Comparison of safety, efficacy, and long-term follow-up between “one-step” and “step-up” approaches for infected pancreatic necrosis

Figure 4 The comparison of overall survival between “One-step” approach and “Step-up” approach. A: The mean follow-up time was 69.17 ± 2.53 mo (95%CI: 64.02-74.16). There are 31 patients died, 24 patients lost to follow-up and 103 patients survived, respectively; B: There are 12 patients died in “One-step” approach. Among them, 8 patients died during the hospitalization and 4 patients died in follow-up period, respectively. In addition, there are 19 patients died in “Step-up” approach, among them, 12 patients died during the hospitalization and 7 patients died in follow-up period, respectively. The rate of overall survival between “One-step” and “Step-up” was 10% and 11.1%, respectively (P = 0.875).
