The patient population in this study for the visual analog scale measurement, standard gamble questionnaire, and time trade-off questionnaire will be candidates of either sex, 18 years old or above, who have symptomatic cholelithiasis and wish to undergo laparoscopic cholecystectomy for treatment. The patients will be asked to participate in the study after evaluation by either the principal investigator, co-investigators, or study coordinator. The investigator will discuss the study with the patient and the study coordinator will participate in reviewing details and questions regarding the study if necessary. Patients will be recruited until 40 participants are enrolled.
