About this study
Official title: Comparison of Ultrasonography Findings With Intraoperative Findings in Patients Undergoing Laparoscopic Cholecystectomy for Gall Stone Disease
This research is designed to correlate between intraoperative status of gallstone disease patients with their USG findings.
The key question it aims to answer is:
Does the ultrasonography predict laparoscopic cholecystectomy will be difficult?Further analysis will aim to reveal:
- Are there any specific parameters of ultrasonography that immediately concern the operating surgeon?
- Should surgeons depend on the ultrasonography reports to counsel the patients differently?
Read the detailed description
Laparoscopic Cholecystectomy is the most common minimally invasive procedure and cholelithiasis is the major indication. It is associated with early recovery and better outcome yet not all patients have smooth recovery. USG is commonly used to diagnose gallstone disease. Not all cholecystectomies are straight forward and some will always face problems. So it is an added benefit if certain factors can predict such unexpected events and make surgeons alert for the same. From this study the investigators attempt to identify such factors in USG by comparing it with intraoperative findings and draw conclusions.

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07530874, which also lists 3 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.
