[Portable infusion pump for ambulatory cytostatic therapy in inoperable liver metastases].

Liver metastases were demonstrated in a 48-year-old man 12 years after resection of a carcinoma of the sigmoid colon (pT2, G2, N0, Mx). A computer-driven external infusion pump was implanted and regional liver perfusion instituted with 5-fluoro-uracil. After seven chemotherapy cycles, 4-7 weeks apart, the liver metastases were no longer demonstrable by ultrasound and computed tomography. During the entire course of chemotherapy the patient was able to continue his profession as a teacher without any restriction.
