Rare case report of intestinal obstruction due to incarcerated small bowel in omental breach

Abstract

Introduction and importance: Intestinal obstruction without a past surgical history of abdominal surgeries or trauma is a rare and challenging clinical situation. This case report describes the presentation, diagnosis, and management of intestinal obstruction in a patient with an uncommon aetiology of small bowel obstruction.

Case presentation: A 62-year-old female with a past medical history of hypertension, diabetes, and atrial fibrillation presented to the Emergency Department with symptoms of vomiting and abdominal distension for two days. The absence of similar prior episodes and lack of surgical or trauma history were notable. Physical examination revealed a mildly distended, tympanic abdomen. Radiographic X-ray and CT imaging identified dilated small bowel loops due to a mechanical small bowel obstruction without any evident aetiology. Surgical intervention involved the release of the incarcerated bowel loops and repair of the omental breach causing the small bowel obstruction, leading to a smooth postoperative recovery.

Discussion: This case of intestinal obstruction, caused by an incarcerated bowel through an omental breach in a patient with no history of abdominal surgery or trauma, underscores the diagnostic challenges in atypical presentations. The critical role of imaging, specifically abdominal X-ray and CT scan, was key in identifying the rare obstruction cause. The successful surgical release and repair of the incarcerated bowel highlight the need for tailored surgical approaches. This report emphasizes the importance of considering uncommon etiologies and demonstrates the complexities involved in the diagnosis and treatment of gastrointestinal conditions, advocating for a multidisciplinary approach.

Conclusions: The importance of considering rare etiologies in patients with abdominal pain, especially those lacking a typical history, is emphasized. The effective use of imaging and tailored surgical approach was key to the successful outcome. This report adds to the limited literature on omental breaches causing intestinal obstruction and underlines the necessity of a multidisciplinary approach in such cases.
