Novel use of a balloon dilatation catheter to enable mechanical lithotripsy of difficult common bile duct stones after initial failed attempt: A case report

Endoscopic Biliary Large Balloon Dilation Lithotripsy for Giant and Impacted Stones Removal: A Western Series

BACKGROUND

Endoscopic removal of packed, large, or impacted stones, in which a basket cannot be deployed or is unable to grasp the stone(s), is challenging and inevitably leads to repeated procedures such as stent insertion and extra- or intracorporal lithotripsy. In this study, we describe the results of an alternative stone disintegration technique in a considerable series of patients using an esophageal/pyloric balloon for stone fragmentation or making working space in the bile duct to allow the deployment of the basket, a technique we call endoscopic biliary large balloon lithotripsy.

METHODS

We retrieved data from 1,429 endoscopic retrograde cholangiopancreatographies (ERCPs) from 2 prospective trials performed between 2014 and 2019. Patients with difficult bile duct stones, in which a balloon dilator up to 15 mm was used to crush or increase the working space parallel to the stones in the common or hepatic duct, were included in the study.

RESULTS

From the 1,429 ERCPs, 299 had difficult stones (>1 cm, impacted or multiple stones). Large balloon lithotripsy was employed in 46 cases after endoscopic papillotomy and endoscopic biliary large balloon dilation with failed attempted balloon or basket stone(s) extraction. Failure to clear the bile duct at first ERCP occurred in 4 cases (91.3% of success). Complications were observed in 5 patients (10.8%; 1 perforation, 1 pancreatitis, and 3 bleedings), who were treated conservatively.

CONCLUSIONS

Large balloon lithotripsy, in order to crush the stones or make working room for baskets or balloons in the bile duct, is an effective, safe, and low cost technique for impacted, packed, or giant bile duct stones.

Surgical (Open and laparoscopic) management of large difficult CBD stones after different sessions of endoscopic failure: A retrospective cohort study

OBJECTIVES

For complicated common bile duct stones (CBDS) that cannot be extracted by endoscopic retrograde cholangiopancreatography (ERCP), management can be safely by open or laparoscopic CBD exploration (CBDE). The study aimed to assess these surgical procedures after endoscopic failure.

METHODS

We analyzed 85 patients underwent surgical management of difficult CBDS after ERCP failure, in the period from 2013 to 2018.

RESULTS

Sixty-seven (78.8%) and 18(21.2%) of our patients underwent single and multiple ERCP sessions respectively. An impacted large stone was the most frequent cause of ERCP failure (60%). Laparoscopic CBDE(LCBDE), open CBDE(OCBDE) and the converted cases were 24.7% (n = 21), 70.6% (n = 60), and 4.7% (n = 4) respectively. Stone clearance rate post LCBDE and OCBDE reached 95.2% and 95% respectively, Eleven (12.9%) of our patients had postoperative complications without mortality. By comparing LCBDE and OCBDE; there was a significant association between the former and longer operative time. On comparing, T-tube and 1ry CBD closure in both OCBDE and LCBDE, there was significantly longer operative time, and post-operative hospital stays in the former. Furthermore, in OCBDE group, choledocoscopy had an independent direction to 1ry CBD repair and significant association with higher stone clearance rate, shorter operative time, and post-operative hospital stay.

CONCLUSION

Large difficult CBDS can be managed either by open surgery or laparoscopically with acceptable comparable outcomes with no need for multiple ERCP sessions due to their related morbidities; furthermore, Open choledocoscopy has a good impact on stone clearance rate with direction towards doing primary repair that is better than T-tube regarding operative time and post-operative hospital stay.
