ABCG8, UGT1A1 and Gallstone Disease After Bariatric Surgery
ABCG8, UGT1A1 and Gallstone Disease After Bariatric Surgery: A Genetic Study
The goal of this observational genetic case-control study is to learn whether two specific genetic variants in ABCG8 and UGT1A1 are associated with gallstone disease after bariatric surgery. The study includes adults who have previously undergone bariatric surgery.
The main questions it aims to answer are whether the ABCG8 D19H variant and the UGT1A1 rs6742078 variant are associated with an increased risk of gallstone disease requiring cholecystectomy after bariatric surgery.
Researchers will compare patients who underwent bariatric surgery and later had their gallbladder removed because of gallstone disease with patients who underwent bariatric surgery but did not develop gallstone disease or undergo cholecystectomy during follow-up.
Participants will provide one blood sample for targeted genetic analysis and complete questionnaires about health, previous surgery, medication use, family history, and gastrointestinal quality of life. Relevant clinical information will also be collected from medical records.

Studiebefolkning
Adults who previously underwent bariatric surgery in the Region of Southern Denmark will be included. The study population consists of two groups: cases and controls.
Cases are patients who underwent bariatric surgery and subsequently underwent cholecystectomy due to gallstone disease.
Controls are patients who underwent bariatric surgery and have had at least five years of follow-up without registered gallstone disease or cholecystectomy.
All participants will be identified through hospital records in the Region of Southern Denmark. Participants will provide a blood sample for targeted genetic analysis of selected variants in ABCG8 and UGT1A1 and complete questionnaires on health, medication use, family history, and gastrointestinal quality of life.

ABCG8 carrier status
Tidsramme: 3 years

The primary outcome is the association between ABCG8 D19H carrier status and gallstone-related cholecystectomy after bariatric surgery.
Cases are participants who underwent bariatric surgery and subsequently underwent cholecystectomy due to gallstone disease.
Controls are participants who underwent bariatric surgery and did not undergo cholecystectomy or develop gallstone disease during follow-up.
The association will be estimated by comparing genotype frequencies between cases and controls.
