sounds like your uncle is still on zantac ...and for several years...
perhaps it should be considered that it is not working for him, since the situation has worsened.
Now he has Esophageal ulcers. and perhaps it is the zantac that has led to this... seems to me that getting off the drug(s) and treating it another way would change this.
usually people rely on the ama doctors because they really do not want to take on the responsibility of taking care of themselves... that they do not want to make the life style changes that are needed to allow the body to really heal.
iodine supplementation could probably provide some help, but if he continues to take zantac and not make the real changes that he probably knows he should make, then the situation will probably not change much. otherwise, taking iodine, he will also probably go through a bit of detox and have symptoms from this. there could be a bit of an internal tug-of-war going on with the
Iodine pulling out whatever the drug(s) may are putting in . dunno exactly how this would sit with him...
it is important to remember that no one can help anybody else. one can only help himself...
as it appears from your writing that you are hoping to help him, and maybe he is also hoping you can help him, its hard, because, no doubt, you care for him very much, and you would like to do something for him, but as long as he is not willing to help himself then he just will probably keep being sick... otherwise, he would be here asking the question for himself...
some info that i pulled off the internet follows:
Depending on their location, peptic ulcers have different names:
Gastric ulcer: This is a peptic ulcer that occurs in your stomach.
Duodenal ulcer: This type of peptic ulcer develops in the first part of the small intestine (duodenum).
Esophageal ulcer: An esophageal ulcer is usually located in the lower section of your esophagus. It's often associated with chronic gastroesophageal reflux disease (GERD).
"...doctors now know that the cause of most ulcers is the corkscrew-shaped bacterium Helicobacter pylori (H. pylori)."

"Most persons exhibit impaired production of stomach acid as they age. This impaired capability to produce adequate stomach acid may be a result of
Iodine deficiency as
Iodine promotes stomach acidity."

"H. Pylori may be inhibited by raising stomach acid or lowering its pH, provided this is done before much damage is done by the bug. This is the reason why people who manage to maintain normal stomach acid levels are generally asymptomatic and don't get ulcers unless they are taking specific drugs, they consume excessive amounts of alcohol (although alcohol itself inhibits Helicobacter Pylori), or they supplement too much calcium and magnesium, which in turn can lower stomach acid levels too
much. Coffee consumption is another factor known to aggravate the symptoms of H. Pylori infections.
Unfortunately, people with reduced acid levels frequently suffer from what they assume is elevated stomach acid (heartburn, bloating, nausea, frequent burping), and as a result often take acid-lowering drugs or remedies. By doing so, they encourage greater H. Pylori activity and thus increase the risk to develop peptic or duodenal ulcers, pancreatic / gastric cancer, and mucosa-associated lymphoid tissue (MALT) lymphoma.
H. Pylori infections can also lead to some forms of
Arthritis (calcification, spurs), iron-deficiency anemia, and Vitamin B12 deficiency that may develop as a result of lowered stomach acid levels and damage to parietal cells which produce the intrinsic factor. H. Pylori is further implicated with heart disease / arteriosclerosis, atrial fibrillation, asthma, rosacea, gum disease, and chronic headaches or migraines."
