“…However, complete resection cannot be performed in many cases for extension of tumors [5,24,27,37], densely adherent to the luminal wall [4, 5, 7, 13-16, 19-22, 41, 42], and patients' will [27,28], or constrained medical resources. In such conditions, recurrence occurred postoperatively [4,9,10,12,15,21,22,24], lethal complications such as uncontrolled hemorrhage [20,42], heart failure, and sudden death happened [3,7]. The complete resection rate was significantly lower in patients with firm/extensive adhesion than that in those with no/slight adhesion of IVC or above (Table 2).…”
