Long-term overall cumulative survival of the entire patient cohort with 30-day, 1-, 3- and 6-year survival of 93.7, 91.8, 90.4 and 89.1 %, respectively (left upper graph); significantly better outcomes when operated electively (p < 0.001, right upper graph); no differences between ICC and IWC groups both in elective (p = 0.857, left lower graph) and emergent (p = 0.741, right lower graph) subgroups
