Laparoscopic cholecystectomy under spinal anesthesia: a pilot study

Abstract

Background: Regional anesthesia has not been used as the sole anesthetic procedure other than in the scenario of a patient at high risk to undergo laparoscopic cholecystectomy with CO2 pneumoperitoneum under general anesthesia.

Methods: Fifteen ASA grade I or II patients underwent laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum under spinal anesthesia. Intraoperative parameters, postoperative pain and recovery in general, as well as patient satisfaction at follow-up were prospectively recorded in a pilot study to assess the feasibility and safety of the procedure.

Results: All operations were completed laparoscopically and conversion from spinal to general anesthesia was not required in any of the cases. Median pain score 4 h postoperatively was 1.5 (range, 0-5), at 8 h it was 1 (range, 0-6), and at 24 h it was 1 (range, 0-4). All patients were discharged after 24 h. Follow-up 2 weeks postoperatively showed all but one patient to be satisfied and strongly recommending the anesthetic procedure.

Conclusion: Laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum can be successfully and safely performed under spinal anesthesia. Furthermore, it seems that spinal anesthesia is associated with minimal postoperative pain and at least an equally good recovery as with general anesthesia.
