Synthetic vs biologic mesh for the repair and prevention of parastomal hernia

Table 4 Summary of pooled proportions of outcome measures of biologic mesh repair vs synthetic mesh repair

Hernia repair	No of studies	No of mesh repairs	Recurrence	Complications
				Wound infection	Mesh infection	Other
Biologic mesh	5	84	24% (8.6-44.1)	5.6% (1.4-12.1)	0% (0-5.4) FE	13.4% (1.9-32.7)
Synthetic mesh	21	669	15.1% (9.7-21.6)	2.8% (1.6-4.4)	3.1% (1.8-4.6) FE	17.8% (12.0-24.4)
P value			0.01	0.32	0.39	0.15

Two-tailed Fisher’s exact test was used because of too small frequencies. FE: Fixed-effect model.
