Laparoscopic transcystic duct common bile duct exploration

Abstract

The modern era of common bile duct (CBD) surgery started with Mirizzi, who introduced intraoperative cholangiography in 1932. Intraoperative choledoscopy had been developed as an adjunctive to intraoperative cholangiography, which helped to detect CBD stones in an additional 10% to 15% of instances that otherwise would have been missed. Findings have shown choledochoscopy to be an important technique for efficient and effective management of CBD stones. Efforts to treat patients with common duct stones in one session and to avoid the potential complications of endoscopic sphincterotomy resulted in several laparoscopic transcystic CBD (LTCBDE) techniques. The techniques of transcystic stone extraction include lavage, trolling with wire baskets or biliary balloon catheters, cystic duct dilation, biliary endoscopy, and stone retrieval with wire baskets under direct vision and antegrade sphincterotomy, lithotripsy, and catheter techniques. The indications for LTCBDE are filling or equivocal defects at cholangiography, stones smaller than 10 mm, fewer than 9 stones, and possible tumor. The contraindications are stones larger than 1 cm, stones proximal to the cystic duct entrance into the CBD, small friable cystic duct, and 10 or more stones. Experience with LTCBDE shows that the approach is applicable in more than 85% of cases, with a success rate of 85% to 95%. It also is shown to be more cost effective than postoperative endoscopic retrograde cholangiopancreatography. Recent developments in LTCBDE have focused mainly on implementation of robotically assisted surgery and new imaging methods such as magnetic resonance cholangiopancreatography with three-dimensional virtual cholangioscopy and three-dimensional ultrasound. Further technological advances will facilitate the application of laparoscopic approaches to the common duct, which should become the primary strategy for the great majority of patients.

Stone clearance and risk factors for failure in laparoscopic transcystic exploration of the common bile duct

“…The scope of the study is instead focused on evaluating short term outcome of LTCE as well as pinpointing risk factors for failure in stone clearance. A stone clearance success rate of 85% is well in line with the results of previous studies concerning LTCE [16], and moreover well comparable to the stone clearance results that can be achieved with ERC with ES [17], which is the main alternative to the transcystic approach. The ERC can be made either pre-, per-, or postoperatively [8,9,12].…”

Laparoscopic transcystic bile duct exploration: the treatment of first choice for common bile duct stones

“…There is a predictably small increase in the overall intraoperative time (mean, 25 min; Table 2). The success of TCE described in the current literature varies from 63% to 95%, and was 55% in our study [18,19]. This relatively lower TCE rate was thought to be mainly due to a majority of our patient population (84%) having large stones (mean size 10 ± 4 mm) in their bile ducts and due to the lack of an ultrasound lithotripter in our setup.…”

Laparoscopic common bile duct exploration and holmium laser lithotripsy: a novel approach to the management of common bile duct stones

“…A transcystic approach to LCBDE, shown to be effective in most cases, has the advantage of avoiding choledochotomy, which requires suture repair [4,5]. Moreover, laparoscopic cholecystectomy with simultaneous laparoscopic bile duct exploration also offers the advantage of avoiding an extra procedure and the potential complications of ERCP.…”
