Brief Summary
This prospective clinical cohort study will include patients with gallstones and abdominal pain scheduled for surgery (laparoscopic cholecystectomy). Data on quality of life, abdominal pain, gallstone disease, and patient characteristics will be collected before surgery. The outcomes will be assessed three months following surgery and will primarily be determinants for resolution of pain. The aim is to make a prediction score that may aid clinicians and patients in decision making about surgery.

Outcome Measures
Primary Outcomes (1)
Prediction model for resolution of pain
To build and validate a prediction model for resolution of pain (VAS≤4) following laparoscopic cholecystectomy
From baseline before surgery to follow-up at three months after surgery
Secondary Outcomes (1)
Changes in symptoms following surgery
From baseline before surgery to follow-up at three months after surgery
Study Arms (1)
Patients with gallbladder stones and biliary pain that undergo laparoscopic cholecystectomy
Patients are included if they have gallbladder stones on abdominal ultrasound examination, abdominal pain expected to be due to gallstones by the clinician and scheduled for elective laparoscopic cholecystectomy. Patients with either a history including biliary interventions or complicated gallstone disease such as pancreatitis, cholecystitis or bile duct stones will be excluded.
Interventions
A surgical removal of the gallbladder through laparoscopy
Eligibility Criteria
The population will include patients referred to outpatient clinics either from primary care general practitioners or from a hospital department. Currently six hospitals are included from four out of five Danish health care regions.
You may qualify if:
- Ultrasound examination with presence of gallstones and description of size, number and presence of stones in infundibulum or cystic duct
- Abdominal symptoms believed to be caused by symptomatic uncomplicated gallstones
- Indication and candidate for elective laparoscopic cholecystectomy
- Above 18 years of age
- Ability to give oral and written consent
- Ability to understand, speak and read Danish
- Ability to receive digital post
You may not qualify if:
- History of complicated gallstone disease including acute cholecystitis, pancreatitis, common bile duct stones, or cholangitis
- Previous sphincterotomy
- Abnormal liver function test (ALAT/ASAT, alkaline phosphatase, bilirubin) without magnetic resonance cholangio-pancreatography or endoscopic ultrasound to rule out common bile duct pathology
- Indication for urgent cholecystectomy
- Current pregnancy
