A simple novel method of biliary drainage: gallbladder serosal wrapping after open choledochotomy

In this study, we developed a new, simple technique for biliary drainage after open choledochotomy of choledocholithiasis. After the absence of intraductal stones was established by operative cholangiography and cholangioscopy, preserved gallbladder serosal wrapping was performed by inclosing a polyethylene tube (C-tube), which was inserted from the cystic duct to optimal portion of choledochus, within the gallbladder bed, with continuous suture of the preserved serosa of the gallbladder using 4-0 absorbable thread. This method was used in the cases of 8 patients. There was neither bile leakage nor residual bile duct stones. The C-tube could be removed after 7 days following surgery. The average hospital stay was 12.3 +/- 6.6 days. We propose that this procedure would be very simple and useful, and it would significantly shorten hospital stays after open choledochotomy of choledocholithiasis.
