Summary:•A retrocecal hernia is a rare type of pericecal hernia.•The genesis of retrocecal hernias is explained based on the minimal error in rotation with incarceration behind the cecum.•Abdominal computed tomography scan is useful for preoperative diagnosis of retrocecal hernia. Retrocecal hernia is a rare type of pericecal hernia. Because it is difficult to diagnose preoperatively, it is often treated with emergency operation. An 83-year-old male patient experienced sudden abdominal pain. Marked small bowel dilatation and intestinal obstruction were detected by abdominal computed tomography (CT). An enhanced CT scan also revealed a trapped cluster of small bowel loops behind the cecum and ascending colon. We preoperatively diagnosed small bowel ileus as a result of retrocecal hernia. After conservative therapy with a long intestinal tube, an emergency operation was performed. During the surgery, a portion of the ileum was found to be incarcerated in the retrocecal fossa. Intestinal resection was not necessary because the incarcerated ileum appeared viable, and the orifice to the hernia was opened. The patient was discharged without postoperative complications. The diagnosis of retrocecal hernia can often be confirmed intraoperatively. This disease is identified based on a minimal error in rotation with incarceration behind the cecum during the final phase of descent and fixation of the right colon or failure of cecal and retroperitoneal fixation. Early preoperative diagnosis is important to prevent intestinal ischemia, necrosis, and perforation and to reduce resection rates. Early preoperative diagnosis is important to avoid resection of the small intestine. CT scans are useful for preoperative diagnosis in case of retrocecal hernia.
