During operations in the lower part of the abdomen injuries to nerves located here arise in 1-4,2 per cent; the most frequently iliohypogastric, ilioinguinal, genitofemoral and lateral femoral cutaneous nerves. These injuries to nerves are often very painful and till to day very difficult to treat. Clinical terminology of their injuries is variable and not strict. Therefore we suggest an all embracing term "abdominoinguinal pain syndrome". The authors present four case reports, in whom centrocentral anastomosis with use of both autologous interposed segment of nerve and also without it, achieved successful treatment of chronic pain. On the basis of this experience the authors prefer centrocentral anastomosis without autologous interposed segment of nerve, which is technicaly more simple.
