Benchmarks in Acute Laparoscopic Cholecystectomy
An observational study of Gallbladder and Gall Stones (&Amp; [Calculus - Gall Bladder]), run by Region Östergötland.
Trial summary
The aim of this observational cohort study is to define peri- and postoperative reference values for acute laparoscopic cholecystectomy, using the achievable benchmarks of care methodology (ABC™).

About this study
Official title: Benchmarks in Acute Laparoscopic Cholecystectomy - a National Registry Study
The aim of this observational cohort study is to define peri- and postoperative reference values for acute laparoscopic cholecystectomy, using the achievable benchmarks of care methodology (ABC™). Another aim is to develop adjusted reference values for groups with a risk factor of severe postoperative complications. The goal is to spur quality improvement initiatives.
Read the detailed description
The data source is the Swedish patient registry GallRiks, a prospective quality registry for gallbladder surgery and endoscopic retrograde cholangio-pancreatography (ERCP). The time frame will be 2015-2023. Register variables related to surgical quality will be analyzed, such as postoperative complications, perioperative adverse events, surgical duration and length of stay. The study will analyze data for the time of surgery and up to 30 days afterwards. As the researchers do not yet have the data available, the exact number of enrolled participants can not yet be given.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Laparoscopic cholecystectomyProcedure or surgery
The intervention in this study is urgent, not elective. The conditions for the surgery are therefore different: any time of day, the surgeon on shift, the state of the patients.
| Study group | Role | What they receive |
|---|---|---|
| Acute laparoscopic cholecystectomy | Patients with gallbladder inflammation. ERCP may be involved if a gallstone is detected in the common bile duct perioperatively. Receives: Procedure: Laparoscopic cholecystectomy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Benchmark values of acute laparoscopic cholecystectomy
The study will use the ABC methodology to identify reference values of surgical duration (minutes), perioperative cholangiography, conversion to open surgery and adverse events
Measured: Day of surgery
Postoperative benchmark values of acute laparoscopic cholecystectomy
The study will use the ABC methodology to identify reference values of postoperative variables: hospital length of stay (days), abscess/infection, bleeding, biliary leakage, readmission, reoperation
Measured: 0-30 days after surgery
Secondary outcomes (1)
Adjusted benchmarks for severe complications
Univariable and multivariable logistic regression analysis will be performed to detect any risk factor for severe complications after acute laparoscopic cholecystectomy. The factors to be investigated are body mass index (kg/m2), age (years), gender, smoking, cardiovascular disease, pulmonary disease, diabetes, immunosuppressive treatment, and treatment with anticoagulants. Adjusted benchmarks will be calculated for factor(s) that in multivariable logistic regression analysis are identified as individual risk factor(s).
Measured: 0-30 days after surgery

The record says: finished, as of the sponsor's last update on 31 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Benchmark values of acute laparoscopic cholecystectomy (time frame: Day of surgery). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Dec 2024.
