title: [Diagnostics and therapy of chronic pain following hernia operation].
abstract: The frequency of chronic pain after hernia repair is currently much higher than the recurrence rate. For inguinal hernias it has been shown that mesh-based techniques are comparable to mesh-free techniques concerning chronic pain. Risk factors could be clearly identified for inguinal hernia repair and include open repair, meshes with small pores, mesh fixation with sutures or tacks, pre-existing pain and severe pain during the early postoperative period. The last two risk factors are also important for incisional hernias. For laparoscopic incisional hernia repair, the width (> 10 cm) of the gap seems to correlate with chronic pain. The diagnostic measures are restricted to the identification of a segmental problem in terms of nerve entrapment which can be blocked by local anesthesia or definite neurectomy. In some cases of chronic pain after inguinal hernia repair removal of the mesh will be advisable. After incisional hernia repair a segmental involvement is rarely seen. Localized pain may be induced by stay sutures which can be removed. Mesh removal is, however, a complex procedure especially after open repair resulting in hernia recurrence and therefore represents a salvage technique. The prophylaxis of chronic pain is therefore of utmost importance as is the identification of patients at risk which is now possible. These patients for example with inguinal hernias should be treated laparoscopically with an adequate technique including meshes with big pores and without fixation or fixation with glue only.
