Colorectal Surgery

Endoscopy (Colonoscopy)

Colorectal cancer is a preventable disease. Most colorectal cancers begin with a non-cancerous growth (also called polyp) which over time can become cancer if left untreated. Colonoscopy with removal of polyps can reduce the risk for colorectal cancer. In addition, colonoscopy is commonly used to evaluate other gastrointestinal symptoms, such as rectal and intestinal bleeding, abdominal pain, or changes in bowel habits. It is also recommended that colonoscopies should be performed in individuals without symptoms to check for colorectal polyps or cancer. A screening colonoscopy is recommended for anyone 50 years of age and older, and for anyone with parents, siblings or children with a history of colorectal cancer or polyps.

Colonoscopy is an outpatient procedure in which the inside of the large intestine (colon and rectum) is examined. To complete a successful colonoscopy, the bowel must be clean so that the physician can clearly view the colon. Instructions will be given to the patient for bowel preparation in advance of the procedure. It is very crucial for the patient to follow the instructions because without proper preparation, the colonoscopy will not be successful and the test may have to be repeated.

During a colonoscopy, a colonoscope (flexible instrument about 1/2 inch in diameter) is advanced by experienced colorectal surgeon to view the lining of the rectum and the colon. If necessary, small amounts of tissue can be removed for analysis (a biopsy) at the same time polyps can be identified and entirely removed.

Bangkok Hospital Phuket has provided routine colonoscopy with the latest advanced in endoscopic technology using magnified colonoscopy with narrow band imaging. This special technology allows more accurate diagnosis and treatment of colorectal problems without the need for a major operation.
