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:
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.
286 studies on the registry are indexed under Cholelithiasis; 48 are open to participants now.
This study's enrollment of 130 is below the median of 200 across 83 observational studies indexed under Cholelithiasis.
