    Abstract:
    BACKGROUND: The laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair is an evolving technique associated with the well-known advantages of a minimally invasive approach. However, general anesthesia is routinely required for the procedure. Based on our previous experience in regional anesthesia for laparoscopic procedures, we designed a pilot study to assess the feasibility and safety of performing laparoscopic TAPP repair under spinal anesthesia. METHODS: Forty-five American Society of Anesthesiologists I or II patients with a total of 50 inguinal hernias underwent TAPP repair under spinal anesthesia, using a low-pressure CO(2) pneumoperitoneum. Five patients had bilateral hernias, and 4 patients had recurrent hernias. Thirty hernias were indirect and the remaining direct. Intraoperative incidents, postoperative pain complications, and recovery in general as well as patient satisfaction at the follow-up examination were prospectively recorded. RESULTS: There was 1 conversion from spinal to general anesthesia and 2 conversions from laparoscopic to the open procedure at a median operative time of 50 minutes (range 30-130). Ten patients complained of shoulder pain during the procedure, and 6 patients suffered hypotension intraoperatively. The median pain score (visual analog scale) was 1 (0-5) at 4 hours after the completion of the procedure, 1.5 (0-6) at 8 hours, and 1.5 (0-5) at 24 hours, and the median hospital stay was 1 day (range 1-2). Sixteen patients had urinary retention requiring instant catheterization. At a median follow-up of 20 months (range 10 months-28 months), no recurrence was detected. CONCLUSIONS: TAPP repair is feasible and safe under spinal anesthesia. However, it seems to be associated with a high incidence of urinary retention. Further studies are required to validate this technique.
