Expertise
In Minimally Invasive and Robotic Colorectal Surgery

From screening colonoscopies to major surgeries to remove cancer, Dr Tan’s passion is in melding the intricate art of surgery, with the sacred profession of being a cancer surgeon. A certified console surgeon of the da Vinci® robotic surgical system, her subspecialty interests are in robotic and minimally invasive colorectal surgery, particularly in the treatment of advanced and recurrent colon and rectal cancers. During her tenure at SGH, she performed numerous minimally invasive lateral pelvic lymph node dissections for patients with advanced rectal cancer, as well as complete mesocolic excision surgery for colon cancer. She was also part of a multi-disciplinary team who performed the first (in SGH) robotic pelvic exenteration for a patient with advanced rectal cancer.

To date, she has performed more than 500 major colorectal resection surgeries for both colorectal cancer and benign colorectal conditions. In addition, since 2016, she has been part of the multi-disciplinary Inflammatory Bowel Disease (IBD) Team at SGH. As one of the IBD surgeons in the team, she has performed many life-saving surgeries for patients with both ulcerative colitis and crohn’s disease.
