Self-expanding metal stents for the palliation of malignant gastric outlet obstruction in patients with peritoneal carcinomatosis

Figure 2 Kaplan-Meier curves of patient survival. A: The median survival was shorter in patients with PC compared to those without evidence of peritoneal disease (48 d vs 70 d). This difference was statistically not significant (P = 0.21); B: Patients showed significantly longer survival after clinical success of SEMS placement compared to those experiencing clinical failure (14.5 d vs 75 d; P = 0.0003). P-values: Log-rank test. SEMS: Self-expanding metal stents; PC: Peritoneal carcinomatosis.
