Description of intervention(s) / exposure
Single-stage treatment with intraoperative ERCP (ERCP is a technique that combines the use of endoscopy and fluoroscopy to diagnose and treat certain disease of the biliary or pancreatic ductal systems, e.g. biliary stone. Then a flexible endoscope is inserted through the mouth, into the duodenum where the ampulla of Vater exists. The region can be directly visualized with the endoscopic camera. A plastic cannula is inserted through the ampulla, and radiocontrast is injected into the bile ducts. Fluoroscopy is used to look for any pathology such as stones. Then, endoscopist can treat it accordingly. The procedure lasts around 30 minutes) and laparoscopic cholecystectomy (Gallbladder with stones was dissected and removed by minimally invasive surgery with laparoscopic approach by four small wound ports. Intraoperative cholangiogram may be performed also, if needed. The procedure lasts around 90 minutes); Patients will undergo laparoscopic cholecystectomy and intraoperative ERCP simutaneously under general anestheisa.

Treatment: Surgery
Comparator / control treatment
Two-stage treatment with preoperative ERCP (ERCP will be performed under sedation; The procedure lasts around 30 minutes) and then laparoscopic cholecystectomy (The procedure lasts around 90 minutes); Patients will undergo preoperative ERCP and after a short period of clinical monitoring (24–72 hours), laparoscopic cholecystectomy will be received.

Eligibility
Key inclusion criteria
1. Age ranged from 18-75 years old
2. Patients with ultrasonography(USG)/magnetic resonance cholangiopancreatography (MRCP)/computed tomography (CT) scan evidence of gallbladder stones and common bile duct (CBD) stones
3. Patients recovered from episode of acute cholangitis or biliary pancreatitis, and were treated with ERCP and temporary biliary stenting for the biliary stone obstruction during acute phase. Patients were randomized only if they demonstrated evidence of resolved acute episode, as determined by a decreasing white cell count, bilirubin level, fever and reduced abdominal pain

Summary
Brief summary
The ideal management of common bile duct stones (CBD) in the era of laparoscopic cholecystectomy remains controversial. However, ERCP remains the prevailing method of treating CBD stones, but its ideal timing in respect to laparoscopic cholecystectomy is not defined yet.
