Colorectal pertains to the colon and rectum. The colon and rectum, along with the cecum and anal canal, make up the human body’s large intestine. A colon contains four sections — ascending, transverse, descending and sigmoid.
Colon and Rectal Resection for Benign and Malignant Disease
A colon and rectal resection is the partial removal of the colon and rectum.
Benign diseases are usually easier to treat, and there’s normally a good prognosis with one of these diseases. With cancer, benign tumors aren’t cancerous.
On the other hand, a malignant disease has the tendency to become increasingly worse and can even result in death. Malignant tumors have the capability to invade into adjacent tissues and spread to distant tissues.
Surgical Treatment of Anal Diseases
We do surgical treatments for anal diseases, most notably abscess, fistula and hemorrhoids.
An abscess is an infected, pus-filled cavity near the anus. It’s a defensive reaction to help stop the spread of infectious materials to other body parts.
An abnormal connection between the epithelialized surface of the anal canal and perianal skin is an anal fistula. Anal fistulae come from the body’s anal glands, and if the outlet of these glands develops a blockage, an abscess can form.
Hemorrhoids are vascular structures in the anal canal that help with a person’s stool control. When swollen, they become pathological or piles. The two types are internal and external.
Internal hemorrhoids typically result in painless, bright red rectal bleeding and itchiness. If thrombosed or necrotic, they become painful. External hemorrhoids that are not thrombosed can produce few problems. When they are thrombosed, however, they can be very painful, but pain normally resolves within a few days. Swelling in the area of the anus is quite common with hemorrhoids.
