Crohn's disease (CD) is a chronic inflammatory disease and is an autoimmune disorder. Due to its remission and relapse cycle, the integrity of the intestinal wall becomes compromised in patients with inflammatory bowel disease. This increases susceptibility to bowel perforation following mechanical injury, especially in patients using immunosuppressive therapy. However, few reports discuss the severity of injury after abdominal trauma in Crohn's patients and how much mild abdominal blunt trauma in such patients can be different in the presentation clinically in correlation with the severity of the intraoperative findings. We report a case of ascending colon perforation secondary to mild abdominal blunt trauma in a patient with CD.Categories: General Surgery Keywords: post operative (po), junction between the cecum and ascending colon (jbcac), low intensity blunt trauma (libt), crohn's disease (cd), computed tomography (ct )
