    Notes: Abstract Laser surface alloying by the powder feed method of the iron based superalloy Incoloy 800H with aluminium has been carried out. The effects of different preparation parameters, like laser scan speed and powder feed rate, on the morphology of the alloyed zone have been investigated. Microstructure and composition have been determined by scanning electron microscopy (SEM), optical microscopy, and x-ray fluorescence spectroscopy. Three different phases with different Al-content have been distinguished. The observed Al-enrichment at the surface, the presence of Ni-Al and Fe-Al intermetallic compounds, and the considerable grain refining of the alloyed zone with respect to the substrate, make this surface modification technique a very good method to improve the corrosion behaviour of the Incoloy 800H super-alloy.

    The Rives operation for the repair of incisional hernias (1997)
    Springer

    Notes: Summary 63 medium and large incisional hernias were repaired by the Rives method. A multifilament polypropylene mesh was used in all cases. The mesh was fixed to the abdominal aponeurosis with interrupted non-absorbable polypropylene stitches. There was no mortality. The recurrence rate was 1,5% (1 patient) after a median follow-up of 30 months although a high incidence of postoperative pain (17%) in the Spiegelian area was found during the first year. Based on these results we propose this technique for the repair of incisional hernias perhaps also with the use of long-lasting absorbable sutures or a biological glue. These procedures enhance attachment of the mesh to the abdominal wall and thus relieve pain in the lateral abdominal region.

    Incisional hernia following appendectomy. Surgical experience (1998)
    Springer
    Hernia 2 (1998), S. 169-171 
    Details
    ISSN: 1248-9204
    Keywords: Incisional hernia ; Appendectomy ; Mesh repair

    Topics: Medicine
    Notes: Summary Appendectomy is a very frequent cause of incisional hernia. In this paper the rate of recurrence after the hernia repair by simple suture and mesh repair was studied. 17 lateral incisional hernias secondary to appendectomy were repaired over a 9 year period. Prosthetic repair was carried out in 9 cases and primary closure in the remaining 8 cases. All the patients were followed over a period that ranged from 1 to 8 years (mean 5.6 years). There was one recurrence, though 2 patients (11.7%) with mesh repair complained about abdominal pain during the first postoperative year. The study concludes that both techniques can be successfully implemented if the correct indications based on the extent of the defect and the clinical characteristics of the patient are respected.
