Abstract
A 65-year-old male presented to the emergency department complaining of 48 hours of severe epigastric pain and guarding on physical exam. A non-contrast CT revealed a retrocardiac lipomatous mass. Chest MRI revealed an intrathoracic omental hernia through the esophageal hiatus. Intraoperatively, strangulated omentum was seen; specifically, the greater omentum herniated through the defect into the esophageal hiatus. The hiatal hernia was then successfully repaired via a robotically assisted, laparoscopic approach, and an omentectomy was performed.
