An observational study in Choledocholithiasis, sponsored by Shenzhen Second People's Hospital. Status unknown at 1 site in China. Open to participants aged 18 Years to 85 Years. Per ClinicalTrials.gov, last updated 2022-09-15.
Sponsored by Shenzhen Second People's Hospital · Observational
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.
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.

1、18 years ≤ age \<85 years 2、clinical diagnosis of choledocholithiasis secondary to cholecystolithiasis and middle choledocholithiasis (MCBD) diameter ≤10mm; The diameter of MCBD was based on MRCP measurements. If MRCP could not be performed, CT images were used as reference, and B-ultrasound measurements were used as the standard.
3、 Good cardiopulmonary function, anesthesia evaluation tolerance under general anesthesia laparoscopic + endoscopic surgery.

Exclusion Criteria:
1、 Intrahepatic bile duct stones with indications for surgery, and need simultaneous surgery; 2、 Patients with choledocholithiasis >2 cm or a large number of stones were difficult to remove; 3、 Patients with malignant hepatobiliary and pancreatic tumors or biliary tract malformations; 4、 Severe patients with severe pancreatitis and septic shock before operation; 5、Patients with previous gastric and duodenoscopic surgery history and interruption of gastroduodenal continuity; 6、 Severe partial stenosis of the upper gastrointestinal tract (from the oral cavity to the second duodenum), which is expected to be inaccessible to the duodenoscope.

Procedure: Modified LERV
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.
