[A Case of Rectal Carcinoid with Liver and Lymph Node Metastases Treated by a Two-Stage Operation]

A 77-year-old woman was admitted to our hospital with the chief complaint of chest pain. CT showed a liver tumor that was 45 mm in diameter. A colonoscopic examination revealed a submucosal tumor in the lower rectum, which was diagnosed by histopathology as a neuroendocrine tumor (NET), grade 2. Liver biopsy confirmed the diagnosis of a liver metastasis from a rectal carcinoid. Considering surgical stress and possible complications, we first performed hepatectomy followed by low anterior rectal resection in a two-stage operation. Histopathological examination revealed that the rectal carcinoid was 14 mm in diameter with four lymph node metastases. After surgery, treatment with an octreotide LAR was initiated. The patient remained disease-free for 1 year 8 months after surgery.
