Laparoscopic management of common bile duct stones: transpapillary stenting or external biliary drainage?

To date, the management of common bile duct stones (CBDs) is still controversial. If laparoscopic exploration is performed and biliary decompression is needed after stone removal, the placement of a laparoscopic transpapillary stent shows promising results in avoiding T-tube-related complications.

Between January 2007 and May 2012, a series of 48 patients who underwent biliary decompression after laparoscopic common bile duct exploration (LCBDE) to treat choledocholithiasis was retrospectively analyzed. The results in patients with transpapillary stent placement (TS=35) were compared with those who had an external biliary drainage (EBD=13).

LCBDE and TS placement was achieved either by a choledochotomy or through the cystic duct. There was no mortality in our series. Patients with an external biliary drainage (EBD) had more surgery-related complications (P<.0001) and a longer hospital stay (P=.03). Postoperative ERCP to remove the TS was successful in all cases.

Laparoscopic TS is a safe method in the treatment of selected patients with CBD stones that can be achieved without having to perform a choledochotomy. Because of the lower morbidity and the shorter hospital stay compared with EBD, it should be considered as a first approach whenever biliary decompression is needed after LCBDE.
