* Scar tissue: Scar tissue can form after surgery and can narrow the intestines, making it difficult for stool to pass through.
* Adhesions: Adhesions are bands of scar tissue that can form between the intestines and other organs. These adhesions can also narrow the intestines and cause a blockage.
* Hernias: Hernias are weak spots in the abdominal wall that can allow the intestines to protrude through. This can also lead to a blockage.
APO can cause a number of symptoms, including:
* Abdominal pain
* Nausea
* Vomiting
* Constipation
* Diarrhea
* Bloating
* Gas
If you experience any of these symptoms after surgery, it is important to see your doctor right away. APO can be a serious complication that can lead to further health problems if it is not treated promptly.
