About this study
Official title: Open Cholecystectomy Among Patients Undergoing Laparoscopic Cholecystectomy in a Tertiary Care Centre: A Descriptive Cross-Sectional Study
In the current era, laparoscopic cholecystectomy is the treatment of choice for symptomatic gallstone disease. The aim of this study is to find out the prevalence of open cholecystectomy among patients undergoing laparoscopic cholecystectomy in a tertiary care center.
Read the detailed description
Laparoscopic Cholecystectomy (LC) is the gold standard surgery for symptomatic cholelithiasis with low mortality and morbidity.1,2 However, 1% to 15% of conversion rate to Open Cholecystectomy (OC) during laparoscopic cholecystectomy has been reported.3 Converted cases were associated with increased perioperative time, complication rates, perioperative costs, the length of hospital stay, and a higher 30-day readmission rate.3,4 Conversion was also associated with complications including bile leak, bile duct injury, or bleeding, requiring reoperation or transfusion, and death. A recent detailed critical review found that preoperative variables like male gender, older age, high body mass index, previous abdominal surgery, the severity of cholecystitis, and gallbladder wall thickness were associated with the higher rate of conversion to OC.4 However, data regarding its prevalence lacking in our setting.
The aim of this study is to find out the prevalence of open cholecystectomy among patients undergoing laparoscopic cholecystectomy in a tertiary care centre.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
No intervention is doneOther
It is a descriptive cross-sectional study so no groups like case/controls are present. All the cases are included in the study.
What is being measured
The primary outcome is the main question the study is designed to answer.
Laparoscopic to Open cholecystectomy
Demographic details, previous attack of biliary pathology, underlying condition, Huang classification of the biliary system are collected. And conversion rate among these patients were calculated with CR= number of converted surgeries/(number of converted surgeries + number of LC surgeries) × 100) Objectives- To identify the prevalence of conversion rate and, To compare the CR among independent variables- Age, Sex, history of previous attack with dependent variable Open cholecystectomy.
Measured: 1 year

Questions about this trial
What is this clinical trial studying?
An observational study of Cholelithiasis and Laparoscopic Cholecystectomy, run by Chitwan Medical College at 1 site in Nepal.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Nepal. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
Laparoscopic to Open cholecystectomy (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05366907, which also lists 9 linked publications.
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 15 Sep 2023.
