LC has been shown to be feasible under spinal anesthesia if performed with proper technique. There are many reports demonstrated the effectiveness and safety of LC under spinal anesthesia in selected patients. However, patients with complicated gallstone disease such as acute, gangrenous or subacute cholecystitis have been considered as unfit cases for LC under spinal anesthesia because of technical difficulties. On the other hand, spinal anesthesia has also been regarded as inappropriate for patients complying with American society for anesthesiology (ASA) III and IV due to the uncontrolled anesthesia risks.
