Summary
This case highlights a rare strangulated small bowel obstruction caused by a transmesosigmoid hernia. Computed tomography is crucial for diagnosing such conditions, especially in patients without prior surgery.
Area of Science:
- Gastroenterology
- Abdominal Imaging
- Surgical Case Reports
Background:
- Small bowel obstruction (SBO) can arise from various causes, including internal hernias.
- Transmesosigmoid hernias are uncommon causes of bowel obstruction.
- Prompt diagnosis is essential to prevent complications like strangulation.
Observation:
- A rare case of strangulated closed-loop SBO due to a transmesosigmoid hernia is presented.
- The patient had no prior surgical history.
- Computed tomography (CT) revealed characteristic findings of the obstruction.
Findings:
- CT demonstrated a cluster of dilated, fluid-filled, U- and C-shaped small bowel loops.
- These loops were entrapped through a defect in the mesosigmoid, left of the sigmoid colon.
- The sigmoid colon was displaced anteriorly and medially.
Implications:
- This case underscores the diagnostic utility of CT in identifying rare causes of SBO.
- It emphasizes the importance of considering transmesosigmoid hernias in the differential diagnosis of SBO.
- CT imaging is vital for surgical planning and timely intervention in such cases.
