About this study
This study intends to explore the success rate and clinical efficacy of modified LERV in the treatment of patients with non-dilated common bile duct (internal diameter ≤10mm) through a non-randomized controlled clinical trial, and to clarify whether modified LERV can be used as the preferred routine treatment for choledocholithiasis secondary to gallbladder stones.
Read the detailed description
Patients with cholecystolithiasis secondary to common bile duct stones requiring surgical treatment during a 3-year period from 2022-6-1 to 2025-3-31 were enrolled in this non-randomized controlled clinical trial. Preoperative diameter of the middle common bile duct was determined by magnetic resonance cholangiography (MRCP) or B-ultrasound measurement. The actual treatment plan of the patients was recorded, including LERV treatment and ERCP+LC treatment. The baseline data and the success rate of stone removal, operation time, postoperative stone residual rate, complication rate, length of hospital stay and hospitalization cost were recorded for observation and follow-up. To determine whether modified LERV can be used as the preferred routine treatment for choledocholithiasis secondary to gallbladder stones.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Modified LERVProcedure or surgery
Also called Pre ERCP+LC
Patients routinely underwent LC. The ligature clamp clamps the distal end of the capsule tube. In this case, you need to perform two steps:
Laparoscopic operation: proximal incision, anterograde placement of guide wire into the duodenum. The catheter was removed and the balloon dilated. The balloon was released and removed when the ERCP was initiated for cannulation. After successful ERCP retrograde placement, the anterograde guide wire was pulled out and the gallbladder was removed.
ERCP procedure: After the anterograde guide wire was observed by duodenoscope, duodenal papilla was placed through a retrograde incision along the anterograde guide wire, and a retrograde cannula was inserted into the common bile duct. Remove stones by dragging them with a net basket or/and balloon. Angiography confirmed that there was no filling defect in the extrahepatic bile duct, and ENBD was indwelled.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study intends to explore the success rate and clinical efficacy of modified LERV in the treatment of patients with non-dilated common bile duct (internal diameter ≤10mm) through a non-randomized controlled clinical trial, and to clarify whether modified LERV can be used as the preferred routine treatment for choledocholithiasis secondary to gallbladder stones.
Detailed description
Patients with cholecystolithiasis secondary to common bile duct stones requiring surgical treatment during a 3-year period from 2022-6-1 to 2025-3-31 were enrolled in this non-randomized controlled clinical trial. Preoperative diameter of the middle common bile duct was determined by magnetic resonance cholangiography (MRCP) or B-ultrasound measurement. The actual treatment plan of the patients was recorded, including LERV treatment and ERCP+LC treatment. The baseline data and the success rate of stone removal, operation time, postoperative stone residual rate, complication rate, length of hospital stay and hospitalization cost were recorded for observation and follow-up. To determine whether modified LERV can be used as the preferred routine treatment for choledocholithiasis secondary to gallbladder stones.

Questions about this trial
What is this clinical trial studying?
An observational study of Choledocholithiasis, run by Shenzhen Second People's Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.

Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 15 Sep 2022. 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 China. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Yongqiang Zhan, Chief physician (13714096676, yqzhan@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Effectiveness evaluation index (time frame: intraoperative). 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 NCT05542784, which also lists 16 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 2022.
