Laparoscopic Transcystic Common Bile Duct Exploration: T-Shaped Incision of Cystic Duct with FREDDY Laser Lithotripsy.

Abstract

Optimal laparoscopic techniques for management of gallstones concomitant with common bile duct (CBD) stones remain under debate. The aim of this study was to evaluate a novel approach to managing gallstones concomitant with large or impacted CBD stones through a modified laparoscopic transcystic CBD exploration (LTCBDE) with frequency-doubled double-pulse neodymium:YAG (FREDDY) laser lithotripsy. This retrospective review includes 32 consecutive patients with gallstones concomitant with large or impacted CBD stones who were offered LTCBDE with FREDDY laser lithotripsy between June 2012 and December 2014. Demographic, perioperative, and follow-up data were collected and analyzed retrospectively. CBD stone clearance was achieved for all patients. There were 13 males and 19 females, among whom there were three patients with a history of abdominal surgery. The diameter of the CBD ranged from 10 to 20 (mean 15.1) mm, and the number of CBD stones ranged from 1 to 5. CBD stones ranged in diameter from 9 to 18 (mean 11.7) mm and 9 patients had stones that were impacted in the CBD. The mean operative time was 123 ± 18 minutes with a range of 72 to 155 minutes. The mean length of postoperative hospital stay was 5.3 (range 4-7) days. All patients recovered normally without morbidity or mortality. The modified LTCBDE with a T-shaped incision of the cystic duct and FREDDY laser lithotripsy is a safe and effective means of managing gallstones concomitant with large or impacted CBD stones.
