However, because this disease is relatively concealed and the diagnosis is extremely difficult, the above tests alone are still insufficient for a definitive diagnosis.
Currently, the issue is basically pinpointed to the small intestine.
Moreover, the results of the second auxiliary examination basically confirm malabsorption in the small intestine.
To achieve a final diagnosis of this disease, at least a few more tests are needed, including even a pathological biopsy of the affected intestinal segment's mucosa.
"Dr. Li, from the current examination results of the patient, it's already certain that there are lesions in multiple segments of the small intestine. The type of diarrhea can also be determined. However, considering the patient's long course of illness, I think it is very necessary to conduct some additional tests. For example, a fecal fat absorption test and a carbohydrate absorption test can determine the type and depth of the lesion."
