[Surgical treatment of inguinal hernia using a "tension-free" technique and local anesthesia. Initial experience]. / Trattamento chirurgico dell'ernia inguinale con tecnica "tension-free" in anestesia locale. Eperienza iniziale.

ABSTRACT

Between January, 1991 and December, 1993, 208 subjects with monolateral and 19 with bilateral inguinal hernia were submitted to herniorrhaphy. Thirty-four were recurrent hernias. All but one bilateral hernias were treated at the same time. Eight cases were operated in emergency condition for acute strangulated hernia. Two-hundred and ten operations were performed under local, 17 under general and 1 under spinal anesthesia. Herniorrhaphy was performed in 14 cases with the Bassini and in 38 with the Shouldice technique. In 191 instances the "tension-free" and in 3 the "plug" techniques were adopted utilizing a polypropylene mesh. Following local anesthesia 13 episodes of bradycardia with hypotension were recorded during the operation and 4 in the early postop period. There were no general complications. Two elderly patients developed urinary retention following general anesthesia. Local complications included 6 (2.4%) cases of infection and 4 (1.6%) cases of hematoma of the wound, and 5 (2.0%) cases of edema with infiltration of the cord. Percentage of follow-up at 1, 2 and 3 years was 96, 95, and 93 percent respectively. Five recurrences were recorded in 1 case following Bassini repair (7.6%), in 2 following Shouldice (5.6%), and in 2 following tension-free (1.5%). Local anesthesia has been confirmed to be well accepted by the patients, effective an safe, especially in the elderly patients with high operative risk. Similarly, the tension-free hernioplasty has been confirmed as a simple, easily reproducible technique, followed by less pain and disability as compared with other types of herniorrhaphies, and more effective mainly in the treatment of recurrent hernia.
