Large bowel obstruction secondary to a cecal bascule with internal herniation through the foramen of Winslow: A case report.

Introduction: Internal hernias are a rare phenomenon, and even rarer is a herniation through the foramen of Winslow. The clinical presentation of patients with an internal hernia is often vague and difficult to diagnose clinically. If internal hernias go undiagnosed and untreated, patients can develop bowel compromise leading to a high morbidity and potential mortality. Radiologic imaging is helpful in bringing the diagnosis to the forefront of the clinicians mind, but the diagnosis is often made intra-operatively.

Presentation Of Case: An eighty-one year old female presenting with a few months of vague abdominal symptoms who was found to have a cecal bascule internally herniating through the foramen of Winslow was treated successfully with surgical intervention.

Discussion: Internal hernias occur when there is a protrusion of a viscera through the peritoneum or mesentery and confined within the abdominal cavity. Internal hernias are classified according to location and vary from paraduodenal, transmesenteric, and pelvic to name a few. Hernias through the foramen of Winslow are a rare subset, and were the internal hernia found in our patient intra-operatively. Our patient's clinical presentation was vague with generic abdominal complaints and radiologic imaging was inconclusive for a definitive diagnosis. However, prompt surgical intervention resulted in a good outcome for our patient.

Conclusion: Internal hernias, to be diagnosed and treated promptly, require a high index of suspicion from a clinician based on clinical presentation and radiologic imaging. These patients belong in the operating room, and interventions are directed based on the anatomical findings intra-operatively.
