### output:

Hi, Thanks for writing in. Unfortunately your father is having stage 4 cancer esophagus with spread to bones and also around the operated area. In this case, it is difficult to provide a curative treatment option. I am not sure if there is occlusion of esophagus after surgery. If present then this can be temporarily opened by inserting a metallic bare stent. However, it is not known when it might get blocked again. It is also important to discuss the invasion of descending aorta wall by the tumor. If there is encircling of the aorta by the tumor then it is not an emergency but if the wall of descending aorta is infiltrated by the cancer esophagus then it can become an emergency if the aorta leaks. This has to be discussed with his doctor as seen from the CT scan. Your father requires good pain relief and nutrition to maintain his general condition and make him comfortable. Please do not worry.
