Background: Mesh repair of umbilical hernia has been associated with a reduced recurrence rate compared with suture closure, but potentially at the expense of increased postoperative complications and chronic pain. The objective of this systematic review and meta-analysis was to examine the outcomes after elective open mesh and suture repair for umbilical hernia in adults.
Methods: A literature search was conducted to identify studies presenting original data on elective open mesh and suture repair of umbilical hernia. The primary outcome was hernia recurrence. Secondary outcomes included surgical-site infection (SSI), seroma, haematoma and chronic pain. Meta-analyses were undertaken. Results: The search resulted in 5353 hits and led to 14 studies being included (6 RCTs and 8 observational studies) describing a total of 2361 patients. Compared with suture, mesh repair was associated with a lower risk of recurrence (risk ratio (RR) 0⋅48, 95 per cent c.i. 0⋅30 to 0⋅77), with number needed to treat 19 (95 per cent c.i. 14 to 31). Mesh repair was associated with a higher risk of seroma (RR 2⋅37, 1⋅45 to 3⋅87), with number needed to harm 30 (17 to 86). There was no significant difference in the risk of SSI, haematoma or chronic pain.
Conclusion:The use of mesh in elective repair of umbilical hernia reduced the risk of recurrence compared with suture closure without altering the risk of chronic pain.
