Yellow foamy burning liquid with bits of stool. Just had galbladder surgery to remove one stone. Stomach still bloated and hurt. Still have nausea?

Can be normal postop. Occasionally after a cholecystectomy one may see bilous (yellow liquidy) stools especially after eating a fatty meal. This should improve with time. As long as there is no fever, chills or significant abdomen pains you should be fine in no time. If symptoms persist i would call your doctor for further evaluation.
