Hi.
Thanks for your query.
Noted the history of blockage at duodenum, have been told that you have
gastroenteritis and ulcers, pain on right of abdomen that has progressed to the middle of back - small hard ball like poop - started in 2007 when had periods of severe diarrhea for about three weeks - the poop was small and floated.
All this history is suggestive of post-ulcer duodenal scarification. and as you have stated the problem started way back in 2007 and seems to have continued.
I would advise you the following in such a situation:
Get a repeat upper GI Endoscopy done to review the present state.
Barium study to see for the extent of blockage and decide whether you need a corrective surgery.
CT scan or MRCP to see whether there is secondary
pancreatitis or not, a known cause of
referred pain in the back.
Clinical evaluation regularly.
PPI like
Omeprazole.
Antacid and motility regulator called a
Domperidone.
Soft bland and frequent feeds.
Further treatment as per the reports.
