[Hepatectomy with microwave coagulation therapy for multiple liver metastases of rectal carcinoid--a case report].
A woman in her 50s was admitted to our hospital for the evaluation of liver masses. Low density areas at S5, S6 and S8 of the liver were revealed by enhanced abdominal CT scan. While exploring for the primary site, we observed a flat tumor, 10 mm in diameter, in the rectum at 10 cm from the anal ring, and local resection of the tumor was performed transanally. It was histologically diagnosed as a rectal carcinoid. During surgery, ultrasonography revealed eight hypoechoic masses at S4, S5, S6 and S8 of the liver. We conducted a partial hepatectomy (S8, S5/6) and microwave coagulation therapy. Histologically, the masses were diagnosed as liver metastases of rectal carcinoid. As of 27 months since surgery, liver metastases control is favorable, and no local recurrence has been observed. Hepatectomy with microwave coagulation therapy is believed to be locally effective in multiple liver metastases of rectal carcinoid tumor.
