Core tip: In patients with short gastrojejunal “Roux” and bilio-pancreatic limbs, ideally less than 150 cm in length, starting with a (cap-assisted) push-enteroscopy or balloon-enteroscopy approach should offer reasonable diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP) success. When available, short-single-balloon or short-double-balloon enteroscopes should be used, as they allow the use of conventional ERCP equipment, are associated with shorter procedure times, and are easier to manipulate. In patients with Roux-en-Y gastric bypass who have longer Roux and/or bilio-pancreatic limbs, or in patients who have failed prior attempts at deep enteroscopy-assisted ERCP, transgastric laparoscopy-assisted-ERCP should be considered, which is associated with high rates of diagnostic and therapeutic ERCP success.
