Abstract
A 55-year-old man was admitted to our hospital with a history of recurrent bowel obstruction. Imaging examinations, including PET-CT, failed to reveal any evidence of malignancy, and laparoscopic surgery was performed to identify and treat the cause of the obstruction. During the operation, we detected a tumor-like protuberance from the ileum, approximately 50 cm proximal to the ileocecal junction, and peritoneal nodules. Partial resection of the ileum and excisional biopsy of the peritoneal nodules were performed under a presumed diagnosis of carcinoma of Meckel's diverticulum and peritoneal metastases. Histopathological examination of the resected ileum and peritoneal nodules revealed well-to moderately differentiated adenocarcinoma, but no ectopic tissue. Postoperatively, the patient failed to respond satisfactorily to chemotherapy, and eventually died of peritonitis carcinomatosa at 16 months after the surgery. The prognosis of carcinoma of Meckel's diverticulum is poor, as the diagnosis is often made only at an advanced stage due to the diagnostic limitations of imaging studies for this cancer. We report a case of Carcinoma of Meckel's diverticulum with a review of literature.
