Herniation through the gastroepiploic foramen into the lesser sac is a rare cause of intestinal obstruction. The nonspecific nature of its presentation makes early diagnosis of this condition difficult. Internal herniation should be considered with a high index of suspicion in intestinal obstruction due to the high rate of morbidity and mortality associated with delayed treatment. We report the first case of caecal herniation with strangulation in the gastroepiploic foramen occurring in a postoperative patient. Decompression and reduction of the strangulated caecum was performed, followed by a right hemicolectomy. The clinical and radiological features are presented from a review of the literature on gastroepiploic foramen herniation.
