Hello Dr. My Father in law 72 yrs old was diagnosed esophageal cancer. He had 3 chemo then surgery then 3 post op chemo. The surgery done 3 mnths back,in Chennai, consisted of distal gastrectomy with 1 anastomisis n 60 staples where the junction of the esophagus and part of the stomach is removed. The PET Scan show nodal metastasis and a dark spot is found in the lungs. For 3 months now he was getting diarrhea followed by low blood count and low potassium n sodium. He was admitted in the clinic and now he is ok recovered i could say. Till now he s had an early dumping syndrome which is not helping him to eat properly.So he s eating small meals. Now past 2 days his foot, ankles are swollen. Do youthink its the disease progression, shall we proceed with a CT scan abdomen? Thx u so much .
