Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To investigate feasibility and safety of intraoperative bile duct clearance by sphincter of Oddi balloon dilatation via cystic duct at cholecystectomy.

Primary endpoint: rate of successful bile duct stone clearance (feasibility). Secondary endpoints (safety): rate of peri-interventional complications (injury to the common bile duct, bleeding, injury to surrounding organs: stomach, duodenum, liver) and short-term postoperative complications (bile leak, cholangitis, lipasaemia, pancreatitis, pneumonia). Duration of procedure. Length of hospital stay.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Standard approach to address common bile duct stones is endoscopic retrograde cholangiography (ERC) with sphincterotomy. Those interventions are performed either before or after gallbladder removal (cholecystectomy), thus, requiring at least two interventions. Moreover, ERC with sphincterotomy is associated with a considerable rate of short and long-term morbidity. The main complications are pancreatitis (2-7%), post sphincterotomy bleeding (1-2%), impaired function of the sphincter with reflux of duodenal content to the bile ducts and a consecutive risk for cholangitis, stone recurrence and even a potential higher risk for cholangiocarcinoma.

The aim of this study is to evaluate an alternative surgical approach of bile duct clearance at the time of cholecystectomy. Literature of this approach is scarce; however, it has shown a trend to lower postoperative complications if compared to ERC. The technique of sphincter of Oddi balloon dilatation and bile duct clearance from stones via cystic duct at cholecystectomy has been described in a few case series. These small case series have shown a good success rate of bile stone clearance and low complication rates when applying the balloon dilation technique for smaller stones.

The investigators have used this technique in selected cases with good success as well. However, the technique needs to be assessed regarding feasibility and safety in a consecutive group of patients.
