Title: Comparison of endoscopic retrograde cholangiopancreatography outcomes between cap-
fitted forward and side viewing endoscopes in patients with Billroth II anastomosis
Version: 3 Date: 16 Nov 2022
Reviewer's report:
I did agree with author discussion about  limitations of your study.
Precut sphincterotomy or fistulotomy in CE group increase  risk of post ERCP pancreatitis.
Please comment: The reason that they prefer to use this technique rather than standard
cannulation with EST or EPBD.  It may be the reason that CE group had more pancreatitis.
Please mention about  SE technique, rate of intubation failure, change from SE to CE?
