my mom's was localized too. only spread to one lymph node which was removed. tell your doctor to do everything he can to spare some of your stomach. if not, it's o.k. 90% of one's digestion occurs in the intestinal area, so not having a stomach only poses some inconveniences. vitamin B12 supplements for life. my mom was already taking those by injection every now and again for fatigue, so that's no big deal. laying on a bed that's about 10% raised at the head, so bile doesn't come up your esophagus in the middle of the night. when your stomach is removed, that little flap between the stomach opening and the bottom of your esophagus is gone so if something wants to come up, there's nothing to stop it except gravity.
my mom is doing great. it's just a process and learning to eat more timees a day, smaller portions.
