ABSTRACT

Objective To evaluate hernia repair with Onlay (premuscular positioning of the prosthesis) for the treatment of parastomal hernia.Methods In this study 45 patients with parastomal hernia were treated with a tension-free manner of hernia repair in situ by Onlay using prolene mesh between February 2006 and April 2012.There were 24 males and 21 female cases,including 6 recurrent parastomal hernia cases.The average age was (49 ±8) years ranging from 43 to 80.The parastomal defect ranged from 4 cm to 9 cm.Results All operations were successful.There was no hospital death or severe postoperative complications.The mean operating time was (109 ± 23) min (96-148),and the average time of pulling out the gastrointestinal decompression tube was (2.0 ± 2.0) day (12 h-3 d) and the drainage tube was removed after (5.0 ± 2.0) days (4-9 d).The mean postoperative hospitalization was (11 ± 3) days (9-16 d).42 cases achieved primary healing.The serofluid swelling in 7 cases was cured by puncturing and pressing the incision.41 cases were followed-up from 8 to 48 months,and 4 patients suffered from hernia recurrence respestively after 3 months,4 months,4.5 months and 7 months.One recurrent case was healed by conservative therapy and the other three were healed by reoperation.Conclusions Hernia repair in situ with Onlay method for parastomal hernia with prolene mesh was a safe and effective.
