Laparoscopic cholecystectomy is often used to surgically remove gallbladders and affects about 10% to 15% of the population in the United States; which is roughly about 25 million people. (Liu, 2012) There has been increasing reports in Taiwan from 4.3% to 10.75 that have increased with age and patients ranging from 20 to 39 years old have been reported of having GSD. The study of GSD have been an upward trend in the admission rates for treatment of gallstones since the 1990s and have been varied due to the study design, patient ethnicity, and geographic region. Some factors for these studies include old age, gender, genetics, diet, obesity, diabetes, and the use of oral contraceptives; which have been linked to the increase risk of GSD.

This design is a type of observational study and is used where one or more samples are selected to represent a population and are studied over time. This design is to collect information about the outcome of the interest and any exposure risk factors that may involve. This study is used for people who are disease-free of the study and data is collected from the outcome of the exposure to the risk factors. Cohort studies can be fixed or dynamic. A strength key in using this design would be that it is easy and cheap to use, the subjects can be matched; which reduces any influence of confounding variables, and standardization of outcome is possible. A weakness would be that the outcome of the interest would take time to happen, no randomization, blinding is difficult, or it’s difficult to identify due to confounding variables.
