Gaps in our knowledge of the outcomes of endoscopic ultrasound-directed transgastric endoscopic retrograde cholangiopancreatography (EDGE).

1	Additional risk of same-session ERCP vs. delayed ERCP
2	Clinical significance of stent migration outside of stent mal-deployment requiring separate intervention such as surge
3	Clinical significance of a persistent gastrogastric or jejunogastric fistula in terms of weight gain and additional complications
4	Method required, if any, to close gastrogastric or jejunogastric fistulas and best time to assess for fistula closure on follow-up
5	Clinical significance of the location of fistula (gastrogastrostomy vs. jejunogastrostomy)
6	ERCP-specific complication rate of EDGE and how it compares to standard ERCP complication rates in normal anatomy and in laparoscopy assisted-ERCP
