 days after major colorectal operations. The team has also introduced pelvic floor service for disorders like fecal incontinence, prolapse disorders and other functional bowel conditions.

Our close working relationship with medical and radiation oncologists from National Cancer Centre allows us to adopt a multidisciplinary approach for treatment of colorectal cancers. A bi-monthly multidisciplinary meeting discusses all cancer patients and also reviews outcome data.

Our team is dedicated to provide evidence based and compassionate care to all our patients.

The Endocrine Surgical Service within the Department of Surgery is headed by A/Prof Reyaz M. Singaporewalla. After going through post-graduate specialist surgical training in Singapore, Dr Singaporewalla was awarded the Ministry of Health Singapore’s prestigious Health Manpower Development Scholarship (HMDP), that enabled him to go for further hands-on specialization in endocrine and minimally invasive surgery under world renowned specialists, Prof Martin Walz in Germany and Prof Tom Lennard in UK.

After completing his HMDP, Dr Singaporewalla started the Endocrine Surgical Service in Khoo Teck Puat Hospital. He has initiated the Minimally Invasive Video-Assisted Thyroidectomy (MIVAT) procedure, and KTPH Endocrine Surgery is currently the only public healthcare institution offering this surgical procedure. He has also pioneered the concept of a ONE-STOP “Quadruple Assessment” Thyroid Clinic to allow a hassle-free, cheaper and faster evaluation of thyroid nodules (goitres).


  • Evaluation of neck lumps / nodes / cysts

    “Quadruple Assessment” Thyroid Clinic is a one-stop single day evaluation of thyroid nodules (Goitre): 

i) History & Clinical exam

ii) Thyroid hormone tests (T4, TSH)

iii) Bedside Ultrasound 

iv) Ultrasound guided aspiration of cysts or FNAC of solid nodules with on-site cyto-technician support

  • Surgery for Benign and Malignant Thyroid Pathology: 
    Total thyroidectomy +/- neck dissection 
    Completion thyroidectomy 
    Subtotal / Near total thyroidectomy 
    Minimally Invasive Video-Assisted Thyroidectomy (MIVAT) 
    Transaxillary Endoscopic Thyroidectomy (No Neck Scar)
  • Parathyroid Surgery (Primary & Secondary Hyperparathyroidism): 
    Conventional & Minimally Invasive Parathyroid Surgery
  • Adrenal Surgery: 
    Retroperitoneal laparoscopic 
    Open conventional approach  

Clinics slot for appointments

KTPH is the first hospital in Singapore to adopt this approach with the ESAT team commencing operations in November 2014. The ESAT team admits all general surgery acute and trauma patients during the daytime from Monday to Friday at 7.30am - 4.00pm. This novel approach allows for a dedicated consultant level service provision for critically ill patients that are admitted through the emergency department.   


Consultant led team dedicated to emergency surgical and trauma patients
Rapid assessment of critically ill surgical patients in emergency department 
Timely surgery for emergency surgical and trauma patients
Established collaboration with Interventional radiology and ICU for holistic care
Acute and elective endoscopy 
Three follow up clinics per week
