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

The procedure that would be performed to divert stool flow when an anastomosis is not feasible is an end colostomy. This surgical intervention involves creating a new opening in the abdominal wall, where the end of the colon is brought out through the skin to allow stool to exit the body into a colostomy bag. It effectively bypasses the affected area of the colon where an anastomosis, or reconnection of two bowel segments, cannot be performed due to factors such as significant inflammation, obstruction, or malignancy.

End colostomy is specifically indicated in situations where the distal bowel might be concerned or compromised, and maintaining fecal diversion is essential for patient care and recovery. It allows for bowel rest and protects any remaining healthy bowel segments.

In contrast, the other procedures listed serve different purposes: an end ileostomy diverts stool from the ileum (the last part of the small intestine) rather than the colon; a loop ileostomy is typically a temporary diversion that allows stool to pass through but also preserves some bowel function; and gastrojejunostomy is a procedure that bypasses the stomach to allow food to go directly from the stomach into the jejunum, rather than addressing stool diversion specifically.
