| Summary: | <p>Currently laparoscopic cholecystectomy (LC) and common bile duct exploration (LCBDE) has become the standard surgical procedure for cholecystolithiasis and choledocholithiasis. During the operation cystic duct and vessels are usually controlled by Hem-o-lok clips. However, recently we found clips dropping into CBD in 8 patients during fiberoptic choledochoscope 2-3 months after operation. Therefore, there is risk that clip can migrate during postoperative period, which probably lead to hemorrhage and bile leakage after LC if this occurs within postoperative few days, or even cause recurrent stone in CBD. So, using of Hem-o-lok clips may be not a safe method to control vessels and cystic duct during LC. To our knowledge, this condition has not previously been reported. In our view, other more effective and safe method ligating cystic duct and gallbladder vessels, such as effective and convenient thread knotting method, should be investigated.</p>
