Thank you for the query.
A part of diverticulitis
surgery is intestinal junction creation. Such junction in some cases can be more narrow than regular large intestine. This narrow junction can impede stool passage or even give bowels obstruction. That is why, it is very important to watch for stool obstruction symptoms and visit a doctor to make sure its not an obstruction.
I suggest you to visit your surgeon and do not wait anymore. Abdominal X-ray
should be done and colonoscopy
Hope this will help.
