#1 reviewer :
The DJ stent migration is an intraoperative complication, of course. While placing the guide as antegrade, it has entered through the left orifice. Clinical effects have shown post-operatively. This is extensively explained in the “discussion” section.
#2 reviewer :
The discussion section was extended, adding some comments as suggestedby reviewer.
