Intestinal obstruction typically refers to the inability of the intestinal contents to pass through the intestines and be expelled from the body normally. Common clinical manifestations include abdominal pain, bloating, vomiting, and cessation of bowel movements and passing gas. However, in some cases, such as partial intestinal obstruction or high intestinal obstruction, gas can still be expelled from the anus below the obstruction site. This means that some intestinal obstructions can still pass gas, but the ability to pass gas does not mean the patient has recovered.
