If you have experience with this, would you email me? The most common cause of splenomegaly is chronic inflammation of the GI tract, usually Helicobacter mustelae. While I wouldn't want to make any definitive diagnoses here, you very well may have treated one of the symptoms, but missed the primary problem. The fact that he has actually gained weight makes it a bit more likely that he has gastric helicobacter than inflammatory disease of the intestine. I wouldn't want to rule out a gastric foreign body at this point, either. Possibilities here would be to try a course of antibacterial therapy for Helicobacter, or do an abdominal exploratory with biopsy of the stomach and intestine. Chronic vomiting is not a problem that you should ignore - its is generally a symptom of a disease that needs to be closely examined.
