Specific Diagnoses and Management Principles of the Intestines and Lower Digestive Canal

Abstract

Acute appendicitis, visceral perforations, diverticulitis (including bleeding and abscesses) acute calculous cholecystitis, acute ischemic bowel, mesenteric artery ischemia and infarction can cause acute abdominal conditions which prompt emergency interventions. Inflammatory bowel diseases (ulcerative colitis and Crohn’s disease) may be followed up in some time without remarkable complications, although at some point with abscesses, hemorrhagic diarrhea and acute abdominal syndromes. However, the differential diagnosis (DD) of patients presenting with acute abdominal pain is much broader than this, including many benign conditions as well. Some etiologies of abdominal pain such as cholangitis strangulated hernias, colonic diverticulitis, perianal/ perirectal abscesses and fistulas may progress and turn into life threatening conditions like abdominal sepsis without proper management.
