First of all welcome to HW. I am sorry to read of your partner's situation.
The wall of the stomach is made up of four layers: the mucous, submucous, muscular, and peritoneal layers. The mucous and submucous layers are made up of ridges called rugae. Within the ridges are gastric glands made up of mucous cells, parietal cells, chief cells, and G-cells. Each of these cells secretes a chemical that aids in the process of digestion.
I am still not certain I understand exactly what has happened to your partner -
A gastrectomy is surgery to remove part or all of the stomach. Gastrectomy is performed for several reasons, most commonly to remove a
malignant tumor or to cure a perforated or bleeding stomach ulcer.
I would strongly encourage your partner to seek out second opinions re the situation as it stands.
Wish I could have been more help to both of you.
