These symptoms are associated with gastrointestinal disease on the other phase differential, especially chronic pancreatitis, especially abdominal differential, because the two had abdominal pain and weight loss, malaise. For the chronic inflammation of the pancreas as a cancer diagnosis and treatment, also has in turn cancer misdiagnosed as inflammatory, so to be combined with other examinations to identify these symptoms.
