<正>A 44-year-old man. who was diagnosed with a gastrointestinal stromal tumor incidentally during emergency laparotomy for treatment of acute obstruction of small intestine at another hospital in 1999, was referred to our hospital due to a solitary metastasis in the liver in November 2002. A right seg-mentectomy (Segment 6, Couinaud's system) of liver was carried out. Half and one years later, a recurrent metastasis with involvement of the inferior vena cava was detected in posterior region of the liver. He underwent the third surgery in May 2004. Three another small metastases in greater omentum were found and removed. The tumor in posterior sector of the liver was en bloc resected with portion of involved inferior vena cava and diaphragm. The resected vena cava is repaired primarily through a lateral venorraphy. However, local recurrence was detected one year later, he recieved the fourth surgery in July 2005. He is now in Gleevec therapy. At present, he is in good health and free of recurrence.
