[The use of Dacron prostheses in laparoceles].

Background: Purpose of the study was to evaluate indications and efficacy of Dacron prostheses in the treatment of incisional hernias.

Methods: The study has been carried out in a retrospective way; mean follow-up has been 20 months. Surgical setting has been the Institute of Emergency Surgery at the University of Catania, where about 500 abdominal operations are performed every year. Thirty patients affected by incisional hernias have been considered (mean age 66.8 years). In 12 patients the Mayo technique was performed, whereas a Dacron prosthesis was placed in 18 patients. Other than early postoperative complications, patients have been followed by periodical clinical exams in order to find out possible recurrences as well as other late complications.

Results: Among 18 patients treated with insertion of Dacron prosthesis no infection, recurrence, bowel fistula, haematoma or dislocation have been observed. Only in one case an intestinal occlusion secondary to adhesions between prosthesis and bowel has occurred; in this patient a new operation has been necessary to remove the prosthesis.

Conclusions: Considering that prostheses have been used in large incisional hernias or in patients with a weak abdominal wall, the high successful percentage (94%) obtained suggests the use of Dacron prostheses which guarantee long stability and minimum risk of recurrences.
