Obstructions are different in adults and children because first of all children have a smaller airway meaning that some objects may cut off there breathing more easily. Also children are more likely to get objects stuck in there airways since they don’t know any better. To retrieve an object from a child’s airway you should make sure they are breathing first and then use special tools to go in the child’s throat and retrieve the object. For an adult you will do the same thing but use a different tool. If the adult is able to still breath, eat, and swallow correctly the object will most likely just pass through the system at some point but it’s best to remove it.
The most likely diagnosis would be ulcerative colitis, given the patient's history of regional enteritis and the finding of dark blood at the level of the sigmoidoscope.
