Located in the bottom part of the large intestine, sigmoid colon specializes in moving solid waste to the rectum. In this type of colostomy, the feces is usually more solid than in other colostomies. This is one of the most common types of colostomy.
In this, the colon stretches over the top of the abdomen. The feces, in this case, is generally soft because water from the feces has been absorbed only by a small part of the colon. Transverse colostomy can be further classified into three categories:
- Single-barrel – This permanent colon surgery specializes in removing the colon below the colostomy, which includes the anal opening and the rectum.
- Loop – This colostomy involves making a stoma for the feces to exit. The individual who undergoes this surgery passes gas or feces through the rectum at times. This is because the colon remains connected to the rectum.
- Double-barrel – In this colon surgery, the colon is segregated into two separate ends to create separate stomas. While one stoma allows passage for feces, the other enables the passage for mucus made by the colon. It is one of the least common colostomy.
In this type of surgery, the colon extends from one tip of the large intestine to the right side of the abdomen. As the colon only works partially, it is unable to absorb water from the feces entirely. This implies that the feces is largely liquid. An ileostomy is often more recommended for this part of the colon and, hence, this type of colostomy is rare.
This enables the colon to channelize feces down the left side of the abdomen. The feces, in this case, is usually solid.
What is Colostomy for?
Colostomy may be required for a range of medical conditions as below:
- Colon or rectal cancer
- Severe infection like inflammation of the little sacs on the colon, referred to as diverticulitis
- Colon or rectal injury
- Birth defect like blocked anal opening, known as imperforate anus in medical terms
- Inflammatory bowel disease
- Partially or completely blocked intestines
- Injuries or fistulas in the perineum. A fistula refers to abnormalities in certain internal body parts, or between an internal organ and the skin. A man’s perineum is between the scrotum and anus, while a woman’s perineum refers to the body part between the vulva and anus.
The need for this surgery determines whether you will need a permanent or temporary colostomy. Some injuries and bowel infections require temporary rest to the bowel before reattaching it. In such cases, a temporary colostomy is usually recommended.
