TABLE 1.

Previously reported cases of ERCP for choledocholithiasis in patients with underlying SIV

Study	Year	Patient's position	Endoscopist position	Technique	Complications
Venu et al 4	1985	Right lateral	Right side of the table	Patient's position was altered several times to facilitate biliary cannulation.	No
De la Serna‐Higuera et al 7	2010	Prone	Right side of the table	Endoscope was turned 180° clockwise in the stomach followed by the use of a rotating sphincterotome.	No
García‐Fernández et al 8	2010	Right lateral	Right side of the table	“Mirror image” technique. Endoscopic manoeuvres were performed inversely as per normal procedures	No
Lee et al 9	2010	Prone	Right side of the table.	Endoscope was rotated 180° to the right in the stomach. Large‐balloon dilatation was performed after a limited sphincterotomy	No
Mathur et al 10	2012	Prone	Right side of the table.	Endoscope was rotated 180° in the 2nd part of duodenum.	No
Yi Hu et al 1	2015	Supine	Left side of the table	Patient was repositioned to a prone position once the endoscope was in the 2nd part of the duodenum. Endoscope was rotated 180° clockwise in the duodenum with some torsion followed by shortening.	No
Lee et al 2 (Two techniques)	2017	Prone	Right side of the table.	1st: Endoscope was rotated 180° counterclockwise in the stomach and in the duodenum; the endoscope was again shortened using a 180° counterclockwise rotation.	No
				2nd: Endoscope was guided along the lesser curvature, while slowly rotating clockwise.
Ihab I. El Hajj	2017	Prone	Right side of the table.	Endoscope was turned 180˚ to the right in the stomach and, under fluoroscopic guidance, D2 was reached. Another 180˚ torsion to the right was necessary in D2 to retrieve the scope in the short position.	No
Uma Devi et al 3	2019	Left lateral position	Left side of the table.	By turning to the left, scope is advanced into the duodenum. Papilla made enface by counter clockwise rotation (left 90°) and withdrawing the scope.	No
Rocha et al 5	2019	Supine	Left side of the table	Papilla was in the right upper quadrant, and bile duct cannulation was made toward the “1 o'clock” direction. After sphincterotomy, several infracentimetric stones were removed with a Dormia basket.	No
Current study	2020	Supine	Left side of the table.	Endoscope was rotated 180° clockwise in the duodenum with some torsion. A rotatable sphincterotome was used to facilitate biliary cannulation. Extractor balloon was used as an anchor to perform the shortening manoeuvre of the endoscope.	No
