Purpose: The aim of this study was to compare the preperitoneal versus the preaponeurotic mesh positioning in open paraumbilical hernia repair. Methods: During the period from January 2011 until July 2012, 60 adult patients were randomly assigned to two equal groups. The patients in group A were treated by preperitoneal mesh repair and those in group B underwent preaponeurotic mesh repair. Both groups were assessed and compared. Results: There were no significant differences between the two groups in the demographics, hernia characteristics, risk factors, type of anesthesia, American Society of Anesthesiologists score or the mean follow-up period. The length of the operation was significantly shorter in group B than in group A ( P value = 0.01). There were no significant differences in the early postoperative complications except for the development of a seroma, which developed only in group B ( P value = 0. 044). The postoperative pain was significantly lower in group A than in group B ( P value = 0.01). The time of return to normal daily activities was significantly shorter in group A than in group B ( P value = 0.001). Conclusion: The preperitoneal mesh placement during the repair of paraumbilical hernias is superior to the preaponeurotic placement, because it is associated with fewer complications, less pain and a shorter time of return to normal daily activities.
