Core Tip

Core tip: Endoscopic retrograde cholangiopancreatography (ERCP) in patients with surgically altered anatomy is really challenging and requires a well-experienced endoscopist. Understanding the type of surgery, length of the afferent limb, type of endoscope used with choice of proper approach (peroral or transgastric), and compatible ERCP accessories with various endoscopic types are the keys to success. A conventional endoscope and device-assisted enteroscope-assisted ERCP are recommend for short-limb reconstruction with/without a native papilla, while device-assisted enteroscope-assisted ERCP, ERCP assisted by endoscopic ultrasonography, and especially laparoscopic-ERCP are highly recommended for long-limb reconstruction, such as Roux-en-Y gastric bypass with concomitant cholecystectomy.
