Hi.
Thanks for your query. Read the history about your Mother and understood it.
The cause of sudden mottling on the stomach after the drain is removed after modified Whipple's surgery can be due to following reasons:
-Commonest reason is some sort of
allergy, for which a detailed history is need.
-There might have been leakage of pancreatic enzymes, which can cause this.
-The spread of infection in the subcutaneous planes can also cause this.
If the
vomiting is persistent, if the other signs or symptoms develop like continuation of vomiting, distension of abdomen,
constipation or obstipation,
fever an so on, she needs to be admitted; Nasogastric tube passed and kept on intravenous fluids and antibiotics. Blood and urine investigations will be done.
CT scan of the abdomen will help to diagnose a few more things and the course of action will depend upon the progress of the symptoms / signs / vitals and complications if they develop.
Take care, get her admitted and do not take your Mother home till she is cured well.
