Tension-free mesh repair of adult inguinal hernias has become a standard procedure, but there have been few comparisons of the postoperative outcome after hernia repair using the Prolene Hernia System (PHS) vs. the Mesh Plug (MP) method in a large number of patients from a single institution.


We reviewed the medical records of patients to investigate the short- and long-term outcomes of the different types of hernia repair. Late symptoms were evaluated by questionnaire. A total of 1,141 repairs performed from 1999 to 2008 (PHS in 957 and MP in 184 repairs) were evaluated.


There were 93 early postoperative complications (8.2%). A subcutaneous hematoma was found more frequently after MP repair compared with after PHS repair (3.8 vs. 1.3%, P = 0.013). Seven hundred and ten patients (62.2%) could be followed up for more than 2 years. Recurrence was detected in 14 patients with PHS repair and two patients with MP repair (1.5 vs. 1.1%, P = 0.956). Wound infections occurred in three patients (0.3%) with PHS repair vs. none with MP repair (P > 0.999). Patients with PHS and MP repair showed no significant differences in the long-term wound pain.


The recurrence and wound infection rates were similar after hernia repair using the PHS and MP methods. Patients undergoing PHS repair developed fewer subcutaneous hematomas. An older age (≥65 years) was a significant independent risk factor for recurrence.
