[|AI|]  Thanks for your question on Chat Doctor. Esophageal cancer is very difficult to treat and when it spread to lung, liver etc. than the life expectancy is less than 1 year. Hiccup in these patients suggest aspiration into trachea. Due to mass in esophagus and abnormality in peristalsis, food often not travel smoothly on lumen and this causes persistent irritation to larynx and causes cough and hiccups. So better to put nasogastric tube to prevent all these. This tube prevent aspiration and irritation in larynx this minimizes hiccups and coughing.
