Proctology: The practice of Proctology consists of the treatment of diseases and conditions originating within or affecting the anus, rectum, perianal and perirectal areas, and related or complicating conditions, including colonoscopy procedures. The scope of anal-rectal diseases treated medically or with minor-surgery usually include hemorrhoids, prolapse, fissures, abscess, fistula, warts, and pilonidal cyst. Proctology is a shortage specialty, and there is not a Board Certified Proctologist in most cities.

Proctologists are Board Certified by the AOBPR. A Proctologist is "more specialized" than a Colon & Rectal Surgeon. Whereas the Proctologist spends 95% of his or her time treating anal and rectal diseases - the Colon & Rectal Surgeon (below) spends most of his or her time treating colon diseases, and performing major-surgery, such as removing colorectal cancer and other tumors through small incisions in the abdomen. Some tools of the Proctologist are pictured below:

Pilonidal Cyst is a chronic infection of the skin commonly in the upper cleft between the buttocks. Typically occurring in young adults, this condition results from inverted hairs growing under skin, causing a tender abscess or a sinus draining pus. An acute abscess is managed with an incision and drained to release the pus, thereby reducing pain and inflammation. A chronic sinus usually will need to be excised or surgically opened, and packed with gauze for several weeks.

​​Colon and Rectal Surgeons are certified by the ABCRS. A colorectal surgeon is well-versed in the treatment of both benign and malignant diseases of the colon, rectum and anus and are able to perform routine screening examinations and surgically treat conditions if indicated to do so. Laparoscopic surgery is a specialized technique used to perform colon surgery through small incisions in the abdomen.  Colon and rectal diseases comprise a broad range of conditions and ailments, the severity of which can vary from mildly irritating to life threatening.

Fistula & Abscess: Anal fistulas are generally common among those who have had an anal abscess. Treatment is usually necessary to reduce the chances of infection in an anal fistula, as well to alleviate symptoms. An anal fistula is defined as a small tunnel with an internal opening in the anal canal and an external opening in the skin near the anus. Anal fistulas form when an anal abscess, that's drained, doesn't heal completely.

Fissure: An anal fissure is a linear tear in the anal skin. It is usually, but not always, caused by the passage of a hard, dry bowel movement through a tight anal sphincter. Fissures typically cause pain and bleeding with bowel movements. Treatment is usually necessary to prevent infection, abscess, or pruritus-ani (also known as anusitis or an “itchy anus”). Treatment can be with topical creamlaser fissurectomy which is less painful, controlled-intermittent anal dilatation, or with surgery (e.g. lateral internal sphincterotomy and or anoplasty).
