Colorectal surgery is a field in medicine dealing with disorders of the rectum, anus, and colon. The field is also known as proctology, but this term is now used infrequently within medicine and is most often employed to identify practices relating to the anus and rectum in particular.[clarification needed] The word proctology is derived from the Greek words πρωκτός proktos, meaning "anus" or "hindparts", and -λογία -logia, meaning "science" or "study".

Physicians specializing in this field of medicine are called colorectal surgeons or proctologists. In the United States, to become colorectal surgeons, surgical doctors have to complete a general surgery residency as well as a colorectal surgery fellowship, upon which they are eligible to be certified in their field of expertise by the American Board of Colon and Rectal Surgery or the American Osteopathic Board of Proctology. In other countries, certification to practice proctology is given to surgeons at the end of a 2–3 year subspecialty residency by the country's board of surgery.


Scope of the specialtyEdit

Colorectal surgical disorders include:

Surgical treatment and diagnostic proceduresEdit

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.

Mechanical bowel preparationEdit

Mechanical bowel preparation (MBP) is a procedure lacking evidence in the literature,[1] wherein fecal matter is expelled from the bowel lumen prior to surgery, most commonly by using sodium phosphate.[2]

In popular cultureEdit

In the Seinfeld episode "The Fusilli Jerry", Kramer incorrectly gets the vanity plate Assman. He hypothesizes that it belongs to a proctologist because they have a great sense of humor.[3]
