Which procedure would likely be performed to divert stool flow when an anastomosis is not feasible?

The procedure that would most likely be performed to divert stool flow when an anastomosis is not feasible is an end colostomy. This procedure involves creating an opening of the colon (the large intestine) to the abdominal wall, allowing stool to exit into an external bag. It is particularly indicated in cases where there is a significant obstruction, disease, or injury in the lower gastrointestinal tract that prevents the formation of a direct connection between two healthy segments of the bowel through an anastomosis.

End colostomy helps bypass the segment of the bowel that is diseased or compromised, ensuring that stool can be eliminated from the body without passing through the damaged area. This procedure provides a means of temporary or permanent stool diversion depending on the underlying condition.

The end ileostomy, while a similar concept, is utilized for diverting stool flow from the ileum, which is the last part of the small intestine, and is typically performed when the colon is not functional or needs total diversion. A loop ileostomy creates a temporary diversion of the small intestine but is often reversible. On the other hand, gastrojejunostomy is a procedure that connects the stomach to the jejunum (part of the small intestine) and is not relevant to
