Endoscopic papillary large balloon dilation for bile duct stones in elderly patients

AIM: To investigate whether endoscopic papillary large balloon dilation (EPLBD) can be safety and effectively performed in patients aged ≥ 80 years.

METHODS: Lithotomy by EPLBD was conducted in 106 patients with bile duct stones ≥ 13 mm in size or with three or more bile duct stones ≥ 10 mm. The patients were divided into group A (< 80 years) and group B (≥ 80 years). Procedure success rate, number of endoscopic retrograde cholangiopancreatographies (ERCP), and incidence of complications were examined in both groups.

RESULTS: Group B tended to include significantly more patients with peripapillary diverticulum, hypertension, hyperlipemia, cerebrovascular disease/dementia, respiratory disease/cardiac disease, and patients administered an anticoagulant or antiplatelet agent (P < 0.05). The success rate of the initial lithotomy was 88.7 (94/106)%. The final lithotomy rate was 100 (106/106)%. Complications due to treatment procedure occurred in 4.72 (5/106)% of the patients. There was no significant difference in procedure success rate, number of ERCP, or incidence of complications between group A and group B.

CONCLUSION: EPLBD can be safely performed in elderly patients, the same as in younger patients.

Endoscopic papillary large balloon dilation for removal of bile duct stones

AIM: To investigate the efficacy and outcomes of endoscopic papillary large balloon dilation (EPLBD) for bile duct stones in a multicenter prospective study.

METHODS: Lithotomy by EPLBD was conducted in 124 patients with bile duct stones ≥ 13 mm in size or with three or more bile duct stones ≥ 10 mm. After endoscopic sphincterotomy, the papilla was dilated using balloons 12-20 mm in diameter fitting the bile duct diameter.

RESULTS: The success rate of first-time lithotomy was 86.3% (107/124) and the final lithotomy success rate was 100% (124/124). Lithotripsy was needed in 10 of the 124 (13.6%) patients. Adverse events due to the treatment procedure occurred in 6 (4.8%) patients, all of which were mild. Performing large balloon dilation after endoscopic sphincterotomy in patients with large stones or multiple stones in the bile duct is considered to ensure the safety of treatment and to reduce the need for lithotripsy.

CONCLUSION: It is suggested that treatment by EPLBD for large bile duct stones may be safe and useful.

Endoscopic extraction of large common bile duct stones: A review article

Since therapeutic endoscopic retrograde cholangiopancreatography replaced surgery as the first approach in cases of choledocolithiasis, a plethora of endoscopic techniques and devices appeared in order to facilitate rapid, safe and effective bile duct stones extraction. Nowadays, endoscopic sphincterotomy combined with balloon catheters and/or baskets is the routine endoscopic technique for stone extraction in the great majority of patients. Large common bile duct stones are treated conventionally with mechanical lithotripsy, while the most serious complication of the procedure is “basket and stone impaction” that is predominately resolved surgically. In cases of difficult, impacted, multiple or intrahepatic stones, more sophisticated procedures have been used. Electrohydraulic lithotripsy and laser lithotripsy are performed using conventional mother-baby scope systems, ultra-thin cholangioscopes, thin endoscopes and ultimately using the novel single use, single operator SpyGlass Direct Visualization System, in order to deliver intracorporeal shock wave energy to fragment the targeted stone, with very good outcomes. Recently, large balloon dilation after endoscopic sphincterotomy confirmed its effectiveness in the extraction of large stones in a plethora of trials. When compared with mechanical lithotripsy or with balloon dilation alone, it proved to be superior. Moreover, dilation is an ideal alternative in cases of altered anatomy where access to the papilla is problematic. Endoscopic sphincterotomy followed by large balloon dilation represents the onset of a new era in large bile duct stone extraction and the management of “impaction” because it seems that is an effective, inexpensive, less traumatic, safe and easy method that does not require sophisticated apparatus and can be performed widely by skillful endoscopists. When complete extraction of large stones is unsuccessful, the drainage of the common bile duct is mandatory either for bridging to the final therapy or as a curative therapy for very elderly patients with short life expectancy. Placing of more than one plastic endoprostheses is better while the administration of Ursodiol is ineffective. The great majority of patients with large stones can be treated endoscopically. In cases of unsuccessful stone extraction using balloons, baskets, mechanical lithotripsy, electrohydraulic or laser lithotripsy and large balloon dilation, the patient should be referred for extracorporeal shock wave lithotripsy or a percutaneous approach and finally surgery.
