[Tension-free hernioplasty in the treatment of inguinal hernia in the adult: our experience with local anesthesia and a review of the literature].

BACKGROUND: In the last years the real innovation in the treatment of groin hernia is represented by tension-free hernioplasty under local anaesthesia, based on the techniques of Lichtenstein and Trabucco, which use synthetic prosthesis (polypropylene) to restore the floor of inguinal tract and enable an early deambulation and return to work.
METHODS: In 21 months the authors have treated, only under local anaesthesia, 100 patients, 95 men and 5 women; the age ranged from 18 to 82 years; some of them suffer from systemic pathology (7 patients with cardiovascular diseases, 1 with epilepsy, 3 with pulmonary diseases, 1 with liver cirrhosis). All patients underwent short-term antibiotic prophylaxis. No mortality was recorded. The mean follow-up was 12.5 months with only one little and low recurrence detected.
RESULTS: Good results were obtained also in terms of intraoperative complication (nausea, vomiting, bradycardia, pain) and post-operative complications, (ecchymosis of scrotum and penis, edema of the scrotum, swelling of the skin suture, subcutaneous hematoma, inguinal pain, fever), not life-threatening, well tolerated and resolved spontaneously.
CONCLUSIONS: The authors stress the advantages of local anaesthesia, the economic spare due, to one day hospital stay, the safety of the technique also in patients with severe general diseases (0.9-1% in USA). The authors survey the international literature confirming the great effectiveness of tension-free inguinal hernioplasty, in particular in terms of recurrences (Trabucco 0-0.025%, Amid 0.1%).
