Backgrounds
That postoperative pain control is very important for patient recovery. With growing interest in ERAS(Enhanced Recovery After Surgery) concept, postoperative pain management becomes more important. There were many studies about correlation of depressive mood and musculoskeletal pain. However, correlation between postoperative pain and depressive mood remains unclear.

Objectives
We evaluate the relationship between patient health questionnaire-2(PHQ-2) and postoperative pain.

Methods
Thirty patients scheduled for elective laparoscopic cholecystectomy with ASA grade 1 or 2 were recruited. They did the PHQ-2 under the supervision of researcher for about 1 minute on the day before surgery. In a post-anesthesia care unit(PACU) after surgery. Pantients numeric pain rating scale (NPRS) was checked. The total amount of analgesics used for two days after surgery was documented.

Results
The NPRS score in PACU was not significantly related (Pearson correlation coefficient = -0.011[p=0.954]) to the PHQ-2 score. However, in high PHQ-2 group used more postoperative analgesics (Pearson correlation coefficient = 0.782[p=0.000]).

Conclusions
There is a correlation between the PHQ-2 and postoperative analgesic use. Therefore preoperative PHQ-2 test is useful for predict postoperative analgesic requirement.
