Ans:C. Loop Colostomy.
A loop colostomy has been created to de-function or divert the large bowel (loop colostomies use a key/bridge to hold it in position on the abdominal wall, unlike an end colostomy). They can also be used in elective surgery.
The reason for this procedure in this case would be Colonic obstruction. Apart from the abdominal distension, he would be constipated and have a tender abdomen.
COLOSTOMY
- A colostomy is a surgical procedure in which an opening (stoma) is formed by drawing the healthy end of the large intestine or colon through an incision in the anterior abdominal wall and suturing it into place. This opening, in conjunction with the attached stoma appliance, provides an alternative channel for feces to leave the body
- Types of colostomy:
- Loop colostomy: This type of colostomy is usually used in emergencies and is a temporary and large stoma. A loop of the bowel is pulled out onto the abdomen and held in place with an external device. The bowel is then sutured to the abdomen and two openings are created in the one stoma: one for stool and the other for mucus.
- End colostomy: A stoma is created from one end of the bowel. The other portion of the bowel is either removed or sewn shut (Hartmann’s procedure).
- Double barrel colostomy: The bowel is severed and both ends are brought out onto the abdomen. Only the proximal stoma is functioning.
