Peak incidence occurs in the second and third decades of life. We present a patient with Crohn’s disease whose first presentation was profuse bleeding/rectum following blunt abdominal trauma. PRESENTATION OF CASE: A 29 year old previously healthy man presented one hour after sustaining rela- tively mild abdominal trauma, due to fall onto the ball during a rugby match. He complained of abdominal pain and one episode of large fresh rectal bleeding. He was pale and distressed with hypotension, tachy- cardia and abdominal guarding & fresh blood on digital rectal examination. With a provisional diagnosis of intestinal injury he was taken to theatre. Right hemi-colectomy was done for a thickened and inflamed segment of distal ileum, a large adjacent mesenteric haematoma & mesenteric lymph nodes and blood in distal bowel. Histology confirmed the features of Crohn’s disease. DISCUSSION: Crohn’s disease is unusual cause of massive lower gastrointestinal bleeding occurring in 0.9–6% of patients. Rectal bleeding associated with diarrhoea is relatively more common than massive bleeding. The presence of Crohn’s disease in young patients presenting like this is unlikely to be suspected and diagnosis could only be made after laparotomy. © 2011 Surgical Associates Ltd. Elsevier Ltd.

Both ulcerative colitis and Crohn’s disease are heterogeneous in their presentation, lack internationally uniform diagnostic criteria and can be associated with long delays between symptom onset and definite diagnosis. These characteristics make the identification of the disease difficult. Ulcerative colitis and Crohn’s disease may manifest at any age, their peek incidence occurs in the second and third decades of life. We present a patient with Crohn’s disease whose first presentation was profuse per rectal bleeding following blunt abdominal trauma. 2. Presentation of case A previously healthy 29 year old man arrived via ambulance to the emergency department with per rectal bleeding one hour after sustaining relatively mild abdominal trauma, falling onto the ball during a rugby match. On arrival he complained of wors- ening abdominal pain and had one episode of large blood loss on defecation. On physical examination he was slightly pale and distressed with blood pressure of 90 mmHg systolic and heart rate of 130 beats per minute. Abdominal examination revealed voluntary guarding with scanty bowel sounds. Fresh blood was * Corresponding author. Tel.: +44 7810827770; fax: +44 1248 384661.

His systolic blood pressure initially responded to a 1.5 l intravenous crystalloid challenge, but dropped to 90 mmHg within 15 min, coinciding with further large bright red per rectal blood loss. A provisional diagnosis of intestinal injury causing massive and continued haemorrhage due to blunt abdominal trauma was made and he was taken to theatre for laparotomy with endoscopy available. At laparotomy a segment of the distal ileum was found to be thickened and inflamed with a large haematoma along the mesenteric border with multiple palpable mesenteric lymph nodes (Figs. 1 and 2). The bowel distal to this was distended with blood. No perforation was identified. The findings were consistent with Crohn’s disease with enteric bleeding due to trauma to the inflamed segment. A limited right hemi-colectomy was performed and the specimen sent for histology. Following surgery, he made a good recovery and was discharged home at day 7. He remains well at one year. The histology of the excised specimen confirmed Crohn’s disease (Figs. 1 and 2). 3. Discussion Acute gastrointestinal haemorrhage is a rare presentation of Crohn’s disease that represents a diagnostic difficulty if not accompanied with other associated symptoms. 1 Gastrointestinal haemorrhage in the setting of inflammatory bowel disease has tra- ditionally been associated with ulcerative colitis. Crohn’s disease has been described in text books as an unusual cause of massive lower gastrointestinal bleeding occurring in 0.9–6% of patients. 2–4 2210-2612/$ – see front matter © 2011 Surgical Associates Ltd.
