Cost analysis of incisional hernia repair by suture or mesh.

The objective was to make a cost analysis of incisional hernia repair by suture repair or prosthetic mesh repair. The study included 44 patients who underwent hernia repair between 1991 and 2000. The rate of recurrent incisional hernia after more than 1 year with associated costs was registered. In 1996, the technique of incisional hernia repair was changed from suture repair to mesh repair. With a mesh repair, zero out of 19 patients presented with a recurrence at follow-up, and with suture repair, five out of 13 had a recurrence (P<0.01). The duration of anaesthetic and operation was longer, but stay in the surgical ward, and sick leave was shorter for patients with a mesh repair than for those with a suture repair. For working patients, costs in the operating theatre were 4,095 Swedish kronor (SEK) higher with a mesh repair, and the costs for surgical ward, sick leave, and examination were 10,129 SEK lower than with a suture repair. Thus, with a mesh repair, the total costs were 6,034 SEK lower than with a suture repair. For retired patients, the total costs with a mesh repair were 1,898 SEK lower than with a suture repair. We conclude that in this setting, mesh repair of incisional hernias produced lower costs than suture repair.
