[Digestive perforations and occlusions]

Acute abdominal disorders are common reasons for consultation at the emergency department. The diagnosis of all acute abdominal disorders begins with a careful history and physical examination. When appropriate, the clinical examination should be supplemented by conventional plain abdominal radiography. Gastrointestinal perforation and obstruction are very commonly encountered in the diagnosis of acute abdomen. Plain abdominal radiographs are the initial diagnostic methods of choice. In some circumstances, ultrasonography and CT may be valuable for the evaluation of the cause of abdominal disorder.
