Are you saying about the shape of stool like perm hair?
Any foul disorder with stool?
Stools having a unusual odour can be due to a medical condition . It needs to be evaluated. The cause can be-
Celiac disease - sprue
Infections of the large intestine
in your case, may be the pancreatitis, has caused these symptoms, as such to make a diagnose, you need to undergo stool culture test , and detailed clinical checkup.
My opinion is that you should make a appointment with doctor at earliest.
