Retrospective comparison of mesh and sutured repair for adult umbilical hernias.

ABSTRACT

Adult umbilical and paraumbilical hernia repair is associated with a high recurrence rate of 10-30%. Mesh repair has been reported to be associated with low recurrence rates. This study aims to compare sutured repair with prosthetic mesh repair to evaluate recurrence and infection rates. A retrospective study was conducted over an 8-year period including all the umbilical and paraumbilical hernia repairs performed by one consultant surgeon. The hernias were repaired using interrupted suture, Mayo overlap, flat mesh and mesh plug techniques. The study was based on case-note review, telephone and postal questionnaire survey. A total of 100 patients were studied, of which 70 had paraumbilical hernias, 28 had umbilical hernias and 2 had both types of hernia. Median age was 56 years (range 19-90 years). A total of 61 patients had suture repair (50 interrupted suture repair, 11 Mayo) and 39 had prosthetic mesh repair (33 mesh plug, 6 flat mesh). The median body mass index (BMI) was 31.2 (range 23.4-44.5) in the suture repair group and 33.3 (range 24.1-59.1) in the mesh group, with no significant statistical difference in BMI between the two groups (P>0.05). Median follow-up was 4.5 years (range 1-8 years). Recurrence rates for the suture and mesh repair groups were 11.5 and 0%, respectively (P=0.007). Infection rates for the suture and mesh repair groups were 11.5 and 0%, respectively (P=0.007). Our data suggest that prosthetic mesh repair is ideal for managing primary and recurrent umbilical hernias in both obese and non-obese patients.
