Colonic trauma and Colostomy
A young man was brought in after he came off his motorcycle. He was conscious and breathing well but in shock (very low blood pressure) and pale. A quick examination reveals that he has a guarded abdomen (this means that the abdominal muscles are tensed up and indicates that there is some irrritant in the abdominal cavity, in this patient, probably blood.) He also had broken both femora (thigh bones). These injuries could kill if not attended to speedily.
After initial resuscitation, he was taken to operating theatre and a laparotomy (surgery on the abdominal cavity) was performed. He was found to have a ruptured colon. It had spilled its contents (faeces) into the abdominal cavity, soiling it. “Dilution is the solution to pollution”, my mentor used to say. The abdominal cavity was washed out with plenty of warmed fluid.
There was a large hole in the colon, so direct repair was not safe. There were 2 alternatives: 1. resect the affected portion of the colon and anastomose (re-join the colon); or 2. bring the perforation out to the skin as a stoma.

Since he was unstable, the stoma was a rapid and safer option. A “stoma” means an “opening or mouth”. A “colostomy” is an opening from the colon to the skin. This was done to divert the bowel spillage externally and allow the contamination in the abdomen to resolve.
This particular colostomy is a “loop” colostomy. It means that a portion of the colon is brought out and opened without disconnecting the two ends. After a period of a few weeks, when the abdominal inflammation has resolved, the loop of colon will be released from the skin, closed and returned to it’s normal location in the abdomen.
