Identifying survival protective factors for chronic dialysis patients with surgically confirmed acute mesenteric ischemia

Figure 1 Kaplan–Meier plot for in-hospital survival with a surgery delay less than or not less than 4. 5 d. In patients with a surgery delay < 4.5 d, the 20-d discharge probability was 44.4%, whereas the discharge probability was 50% on day 22. For surgery delays ≥ 4.5 d, the 20-d discharge probability was 14.9%, whereas the discharge probability was 50% on day 54. Surgery delay was defined as the time from the onset of signs and symptoms of acute mesenteric ischemia to surgery.

Figure 2 Kaplan–Meier plot for in-hospital survival with bowel resection involving or not involving the colon. For resection not involving the colon, the 20-d discharge probability was 48.0%, whereas the discharge probability was 50% on day 21. For resection involving the colon, the 20-d discharge probability was 24.7%, whereas the discharge probability was 50% on day 36.

Figure 3 Kaplan–Meier plot for in-hospital survival with a total bowel resection length less than or not less than 110 cm. In patients with a total bowel resection length < 110 cm, the 20-d discharge probability was 45.8%, whereas the discharge probability was 50% on day 21. In patients with a total bowel resection length ≥ 110 cm, the 20-d discharge probability was 20.1%, whereas the discharge probability was 50% on day 40.
