There is currently no consensus regarding optimal endoscopic intervention, and there are no controlled data to indicate the optimal number, configuration, size, type and length of endoprostheses required for successful management of biliary leaks after laparoscopic cholecystectomy.[9,15-17] Experimental data show that flow rates are better in vitro through straight than through pigtail stents, and fistula closure is more rapid in dogs with stents compared with sphincterotomy alone.[8,10,18,19] The ideal duration for biliary stenting is not known, and has varied from 3 to 8 weeks in previous reports.[10,13,15,16] In this study, we used single 10 Fr plastic stents after a conservative sphincterotomy for access and to facilitate stent insertion.
Although there are many causes of DJ stenting in the cardiovascular system, the appropriate endoscopic procedure with intraoperative real-time imaging might help prevent complications, such as fistulas, erosions, displacements and migrations of ureteral pigtail stents, including the rare event of intravascular placement or migration.
