EP.FRI.614 An Atypical Case of Small Bowel Obstruction in the Virgin Abdomen: Case Presentation and Literature Review

Résumé fourni par la source

Abstract Aims The management of post-operative adhesional small bowel obstruction (SBO) has shifted from the historical motto of “the sun should never rise and set on a complete SBO” to a non operative approach in selected patients. Despite this shift, the operative management of patients with SBO with a virgin abdomen is still encouraged. Methods We present an atypical case of SBO managed conservatively with resolution, without surgical intervention. A literature review is conducted and our case compared with the current literature. A treatment algorithm is presented. Results A 57 year old with a virgin abdomen presented with vomiting and abdominal pain. Computed tomography was consistent with mid to distal SBO proximal to the terminal ileum, in the context of a high riding caecum. He was managed conservatively. Symptoms resolved within 12 hours without gastrograffin. Gastrograffin was subsequently given to ensure contrast was present in the large bowel. At 6 month follow up he remains symptom free. Discussion Many advocate surgery is the cornerstone of the management of SBO in the virgin abdomen. There is little evidence to support this. Recent emerging evidence challenges this view. Ultimately the clinical evaluation of the patient is paramount in selecting which patients can be managed conservatively. A longer interval to operation may carry greater risk of ischaemia and bowel resection. Therefore careful patient selection and serial examination is vital and one should have a low threshold for early operative intervention in the patient which isn't settling. Follow up should be tailored to each patient.
