Preoperative colonic stents vs emergency surgery for acute left-sided malignant colonic obstruction: Meta-analysis with systematic review of the literature

Figure 1 PRISMA 2009 flow diagram.

Figure 2 Mortality rate. No statistically significant difference was found between the colic stenting and emergency surgery groups.

Figure 3 Morbidity rate. No statistically significant difference was found between the colon stenting and emergency surgery groups.

Figure 4 Permanent stoma rate. No significant difference was found between the colon stenting and emergency surgery groups.

Figure 5 Primary anastomosis rate. Tthis parameter is higher in the colonic stenting group, with a significant difference in comparison with the emergency surgery group.

Figure 6 Stoma creation rate. Tthis parameter is higher in the emergency surgery group, with a significant difference between the two groups considered.

Figure 7 One-year recurrence rate. This parameter is higher in the colonic stenting in comparison with the emergency surgery group, with a significant difference between the two groups.

Figure 8 Disease-free survival rate. No significant difference was found between the colonic stenting and emergency surgery groups.

Figure 9 Overall survival rate. No significant difference was found between the colonic stenting and emergency surgery groups.
