The expected initial output of an ileostomy postoperatively is typically loose, dark green liquid. This output occurs because the ileum, which is the last part of the small intestine, is able to absorb some nutrients and water, but it still allows for the secretion of digestive enzymes and bile, which can contribute to the dark green color. Postoperatively, the bowel is still in the process of adjusting to its new role, and because reabsorption of fluids might not be fully functional immediately, the output tends to be more liquid than formed.

As recovery progresses, the output usually becomes thicker and may shift in color and consistency as the patient begins to resume a normal diet. Initially, the presence of bile in the feces, which is the dark green component, is typical because it reflects the nature of small intestinal contents. Understanding these changes is crucial for effective patient management and monitoring post-ileostomy.
