It has been written with the intent of not rehashing what has already been discussed in literature regarding this topic, but to specifically address the question “Has anything changed?” The topics in this article range from bowel obstruction, with perforation and diffuse peritonitis, to ruptured abdominal aneurysms, to narcotic withdrawal, to hereditary Mediterranean fever. The techniques for management of the acute abdomen range from pharmacologic, to laparoscopic, to formal laparotomy.
