Irrigation is done with a special short cone-shaped end (called a stoma cone) to the irrigation tubing. This is designed this way in order to 1) keep the fluid being instilled from leaking out, and 2) making sure that the colon is not perforated.
Here is a link to a picture:

An enema done through a stoma with a standard enema tip could perforate the bowel, because the bowel to the stoma may be at an angle.
Is there an actual order from the MD for an enema through the stoma? If so, I would contact the WOC nurse to do it or at least give you tips.
When I have had patients with a colostomy and constipation, we either used a soft 16 french catheter and instill mineral oil through the stoma (which did not resolve the probem) or used a laxative (orally), which did resolve the problem.
Hope this helps,
