Surgical forms of treatment for these conditions include:
Diagnostic procedures, such as a colonoscopy, are very important in colorectal surgery, as they can tell the physician what type of diagnosis should be given and what procedure should be done to correct the condition.
Other diagnostic procedures used by colorectal surgeons include: proctoscopy, defecating proctography, sigmoidoscopy. In recent times, the laparoscopic method of surgery has seen a surge of popularity, due to its lower risks, decreased recovery time, and smaller, more precise incisions achieved by using laparoscopic instruments.
Going through colorectal surgery will definitely temporarily affect your bowel movements and functions. The speed of food travelling through the colon will decrease and bloating can be expected.
Gallbladder polyp is a common finding on abdominal imaging such as ultrasonography. Most of these polyps are not cancerous and only a small proportion of these polyps will progress to cancer. Unfortunately, it is rarely curable and prognosis is poor with less than 5% of patients with confirmed gallbladder cancer surviving more than 5 years . Thus it is important to decide which gallbladder polyps should be treated. The most accepted guideline now is for gallbladder polyps that are more than 10mm to be removed.

Dr Kan graduated from Manchester University Medical school and went on to obtain further qualifications from Addenbrookes Hospital. Thereafter, he pursued post-graduate senior surgical fellowships at world-renowned centres - National Cancer Centre and the Cancer Institute (Tokyo, Japan), Prince of Wales Chinese University Hospital (Hong Kong) and Princess Alexandra Hospital (Brisbane, Australia). These fellowships have trained him to be well-versed with thoracoscopic resections for oesophageal and gastric cancers and MIS for the benign oesophageal disease. Minimally invasive/ keyhole surgery is a highly complex surgery and Dr Kan is one of a few surgeons in Asia who can successfully treat stomach and oesophagea cancer using this method.
He served as a clinical lead in Upper GI focusing on MIS in general surgery and a surgical lead in trauma and bariatric surgical services at Alexandra Hospital and Ng Teng Fong General Hospital. There, he established a multidisciplinary team to perform laparoscopic gastric bypass and sleeve gastrectomies on severely obese patients.
Dr Kan’s other clinical interest includes bariatric/metabolic surgery for the obese patient. He has been performing laparoscopic gastric bypass since 2002.
On top of his clinical practices, Dr Kan regularly shares his knowledge and experiences and has presented at medical conferences all over the world (USA, UK, France, India, Singapore, Australia, Philippines, Vietnam, and Thailand).
