Interventions/Control_1

TAP block group: after induction of standard general anesthesia, echo-guided TAP block will be performed. The anesthesiologist who performs TAP block will be different from the one who inducts and maintains general anesthesia.
During the TAP block procedure, everyone except the TAP blocker and a nurse who assists the TAP blocker will leave the operation room.
The doctor who assesses the patients' postoperative pain, symptoms, and analgesic dose will be different from the anesthesiologist who inducts and maintains general anesthesia, and the TAP blocker.

Duration of Intervention;
From October 21, 2009 to December 31, 2009.

Interventions/Control_2

Control group: Same preparation of TAP block will be proceeded (disinfection of abdominal skin, abdominal description by echography, etc.) after everyone except the TAP blocker and a nurse who assists the TAP blocker leaves the operating room.
No injection will be given to the control group patients.
The doctor who assesses the patients' postoperative pain, symptoms, and analgesic dose will be different from the anesthesiologist who inducts and maintains general anesthesia, and the TAP blocker.
