This patient probably has more than just upper gastrointestinal bleeding; it is very likely that there is also bleeding in some part of the lower gastrointestinal tract.
Moreover, the major source of bleeding is very likely in the lower gastrointestinal tract.
When Zhou Can first diagnosed the patient, he used both his Hemostasis Skill and Level 6 Pathological Diagnosis Skill to determine that the source of bleeding was in the upper gastrointestinal tract, most likely the stomach. However, further diagnosis now reveals that the patient likely has multiple sources of bleeding.
This indicates that there was a missed diagnosis in his initial assessment.
However, even with the missed diagnosis, he gained significant insight and explored the diagnostic techniques of top-level physicians.
At most, his Hemostasis Skill and pathological diagnosis level are still at a relatively low level, with a considerable gap to the true top level.
