Obstructive jaundice caused by lymphatic remetastasis from the hepatic metastasis of rectosigmoid cancer.
The significant benefit of performing hepatic resection for hepatic metastases from colorectal primary cancers is well established; however, the effectiveness of dissection of the lymph nodes draining the liver remains uncertain. Herein, we report the case of a 52-year-old man who was found to have obstructive jaundice caused by lymphatic remetastasis from the hepatic metastasis of primary rectosigmoid cancer. He had previously undergone a high anterior resection for the rectosigmoid cancer, in April 1990, and a hepatic resection for metastasis was done in March 1994. When the hepatic resection was carried out, dissection of the regional lymph nodes of the liver (i.e., the nodes in the hepatoduodenal ligament) was not performed because no obvious metastatic nodes were identified. Three years after the hepatic resection, enlarged lymph nodes compressing the extrahepatic bile duct from outside were identified by cholangiography and computed tomography (CT). Because radiological studies were unable to determine the lesion capable of metastasizing to these nodes, they were diagnosed as remetastasized lymph nodes from the hepatic metastasis that had been resected 3 years earlier. The lymphatic remetastases were intractable to treatment, and the patient finally died of hepatic failure and malignant cachexia. This case serves to demonstrate that lymphatic dissection of the regional lymph nodes may need to be taken into consideration when resection of hepatic metastases from colorectal cancers is performed.
