Perhaps I should wait until I see my surgeon in September but wonder if anyone can tell me.
I haven't had an oesophagectomy but had a Collis-Nissen fundoplication (repair) a few months ago.
The Collis procedure effectively extends the length of the oesophagus by using a wedge section of the stomach - in much the same way as the stomach is used to form the oesophagus in an Ivor Lewis.
The stomach is lined with parietal cells that produce acid. So I guess following an Ivor Lewis or a Collis, there are then acid producing cells actually within the oesophagus?
