Endoscopic evaluation of the defunctionalized stomach by using ShapeLock technology (with video)

Endoscopic Retrograde Cholangiopancreatography with Single-Balloon Enteroscopy Is Feasible in Patients with a Prior Roux-en-Y Anastomosis

“…Reliable identification of the biliary jejunal limb may be a persistent challenge, as was seen in three of the four cases described here (two delays; one failure to localize the enteroenterostomy). Stable enteroscope positioning for cannulation and device delivery is also a challenge, though efforts are underway to design novel devices to assist in the latter [22]. Finally, in the recent past, many accessory devices (with the exception of the 13-mm balloon catheter) typically used for routine ERCP have not been commercially available for use through an enteroscope.…”

Single-balloon enteroscopy effectively enables diagnostic and therapeutic retrograde cholangiography in patients with surgically altered anatomy

“…In recent years, deep intubation of the afferent biliary limb has been achieved by using a ShapeLock overtube, 12 spiral or rotational enteroscopy, 13 and double-balloon enteroscopy (DBE). [14][15][16][17][18] However, data on the use of spiral enteroscopy and the ShapeLock overtube are limited, whereas DBE requires specialized equipment and expertise that are not widely available.…”

Retrograde Endoscopic Cystgastrostomy for Pancreatic Pseudocyst Drainage after a Prior Roux-en-Y Gastric Bypass

“…Technical limitations (i.e., length of conventional endoscopes) often do not allow visualization of the proximal afferent limb and excluded stomach [2]. In addition, the acute angulation of the gastrojejunal anastomosis and the increasing length of the Roux limb with RYGBP performed in recent years make endoscopic access to the afferent limb even more difficult [3]. Use of colonoscopes, balloon enteroscopes, and endoscopic passage through a percutaneous gastrostomy allows the endoscopist to circumvent these challenges [2,4,5].…”
