    Abstract:
    Endoscopic retrograde cholangiopancreatography (ERCP) in Billroth II patients is challenging and different endoscopes can be used. We retrospectively analysed 67 ERCP procedures in 38 Billroth II patients focussing on endoscope type and respective technical success and adverse event rate. 33 (49.2 %) ERCPs were performed using a duodenoscope, 87.9 % were successful and 3 were completed with the single-balloon enteroscope. 28 (41.8 %) ERCPs were performed with the single-balloon enteroscope, 82.1 % were successful and 2 were completed with a paediatric colonoscope. For 6 (9.0 %) ERCPs a paediatric colonoscope was used but only 3 (50.0 %) were successful. Overall technical success rate was 82.1 % without difference between the success rate of the duodenoscope and the single-balloon enteroscope. Overall adverse event rate was 10.5 %: 6.1 % duodenoscope,10.7 % single-balloon enteroscope, 33.3 % paediatric colonoscope. The duodenoscope allowed all conventional ERCP procedures, whereas the singleballoon enteroscope required dedicated ERCP catheters and did not allow metallic stent placement. However, the single-balloon enteroscope facilitated access to the papilla and sphincteroplasty allowed direct cholangioscopy. ERCP indications were bile duct stones (53.7 %), cholangitis (20.9 %), chronic pancreatitis (20.9 %), pancreatic cancer (1.5 %) and liver transplantation (3%). Therapeutic ERCP success rate is high in patients with Billroth II gastrectomy using either a conventional duodenoscope or the single-balloon enteroscope, with an acceptable and comparable adverse event rate. The choice of endoscope may depend on local experience, post-operative anatomy and therapeutic indication.
