Colorectal Surgery Profile Image

Colorectal Surgery

Colorectal surgery is a field in medicine, dealing with disorders of the rectum, anus, and colon.

Surgical forms of treatment for these conditions include: colectomy, ileo/colostomy, polypectomy, strictureplasty, hemorrhoidectomy (in severe cases of hemorrhoids), anoplasty, and more depending on the condition the patient has.

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.

Colon Cancer Is Not Just For Old People! Here's What Millennials And Gen-Xers Need To Know

People normally associate colorectal cancers with older people. This is true to a certain degree. 80% of newly diagnosed colorectal cancers are in the above 70 age group. These are what surgeons call sporadic cancers.

For young people in their 30s and 40s, getting struck with colorectal cancer is simply shocking. At the prime of their lives and at the peak of their careers, they are diagnosed with a potentially fatal disease.

I wrote this article to help shed some light on colorectal cancers in young people. I want to explain the cause and characteristics of this cancer, and what you can do to detect the cancer early.

In Singapore, anal fissures are (sadly) quite common. 

A 24-year-old female reader asked a question through DxD's Ask A Doctor form. She believes that she has an anal fissure. Her suspicion were aroused by the pain she experienced while passing motion. She felt that her skin was tearing, but she did not see any blood in her stools. 

She wanted to find out how are anal fissures treated and if she needs to seek further help. Here's what Dr Seah, an experienced GP had to say.

Based on your age and your 6 years of symptoms, and assuming you have no family history of colorectal cancers, the odds of your symptoms being due to a tumour are low. However, a screening colonoscopy is still your best bet in excluding a potentially serious condition. Discuss ...
