Abstract
Mobile cecum syndrome is an embryological disorder defined as a loose attachment of the cecum to the retroperitoneum. Constipation is the most frequent complaint, but some cases present with bowel obstruction due to twisting or invagination of the bowels.
A 27-year-old-man was admitted to our institution with complaints of melena and constipation. He had no previous medical history. A soft elastic mass with tenderness was found in his right lower abdomen. On abdominal ultrasonography, the mass appeared as a target sign with a small amount of ascites. Abdominal enhanced CT showed highly dilated small intestine located within the transverse colon. At operation, the invagination of the bowels was returned to the normal position, but the vascular congestion of the bowels remained. There were no tumors or stenosis in the bowel. However, the highly loose attachment of the cecum and part of the terminal ileum was found at operation. The patient was diagnosed as having an invagination due to mobile cecum syndrome. There was no need for bowel resection, and fixation of the cecum to the retroperitoneum was performed. The patient's postoperative course was uncomplicated. He was discharged on the 11th day after operation and has had no recurrence after 1 year.
