What type of bowel condition results in lesions through all layers of the bowel?

The correct choice is Crohn's disease, as this condition is characterized by the presence of lesions that can penetrate through all layers of the bowel wall. This transfixing nature of Crohn's disease leads to complications such as fistulas, strictures, and abscesses due to the inflammatory process that affects every layer of the intestinal wall.

In contrast, ulcerative colitis primarily involves the mucosal layer of the colon and does not typically extend through the entire thickness of the bowel wall. Irritable bowel syndrome is a functional disorder and does not involve structural changes or lesions in the bowel tissue. Celiac disease is an autoimmune condition characterized by an inappropriate immune response to gluten, leading to damage primarily to the mucosal layer in the small intestine, rather than lesions through all bowel layers. Thus, the unique pathological feature of Crohn's disease makes it the correct answer for this question.
