EP.FRI.452 Complicated Littre Hernias

Background Meckel’s diverticulum is the most prevalent congenital anomaly of the gastrointestinal tract with an estimated prevalence ranging from 2% to 4%. The diverticulum is a remnant of the vitelline duct, which leads to the formation of a true diverticulum containing all the layers of the small intestine. The condition is usually clinically silent; however, it can present with unusual symptoms and signs and therefore can result in a delayed diagnosis, particularly in adults. The aim of this study is to review the most recent literature reporting Littre hernias in adults, the diagnostic approach and its subsequent management. This is a literature review, complemented by unusual clinical case of an adult patient who presented with a Littre hernia containing a Meckel’s diverticulum in a strangulated umbilical hernia sac, which required emergency surgery. Method Literature review using Web of science, PubMed and other reliable sources using the possible combinations of the following key words: Meckel’s diverticulum, Littre hernia, umbilical hernia, adults, complications, surgical treatment. Results The herniation of a Meckel’s diverticulum through a potential opening in the abdominal wall is defined as a Littre hernia, representing a rare complication of the diverticula. Due to their rarity, they often remain underdiagnosed, potentially leading to sub-optimal treatment and significant morbidity. Conclusion A Meckel’s diverticulum, despite being a rare clinical entity in adults, can theoretically be found in any hernia, with patients experiencing a wide range of potential complications.
